Adour MK 821 a natural progression for the IAF Jaguar

Earlier this month, Rolls Royce Turbomeca installed and demonstrated the performance of the Adour MK 821 turbofan engine on a Royal Air Force Jaguar at the RAF Station, DCAE Cosford. This was a ground-test. The Air Attache of the Indian High Commission in London was invited to witness the demonstration. Rolls Royce is pitching the MK 821 as a natural evoluation from the MK 811 that currently powers the IAF Jaguar. The company is also pitching from the angle that the new engine has a high degree of commonality with the Adour MK 871 which powers the Hawk trainer now in use with the IAF.

Rolls-Royce AJ65 Avon

Work commenced early in 1945 on the AJ65 axial flow turbo-jet with a design thrust of 6500 lb. This figure was reached in 1951 with the 100 series RA3. In 1953 the considerably redesigned 200 series RA14 was type tested at 9500 lb thrust. Development culminated in the 300 series RB146 which produced 17.110lb thrust with afterburning

On 1 April, 1943, Rolls-Royce assumed responsibility for the Power Jets W2B which, a month earlier, had made its first flight in the Gloster E28/39 at 1200lb thrust. Later known as the B23 Welland it was, during April, put through a 100 hr test at the design rating of 1600 Ib thrust. In June, 1943, it flew in a Gloster Meteor at 1400lb thrust. Production Welland-Meteors were in action against V-1 flying bombs in August 1944.

Rolls-Royce Trent 800

Developed from the RB211, the Trent covers a thrust range of 71,000 lb to 92,000 lb thrust, with the capability to grow beyond 100,000 lb. The Trent 800 features a 110 inch diameter wide-chord fan, high flow compressors and Full Authority Digital Engine Control (FADEC).
Detailed engineering design began in 1988 to meet the propulsion requirements of the Airbus A330 (Trent 700) and Boeing 777 (Trent 800). The Trent first ran in August 1990, and in January 1994 a Trent 800 demonstrated a world record thrust of 106,087 lb. The engine entered service in March 1995 in the Airbus A330.
