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.
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 ...
Rapid launch also minimized the time the aircraft carrier had to deviate from its intended course to conform to wind direction. [6] USS Saratoga using flight deck storage while landing aircraft in 1935. When the planes returned from their mission, the aircraft carrier again turned into the wind and began recovering aircraft over the stern.
A carrier-based aircraft (also known as carrier-capable aircraft, carrier-borne aircraft, or carrier aircraft) is a naval aircraft designed for operations from aircraft carriers. Carrier-based aircraft must be able to launch in a short distance and be sturdy enough to withstand the abrupt forces of launching from and recovering on a pitching deck.
Traditionally an aircraft carrier is supposed to be one ship that can perform at least power projection and sea control missions. [7] An aircraft carrier must be able to efficiently operate an air combat group. This means it should [citation needed] handle fixed-wing jets as well as helicopters. This includes ships designed to support ...
For Northrop Grumman , today is the day of days. The U.S. Navy plans to conduct the first-ever test launch of Northrop's new X-47B carrier-launched drone from an aircraft carrier (natch). X-47B ...
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.
A nuclear-powered aircraft carrier, like American carriers, would be a major jump for China, giving its navy a global reach. ... Both, however, featured a ski jump for aircraft launch.
