AFRL Technology Demonstration Program Gives Boost to Future Hydrocarbon and AR1 Engines
The HBTD program is developing key technologies for rocket engines that employ an oxygen-rich staged combustion (ORSC) engine cycle - the same cycle that is used for the Aerojet Rocketdyne AR1 engine - a potential replacement engine for the Russian RD-180. The reusable HBTD demonstrator engine is a 250,000 lbf thrust class engine that is capable of up to 100 flights, and features high-performance, long-life technologies and modern materials.
"The large quantity of data gathered during this test series is invaluable in anchoring the analytical models that were developed for use with this and future engine programs. We incorporated a novel fuel and oxidizer mixing technology in the preburner design, which yielded an extremely uniform gas temperature throughout the engine," said
"At Aerojet Rocketdyne, we evolve rocket science. The Hydrocarbon Boost Technology Demonstrator program is key to a state-of-the-art oxygen-rich staged combustion engine with components that include modern materials using advanced manufacturing techniques," said
The series of successful tests also marked the first use of the Mondaloy 200™ super alloy, which was developed jointly by
