Italian Army Aviation helicopters, main battle
A129, is a dedicated light helicopter gunships, nicknamed Developed by the Italian Agusta A-129 Mongoose was the first European-type gunship helicopters, is also the first real test of an experienced European countries, the armed helicopter. Beijing Air Show in 2001 and 2004 Zhuhai Airshow, Agusta mongoose are deliberately brought the model, caused a strong interest in domestic military enthusiasts.

design background design of advanced combat engine integrated multi-task system (IMS) concept of TOW missile aiming system and free choice of project development control rocket A-129 Development of the international-type setting international mongoose-type characteristics, as the red appearance of the cabin before the fire control system aiming system Hellfire missile cannon Missile Development and the U.S. military operations in Vietnam have shown the important role of the helicopter. August 1972, the U.S. Army AAH program of advanced attack helicopter tender, which plans to eventually create a future famous At the same time, Europe as a bulwark against Soviet armor the first line of a flood of similar projects are brewing. However, when the Italian Ministry of the total units in 1972 to seek tentative expressed the need for a dedicated anti-tank helicopters into, this is the first European. There are two technologies of the Italian elections: the purchase of ready-made helicopters (such as AH-1) or to improve a country now helicopter. Italian AB-205 helicopters were mounted TOW missile test, but the test results but does not allow the Italian Army satisfaction. And if they buy expensive AH-1, and this also makes it difficult to accept the Italian aviation industry. On balance, the Italian Army Aviation (ALE) Agusta joint decision to shift A-109 helicopters were significantly modified, the project name is ELECC light patrols,
nike air force one, anti-tank helicopters. Italian Army Aviation and this corresponds to a plan is to develop another multi-purpose helicopters, medium-sized family,
nike air force one low, including battlefield support, transportation, C3, and reconnaissance helicopter search. Results, because of funding problems, and ultimately only the first anti-tank helicopter project to continue. For many considerations, the Italian in this project did not exclude cooperation with other countries. 1975 Agusta agreement with the German company MBB and started A-MBB115 light attack helicopter design, but because of their different operational needs, and design can not agree on the division of labor, cooperation plan finally died. Germany into the development of the national MBBBO-105 helicopters to improve the armor enhanced PAH-l (in German Later, PAH-1 became one of France jointly developed a new type of heavy German anti-tank helicopters PAH-2 (or HAC, or After a long and difficult gestation, PAH-2 Tiger eventually develop into armed helicopters. Development plan in cooperation with Germany after the fall, Agusta developed a transitional single light anti-tank helicopters, developed was similar to other European countries by a combination of helicopters and anti-tank guided missile weapon systems, such as Britain's Bobcats / Tao, a small antelope, France / Haute and German PAH-l / Holt. Italy is similar to model A-109A / improved on the basis of pottery. The difference is that the European allies, Italy, this helicopter is only a transitional model. Other countries at this time no further development plans.
A129 helicopters
1978 年 3 months, with the Italian Army Agusta respectively, 60% ~ U30% stake in joint venture development of new helicopters, the A a 129. Agusta a generous re-read the argument. 4/4.5 ton of PAH-2 in Italy at that time seemed too big for the demand. Similarly, based on a 109 A design concept is also inappropriate. Army basic requirement is the use of TOW missiles, helicopters, most tasks can be more than 3800 kg weight of a small (but later mongoose or beyond this weight), cruising speed 250 km / h, sea-level climb rate of 10 m / s, without ground effect hover height of 2000 meters, life time of 2 hours and 30 minutes. According to this index, Agusta for a new conceptual design. Finalize the program for the serial two-seat layout, after the three-point landing gear, with short wings for mounting arms, and two four-rotor engine nacelle, concept aiming system installed in the turret on the nose. In some respects, it is a bit like a first flight in 1975, a U.S. Hughes YAH 64. To November 1982 A basic design of a 129 has been completed. A 129 in a body, all reflect the needs of the Italian Army of anti-tank urgent. The first helicopter delivered no night fighting capability, but in the subsequent development has been improved. The aircraft's main equipment is the eight anti-tank missiles, but no machine guns or cannon. In addition, as a light helicopter gunships, A-129 almost no armor protection, and its compact size, rely mainly on survival, and superb flight performance, low-infrared radiation and low noise (these characteristics is much smaller than a 64 AH). Can say that in the initial stage, part of the lack of vision of the Italian Army officials on the development of the Mongoose played a negative role. Compared to Apache, it is too fragile, and instruments equipped with only eight short-range TOW missile appears to lack firepower. A129 design used by the layout of the armed helicopter, the fuselage, tandem tandem cockpit, the co-pilot / striker in front, after the pilot cabin in a high,

