Napier N.ScD.n Double Scorpion rocket motor

The installation of the Napier N.ScD.n Double Scorpion rocket motor on English Electric Canberra B.2 WK163. This clearly shows the High Test Peroxide (HTP) oxidiser tank in the forward bomb bay and the double-barrelled thrust chambers, mounted at the rear. (Location: Napiers flight test unit at Luton Airport) The Double Scorpion (N.ScD.n) engine was simultaneously developed with the single-chamber Scorpion, consisting of two Scorpion engines mounted together with each unit individually controllable, developing double the thrust. From 1956 Double Scorpion engines were fitted experimentally to two Canberra light bombers, to improve high altitude performance. On 28 August 1957 WK163, fitted with a Double Scorpion, broke the world altitude record, exceeding 70, 000 ft (21, 000 m). (Wikipedia) WK163 (msn 71399) was delivered to Napier at Luton on 28 January 1955, later sold and placed on the UK register as G-BVWC, moved to Baginton, then Doncaster
