Atec’s Model 5400 Series Electronic Engine Throttle System replaces antiquated mechanical and electrical throttles used in the testing of a variety of engine types. It enables fast changeover between engine types in the same hush house or test facility. Designed for both commercial and military engine test markets, the Electronic Engine Throttle System is compatible with both FADEC and mechanical PLA engines and is available in a single throttle control version to support thrust engine variants and a multiple control version to support the turboshaft/turboprop engine market.

Digital electronic controls and servomotor technology ensure precision control and smooth operation. Problems such as drift, offset/repeatability and temperature/vibration susceptibility experienced with other throttle systems in the market have been eliminated. It also eliminates kinks and other routing issues associated with the length of the mechanical cable typically installed in A/F32T-9/T-10 hush houses. As an additional benefit to military customers, the model 5400 is a direct fit into the USAF’s A/M37T-20 cab used in Mobile Engine Test Systems.

Atec’s advanced throttle system can also be operated via RS232 communication protocol from a remote control system. The RS232 output provides feedback for the PLA and throttle positions. Communication and remote commands are in ASCII format that make interfacing with user-graphical programs easy.
