The Avon was tested in mid 1947. At 6000lb static thrust it made its first public display at the 1948 Farnborough Show in a Lancastrian flying test-bed (two outboard motors). The engine has been developed in power from 6000 static thrust to 14000lbs or approx 6000 to 13500hp. The amount of air these engines use per hour is approximately 5 tons to 11 tons respectively.
The Avon has been part of many achievements: The first British aircraft to go beyond the speed of sound (Hunter & Swift); The first engine to take an aircraft over 1000mph (Fairey Delta 2)
