Differential aircraft carrier catapult

Abstract

The invention relates to a differential aircraft carrier catapult. An energy storage flywheel rotates to drive a first differential set, a second differential set and a third differential set at the same time. A right half shaft of a first differential of the first differential set is connected with a low-speed brake set and drives a high-speed brake set through a gear at a high variable speed. The low-speed brake set is started to enable the right half shaft of the first differential connected with the low-speed brake set to be braked and stop rotating, a left half shaft of the first differential obtains power to drive a rope winding roller, and the high-speed brake set is started accordingly. Before a steel wire rope wound by the rope winding roller enters a high-acceleration catapulting section, brake torque is supplementally supplied to the braked right half shaft of the first differential. The second differential set and the third differential set work in the same way. The second differential set or the third differential set carries out transmission on the rope winding roller through gears with different transmission ratios, so that the rope winding roller obtains different rotating speeds from the first differential set or the second differential set or the third differential set, the catapulting steel wire rope wound by the rope winding wheel drags a catapulting shuttle catapult ship carrier attacker, and different accelerated speeds can be selected.

Description

technical field [0001] The invention relates to an aircraft carrier catapult, in particular to a differential speed aircraft carrier catapult, which belongs to the technical field of aircraft carrier equipment. Background technique [0002] Steam catapults on aircraft carriers are low in efficiency, consume a lot of energy, require a lot of equipment maintenance, and consume a lot of fresh water; while electromagnetic catapults require 60MW of electric power for about 2 seconds each time they are ejected. The power supply is too large to be realized on an aircraft carrier. For example, by accumulating and storing electric energy for a certain period of time and then releasing it in a short period of time, it is most effective to use a wire coil, but it does need low-temperature cooling to maintain it at present; from the energy storage flywheel Getting power for ejection, high power coupling directly from the flywheel on the order of 2 seconds is very difficult.
