Investigation on the centre of pressure migration for different wing configurations

A wing-in-ground effect (WIG) craft experiences longitudinal instability due to its center of pressure (COP) location migrating when in transition from in-ground-effect (IGE) to out-of-ground effect (OGE) zone. The study on this subject has always been a grey area and only very limited published res...
