Near-space unmanned aircraft

Abstract

The invention discloses a near-space unmanned aircraft. Helium gas is inflated into an inflatable aircraft, solar wings are mounted at the front end of the inflatable aircraft, can rotate around flatter positions of rotary shafts at the roots of the wings by an angle ranging from -45 degrees to 80 degrees and can be locked at the three positions of a -45-degree angle, a 0-degree angle and a 80-degree angle. A plurality of propellers are mounted on the solar wings, two slantingly-rotatable trust propellers and two directional-trust auxiliary propellers are mounted on the inflatable aircraft, and solar cell panels are distributed on the surface of the solar wings and the inflatable aircraft. The inflatable aircraft is divided into a front section, a middle section and a rear section, wherein the rear section has a soft structure, a middle section has a semi-hard structure, and the front section is a task loading cabin. The near-space unmanned aircraft can overcome the defects of high requirements to taking-off and landing fields, insufficiency in effective load, poor safety in low-altitude flying and the like of an existing unmanned aircraft, and meanwhile, higher flight altitude can be realized, hovering posture and flight path control performances of the near-space unmanned aircraft are improved, absorption and storage of solar energy are improved and time for staying in space is guaranteed.

Description

technical field [0001] The invention relates to a near-space vehicle. Background technique [0002] Judging from the relevant research work carried out by countries around the world, solar-powered UAVs and high-altitude airships are the main research directions for future low-dynamic (flight Mach number less than 1) near-space (20-100km) aircraft. They have the characteristics of long time in the air, large load capacity, high flight altitude, and strong survivability. They can carry visible light, infrared, multi-spectral and hyper-spectral, radar and other information acquisition loads, various electronic countermeasure equipment, and communication and other energy relays. The equipment can be used as a means of obtaining regional information to improve battlefield awareness, and can also provide electromagnetic suppression, electromagnetic strike, field emergency communication relay and energy relay services. [0003] There are many solar-powered UAV projects under resea...

Problems solved by technology

[0006] In order to overcome the deficiencies of the prior art, the present invention provides an unmanned aerial vehicle in near space, which complements the advantages and disadvantages of solar-powered drones and high-altitude airships, so as to solve the problem of high take-off and landing site requirements for solar-powered drones, insufficient payload, and problems in taking off and landing. During low-altitude flight safety and other issues, at the same time achieve a higher flight altitude, improve its hovering attitude and track control performance, enhance solar energy absorption and storage capacity to ensure its air time