are falling machine energy absorption seat. Cantilever wing with a short body, a composite material, is located in the cockpit after the plane after the rotor shaft. Each short-wing aircraft equipped with two plug-in, you can plug 1,000 kg of weapons. Fixed crash-resistant landing gear after 3:00. Aluminum body structure design is mainly composed of beams and frame structure of conventional semi-monocoque. Position in the fuselage and fuel tanks are made from the honeycomb panel. Composite of the total body weight (except for the engine weight) 45%, accounting for 16.1% of empty weight, mainly for the nose fairing, tail boom, tail inclined beams, engine nacelle and the canopy frame and maintenance of siding. External appearance of all the body (except the blade and the paddle wheel outside) area of 50 square meters, of which 35 square meters for the composite material. The rolled-style head box and the forward fuselage separated from the rolled Beam used to protect the occupants. Engine and other critical parts have armor protection. All machines are able to absorb the infrared spray coating. 12.7 mm armor-piercing body can withstand, and to meet U.S. military standards MIL-STD-1290 anti-crash standards. To 11.2 meters in specific / s vertical drop speed crash landing, and to 13.1 m / s vertical speed bumps hard wall, the need to maintain the viability of 95%, and all moving parts are not allowed to enter the cockpit. At the same time reduce the internal volume cockpit shall not exceed 15%). It should be said early in the development of A-129, Agusta draw extensively on the experience of the parties. But it also has its own technical features. For example, the light weight composite materials accounting for 45% of body weight (excluding engines), external surface area of 70%. Mature and concise with all articulated four semi-rigid main rotor and tail rotor 2 triangular articulated. Main rotor shaft installed on the three-dimensional spherical elastic (one per leaf), which is used in the attack helicopters for the first time, the advantage is not on the propeller hub and bearing lubrication, and reduced resistance and helicopter rotor vibration, even is making a sharp turn such as 90 degrees higher than the load maneuvering. Main rotor with carbon fiber and Kevlar girder manufacturing, composites skin, front and rear honeycomb material cause, the rotor leading edge of anti-wear package made from the stainless steel blade tip easily replaced. All mechanical link and the moving parts are housed inside the rotor shaft to prevent foreign object damage and freezing, and reduced radar signal. A rotor of a 129 23 mm artillery shells can withstand a direct hit and be able to cut the 15 cm thick trunk. A 129 A thick hollow rotor rotation axis, can be very easy to install mast reconnaissance and targeting systems. And as the main control link and the rotating tilted disk space available. In addition the system can significantly reduce the helicopter's radar reflection. Meerkats live by the standards of military STDl290 crash, it is the second UH a 60, AH-64 after the third use of the standard helicopter. Hydraulic shock absorber with two poles of the main landing gear strut and Martin Baker, fall protection for a seat, coupled with the body deformation designed to protect the aircraft to 11.2 m / s vertical velocity and 13.1 m / s down to the horizontal velocity ground, the crew has a 90% survival rate. The landing gear to protect the body and skin in the 4.57 m / s A body of a 129 maximum allowed overload +3.5 G for a 2G.

pilot's burden, even in the current armed helicopters, this cabin is very advanced. Airborne aircraft core of the system is a set of IMS systems (integrated multi-tasking system), the system consists of Agusta Harris jointly developed with the United States. Agusta responsible for the IMS system hardware and write the program, the program is written in assembly language. IMS is a two redundant system that uses two sets of computer units. Through this system, each crew can monitor and control the navigation, communication, display (forward looking infrared systems, head mounted display system, the helicopter infrared navigation system) and the weapon system and all flight parameters (fuel, electrical systems, hydraulic transmission, etc.). Here the cabin, each crew has a monochrome look-down display, the control panel on the left Control key. The system is a high degree of automation, in addition to some basic flight parameters and important warning lights and engine parameters display, mongoose pointer pilot cockpit instrumentation and traditional toggle switches greatly reduced. System can use the standard Greek alphabet keyboard programming, flight plan information can be uploaded from an external data storage system. Regional navigation system up to 100 nodes can be incorporated, and can store up to 100 pre-set HF / VHF / UHF frequencies. 1553B data bus through the IMS system with the radar altimeter, fire control systems, flight navigation system link, including Litton Italian company LISA4000 (attitude and heading reference system) platform, the Italian company Marconi Doppler ANV35l sensors, EFl001-1 radar altimeter, the Italian company Marconi ARG80ADF GTl703 vertical gyro and aviation electronics company GEC a 03-004 IS air data system. Digital AFCS (Automatic Flight Control System) that allows aircraft to terrain following mode (NOE) or used for aiming and firing automatic weapons, the stability of the mode of flight. In the prototype, the autopilot mode selection is controlled by the rudder pedal to control, and now re-installed in a special conversion unit. A is currently in service a 129 Amur's SRTl70/EB4 installed HF radio transceiver, dual mode multi-band radio and the Amur SRT65l Italy SIT42lT/1553 IFF. Meerkats also have advanced and complete electronic defense system, which is also linked with the 1553B data bus, including a ELTl56-05 radar warning receiver, Marconi A pair of Italian company RALM a laser warning receiver, a radar ELT554 AN/ALQ-144V1 infrared jammer and a jammer. View aiming system equipped with the original plan for a 129 A MMS (Mast concept aiming system) due to cost reasons, were temporarily abandoned,

