Gravity catapult-assisted take-off device for carrier-based aircraft

Abstract

The invention relates to a gravity catapult-assisted take-off device for a carrier-based aircraft, which belongs to the field of the manufacturing technology of aircraft carrier corollary equipment. The gravity catapult-assisted take-off device consists of a deck propulsion part, a water box lifting part and a water supply and drainage part, wherein the water box lifting part is connected with the deck propulsion part through a steel cable, and the water supply part forms a system independently. When the device is used, a winding engine is started, the steel cable is pulled and lifted to liftthe water box to a high position; a pushing slider moves backwards to a position of an electromagnetic latch; the electromagnetic latch is latched, a clutch of the winding engine is separated, and a water pump is started to fill up seawater in the water box; the aircraft is clamped on the pushing slider after the aircraft is in place on a deck; the electromagnetic latch is started to remove latching; the water box filled with the seawater falls off under the action of gravity; the pushing slider is driven by the catapult-assisted steel cable to move ahead at an accelerated speed and promote the aircraft to take off; after the water box falls on the sea surface, a box bottom is open, and the seawater is discharged; and the winding engine is restarted, the drained water box is pulled up, the seawater is filled in the water box to prepare for another take-off. The gravity catapult-assisted take-off device has the advantages of reasonable design, simple structure, convenient use and the like.

Description

technical field [0001] The invention relates to a gravity catapult take-off device for a carrier-based aircraft, which belongs to the technical field of aircraft carrier supporting equipment manufacturing. Background technique [0002] Currently, there are steam catapults for carrier-based aircraft that are in the practical stage, and electromagnetic catapults are being developed and implemented. Steam catapults need to be equipped with huge steam boilers and bulky pressure tanks to meet the needs of tens of meters long cylinders. Volume requirements, and the working characteristics of the steam catapult is that the steam pressure that pushes the piston is high at the beginning. With the movement of the piston and the expansion of the cylinder volume, the steam pressure decreases and the thrust decreases, which is exactly the opposite of the acceleration requirement for aircraft ejection and take-off. Electromagnetic catapults need to manufacture large-scale linear motor coi...

[0002] Currently, there are steam catapults for carrier-based aircraft that are in the practical stage, and electromagnetic catapults are being developed and implemented. Steam catapults need to be equipped with huge steam boilers and bulky pressure tanks to meet the needs of tens of meters long cylinders. Volume requirements, and the working characteristics of the steam catapult is that the steam pressure that pushes the piston is high at the beginning. With the movement of the piston and the expansion of the cylinder volume, the steam pressure decreases and the thrust decreases, which is exactly the opposite of the acceleration requirement for aircraft ejection and take-off. Electromagnetic catapults need to make large-scale linear motor coil windings, as well as huge power generators and energy storage power supply equipment, which are high in cost, complex in structure, and expensive in manufacturing and maintenance
