Upper Stage Engine Technology (USET)

Aerojet Rocketdyne and its supplier, Florida Turbine Technologies Inc. (FTT), of Jupiter, Fla. designed, manufactured, assembled and delivered the turbopump assembly to the AFRL test facility and successfully demonstrated steady state operation at 100 percent power. The USET program is an AFRL Integrated High Payoff Rocket Propulsion Technology (IHPRPT) program that started in 2003 and is focused on the next generation of physics-based modeling and simulation design tools that will reduce design time, lower cost and increase fidelity for the next generation engine.

The USET TPA was designed using this analytical capability while developing key technologies for insertion to a TPA for a new upper stage rocket engine. Aerojet Rocketdyne’s USET TPA is designed for a 45,000 pound-force of thrust upper stage engine and operates at 90,000 rpm. It is about the size of a swimming pool pump.

The Aerojet Rocketdyne/FTT team has developed the key analytical capability and technologies required for a next generation upper stage rocket engine. We’ve demonstrated and validated the models and technologies that will ensure an affordable program and much shorter development schedule than previously possible.
