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 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 ...
Once the catapult fires, the hold-back breaks free as the shuttle moves rapidly forward, dragging the aircraft by the launch bar. The aircraft accelerates from zero (relative to the carrier deck) to about 150 knots (280 km/h; 170 mph) in about 2 seconds. Typically wind (natural or ship motion generated) is blowing over the flight deck, giving ...
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.
An improvement on the Nimitz class' steam-powered catapult, the EMALS has a higher launch capacity, sending aircraft barreling down the 300-foot track at over 150 miles per hour.
Aircraft catapult system in action (without an aircraft). CATOBAR is a system used for the launch and recovery of aircraft from the deck of an aircraft carrier.Under this technique, aircraft are launched using a catapult-assisted take-off and landing on the ship using arresting wires.
The aircraft is attached to the shuttle using a tow bar or launch bar mounted to the nose landing gear (an older system used a steel cable called a catapult bridle; the forward ramps on older carrier bows were used to catch these cables), and is flung off the deck at about 15 knots above minimum flying speed, achieved by the catapult in a four ...
It is larger and features a modern flattop design that includes an advanced electromagnetic catapult launch system, similar to the technology on the new US Ford-class carriers. China effectively ...
