Up to and during World War II, most catapults on aircraft carriers were hydraulic. United States Navy catapults on surface warships, however, were operated with explosive charges similar to those used for 130-millimeter (5-inch) guns.

In a hydraulic catapult, a system of pulleys multiplies the motion of a hydraulic ram belowdecks. The wire running over the pulleys is only so strong. Beyond a point, the wire breaks and the catapult fails.

2022年6月24日 · Abstract: A hydraulic catapult system is proposed to simulate the movement of the missile in the launch tube, which mainly consists of a high-speed hydraulic cylinder, an accumulator group, a main valve, a servo valve and a cable pulley mechanism.

On 15 November 1934, the Bureau of Naval Aeronautics established plans to install hydraulic, flush-deck catapults on the USS Yorktown (CV-5) and USS Enterprise (CV-6).

This section contains general instructions for the inspection and maintenance of the bridles and pendants which are employed in conjunction with the different types of aircraft which are launched from hydraulic catapults.

Warship - Aircraft, Armament, Defense: The main technical development in aircraft carrier design during World War II was the hydraulic catapult, but this was barely powerful enough to launch the heavier jet aircraft coming into service after 1945.