School Systems in attack and navigation. Italian Army Aviation delivered the first of the Prototype nose in the bottom of the tower to install a performance slightly worse turn some of the Hughes TOW M65 targeting system. Both systems are competitive in 1987, eventually upgrading HeliT0W system by the Swedish victory. HeliTOW is a high resolution, with 3 times and 12 times magnification view of the all-weather day and night sight system. It combines a second generation forward looking infrared system (using 8 to 12 micron wavelength) and Nd YAG solid-state laser generator. FLIR system has the same optical system with magnification. Improved HeliTOW able azimuth angle of 240 degrees and the level of rotation within 50 degrees. Optical systems and laser range finder to transfer data through the data bus to the IMS system, located in the cockpit of the military prosecutor to obtain precise target coordinates, and distance information. In the upper nose of the transfer of a tower equipped with a second forward-looking infrared system, the system is mainly used for the rear pilot. Is called HIRNS (Helicopter infrared guided dirty system), its a thermal imaging infrared device installed in a servo platform. Azimuth and elevation angle HIRNS were plus or minus 130 degrees and +20 degrees to 60 degrees. HeliTOW and HIRNS turret can turn 180 degrees in order to protect the optics from damage while in flight. Transmitted by the infrared imaging system HITNS the same time for the pilot and weapons control / pilot to use, they wear a Honeywell integrated helmet display device. The thermal imager by the HeliTOW images obtained through the concept of arms control officer aiming at the integrated helmet display system displays device. The first application of such devices in the AH is a 64, including a cockpit helmet mounted on the tracking system, which allows the pilot arms control official, or you can just simply turned around and stare at the target goal of tracking and targeting. Originally the system can significantly improve the efficiency of gun control, although the Italian army aviation A-one 129 (early) and not equipped with artillery. Aiming point, because it can show it can also be used to launch its non-controlled rocket. TOW missiles and rocket-free control of a 129 A selection of the main anti-tank weapon is a BGM 71 TOW anti-tank missiles. Helicopters equipped with TOW missile (BGM a 7lA / B) was upgraded
A129 helicopters
for the Tao of a I (BGM a 71C) and the Tao of a 2II (BGM a 71D / E) type. TOW anti-tank missile a maximum range of 3,750 meters, the range of the first helicopter in the Soviet Union early enough to ensure short-range air defense systems (such as the Sum of a 7 or 20-30 mm anti-aircraft artillery) outside the effective range of launch, but in the face of a range of Sam A further 15 (9M330 Doyle), Sam A 18 (9K38-pin) and the Tunguska and other new systems, becomes insufficient. But like all the open space or air to air missiles, as if giving a higher launch velocity vector (relative to the fixed vector), TOW missile's effective range will increase. The helicopter to 185 km / h speed flight launched TOW missile range would increase to about 4,000 meters. At this point, the missile to fly the entire distance be at least 20 seconds. When launching the missile, the helicopter front of the arms control officials have to type with image stabilization systems targeting reticle on the target firmly pressed. Missile flight, the tail of the infrared beacon to send a strong infrared signal. Aiming device at the helicopter view of a missile tracker will be with the relative angle of changes in the line of sight guidance signals. The signal is converted into control commands, and through the thin copper wires to missiles. Gradually close to the concept of signal control the missile in the line of sight aiming system, and line of sight is always suppress the target. Missile flight, the only member of the task of manipulating the target line is to always suppress the target, then the pilot can not adjust the angle of view of aiming system (about 110 degrees field of vision), or target will be lost. A cabin in a 129, these adjustments limit eye-catching landmark in the square boxes on the flight controller. Like any other kind of helicopter gunships as mongoose is also equipped with unguided rockets. A 129 can be used for a NATO standard 70 mm rockets, initially with a Mk 40 rockets, but there have been larger and more advanced Mk a 6670 instead. Although the 70 mm rocket weapons in favor of NATO countries are compatible. But the Italian Army Aviation has also developed and equipped with a more uncontrolled fire caliber rocket system, the SNIA BPD81 mm banshee. Banshee rocket system parameter input digital integrated weapons management system (IAMS), a 129 A of the system into the existing IMS system, allowing the Rockets to select a different bullet and calculate emission, ignition time, and can make the rocket under the laser ranging and optical sighting system prompts launch. Italy's 81-millimeter rockets with a variety of warhead: high-explosive warhead (7 kg), pre-fragmentation warhead (7 kg), target (with a phosphorus combustion products) warhead, high explosive anti-tank warhead anti-tank / anti-personnel mine warhead PIP (10 kg, including 11 parachute stability of the sub-munitions) and training bombs. Typically, mongoose 8l mm rocket carrying two pods, each pod contains 12 rockets. When using the basic 7 kg warhead, the non-control rocket range of the fire 12 kilometers. Italian pilot launch rocket for a very precise line, even in the case of these long-range rockets can hit targets more precisely, to show off here almost become its largest capital. Performance is much higher than 81 mm 70 mm rocket rocket system. However, only 38 of its maximum load (mixed carrying 12 loaded pod and pod mounted 7), while the 70 mm rocket carrying the maximum amount of 76. A project development when the design of a 129 the occasion of the commencement of the Italian request for attack helicopters have also changed. Due to financial reasons, the Italian army helicopter gunships recognized
