Rolls-Royce Dart RDA3 Mk506 – sectioned & motorised
1946, Stratosphere Chamber, On long term display
The first turboprop engine fitted to a commercial airliner, the Brooklands-designed and built Vickers Viscount, the Rolls-Royce Dart was a highly successful gas turbine engine widely used by the aircraft industry.
The first aircraft to fly totally under Dart power was Wellington LN7I5 in June 1948. The Vickers Viscount 630 G-AHRF made the first scheduled passenger service with Dart engines when it flew from London Northolt to Paris Le Bourget on 29th July 1950.
This sectioned example is believed to have been flown in an early Viscount 700 Series airliner with British European Airways. BEA apprentices later sectioned the engine as a training exercise and donated it to Feltham Air Training Corps in the late 1950s.
