GE developed a variable afterburner for the engine, although electronic control linked with engine controls had to wait until the J47. [5] Marrett describes one of the potential consequences of manual control of the engine and afterburner on a turbine engine: if the afterburner lit but the pilot failed to ensure the nozzle opened, the RPM ...
Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...
GE claims to have combated this by using simple pressure driven valves rather than complex mechanically actuated valves to divert airflow. GE stated that this system resulted in the variable cycle system adding only 10 lb to the engine. [3] Additionally, a production F120 engine was expected to have 40% fewer parts than the F110 engine.

GE-J79-3 and Lockheed YF-104A Starfighter XJ79-GE-1 Prototype. First ground static test run on 8 June 1954 produced 14,350 lbf (64 kN) with afterburner. [17] YJ79-GE-1 Flight test engines were designated YJ79-GE-1. J79-GE-2 Powered the McDonnell F4H-1 Phantom (F-4A), 16,100 lbf (72 kN) of afterburner thrust. J79-GE-2A essentially similar to the ...
In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...
In 1986, GE Fanuc Automation Corporation was jointly established in the US by FANUC and General Electric (GE). Under the joint venture company, three operating companies, GE Fanuc Automation North America, Inc., in the U.S., GE Fanuc Automation Europe S.A. in Luxembourg, and Fanuc GE Automation Asia Ltd. in Japan were established (the Asian company was established in 1987).
