A Miniature Solar Reconnaissance Aircraft Combined with Coanda Effect

Abstract

The invention relates to a micro solar reconnaissance flight vehicle incorporated with a Coanda effect. The micro solar reconnaissance flight vehicle comprises a propeller, a plurality of solar cell panels, a power control unit and a balance control unit, wherein the plurality of solar cell panels are symmetrically erected with a rotating shaft as center; an edge frame of each solar cell panel is fixedly arranged on a carbon fiber ring; the gaps of the solar cell panels are uniform and connected with a bottom circular framework of the flight vehicle; the axis of the propeller coincides with the rotating shaft on which the plurality of solar cell panels are erected; the propeller is positioned at the top; the areas of the erected solar cell panels are greater than that of the surface of the propeller; the plurality of solar cell panels are erected beyond an airflow area generated by the propeller; and total center-of-mass of motors in the power control unit and the balance control unit coincides with a symmetric line of a frame. The micro solar reconnaissance flight vehicle incorporated with the Coanda effect, provided by the invention, is advantaged in that full solar endurance is realized; the volume of the micro solar reconnaissance flight vehicle is small; the weight of the micro solar reconnaissance flight vehicle is light; the heat value of the micro solar reconnaissance flight vehicle in operation process is less; and the micro solar reconnaissance flight vehicle flies stably, hovers in the air for a long time and can be used for transmitting passenger flow and traffic flow in real time.

Description

technical field [0001] The invention relates to an aircraft, in particular to a miniature solar reconnaissance aircraft combined with the Coanda effect. Background technique [0002] At present, the structures of aircraft capable of hovering and vertical take-off and landing mainly include single-rotor helicopters, dual-rotor helicopters, tilt-rotor aircraft, and multi-rotor aircraft. Both are large aircraft that require a pilot to drive, and the endurance is limited by the capacity of the fuel tank. [0003] Existing quadcopters have poor battery life. The aircraft consumes stored energy during flight, and the energy cannot be replenished during flight. The capacity of the aircraft battery determines the maximum flight distance of the aircraft. [0004] At present, there are roughly three types of small aircraft on the market. The fixed-wing type has a small detection range and short battery life. For rotorcraft, the efficient utilization of power energy cannot be solved,...

AI Technical Summary

Problems solved by technology

For rotorcraft, the efficient utilization of power energy cannot be solved, and the engine accounts for a large proportion

For the flapping wing bionic model, the aerodynamic characteristics at low Reynolds numbers are still in the research and exploration stage, the anti-interference ability has not been well resolved, and the endurance is poor, most of the flight time is about 20 minutes

[0005] The solar-powered aircraft of Jilin University is the closest to the proposal of this application, but his aircraft structure is too complex, difficult to operate, very inconvenient to assemble, and the whole set of aircraft is expensive
