An aircraft catapult is a device used to help fixed-wing aircraft gain enough airspeed and lift for takeoff from a limited distance, typically from the deck of a ship. They are usually used on aircraft carrier flight decks as a form of assisted takeoff, but can also be installed on land-based runways, although this is rare.
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 compared to steam. EMALS was first installed on the lead ship of the Gerald R. Ford-class aircraft carrier, USS Gerald R. Ford, c. 2015.
An electromagnetic catapult, also called EMALS ("electromagnetic aircraft launch system") after the specific US system, is a type of aircraft launching system. Currently, only the United States and China have successfully developed it, and it is installed on the Gerald R. Ford-class aircraft carriers and the Chinese aircraft carrier Fujian.
Aircraft carriers could always use a little more room to make take off easier. The Navy has been helping itself with steam powered catapults for a while but the USS Ford has just installed an ...
Catapult officers, also known as shooters, are commissioned officers, and are responsible for all aspects of catapult maintenance and operation. They ensure that wind (direction and speed) is sufficient over the deck and that the steam settings for the catapults will ensure that aircraft have sufficient flying speed at the end of the stroke.
The Gerald R. Ford-class nuclear-powered aircraft carriers are currently being constructed for the United States Navy, which intends to eventually acquire ten of these ships in order to replace current carriers on a one-for-one basis, starting with the lead ship of her class, Gerald R. Ford (CVN-78), replacing Enterprise (CVN-65), and later the Nimitz-class carriers.
The US Navy’s 10 older carriers, the Nimitz class, rely on steam-powered catapults to launch aircraft. All the US carriers, however, will retain two key advantages over the Fujian: power and size.
CATOBAR (catapult-assisted take-off but arrested recovery [1] or catapult-assisted take-off barrier arrested recovery [2]) is a system used for the launch and recovery of aircraft from the deck of an aircraft carrier. Under this technique, aircraft launch using a catapult-assisted take-off and land on the ship (the recovery phase) using ...
