The Advanced Propellants and Combustion Laboratory, located in the Gas Dynamics Building of the Maurice J. Zucrow
Laboratories, houses two control rooms (virtual tour)
and three test cells for jet, rocket, and propellant development. Test fires
are conducted and observed from the control room via a LabVIEW virtual interface program, which operates the valves
and acquires instrumentation data, and video monitors.
Advanced Propellants and Combustion Laboratory (APCL)
Students involved with class or sponsored research projects at APCL have designed and assembled engine hardware, modified or improved the testing capabilities as needed, performed test fires, and analyzed data. APCL has conducted test fires and experiments for several companies and organizations including Aerojet, Air Force Research Labs, Ballistic Missile Defense Organization, Boeing, NASA Dryden, NASA Marshall, Pratt & Whitney, Rolls-Royace/AADC, and TRW/Northrop Grumman.
