193 1 was there a helicopter in China?

193 1 There are no helicopters in China.

1938, Hannah Reich, a German girl, performed a perfect flight show in Berlin Stadium with a twin-rotor helicopter. This helicopter is considered by the helicopter industry to be the first successful helicopter in the world.

1939 Spring, Igor, USA? Sikorsky completed all the design work of VS-300 helicopter and built a prototype in the summer of the same year. This is a single-rotor helicopter with a tail rotor. Equipped with a three-blade rotor with a diameter of 8.5m and a Shuang Ye tail rotor. Its fuselage is welded steel pipe structure, and the transmission device consists of V belt and gear. The landing gear is rear three-point, and the cockpit is fully open. The power plant is an air-cooled engine with four cylinders and 75 horsepower. This single-rotor helicopter configuration with tail rotor has become the most common helicopter configuration at present.

1939, American Sikorse invented the first helicopter. The fuselage shape is not much different from now, and it is still adopted by designers.

Development of helicopters in China

1 .straight 5

Zhi -5 is the first multi-purpose helicopter made in China, and it is also the beginning of scientific research and application of new China helicopter.

The initial development code was "Cyclone 25", and the prototype was the Soviet Mi -4 helicopter.

1958 in February, Harbin Aircraft Industry Company began to copy Mi -4, 1958, 14 in February, and 1959 in early June officially passed the acceptance of the National Appraisal Committee and put into mass production. 1September 2, 9631day, the Navigation Committee agreed that the Zhi -5 helicopter would pass customs clearance with high quality and was allowed to finalize the design and put into production. Its power plant, Piston -7, passed the quality inspection on February 25th of the same year and was put into mass production. A total of 545 aircraft were produced.

Zhi -5 can be used for material and personnel transportation, life-saving and border patrol. 1980 discontinued.

Zhi -5 adopts 1 Piston -7 air-cooled star 14 cylinder engine with power 1770 HP (1250 kW). The main propeller has a diameter of 2 1m, a length of 16.8m and a height of 4.4m. The landing gear is fixed at four points, with front landing gear side tread 1.53m, main landing gear 3.82m and front main tread 3.79m. Engine room volume16m3, side hatch, clamshell rear hatch. It can carry 1 1 fully armed soldiers, or 8 wounded stretchers, 1 medical staff at a time. The engine room is located at the nose and drives the main rotor at the top of the engine room and the tail rotor at the tail through the transmission shaft. The cockpit is located in the front upper part of the nose, with two crew members, both of whom can independently complete flight control. It can carry 1.2 tons of goods, and can carry 1.35 tons when lifting. Jing 2 12A Jeep can be loaded and unloaded in the straight -5 engine room, and is often used as a carrier of the 78-type 82mm recoilless gun to provide fire support for airborne troops. More powerful is the 75 105mm recoilless gun, developed in 1964, which can destroy main battle tanks, armored vehicles and solid field fortifications. , and designed and finalized in 1975. A gun consists of a gun body and a gun rack. The principle of high and low pressure launching and the method of combining muzzle brake with contraction nozzle are adopted. It is still carried by Jing -2 12A light off-road vehicle. The initial velocity (armor-piercing projectile) is 503 m/s, the maximum range (explosive Grenade) is 7400 m, and the effective range (armor-piercing projectile)1/00m; The direct distance (armor-piercing projectile) is 580 meters, the firing rate is 5 ~ 6 rounds per minute, and the gun body is 3409 mm long. The tail rotor is made of three pressed FRP blades, and the cockpit is located in the front upper cabin of the fuselage with two seats. The landing gear is 4 wheels; Power plant: 1 air-cooled 14 cylinder with 7 engines, maximum power 1250 kW (1700 horsepower).

2. Straight 6(Z-6)

Zhi -6 is a multi-purpose helicopter modified from Zhi -5. It made its first flight in February 0969+65438+June 05, with a total production of 15, but it was not officially put into production, so it will not be introduced in detail here.

3. Straight 7(Z-7)

In the mid-1960s, while developing light and medium-sized helicopter products, China also began to consider developing its own heavy helicopter products, which can carry a reinforced platoon. According to the demand put forward by the army, 1969, China Aviation Research Institute decided that the newly established helicopter design institute should undertake the design task of heavy helicopters, and the helicopter number was Zhi 7. 1in March, 970, the research and development work of Zhi 7 began, and five research institutes and two factories, including Helicopter Design and Research Institute, undertook the research and development work.

