air catapult

Abstract

The invention provides an air catapult, and relates to the technical field of booster instruments. The air catapult comprises supporting frames, an energy storage control device, sliding devices, an airflow regulation device and a power device, wherein the energy storage control device comprises a spring seat, a spring and a transmission rod; the spring seat is arranged on a supporting frame; the spring is connected with the spring seat; the spring is connected with the transmission rod; a traction tray is arranged at one end of the transmission rod; a nose landing gear of a fixed-wing aircraft is arranged on the traction tray; the airflow regulation device comprises an air cylinder, a supporting plate and a flow deflector; the air cylinder is arranged on the supporting frame; the flow deflector is hinged to the supporting frame; the air cylinder stretches the flow deflector to the maximum angle after takeoff of the fixed-wing aircraft, and the airflow generates opposite acting force, so that the device can brake rapidly; besides, auxiliary power is provided for an aircraft carrier; according to the air catapult disclosed by the invention, a deck does not need to be transformed, so that costs are reduced; the air catapult can also be used in an airport; and when an airport runway is damaged and a new runway cannot be arranged in time, the aircraft can be guided for short-range acceleration take-off by the air catapult, so that the airline can operate normally.

Description

technical field [0001] The invention relates to the technical field of booster devices, in particular to an air catapult. Background technique [0002] Existing catapults include steam catapults and electromagnetic catapults. The structure of steam catapults is complex. To take off and land an aircraft, it must be against the wind. When taking off and landing a carrier-borne heavy fighter, such as the Su-33, the sliding distance is longer than that of the catapult Many, and it cannot take off normally when the weather conditions are poor. The structure of the steam catapult is complex and heavy, and the cost of manufacturing is relatively high. When the electromagnetic catapult is manufactured, it needs to bury the track on the deck of the aircraft carrier, and the cost is high. , insufficient energy, when the weight of the fixed-wing aircraft is large, it cannot meet the flight needs. Contents of the invention [0003] The object of the present invention is to provide a ...
