The carrier-based propeller transport aircraft has a compact layout, where the large nacelle in size and weight is sensitive to propeller slipstream, and thus calls for sophisticated flight load design studies, which are still insufficient considerin

Missiles may be damaged when aeroservoelastic problem occurs, which is caused by the interaction of structure flexibility and flight control system. Because of the limit of wind tunnel test condition, numerical methods are mostly used in previous aer