The development scheme of Zhi 7 is as follows: two turboshaft 5A engines with six rotors are installed; In addition to redesigning the hub and reducer, other parts should adopt straight 5 and straight 6 as far as possible. Zhi 7 has a designed maximum takeoff weight 14400kg, an effective commercial load of 3,500kg, a maximum speed of 240km/h, a maximum range of 35O km, and a service ceiling of 6,000m m.

On June 7th, 2008 +097 1 started the static testing and debugging of the engine block and components. At the same time, the leading organ has decided to use Zhi 7 as the testing machine for ship-borne helicopters. By September of 197l, the work of changing Zhi 7 into a ship-borne helicopter stopped and continued to be developed as an ordinary helicopter.

1May, 975, 7.97% of the parts were processed and assembled into two airframes, and 90% of the finished products were delivered. 1979, Zhi 7 heavy helicopter completed the whole static test.

However, on June 28th, 1979, the state decided to stop the development of Zhi -7 heavy helicopter. The reason is that the national financial resources are limited, and it is impossible to invest in the development of two heavy helicopters at the same time. In order to fully ensure that Jiangxi Jingdezhen Helicopter Factory undertakes the development of Zhi -8 helicopter project, Zhi -7 helicopter had to give way to Zhi -8, thus declaring the death of Zhi -7 heavy helicopter. Although the Zhi -7 project was abandoned, many achievements in the development of Zhi -7 laid a solid foundation for the successful development of Zhi -8 heavy helicopter with the maximum takeoff weight of 13000 kg.

4. Straight 8(Z-8)

At the end of 1970s, China purchased 14sa 3, 2 1 "Super Hornet" large multi-purpose helicopters developed by the French Aerospace Industry Corporation, and handed them over to the naval aviation. The aircraft was delivered in France on 1966, and became the first generation carrier aircraft in China after being equipped. Subsequently, China began to imitate Zhi -8 on the basis of "Super Hornet".

The research work of Zhi -8 is jointly carried out by China Helicopter Research and Development Institute and Changhe Aircraft Industry Company. The overall plan is to take the Zhi -8 shipborne anti-submarine model as a breakthrough, introduce imitation, and then improve the development of Zhi -8 army model, so as to gradually improve the scientific research, production and equipment level of large and medium-sized helicopters in China. R&D started at 1976. The first prototype made its first flight in1985+February,1989+065438+1October passed the national technical appraisal, and1994+February was designed and finalized. 1989, the first production Zhi -8 was delivered to the naval air force.

At the end of 1970s, China purchased 14sa 3, 2 1 "Super Hornet" large multi-purpose helicopters developed by the French Aerospace Industry Corporation, and handed them over to the naval aviation. The aircraft was delivered in France on 1966, and became the first generation carrier aircraft in China after being equipped. Subsequently, China began to imitate Zhi -8 on the basis of "Super Hornet".

As early as the mid-1960s, while developing light and medium-sized helicopter products, China has begun to consider developing heavy helicopters capable of loading platoon units. 1969 China aviation research institute decided that the newly established helicopter design institute should undertake the design task of heavy-duty helicopter, the model of which is Zhi -7. The development scheme is as follows: 2 turboshaft -5 A engines are installed and 6 rotors are used; Except for the redesign of the hub and reducer, other parts are straight -5 and straight -6. Zhi -7 has a designed maximum takeoff weight14,400kg, an effective commercial load of 3,500kg, a maximum speed of 240km/h, a maximum range of 35km and a service ceiling of 6,000m. 197 1 nianzhi -7 began the static test and debugging of the engine block and components. In the meantime, it was once decided to use Zhi -7 as a ship-borne helicopter. 1May, 975, 97% of the parts of Zhi-7 were processed and assembled into two airframes, and 90% of the finished products were delivered. 1979 straight -7 to complete the static test of the whole machine. 1On June 28th, 979, it was decided to stop the development of Zhi -7. It is said that the reason is that the country's financial resources are limited, and it is impossible to study the Zhi -7 and financially ensure that Jingdezhen Helicopter Factory imitates the Zhi -8 helicopter project. So Zhi -7 was forced to death, but many achievements laid the foundation for the development of Zhi -8.

