The paper first describes results of static aeroelastic calculations for a recent canard/cranked delta fighter project, in which a complete aircraft aerodynamic and structural model is used to demonstrate full-interacted 'free' aircraft deflection modes and resulting stability effects. The significance of these results is illustrated by comparison with corresponding 'fixed root' calculations, thereby indicating a requirement for complete aircraft aeroelastic modelling at the earliest possible stage in project design. Aeroelastic modelling of external stores in the context of store/aircraft integration is also discussed. Finally, the correction of high-speed wind-tunnel model results for aeroelastic distortion is addressed, indicating those parameters which are likely to be significantly affected.
