Abstract

A medium thrust engine for transfer and injection missions, using earth storable propellants, is defined by analyzing the different mission requirements and by considering propulsion system aspects, engine technological and economical aspects. The primary choice is a pressurefed, 5 kN engine with a down-rating capability to 3,5 kN by throttling. Uprating potential to 15 kN is provided by a turbopump fed version with higher chamber pressure. The chamber is mainly film cooled with additional regenerative throat cooling to provide the long burning time capability required. Test planes, development cost and schedules are evaluated assuming the engine ready for operation when ARIANE 4 becomes operational.
