harder to measure. The four engines could propel the Lucy Ashton at a speed in excess of . A Derwent Mk.8 from a Gloster Meteor was used in the jet propelled car Thrust1, which was built by Richard Noble in 1977. This was an initial development car that paved the way for Thrust2, which Noble drove to set a new land speed record in 1982. Variants Derwent I – first production version, 2,000 lbf (8.9 kN) of thrust Derwent II – thrust increased to 2,200 lbf (9.8 kN) Derwent III – experimental variant providing vacuum for wing boundary layer control Derwent IV – thrust increased to 2,400 lbf (10.7 kN) Derwent 5 – scaled-down version of the Rolls-Royce Nene developing 3,500 lbf (15.6 kN) of thrust Derwent 8 – developed version giving 3,600 lbf (16.0 kN) of thrust Derwent 9 Applications Avro 707 Avro Canada C102 Jetliner Fairey Delta 1 Fokker S.14 Machtrainer Gloster Meteor Nord 1601 FMA I.Ae. 27 Pulqui I Argentine design flown in 1947 and preserved at the National Air Museum Tupolev '73' Tupolev '78' Specifications (Derwent I) See also Citations Bibliography Bridgman, L, (ed.)
