Woodward in Rockford, Ill., is in the process of upgrading the GE T700 engine series with new fuel controls and a Full Authority Digital Engine Control (FADEC) system.
The company has contracted Unison Industries of Jacksonville, Fla., to provide three different speed and temperature sensors for the U.S. Army T700-GE-701D turbine engine fuel-metering unit (FMU).
The FMU takes advantage of Unison sensors designed to measure fuel temperature in the fuel delivery system, while also withstanding fuel pressure at elevated temperatures.
Also integrated into the FMU is a dual-channel speed sensor that determines and communicates the rotational speed of the engine core. Moreover, another Unison sensor continuously measures inlet air temperature.
“Unison’s sensors provide us with the ability to monitor the fuel control system and engine performance on some of the military’s key aircraft,” says John Foti, T700-GE-701D FMU development program manager at Woodward. “The information they deliver will help us reduce the cost of maintaining these engines and ensure their long-term reliability and safety in combat.”
Unison’s sensor technology will support the high-altitude, high-performance military aircraft powered by the T700-GE-701D engine. The GE T700 engine series currently powers 21 types of rotary and fixed-wing aircraft, including the Apache, Black Hawk, and Marine Super Cobra helicopters.
Unison will manufacture sensors for Woodward at its Jacksonville, Fla., and Norwich, N.Y., facilities.
