Two-way driving winding speedup type ship-borne aircraft catapult

Abstract

The invention provides a two-way driving winding speed type ship-borne aircraft catapult. Two ends of an ejection runway are provided with two speed changing winches, the winch arranged at the left end is a traction winch, and the winch at the right end is a return winch; and a traction strap runs through the ejection runway to be connected with strap spools on the two speed changing winches, and a sliding shuttle is arranged in the middle of the traction strap. The continuous winding of the traction strap on strap spool shafts of the traction winches results in the rapid increase of the diameter and synchronously tows the sliding shuttle to speed up from a low speed to a high speed on the ejection runway to realize that the sliding shuttle speeds up the ejection takeoff of a ship-borne aircraft from a low speed to a high speed; the speedup mode that the continuous winding of the traction strap on the strap spool of the return winch results in the rapid increase of the diameter is adopted to tow the sliding shuttle on the ejection runway to rapidly and automatically return; and the instantaneous rotation power of the strap spools is obtained from a main shaft through electromagnetic clutches at two sides of the strap spool, the rotation force of the main shaft is obtained through the connection of a shaft coupling and a speed adjustment motor, and the instantaneous braking force of the strap spool is obtained through the friction between the outer circle of the strap spool and the electromagnetic brake arranged on a base.

Description

technical field [0001] The invention relates to the technical field of military equipment or aircraft carrier aircraft catapults, in particular to a two-way drive winding acceleration type aircraft carrier aircraft catapult. Background technique [0002] At present, there are three main ways for carrier-based aircraft to take off on aircraft carriers. One is the steam-type catapult used on US aircraft carriers. The catapult uses steam as power to drive the towing hook through the piston in the open cylinder to pull the aircraft to accelerate take-off. The steam catapult equipment is bulky, takes up a lot of space, the manufacturing process is complicated, and consumes a lot of fresh water. Because the steam catapult in the United States uses a slotted cylinder, the steam leakage is large and the energy consumption is large. The cylinder seal uses The service life is short, and the maintenance cost is high. In severe cold regions or in winter, the leaked steam will freeze on ...

[0003] The second is the ski-jump flight deck on the Russian aircraft carrier, that is, the aircraft accelerates on the deck by itself and passes through an upwardly tilted runway to realize the ski-jump flight from the ship. The disadvantage of the ski-jump ejection method is that it must be built The ski-jump take-off platform must use a twin-engine aircraft with a large thrust-to-weight ratio. Single-engine fighters cannot be used, so the types of carrier-based aircraft are restricted

[0004] The third type of electromagnetic carrier-based aircraft catapult, the United States has successfully trial-produced it. It took more than 20 years and cost 2.6 billion. However, due to its large size, huge power consumption, overly complicated structure, and very unreliable stability, the U.S. military has not dared to equip aircraft carrier
