Gong, the chief designer of Kitty Hawk -500, vividly described the plane he designed as an "air car". Indeed, if the wing and tail are ignored, Kitty Hawk -500 is more like a private car. The basic type of Kitty Hawk -500 aircraft is trainer, and it can also be equipped with autopilot, multi-function display and other equipment according to the needs of users. After being converted into fixed landing gear, the telescopic landing gear can be used as a private business jet or other aircraft. Kitty Hawk -500 aircraft has a wide range of uses, which can be used for pilot training, private official flight, tourist aircraft, agriculture, forestry, animal husbandry and fishery and environmental protection aircraft, as well as aviation exploration, aerial photography, aviation club and air force naval flight teaching and training, official duties, air patrol and so on, with strong applicability.
"Kitty Hawk" -500 aircraft has widely adopted the advanced technology, technology and new materials of modern aviation industry in its design and manufacture, making the aircraft reach the advanced level of similar products in the world. For example, the manufacturing technology of thin skin and large partition frame used in aircraft is adopted for the first time in China aviation manufacturing industry. The fuselage of the aircraft is semi-rigid aluminum alloy structure, the side skins of the nose, tail cone and cockpit are made of FRP, and there are two aluminum alloy ventral fins vertically downward in the abdomen of the fuselage. The aircraft wing adopts cantilever lower wing and the structure is aluminum alloy single beam. What is different is that the wing tip of Kitty Hawk -500 is upturned with FRP, which can improve the flow around the wing tip and reduce the induced drag of the aircraft. The tail of the aircraft adopts a fully moving rectangular horizontal tail with equal cross section, and the left and right wings are integrally installed on the upper part of the tail cone of the fuselage. Both the horizontal tail and the vertical tail are riveted with aluminum alloy, and both the rudder and the horizontal tail are equipped with adjusting pieces.
Kitty Hawk -500 is designed and manufactured in strict accordance with CCAR-23-R2 airworthiness regulations of China Civil Aviation Department. As Mr. Gong said, Kitty Hawk -500 is light (empty weight is 840 kg), but the sparrow is small and complete, and the major systems of the aircraft, such as fuel system, environmental control system, hydraulic control system and power system, are all complete. After testing, it has been proved that Kitty Hawk -500 is a complete aircraft. In order to ensure the stability of aircraft take-off and landing, the aircraft landing gear adopts retractable front three-point landing gear, and the main landing gear is a space rotating shaft rocker arm type. In order to reduce the vibration when landing as much as possible, the nose landing gear and main landing gear of the aircraft are equipped with oil-gas shock absorbers, and the main wheel of the aircraft is also equipped with single-disc brakes and emergency equipment.
The main advantage of Kitty Hawk -500 in market competition is economy, which is mainly reflected in the price and efficiency ratio of aircraft. The price of this plane will be around RMB 2 million after it is put into the market, which is almost the same as that of a high-end car imported from abroad. The fuel consumption of this plane is about 40 liters per hour, while the fuel consumption of a fuel-efficient car is about 65,438+00 liters per 100 kilometers. In terms of efficiency ratio, Kitty Hawk -500 is not inferior to cars at all, while the fuel consumption of a jet light and small general-purpose aircraft is about several hundred liters per hour, which is the main reason why the piston general-purpose aircraft has not been eliminated for a long time, and Kitty Hawk -500 aircraft uses piston engines as power. It is the main guiding ideology for the development of Kitty Hawk -500 aircraft to actively adopt internationally mature technologies and processes, reduce development costs and minimize development risks. The power plant of this machine is the horizontally opposed 6-cylinder air-cooled piston engine of Lycoming Company of the United States. The company mainly produces all kinds of aero engines and has a good reputation. It is said that the engine produced by the company has not stopped in the air so far. The cockpit of the plane is a closed non-airtight cockpit with two rows of seats. The two seats in the front row can adjust the sitting posture and are equipped with inertia drum seat belts, and the benches in the back row are equipped with ordinary seat belts.
The operation of the aircraft is a single drive system, but it is equipped with two sets of control systems. There is an upward gate on both sides of the fuselage, and there is an emergency window behind the gate. It is worth mentioning that "Kitty Hawk" -500 installed an air-conditioning system in order to increase comfort, which is a weight-reducing system rarely used by foreign general-purpose aircraft. The standard airborne equipment of this aircraft includes airspeed indicator, altimeter, vertical speedometer, gyro horizon, magnetic compass and stall warning device. In addition, the aircraft also uses a large number of advanced airborne equipment, which enables it to take off and land at large airports, which makes the Kitty Hawk -500 aircraft have many capabilities that similar aircraft do not have.
Kitty Hawk -500 is scheduled to complete the airworthiness verification test flight and obtain the type certificate (TC) in the first half of 2004, obtain the production license in the second half, and deliver the first batch of commercial aircraft to users. At the same time, as China Civil Aviation signed a bilateral mutual recognition agreement with the FAA of the United States, Kitty Hawk -500 is expected to gain overseas airworthiness recognition as soon as possible after passing the domestic airworthiness review and completing certain working procedures, so as to fly abroad to participate in the international market competition.
