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.
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 .
On March 31, 2016, GA-EMS, in collaboration with the U.S. Navy, conducted the arrestment of an F/A-18E Super Hornet [2] at the Runway Arrested Landing Site (RALS) located at Joint Base McGuire–Dix–Lakehurst, New Jersey. Previously, AAG tests had only involved inert loads simulating the weight of aircraft at a jet engine testing track ...
The Electromagnetic Systems (EMS) Group is a supplier of electromagnetic systems and related power equipment for a variety of defense, energy, and commercial transportation applications. EMS is a major factor in applying electromagnetic technologies to aircraft launch and recovery ( EMALS and AAG System), projectile launch (Navy railgun ), and ...
The others were the steam catapult and the angled flight deck. The mirror landing aid was invented by Nicholas Goodhart . [ 2 ] It was tested on the carriers HMS Illustrious and HMS Indomitable before being introduced on British carriers in 1954 and on US carriers in 1955.
Patient being loaded into a Seattle Medic One ambulance circa 1970 Seattle Paramedic Unit King County Paramedic Unit. In 1968, motivated by the work of Frank Pantridge, cardiologist Leonard Cobb proposed to the chief of the Seattle Fire Department, Gordon Vickery, training firefighters to treat cardiac arrest.
EMAS bed after being run over by landing gear. An engineered materials arrestor system, engineered materials arresting system (EMAS), or arrester bed [1] is a bed of engineered materials built at the end of a runway to reduce the severity of the consequences of an aircraft running off the end of a runway.
The EMS Authority manages the state's medical response to major disasters. This includes maintenance, staffing and deployment of three 200-bed mobile field hospitals, 39 Disaster Medical Support Units that supply ambulance strike teams, and three 40-person medical assistance teams that are prepared to respond to a disaster.
