The ascent propulsion system (APS) or lunar module ascent engine (LMAE) is a fixed-thrust hypergolic rocket engine developed by Bell Aerosystems for use in the Apollo Lunar Module ascent stage. It used Aerozine 50 fuel, and N2O4 oxidizer. Rocketdyne provided the injector system, at the request of NASA, when Bell could not solve combustion instability problems.

Mesin ini mengunakan bahan bakar Aerozine 50, dan pengoksidasi N2O4. Rocketdyne menyediakan sistem injektor, atas permintaan NASA, ketika Bell tidak bisa memecahkan masalah ketidakstabilan pembakaran. (in)

Ele usava Aerozine 50 como combustível, e tetróxido de nitrogênio (N2O4) como oxidante. A Rocketdyne forneceu o sistema de injeção sob requisição da NASA, quando a Bell não conseguiu resolver os problemas de instabilidade da combustão. (pt)
