Laminar flow control technology-based wing body fusion layout passenger plane layout method

The invention belongs to the technical field of aircraft design, and discloses a laminar flow control technology-based wing body fusion layout passenger plane layout method, which comprises a fuselage, wings and an engine, the fuselage and the wings adopt a wing body fusion layout, the wings are divided into cabin section wings and outer side wings, the cabin section wings are fused with the fuselage, the outer wings are arranged on the two sides of the cabin section wings, the engine is arranged on the rear portion of the fuselage, and the small V-shaped empennages are installed on the rear edges of the cabin section wings. The invention further discloses a passenger plane layout key method. According to the wing body fusion passenger plane designed by the invention, the frictional resistance is reduced by 46% compared with a conventional layout passenger plane, is reduced by 32% compared with the conventional wing body fusion layout passenger plane, the cruise lift-drag ratio reaches 28 and is increased by
