| Abstract: | Longitudinal static stability is one of the major technical difficulties for a wing-in-ground effect(WIG) craft.The characteristics of longitudinal static stability for a canard type WIG craft were studied by numerical simulations.Firstly,comparisons were made between conventional airplane type and canard type on longitudinal static stability in ground effect.Then,effect of the canard wing was concerned with changing the aspect ratio.The present study provides theoretical basis for the design and research o... |
