Embodiment Construction

[0018] The tandem wing system uses Fluent software to carry out aerodynamic analysis to determine the horizontal relative distance S and the vertical relative distance H between the front wing and the rear wing (see Figure 4 ), by analyzing that S is 5 times the chord length and H is 0.4 times the chord length, the tandem wing system has better aerodynamic performance. The front wing of the tandem wing is a rectangular wing plus a trapezoidal wing and the dihedral angle of the front wing is 5, the length of a single dihedral section is 1 / 5 of the span length of the wing, the rear wing is a straight wing, and the aspect ratio is 10.

[0019] The root-to-tip ratio of the trapezoidal wing section is 0.8.

[0020] The motor is a disc motor to drive the paddle with a large diameter, and the position of the motor is 35% of the half length of the fuselage.

[0021] The power system 1 is a large-capacity lithium battery, ESC, MPPT (Peak Power Tracker), etc. During the day, the solar...

Abstract

A tandem wing layout solar long-endurance and high-altitude aircraft comprises a tandem wing system front wing, a tandem wing system rear wing 3, a vertical empennage 6 and a plane body 4, motors are arranged at the left and the right of the front wing, an electrical system 1 is arranged in the plane body, solar cell panels 3 are arranged in the front wing and the rear wing, and the surfaces of the front wing and the rear wing use transparent film sheaths. The problem of insufficient power is solved through increasing the laying area of the solar cell panels. Pneumatic layout of the solar plane with excellent pneumatic performances provided by the invention makes the solar plane have a good structure layout. The tandem wing solar unmanned plane has the following advantages: the layout configuration has the advantages in structure and quality, and the flight induction resistance of the airplane wings is obviously reduced through changing the lift distribution of the two front wing and the rear wing; the pneumatic performances of tandem wing layout are better than those of single-wing layout, so the upside potential of the pneumatic performances is large; and the laying of the solar cell panels is convenient, the geometric dimension is small, and the tandem wing solar unmanned plane is simple to make and has high practicality.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle design, and relates to a long-endurance high-altitude aircraft with tandem wings and solar energy. Background technique [0002] With the development of the aviation industry, energy, noise and pollution problems will become more and more obvious. Solar aircraft, a zero-carbon and environmentally friendly aircraft that uses photovoltaic cells, has some irreplaceable advantages of conventional aircraft and is bound to become a hot spot for development. [0003] Solar-powered drones require the aircraft to have a high lift-to-drag ratio, and the tandem layout scheme has obvious advantages in this regard. In addition to the structural and mass advantages of this layout configuration, the flight-induced drag of the aircraft wings can be significantly reduced by changing the lift distribution between the front and rear wings. In the case of the same reference area, wingspan and other main param...