A129
as a 129 A single anti-tank should be a platform for helicopter reconnaissance missions by other (eg A109) to complete, and a complete about 100 A-129 fleet is also too large. In 1981, the Italian Army of anti-tank / reconnaissance helicopters, the military needs to determine the last modification. In the same year in December, A a pre-129 project received official funding. A 129 required for a number of advanced systems (including avionics, forward-looking infrared, etc.) started in A-109 test platform for initial testing. 1982 to 1983, the company created an Agusta 129 A full-scale fuselage of a model, mainly for the installation of IMS electronic equipment, and testing. March 1983, the military signed an agreement with the manufacturers, the agreement requiring manufacturers to test fly the prototype and the specific issues. August 1983, mongoose September 15, 1983, A prototype of a 129 (P1, No. 901),
air force 1 shoes, Virginia Costa, Casey was in the first official flight. It had been set up in September 11 and 13, conducted two simple flight. P1 is not installed on the production of avionics, the main driving force for the load and performance testing. The second prototype aircraft for the flight test P2 (manufactured by Agusta A third body, number 903) on 26 July 1984 made its maiden voyage, and take the strength and part of the flight performance tests carried out have since the power and airborne testing of the system. In 1984, the first static test of 902 for the machine were modified for flight testing of aircraft. The third prototype aircraft true (904) on May 23, 1985 the sky. The first aircraft equipped with the IMS system, mainly for electronic and weapons systems tests. July 18, 1986, the first four prototypes (P4, 905 number) joined the test team, the aircraft is also equipped with IMS and weapons systems. The first firing test at the October 1986 between the weapons test site in Sardinia, when the concept of using the M65 TOW missile aiming system and. The test results is very good, in December 1987 signed a military agreement with the vendor to purchase 15 A-129 anti-tank type and logistics support system (maintenance, spare parts and documents.) The aircraft is called In 1987, with the concept of using the new aiming system, the Mongoose with a night combat capability. As noted above, Saab HeHTOW improved is selected. In 1988, when being evaluated, in order to determine pottery, 81-mm rockets and Q-type HeliTOW day view of the operation aiming device distance Mongoose began its second and third live-fire test. In 1989, the military and sign a contract manufacturer to determine the day and night weapons systems. In the same year, mongoose were the fourth and fifth live fire tests, this included a 129 A for all weapons (Tao, 8l-mm and 70 mm rockets) and tested a new type of laser rangefinder HeliTOW system . Finally, in 1990, the sixth and final test increased firepower IIA launch of a Tao. The missile uses an improved warhead serial, can effectively deal with explosive reactive armor of tanks. October 6, 1990, the first five Mongoose Italian Army Aviation Training Centre to deliver the helicopter, Army aviation has its own model number, that
A129 helicopters
EA-l (EA is the Italian attack helicopter prefix abbreviation), but rarely used. When the first 129 A of a delivery coincided with the 39 anniversary of the establishment of the Italian Army Aviation, many officials attended the delivery ceremony, including Italy's new president, defense minister and commander of Army aviation. Italian Army Aviation is headquartered in Viterbo north of Rome, the Italian Army Aviation Training Centre is located in the city, Viterbo is also the headquarters of Army Aviation, which is directly under the army headquarters in Verona. Italian Army Aviation Command has 7 Aviation Regiment, one of which is the mongoose group. The front mongoose units REA (attack helicopter regiment) of a bright double star). Two operational units under the jurisdiction of the regiment, 48 and 49 attack helicopter squadron. The two units are land formerly filthy five groups 49 and 44 attack helicopter squadron. When the mongoose in 1992 when production temporarily, to the Italian Agusta company has delivered 45 Army basic type (including the A-129 type of development despite international / ~ -129 in the previous operations performed well, but in fact only the first 45 Italian airmen basic model equipped with a mongoose. The lack of funding have restricted the development of the key factors mongoose. To change this situation, must be mongoose to the international market. By Agusta findings of the Gulf War, the future needs of the international market must be the implementation of the armed helicopter escort, reconnaissance, anti-tank and close air support and many other tasks. This requires a helicopter equipped with a variety of weapons to adapt to different task environments. To be able to occupy a place in the international market, the company began improving Agusta, launched a 129 International Type A mongoose.