The research work of Zhi -8 is jointly carried out by China Helicopter Research and Development Institute and Changhe Aircraft Industry Company. R&D started at 1976. The first prototype made its first flight in1985+February,1989+065438+1October passed the national technical appraisal, and1994+February was designed and finalized. 1989, the first production Zhi -8 was delivered to the naval air force. Although the Zhi -8 has already entered the mass production state, its output is very small, estimated to be only 15. Zhi -8 was once regarded as a big leap for China Luhang and Hainan Airlines, because it was the first domestic large and medium-sized multi-purpose helicopter. I don't want to be a chicken rib in the long years before 2002, when the output of Zhi -8 was very low, no more than 20.

Zhi -8 adopts the general layout of conventional helicopter, with single rotor with tail rotor. The rotor consists of six rectangular bonded all-metal blades, and the hub is hinged, equipped with flapping hinge, axial hinge and swing hinge with hydraulic damping. There are five tail rotors at the top of the tail wing. In order to adapt to the use on water, the boat-shaped fuselage, watertight cabin and amphibious short-wing buoys fixed on both sides can be used for taking off and landing on water. Non-retractable front three-point landing gear is used on land. Zhi -8 uses three turboshaft -6 engines, two in front of the reducer and one in the back. The maximum takeoff power of a single engine is 1 128 kw (1550 hp). The main oil tank in the machine consists of three groups of eight soft oil tanks, with a total effective volume of 3900 liters. The fuel tanks and related cabins are equipped with ventilation systems, and each group of fuel tanks has a gravity refueling port located on the left side of the fuselage.

Zhi -8 can carry 27 fully armed soldiers. At this time, the voyage is 700 kilometers, and it can carry 39 people under the maximum load. It can also carry a BJ-22 jeep and related personnel; Either fly 500 kilometers with 3000 kilograms of goods, or transport 5000 kilograms of goods to the target area 50 kilometers away and then return to the original place. When used for rescue, Zhi -8 engine room can carry 15 patients, stretchers and a medical staff. When performing search and rescue, the aircraft can be equipped with a hydraulic rescue winch and two lifeboats to perform rescue tasks on land and at sea.

In fact, the purpose of China's imitation of Zhi -8 is not to use it on land, but to obtain a reliable ship-borne helicopter. Therefore, Zhi -8 quickly developed a carrier-based model. Zhi -8 can be equipped with suspended sonar and search radar, and the weapons that can be used include torpedoes or missiles. When carrying out mine-clearing tasks, you can drag mine-clearing tools in the waters 92 kilometers away from the base and mine for two hours at a speed of 46 kilometers per hour. When laying mines, you can carry eight 250kg mines. The figure below shows the floating test of the prototype.

The navy model Zhi -8 has participated in actual combat missions for many times.

Zhi -8 also developed the Army-type Zhi -8A.

Zhi -8 can also be used for civil purposes such as personnel transportation, geological exploration, aerial mapping, building construction, forest fire prevention, border patrol, communication and command. Zhi -8 has successfully carried out rescue and disaster relief, scientific research flight test and other tasks, and successfully made its first flight to Xisha on 1993.

The reason for the low output of Zhi -8 is not disclosed. It is estimated that the biggest possibility is that the imitation performance is not good, or the core components, such as engines, cannot be produced by themselves. Judging from the massive purchase of Mi-17 by Luhang Airlines, Zhi -8 has no position in the army. HNA is equipped with Zhi -9. Perhaps this kind of light helicopter is urgently needed by small tonnage naval vessels. The performance of the prototype SA32 1 of Zhi -8 is actually good, and it is the main force of the French army. We have worked hard to copy, but we can't solve the problem of localization of core components.

In May, 2002, foreign news reported that China planned to resume the production of Zhi -8, and would adopt PT6 series engines of Canadian Pratt & Whitney Company, and then introduce its engine production technology. It is reported that Changhe Company had manufactured 17 aircraft before it stopped production of Zhi -8 in 1997, among which 12 aircraft is currently in service in the navy. If the report is true, it shows that the military still hopes to have its own large helicopter. In addition, it is also confirmed that the engine of Zhi -8 cannot be developed by itself.

