The Effect of Engine Dimensions on Supersonic Aircraft Performance

• In aircraft design a critical part of the design isthe engine selection. This is typically making aselection from exiting engines. Looking at a nextgeneration future fighters, however, where thetime of deployment may be 20-30 years in thefuture this is not a valid approach as there willbe an evolution in the engine designs. E.g. anew European fighter aircraft will most likelybe a collaborative project also involving thedevelopment of an engine for that aircraft. Inthis study conceptual engine-airframe co-designis demonstrated, using models of comparablefidelity for both the engine design and theaircraft design. This co-design leads to a deeperunderstanding of the tradeoffs from both sides,and means that also more radical designs andinnovations can be evaluated in a fair way.
