Problems solved by technology

However, the span length of a wing with a large aspect ratio is much larger than the thickness and chord length of the wing, so there may be a problem of insufficient structural rigidity

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with accompanying drawing.

[0027] The aerodynamic layout of the tailstock type tandem wing long-endurance aircraft of the present invention has a cylindrical section fuselage 1, a large aspect ratio front wing 2 and rear wing 3, a vertical tail 4, a propeller engine 5 and a landing gear 6.

[0028] The front wing 2 is an upper single wing with a certain dihedral angle, preferably in the range of 2° to 10°, and has a certain sweep angle, preferably in the range of 0° to 30°, such as figure 2 shown. The front wing 2 is symmetrically installed on the left and right sides of the front half of the fuselage 1, and joins with the upper part of the outer wall of the fuselage 1; the front wing 2 has an aileron 7 on the outer rear edge to control the roll of the aircraft.

[0029] The rear wing 3 is a lower single wing with a certain dihedral angle, preferably in the range of 2° to 10°. The rear wi...

Abstract

The invention discloses an aerodynamic layout of a tailstock type tandem wing long endurance aircraft. A front wing and a rear wing which are bilaterally symmetric respectively are arranged at the front half section and the rear half section of a fuselage respectively; and a vertical tail is arranged at the tail of the fuselage. Dihedral angle difference is formed between the front wing and the rear wing; unfavourable interference effect of the front wing to the rear wing is reduced, and the whole aerodynamic characteristics of a double airfoil layout can be beneficially improved. A propeller engine is arranged on the front wing and the rear wing respectively, so that spanwise distance difference is formed between the propeller engines on the front wing and the rear wing, and the maneuvering capability of a quadrotor power system is enhanced. Meanwhile, a landing gear is arranged at the tail of the engine on the rear wing and the tail of the fuselage respectively.

Description

technical field [0001] The invention belongs to the field of aircraft aerodynamic layout design, and relates to a new vertical take-off and landing aircraft layout form, in particular to a tailstock type tandem-wing long-haul aircraft with four engines installed on the wings, which adopts the anhedral angle difference between the front and rear wings. The aerodynamic layout of the aircraft. Background technique [0002] Vertical take-off and landing aircraft are widely used because of their low requirements for take-off and landing conditions. From a military point of view, vertical take-off and landing aircraft can perform flight missions under special conditions such as aircraft carriers, small islands, reefs, and mountain forests. The United States has listed vertical take-off and landing aircraft that can adapt to complex terrain environments as one of the top ten key future equipment for the US military. one. From a civilian point of view, vertical take-off and landin...
