Abstract

Abstract

In order to investigate the aerodynamics of the wing-in-ground craft flying near wavy surface the dedicated wavy ground floor and moving wavy belt are devised to simulate the real water wave with the height of one meter. The wavy ground floor is capable of varying its vertical and horizontal position. The moving wavy belt which contains two waves on the belt is suitable for the wind tunnel test of the wing-in-ground craft flying over all the phases of the wave. The wind tunnel test has been carried out which simulates the wing-in-ground craft flying in the sky, near smooth surface and wavy surface by means of flat ground floor, wavy ground floor and moving wavy belt, respectively. The wind tunnel test results show that propellers and the floor have a coupling effect on the taking-off and landing aerodynamics of the wing-in-ground craft, instead of simple superposition. What is more, the aerodynamic loads of the wing-in-ground craft fluctuate dramatically over the various phases of the wave.
