The Armstrong Siddeley Stentor, latterly Bristol Siddeley BSSt.1 Stentor, was a two-chamber HTP rocket engine used to power the Blue Steel stand-off missile carried by Britain's V bomber force.[1][2] The high thrust chamber was used for the first 29 seconds, after which it was shut down and a smaller cruise chamber was used for the rest of the powered flight.[3][4][5]

Design and development

It was fuelled by hydrogen peroxide with kerosene.[1]

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.

Der Armstrong Siddeley Stentor, später auch Bristol Siddeley BSSt.1 Stentor war ein zweistufiges Raketentriebwerk, das der britische Hersteller Armstrong Siddeley ab 1960 baute. Es diente dem Antrieb der Lenkflugkörpers Avro Blue Steel, die von der britischen V-Bomberflotte genutzt wurden. Eine Brennkammer lieferte den Startschub und wurde 29 sec. nach dem Abschuss abgestellt. Die zweite, kleinere Brennkammer wurde für den Rest des Fluges genutzt.[1][2][3]
