Basic diagram of an onager, a type of catapult. A catapult is a ballistic device used to launch a projectile a great distance without the aid of gunpowder or other propellants – particularly various types of ancient and medieval siege engines. [1] A catapult uses the sudden release of stored potential energy to propel its payload.
The Onager was a Roman torsion powered siege engine. It is commonly depicted as a catapult with a bowl, bucket, or sling at the end of its throwing arm. Trebuchet: 4th Century BC China: Similar to the catapult, but uses a swinging arm to launch projectiles. It is usually considered to be stronger than the catapult. [4] Oxybeles: 375 BC Greece
A slingshot or catapult is a small hand-powered projectile weapon. The classic form consists of a Y-shaped frame, with two tubes or strips made from either a natural rubber or synthetic elastic material. These are attached to the upper two ends. The other ends of the strips lead back to a pouch that holds the projectile. One hand holds the ...
USS Intrepid showing her SCB-27C configuration.. The two sub-types of SCB-27 modifications were primarily a result of changes in catapult technology in the early-1950s. SCB-27A vessels used a pair of H 8 slotted-tube hydraulic catapults, while the later SCB-27C vessels were fitted with a pair of C 11 steam catapults, a British innovation (in fact the first four installed, on Hancock and ...
The Electromagnetic Aircraft Launch System (EMALS) is a type of electromagnetic catapult system developed by General Atomics for the United States Navy. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston , providing greater precision and faster recharge ...

CAM ship is an acronym for catapult aircraft merchant ship. [ 1 ] They were equipped with a rocket -propelled catapult launching a single Hawker Hurricane , dubbed a "Hurricat" or "Catafighter" to destroy or drive away an attacking bomber.
The torsion mangonel myth, or simply the myth of the mangonel, [1] is the belief that the mangonel (or traction trebuchet) was a torsion siege engine which used the tension effect of twisted cords to shoot projectiles. As an extension of the belief in the existence of a torsion-powered mangonel, some consider it to have been used until the ...
