Junkers Jumo 211

1936, Stratosphere Chamber, On long term display

The Jumo 211 was the most-produced German engine of the Second World War: with over 68,000 built to power the Heinkel He-111 H series, and the Junkers Ju 87 and Ju 88 bombers.

On 27th September 1940, as part of the German air offensive during the 'Battle of Britain', a Junkers Ju 88 A-1 twin-engined bomber was shot down during an attack on the aircraft factories at Brooklands. Anti-aircraft gunners around Weybridge fired at it first before it was attacked by Hawker Hurricanes, causing the aircraft to crash near Dorking.

This Jumo 211 engine and supercharger were recovered when the crashed aircraft was excavated by the Air Historical Group and the Southern Area Wartime Aircraft Preservation Society in 1976. The second engine from the crashed aircraft is displayed at the Canadian National Aviation Museum in Ottawa.
