Cluster-type bionic solar power unmanned aerial vehicle

Abstract

The invention discloses a cluster-type bionic solar power unmanned aerial vehicle. The cluster-type bionic solar power unmanned aerial vehicle adopts a flying wing type layout of a minimum control configuration and adopts a conventional ultralight material and structure, so that structural intensity is high, a risk of fluttering aeroelasticity is not in the presence in a covered wire, the unmannedaerial vehicle is environmentally friendly, and the bionic albatross-like appearance of the unmanned aerial vehicle is favorably blended with a natural environment. Three or more unmanned aerial vehicles are used for realizing aerial synergetic marshaling, and an effect that wing tip vortexes are mutually weakened and offset is used so as to further improve a lift-drag ratio and prolong enduranceand voyages. The unmanned aerial vehicle increases a wing area to increase a solar cell panel laying ratio, meanwhile, a control surface is simplified, so that a bare area is fully reduced, and frictional resistance is reduced. A power system selects an outer rotor brushless electric machine, an electronic speed regulator and a high-efficiency propeller are arranged, so that the power system meets efficient flight required by hand-throwing takeoff and long endurance, the aerodynamic design of the unmanned aerial vehicle enables the unmanned aerial vehicle to own good glide performance and self-stability, and the unmanned aerial vehicle can carry varied loads to finish different flight tasks.

Description

technical field [0001] The invention relates to the design field of long-endurance unmanned aerial vehicle, in particular, relates to a bionic solar-powered unmanned aerial vehicle which combines a solar-powered aircraft with an aerodynamic layout of a bionic bird shape, which is environmentally friendly and highly efficient for long-term cruise. Background technique [0002] Solar drones rely on non-polluting solar clean energy, which can achieve long-duration flight that is difficult to match with conventional energy sources. At present, the technologies for obtaining solar energy mainly include photocatalysis, solar panels, and solar heating. Solar energy is converted into electrical energy, so it has been applied to a certain extent in aircraft. However, due to the low energy density of solar energy, it can reach 900 watts per square meter in sunny summers, but only 100 watts per square meter or even lower in winter or rainy days. The conversion rate of lightweight solar...

Problems solved by technology

Therefore, the main problem brought by the super-large aspect ratio to solar-powered aircraft is that the structural strength is generally low, resulting in poor survivability, serious aeroelastic effect, and even flight accidents.
