GROUND-EFFECT VEHICLE Russian patent published in 2020 - IPC B60V1/08 B64C3/10 

FIELD: aviation.

SUBSTANCE: ground-effect vehicle has composite wing with center section 1 and cantilevers 2, end washers 3 in end sections of center section 1, power plant, vertical 4 and horizontal 5 fins. Component wing extension ≥2.5, center section 1 0.5÷0.9, cantilever relative area 2 0.25÷≤0.4, ground-effect vehicle longitudinal static moment 0.3÷≤0.6, horizontal fins 5 0.25÷0.55. Cantilevers 2 are equipped with stall delay mean made in the form of section of geometrical twist of cantilever 2 with installation angle decreasing as it approaches center section 1 and / or leading edge flap 7.

EFFECT: invention is aimed at improvement of safety due to provision of static, aperiodic and oscillatory stability of ground-effect vehicle and reduction of inductive resistance by stall delay on cantilevers of composite wing in area of their abutment to center section.
