The RZ.2 was a British design for a liquid oxygen (LOX) / kerosene-fuelled rocket engine to power the Blue Streak (missile).
The design was a development of the Rolls-Royce RZ.1 rocket engine, which had in turn been a development by Rolls-Royce of the Rocketdyne S-3D.[1] Rolls-Royce, Ansty was the design authority.[2]
Two variants of this engine were developed: the first provided a static thrust of 137000 lbf and the second (intended for the three stage satellite launch vehicle) 150000 lbf. The engines could be vectored by seven degrees in flight for guidance.
Some disconnected facts for arrangement:
The Efflux chamber of the engine was made of nickel tubes brazed together through which flowed kerosene down one tube and back up the adjacent tube via a manifold at the mouth of the chamber. After static firings, these chambers were checked by climbing inside the engine from beneath. The mouth was 6 ft in diameter but that of the throat was smaller, which restricted access to the inspector. In addition, during firing, the inside of the chamber became coated with fine carbon, making inspection a filthy procedure.
