Designed in 1946 with a two-stage centrifugal compressor by a team under Lionel Haworth using experience gained with the earlier Rolls-Royce Clyde, the Dart engine was initially rated at 890 shp and first flew in the nose of a converted Avro Lancaster in October 1947. Improvements in design led to the Dart RDa.3 of 1,400 shp which went into production for the Viscount in 1952. The RDa.6 increased this rating to 1,600 shp, and the RDa.7, thanks to a three-stage turbine, increased this to 1,800 shp.
Later Darts were rated up to 3,245 ehp, remaining in production until 1987, with some 7,100 having been produced having flown some 170 million flying hours.
Largely associated with the very successful Vickers Viscount medium-range airliner, it powered a number of other European and Japanese designs of the 1950s and 60s and was also used to convert American-manufactured piston aircraft to turboprop power. The list includes:
Fokker F27 Friendship : Small airliner from Dutch aerospace and aviation manufacturer Fokker. The original model on which several other airliners were based (such as the abovementioned F-27 and FH-227).
Grumman Gulfstream I (G-159) : Executive transport & small airliner. Includes the stretched Grumman Gulfstream I-C (G-159C).
Power output was around 1,500 hp (1,120 kW) in early versions, and close to twice that in later versions, such as those that powered the NAMC YS-11 airliner. Some versions of the engine were fitted with water methanol injection, which acted as a power restorative in hot and high conditions.