The so-called "another village with a bright future", the appearance of Zhi -8F at the 2002 air show, announced the arrival of Zhi-8F. Model F is the latest modification of Zhi -8A, and it is equipped with an imported PT6B-67A engine (PT-6B in the picture below). The maximum takeoff power is increased from 1 190 kW to 1448 kW, the ceiling is increased to 4700 m, and the effective hovering is increased from 1900 m to 2800 m..F The F engine can be started at a plateau of 4,500 m, and the first engine rotation period is greatly increased to 3,500 hours. The anti-sand device was added to the air inlet to improve the field performance, so the shape of the fuselage above the cockpit changed. Using composite blades with anti-icing and deicing ability to replace the original metal blades improves the life efficiency and performance of the suspended wing and refits it into a new avionics system. The F-type is still in the development stage, and it is planned to be put on the market in 2005, which is expected to equip the PLA in large quantities. However, PT6 series engines must be localized.

5. Straight 9(Z-9)

Zhi -9 light multipurpose helicopter was developed and produced by Harbin Aircraft Manufacturing Company with the introduction of French patents. It can be used for personnel transportation, maritime support, maritime rescue, aerial photography, maritime patrol, fish observation, forest protection and fire prevention, etc. , and can be used as carrier aircraft. Military applications include reconnaissance, close fire support, anti-tank, search and rescue, anti-submarine, reconnaissance and artillery correction, and communication.

1980 10 the State Council approved the contract for exclusive production of French SA365 dolphin helicopter in the form of technology and trade. Hafei was specifically responsible for introducing the French patent of SA365N 1 "Dolphin" helicopter, and began to produce Zhi -9, 1982, and completed the assembly of the first helicopter. On February 6th of the same year, the Zhi -9 60 13 aircraft performed a test flight at the Capital Airport, with the participation of responsible comrades from the PLA headquarters, various arms and services and ministries. On September 2 1, two Zhi-9s were delivered to China Civil Aviation Guangzhou Administration for the first time and put into use. After long-term efforts, Hafei has developed several models, including the basic Zhi -9, which was originally patented. By the end of 1990, all 50 aircraft contracted with France had been produced, including 28 basic straight-9 aircraft; In addition, there are 20 Zhi -9A, which will continue to be produced after Zhi -9, equivalent to SA365N2；; Subsequently, Hafei produced two Zhi -9A- 100, and initially tried the domestic production of Zhi -9. 1September 1993, Hafei signed a contract with France to produce 22 Zhi -9 transitional batches, and Hafei also produced 8 Zhi -9 civilian models.

1in may, 1988, zhi 9 localization headquarters signed a contract with relevant departments, among which Harbin aircraft manufacturing company was the general contractor. After more than three years, together with more than 90 other factories, the localization of Zhi -9 was successfully completed on June 1992 (the localization rate reached 765438). After that, the production of Zhi -9 turned to domestic Zhi -9, named Zhi -9B.

Zhi -9 adopts the tail rotor layout of ordinary rotor with ducted fan. Its rotor system consists of four composite blades and a star-shaped flexible rotor hub. The tail rotor of ducted fan consists of a hub and 13 die forged light alloy blades. Both rotor blades and tail rotor blades have infinite life. Flat tails are installed on both sides of the tail beam, and vertical end plates are installed at both ends of the flat tail to improve the stability of the flight direction. The landing gear is retractable front three-point wheeled landing gear. The nose landing gear is two-wheeled, automatically oriented, and enters the fuselage backwards. The main landing gear is a single wheel, which is retracted inside the fuselage. The landing gear has a double-cavity oil-gas shock absorber.

Ducted tail rotor is a major feature of dolphin helicopter, which has the advantages of small tail rotor space, high aerodynamic efficiency, and the tail rotor is not easy to be injured by foreign objects. Moreover, due to the small air resistance of the ducted tail rotor, the speed of "Dolphin" is faster than that of ordinary helicopters. In fact, Dolphin is the fastest helicopter in mass production at present. The disadvantages of ducted tail rotor are that it is heavier than the traditional common tail rotor, complicated in structure and cumbersome in maintenance.

