Keywords: Combat engine, Static Combat thrust class


Commenced in 1982, the XG40 programme is central to the demonstration of Rolls-Royce technology appropriate to the requirements of the advanced combat engine for mid 1990's operation. At the same time, the technology in scaled form is viewed as having wider application than for the advanced combat engine alone.

To meet the multi-role requirements of advanced twin and single engined fighters, the combat engine must be designed to give enhanced dry thrust, retain good dry specific fuel consumption and reduce reheated fuel consumption compared with current fighter engines. A thrust/weight ratio of 10 : 1 is targeted and at the same time requirements for operating cost, reliability and durability are stringent.

Advanced materials, manufacturing technology and design of structures have been incorporated to enable the required levels of reliability, durability, component cost and weight to be demonstrated.The engine is in the 90/95 kN nominal Sea Level Static Combat thrust class.
