Thrust-Vectoring Upgrade for Typhoon Eurojet EJ200? - Defense Update - Military Technology & Defense News

According to Eurojet, a Typhoon equipped with thrust vectoring nozzles (TVN) could reduce fuel burn on a typical mission by up to 5%, while increasing available thrust in supersonic cruise by up to 7%. Typhoon is already capable of performing ‘super-cruise’ (flying supersonically without afterburner) and the proposed modification will further increase this capability. Other cost saving aspects of thrust vectoring include the potential to extend engine life by reducing operating temperatures at a given power setting. It could also be used to reduce take-off and landing distances and approach speed. Beside the operational cost savings, TVN enhances the aircraft maneuvering as it becomes a ‘virtual control surface’ when coupled with the aircraft flight-control system. Another aspect is improving the aircraft ability to carry an asymmetric weapons load.



TVN for the Eurofighter? - Armada International
According to Eurojet officials, the adoption of the TVN should decrease fuel consumption on a standard mission by about three per cent, while in the afterburner mode the hot section temperature could be lowered. 10° K less during take-off and 10 to 20° K less at high altitude, with beneficial effects on the engine life. As for performances, a seven per cent increase in supercruise mode has been realised during simulations. The TVN would also become a third attitude control system besides the forward canard surfaces and the wing mobile surfaces, thus increasing redundancy and survivability in combat. The TVN also allows better aircraft behaviour when asymmetric payloads are carried, avoiding the need to use mobile surfaces to trim the aircraft, something that considerably increases drag and therefore fuel consumption.