A129 helicopters
Previously, Agusta 902 aircraft test using a lot of new concepts. The most important of these tests is equipped with T800 engines and equipment under the gun in the nose. International-type will be equipped with two mongoose 1362 shaft horsepower rated (1016 kW) LHTEC CTS800-2 turboshaft engine, transmission output power increased to 1700 hp (1268 kW). A new type of air filtration devices are developed, the aircraft can also install infrared suppressor. The basic task of the international-type total weight of 4,800 kg, the maximum weight of 5100 kg tasks, increasing the fuel the body, extending battery life. International-type setting for the first time mongoose new engine test installation took 9 months time. In 1992, the aircraft installed in a single tube Lucas 12.7 mm machine gun, it mounted on the aircraft, Rely on new engine and machine guns installed an A-129 helicopters, Agusta in 1994, entered the export market, and exports to the Netherlands the second attempt, but ultimately chose the Netherlands for a 64 AH. 1993 to 1994 because of funding problems Agusta entered the most difficult period, December 1996, its ownership by the state-owned companies into private companies EFIM. In the same period, the Italian Defense Minister announced that the Italian Army aviation a 129 A-project funding cuts to the Army Aviation will slow the speed of delivery of mongoose. This series of tragedies prevented Agusta to sell to the UK and the Netherlands plan. Lesson to be learned from the shopping malls and the battlefield after the Agusta comeback, January 9, 1995, the final version of A-type prototype of a 129 international flight. The characteristics of the international-type mongoose, compared with the early prototypes, Use of main rotor Agusta mature, and the patent has been tested all hinged design, with five elastic shaft and composite blades. Late 1996, the status of 902 instead of the second plane was --I-INTR/800. This organism was originally manufactured for the Italian Army for the unfinished one in the third batch of aircraft, Agusta company number 29052. It begins with the engine and equipped with the T800 replaced in early 1997 a new type of rotor. So it can be called a true sense of the first frame of the International-type with the Italian Army original mongoose different models also include improved SRTl70M6 and SRT65IN radio stations and a new crew intercom. New navigation system uses the Litton LN 1002G inertial / GPS navigation device mode. Added new ANV353 helicopter Doppler velocity sensor, in addition to Alenia's 24MWl001 radio altimeter. Air data system upgrades for the General Electric Company, Marconi Avionics Corporation HADSl553B.

cockpit cockpit international-type changes are obvious. Each crew will install both the dashboard Alenia's 6 × 8 英寸 (15 x 20 cm) color flat panel displays, including a mobile digital map. Alenia is also developing a new central computer language based on ADA, or 060 using the Motorola 68040 processor. As well as the display for the next display processor, in addition to the development of a mongoose and image data modem. Widely installed in the cockpit of the straight optical observation systems will be replaced by a CCD TV camera (in order to work in the near infrared region used in low light conditions.) A new helicopter combines the use of the autopilot control system, allowing off pole attack. Binocular integrated helmet display system also is under development, the system has the ability to fly low altitude night-round. Pilots will also receive ANVIS-6 goggles to prevent laser damage. As the red appearance of the aiming system before the Agusta 129 is an international model for the A to select a target line of attack, as the red appearance of the aiming system before, the system able to track the distance increased by 50% or more. A-l29 has been serving the original forward-looking infrared system is the design of 8 to 12 microns, which is to choose the best night to use the wavelength, but this wavelength, the larger attenuation in the air. However, with thermal imaging technology, 3-5-micron wavelength FLIR systems have been more suitable for high humidity environment, Australia and New Zealand for his Siren helicopter chosen such a system. Fire control system for the international type of mongoose,
