Armstrong Siddeley Stentor

The Armstrong Siddeley Stentor, latterly Bristol Siddeley BSSt.1 Stentor, was a two-chamber rocket engine used to power the Blue Steel stand-off missile carried by Britain's V bomber force. One chamber was used for initial boost, then, 29 seconds after release the boost chamber was shut down and a smaller cruise chamber was used for most of the flight.

Design and development

It was fuelled by hydrogen peroxide / kerosene propellant chemistry.

The engine incorporated an integral tubular mounting frame which was attached by six lugs to the rear bulkhead of the missile airframe, the complete engine being enclosed in a tube-shaped fairing with the nozzles at the rear.
