China's Zhi -9 helicopter gunship, the localization progress of Zhi -9 is almost synchronous with the introduction: in the 1980s, while using French parts to produce Zhi -9, it began to gradually realize the localization of the whole helicopter on the basis of digesting and absorbing imported technology. 1in may, 988, zhi -9 localization headquarters signed a contract with relevant departments. Harbin Aircraft Manufacturing Company is the general contractor. It took more than three years to tackle key problems with more than 90 other factories and finally made a major breakthrough. 199265438+1October 16 localized Zhi -9 (localization rate reached 7 1.9%) successfully made its first flight in Hafei.
Power plant:
Two "AAGJE"1C free turboshaft engines (domestic "Zhi -9" is "8 A turboshaft"), with a single power of 525 kW (7 10 shaft horsepower).
Size data:
Rotor diameter 1 1.93m, tail rotor diameter 0.90m, captain 13.64m, fuselage length1.44m, and aircraft height 3.47m ..
Weight data:
Empty weight 1975 kg, maximum takeoff weight 3850 kg, payload 1863 kg, maximum suspension load 1600 kg.
Performance data: (gross weight 3,850kg) Maximum horizontal flight speed 306km/h, maximum cruising speed 285km/h, economic cruising speed 250-260km/h, oblique climbing rate 7.7m/s, vertical climbing rate 4.2m/s, upper limit 2,200m, hovering height (with ground effect and standard atmosphere) 2.
Model development:
Zhi -9 carrier aircraft type. The nose radar is installed, which can mount two "Yu -7" torpedoes. Other specific data are unknown.
Zhi -9G armed helicopter has strengthened its armor protection, and can mount "Red Arrow -8" anti-tank missiles, rockets (57- 1, 90- 1) and machine guns. It is used for anti-tank operations at the front of the battlefield, suppressing ground fire, raiding ground scattered targets and other fire support tasks. It can also be used for tasks such as transportation, troop mobility, helicopter air combat, communication and ambulance. The aircraft made its first flight in June 1988+00, passed the design approval in February/995, and was approved in May/996.
China's development of this type of armed helicopter is obviously to make up for the serious shortage of the Army's armed anti-tank helicopter. Including installing a rocket launcher on the imported Mi-17. Before the special armed helicopter was put into use, there was a lot of space in the middle. There is no doubt that this is also a stopgap measure. It is believed that with the development of helicopter technology in China, a more advanced special armed helicopter ("Wuzhi-10") will appear in front of us.
Z-9 helicopter is a dual-engine light multi-purpose helicopter developed and produced by Harbin Aircraft Manufacturing Company of China, and the patent of French SA-365N Dauphin)2 was introduced. /kloc-0 officially introduced the patented production in June, 1980.1in June, 1982, the first Z-9 helicopter was assembled and rolled off the assembly line.
The rotor system of Z-9 consists of four composite blades and a star-shaped flexible rotor hub. Its tail rotor is a ducted fan tail rotor, which consists of the hub and 13 die forged light alloy blades. Another major feature of Z-9 is that there are flat tails on both sides of the tail beam and vertical end plates at both ends of the flat tail, which can change the flight performance of the aircraft. The Z-9 landing gear is the first retractable three-point dual-chamber hydro-pneumatic shock-absorbing wheeled landing gear, and its power unit is two Aagje 1C turboshaft engines from Toubomeca, each with a power of 522 dry watts. Z-9 has a wide range of uses, which can be used for personnel transportation, offshore support, maritime rescue, patrol, aerial photography, fish observation, forest protection and fire prevention, and can also be used as a carrier aircraft. In addition, Z-9 can also be modified into anti-tank, maritime search and rescue, anti-submarine, reconnaissance artillery and communication.
Starting from 1988, China began to implement the localization of Zhi -9. 199265438+1October 16, the first domestic Zhi -9 (Z-9A- 100) flew into the blue sky, and then successfully completed various flight test subjects. At the end of 1992, the technical appraisal meeting of Z-9 domestic complete machine showed that the localization rate of Z-9 had reached 72% and it could be put into mass production. At present, there are three models of Z-9: Z-9, the original patented production type,150 ordered by the end of 990, all of which have been produced; The models that continue to be produced after Z-9A and Z-9 are equivalent to SA-365N1; Z-9A- 100, domestic Z-9, is also the current mass production type. The following data applies to the Z-9 prototype.
Dimension data: rotor diameter 1 1.93m, tail rotor diameter 0.90m, captain 13.46m, machine height (rotor and tail rotor folded) 3.2 1m, main wheel track 2.03m, front and rear wheel track 3.6/kloc-.
Weight data: empty weight 1975 kg, payload 1863 g, maximum takeoff weight 4000 g, maximum hanging weight1600 g.
Performance data: the maximum horizontal flight speed is 324 km/h, the cruising speed is 250-260 km/h, the maximum climb rate (sea level) is 4.2 m/s, the service ceiling is 6000 m, the hovering height is 1950 m when there is ground effect, 1020 m when there is no ground effect, and the maximum range is/.
