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 ...
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
The EMALS uses a linear induction motor (LIM), which uses alternating current (AC) to generate magnetic fields that propel a carriage along a track to launch the aircraft. [5] [6] The EMALS consists of four main elements: [7] The linear induction motor consists of a row of stator coils with the same function as the circular stator coils in a conventional induction motor.

However, ski-jump launches cannot match the payloads made possible by high-speed catapult launches. [4] While aircraft such as the F/A 18 that are normally catapult-launched can make use of a ski-ramp, this typically comes at the cost of a reduced capacity for either fuel or munitions, and thus negatively impacting mission scope significantly.
