Hybrid buoyant body solar flight device

Abstract

The invention discloses a hybrid buoyant body solar flight device. The hybrid buoyant body solar flight device comprises a fuselage shell, a wing shell, a tail wing shell and a propeller, wherein thewing shell is located at the front end of the fuselage shell, and the tail wing shell is located at the tail part of the fuselage shell; the surface of the fuselage shell and the surface of the wing shell are each provided with photovoltaic coated cells, a plurality of vacuum pumps are arranged at the top end of the fuselage shell, and airborne equipment is arranged under the fuselage shell; a motor is arranged on the wing shell, and the motor is connected with the propeller; and the fuselage shell, the wing shell and the tail wing shell are each internally provided with a fairing. According to the hybrid buoyant body solar flight device, high-altitude buoyancy can be realized, different flying states can be adapted to, the posture of an aircraft without a rudder surface can be adjusted, the operation is convenient, and long-time high-altitude permanent endurance can be realized.

Description

technical field [0001] The invention relates to a flight device, in particular to a hybrid buoyancy body solar flight device. Background technique [0002] In the future, the aircraft that will achieve long-term (permanent) endurance at high altitudes. The existing photovoltaic-powered aircraft technology is mainly divided into two categories. Battery energy storage or gliding (potential energy storage) to achieve long-term (permanent) empty space. However, the aircraft must be able to store enough electricity or potential energy. Storing electricity requires a lot of weight, and the electricity or potential energy accumulated when there is light may not be able to meet the needs of day and night flight. The other is a solar-powered airship, which mainly relies on the buoyancy of hydrogen or helium to stay in the air, and solar energy provides forward power. But the existing problem is that the high-altitude air is thin, the buoyancy is greatly reduced, and it is necessary...

AI Technical Summary

Problems solved by technology

But the existing problem is that the high-altitude air is thin, the buoyancy is greatly reduced, and it is necessary to carry an air tank to adjust the internal pressure of the airship at any time to reduce the pressure difference and increase the buoyancy

At the same time, hydrogen and helium are small molecular gases, which can easily escape through films or gaps, so the airship needs to carry additional gas to compensate

Moreover, the airship has a large wind area, so it needs a very large size to realize the effective load. To realize the route control under the high air flow, especially under the cross wind, the power, structural strength, weight and cost will be very big challenges.
