DISC-SHAPED AIRCRAFT WITH DUAL SPINNING DISCS

摘要

Disclosed is a disc-shaped aircraft with dual spinning discs, comprising an engine, an upper fuselage, a lower fuselage, an upper spinning disc and a lower spinning disc. An upper cover is arranged at the bottom of the upper fuselage, and a lower cover is arranged at the top of the lower fuselage. The upper and lower covers are connected as a whole through an axle tube. A central gear is installed on the axle tube. The lower spinning disc is installed on the central gear and the upper spinning disc is located above the lower spinning disc. The engine is fixed on the lower cover and drive the central gear so that the upper and lower spinning discs are driven to rotate. Helical blades of the upper and lower spinning discs are opposite in rotary direction, angle of attack and installation angle, so that the problem of rotary balance of the fuselage is solved. The disc-shaped type aircraft provided by the invention is simple in structure, light in weight and low in cost, and can save much lifting power.
