The Unitron GFC-37M Ground Power Unit (GPU) supplies power to a parked or hangared aircraft. A reliable GPU unit is a crucial piece of equipment for any hangar. In a small footprint, a GPU delivers specified power through the use of a standard electrical system, battery, fuel, and a small engine. This Unitron GPU includes lightweight 400 Hz and 28 VDC mobile converters for aircraft ground power applications and the lightest weight-to-power rating ratio on the market.

The purpose of an aircraft Auxiliary Power Unit (APU) is to provide energy for purposes other than propulsion - most often to operate a generator for electrical power. Although small piston-engine APUs were first used in aircraft on a limited basis during World War I, it was in World War II that they came to be used extensively on large aircraft.

The Apollo Service Propulsion System (SPS) engine provided the thrust necessary to launch the Apollo assembly into and out of lunar orbit.

The P&WC PT6 turboprop aircraft engine entered service in 1964 and continues to evolve, powering mid-size aircraft across the world.

The JT15D is Pratt & Whitney Canada’s first turbofan engine, powering a wide range of light to mid-size business jets since its inception in the 1970s.

Designed to sustain Mach 3 speeds at over 80,000 ft, the Pratt & Whitney J58 turbojet engine powered the Lockheed A-12 and SR-71.

In production from 1953-1986, the Continental O-470 family of engines are popular in light civil aircraft such as the Cessna and Beechcraft.

RATO or “Rocket Assisted Takeoff” is a type of assisted takeoff to help aircraft get airborne.

In the 1950s, the General Electric J47 turbojet powered several front-line military aircraft, including the North American F-86 “Sabre”.

The Fairchild J44R-24 is an axial-flow turbojet engine made in 1947 that powered missiles and drones for the US Navy.
