Kestrel (rocket engine)

The Kestrel engine is an LOX/RP-1 pressure-fed rocket engine. The Kestrel engine was developed in the 2000s by SpaceX for upper stage use on the Falcon 1 rocket. Kestrel was built around the same pintle architecture as the SpaceX Merlin engine but does not have a turbo-pump and is fed only by tank pressure. Thrust vector control is provided by electro-mechanical actuators on the engine dome for pitch and yaw. Roll control (and attitude control during coast phases) is provided by helium cold gas thrusters.
