Executor is a rocket engine developed by ARCA for use on its Haas rocket series and on IAR 111 Excelsior supersonic airplane. Executor uses kerosene and liquid oxygen as propellants in a gas-generator power cycle.
The injector of Executor is of the pintle type that was first used in the Apollo Program for the lunar module landing engine.
Propellants are fed via a single shaft, dual inducer-impeller turbo-pump. The turbine exhaust gases are used for attitude control of the Haas 2 rocket.
