The Chemical Propulsion Research Complex (CPRC) develops advanced chemical propulsion concepts and evaluates safer propellants for launch vehicles, spacecraft thrusters and advanced ignition systems for next generation launch vehicles. It has the capability to perform sea level and simulated altitude testing, as well as advanced plume diagnostics. Workhorse hardware is available to perform component level testing. The testing facilities that comprise the research complex are highly configurable and able to meet varying customer needs. These facilities include the Altitude Combustion Stand (ACS), and CPRC cells 31 and 32.
