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 ...
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 .
First developed in the early 1960s, [3] [5] the ALR-20 began appearing on B-52D bombers (before 1967) [6] and B-52Gs in 1967-1969. [7] [8] In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/ALR-20" designation represents the 20th design of an Army-Navy electronic device for passive countermeasures signal receiver.
Sensory Aid Device for visually impared individuals to navigate their environments. Device sent out pulses of light which, when reflected off of objects around the user, would give the user an auditory cue [159] AN/PVQ-31: Advanced Combat Optical Gunsight (ACOG) U.S. Marine Corps, U.S. Army [169] Trijicon
A mass driver or electromagnetic catapult is a proposed method of non-rocket spacelaunch which would use a linear motor to accelerate and catapult payloads up to high speeds. Existing and proposed mass drivers use coils of wire energized by electricity to make electromagnets , though a rotary mass driver has also been proposed. [ 1 ]
The Target Identification System Electro-Optical (TISEO) is the Target identification device used in the F-4 Phantom and F-14 Tomcat that provides sharp close-up images of hostile aircraft outside of visual range.
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 ...
The Mark I was a simple system that amplified the signals of the British Chain Home radar systems, causing the aircraft's "blip" to extend on the radar display, identifying the aircraft as friendly. Mark I had the problem that the gain had to be adjusted in flight to keep it working; in the field, it was correct only half the time.
