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.
Simple slingshot. 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 ...
The catapult used on aircraft carriers consists of a track or slot built into the flight deck, below which is a large piston or shuttle that is attached through the track to the nose gear of the aircraft, or in some cases a wire rope, called a catapult bridle, is attached to the aircraft and the catapult shuttle.
If SVG files are required, it is recommended that structure diagrams be exported as enhanced metafiles (.emf) which can be read by Inkscape and other image editors. From the "Options" menu, choose "Set Structure Drawing Style" → ACS Style; Draw the structure or reaction diagram; Export the file as PNG or EMF for further processing (see below)
F/A-18 attached to steam catapult preparatory to launch. A well-known type of assisted takeoff is an aircraft catapult. In modern systems fitted on aircraft carriers, a piston, known as a shuttle, is propelled down a long cylinder under steam pressure. The aircraft is attached to the shuttle using a tow bar or launch bar mounted to the nose ...
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.
The word mangonel was first attested in English in the 13th century, it is borrowed from Old French mangonel, mangonelle (> French mangonneau). [6] The French word is from Medieval Latin manganellus, mangonellus, diminutive form of Late Latin manganum, itself probably derived from the Greek mangana, "a generic term for construction machinery."
The template offers complex formatting and labeling options to control the output. Typically, each use is made into its own template, and the template is then transcluded into the article. See an example here, and an example of it being used in an article here. The use of fixed images, such as File:Narnia Timeline.svg, was common in the past ...
