Rolls-Royce Avon
The Rolls- Royce Avon jet engine is the first Rolls- Royce with axial compressor and was produced until 1974, more than 11,000 times.
History
After the jet engines Welland, Nene and Derwent with radial compressor, the fourth type of Rolls- Royce ( 6,500 lb thrust Axial Jet, ) was from 1945 under the name AJ.65 developed. This version developed a thrust of 29 kN. After completion of the first prototype in 1947, the series production version RA.3/Mk.101 with individual combustion chambers began in 1950. Flygmotor provided under license Svenska own variants for the Saab 32 Lansen ( RA.3/Mk.109 than RM5 ) and Saab 35 Draken (improved RA.29 than RM6 ) ago. For the de Havilland Comet an uprated version RA.7/Mk.114 was built. With tube - annular combustion chamber followed by other types with even higher performance: RA.14/Mk.201 (42 kN), RA.26 (44 kN), RA.28/Mk.207 (45 kN). The highest thrust generated version RA.29 Mk.301 / 2 ( RB.146 ) for the English Electric Lightning, the 56.5 kN, with additional afterburner even delivered almost 73 kN thrust.
Rolls- Royce Avon are under the name RT48/RT56 as stationary drive eg used on oil rigs.
