Advanced launch system (ALS): electrical actuation and power systems improve operability and cost picture

摘要

A brief status review of the advanced launch system (ALS) and its associated advanced development program are presented to demonstrate maturation of those technologies that will help meet the overall operability and cost goals. The electric power and actuation systems are highlighted as a specific technology ready not only to meet the stringent ALS goals (cryogenic fuel valves and thrust vector controls with peak power demands to 75 hp), but also those of other launch vehicles, military and civilian aircraft, lunar/martian vehicles, and a multitude of commercial applications.