The power plant of Zhi -9 adopts two turboshaft engines of "AAGJE"1C from Tubomeka Company, with a single power of 522kW. The domestic Zhi -9 is a turboshaft engine with turboshaft -8A (domestic model of turboshaft -8A, Aagje 1C). The maximum emergency power of a single machine is 734 axis horsepower, and the takeoff power is 7 10 axis horsepower. It can fly with a single engine at maximum flying weight. The main airborne equipment on board includes VHF and HF communication/navigation equipment, VHF omni-directional beacon, instrument landing system, radio compass, transponder, ranging equipment, radar and autonomous navigation system. Optional equipment includes load-bearing 1700 kg sling and load-bearing 275 kg winch. The winch cable is 90 meters or 74 meters long. BG-0.6 radio altimeter, 150 single sideband radio, KJ- 13 autopilot, 40AH battery and 400-liter transit fuel tank can be installed on the airborne equipment of Zhi -9B. Imported equipment such as KDF-806 radio compass, KTR-908 radio station, TB-3 1 internal communication equipment, electric winch, plug-in with dynamometer and reflector, searchlight, etc.

According to the needs of PLA Army and Naval Air Force, several military improvements have been derived from Zhi -9: Zhi -9A (domestic type), Zhi -9B (troops stationed in Hong Kong, the same below), Zhi -9 communication type, Zhi -9 artillery calibration type, Zhi -9 electronic jamming type, Zhi -9C shipborne type, Zhi -9W anti-tank type and Zhi -9G. Zhi -9G is a W-type export type, and its electronic equipment is different.

The carrier type of Zhi -9C is actually improved on the basis of Zhi -9, which has little to do with the carrier type of French Dolphin Leopard. On February 2, 65438 and 87, the first flight of the Zhi -9C ship-borne helicopter modified for the navy was successful. 65438+ successfully landed on February 24th, using the fast landing mooring device designed and developed by China Helicopter. The finalized type C is equipped with nose radar, which can mount two "Yu -7" torpedoes to perform anti-submarine missions. Yu -7 is an imitation of the American MK-46 torpedo captured by China fishermen on Hainan Island, and its performance is close to MK-46.

6. Wu Zhi 10(WZ- 10)

The direct 10 project is mainly undertaken by Harbin Aircraft Manufacturing Company (HAMC). 1992, guiding the establishment and development of more than 40 related research institutes nationwide. The key research projects of the "Five-Year Plan" have been paid attention to by the leaders of the General Assembly Department. Lieutenant General Xu Huaizhong, Vice Minister of General Assembly Department, visited the company for many times to inspect the progress of the project.

WZ- 10 is a medium-sized full-time armed helicopter developed from Z-9B, with a net weight of about 5543 kg. Its main task is to intercept the battlefield at the treetop height, destroy the effective forces including the enemy's fixed and mobile ground, and have certain air combat capability. In the future, WZ- 10 will cooperate with Z- 1 1 light helicopter with overhead sight to achieve the goal, which can completely attack the enemy's hiding place, so the battlefield survivability is extremely strong. In addition to some photoelectric aiming systems visible in WZ-9, this aircraft is also equipped with FLIR, so its ability to fight in complex weather and at night is limited.

The total length of the helicopter is about 14. 15 meters (when the rotor rotates), the height is about 3.84 meters, and the widest part (note: including short wings) is about 4.35 meters. Adopt the internationally popular tandem cockpit layout, narrow fuselage and rear three-point anti-collision landing gear. Basically inherited the Z-9 ducted tail rotor and flight transmission system. The main propeller consists of four fully composite blades, the diameter of which is about 12m, and the tail rotor is 1 1 elastic glass fiber wide blade. Compared with American RAH-66, the traditional WZ- 10 does not have the aerodynamic structure of radar stealth. Instead, a large number of composite materials and coatings that absorb radar wavelengths are used to shorten the distance discovered by the enemy and also achieve the purpose of reducing the weight of the aircraft. The power plant adopts two turboshaft engines (MTR390) produced by European MTR. The specific data is unknown, and it is estimated to be roughly the same as Italy A 129. Avionics equipment adopts domestic and statutory digital systems. The navigation system is three-axis gyro laser+radio altimeter+Doppler radar +GPS. There is a head-up display (HUD) and three multi-functional digital displays (MFD) in the cockpit. Combining with the mode switching control system of HOTAS (plus the pointer backup of some main flight instruments), the pilot's load is greatly reduced, so that the pilot can spend more time observing the surrounding geographical and tactical environment instead of dazzling various instruments. This is one of the greatest characteristics of contemporary battlefield tactics, and the sense of state of affairs is also the watershed of the first and second generation technology of Wuzhi!
