A hybrid-electric propulsion vertical take-off and landing drone using a dual-mode power cabin

Abstract

The invention discloses a hybrid electric propulsion vertical take-off and landing drone using a dual-mode power cabin, which has symmetrical double-swept tail fins and a streamlined fuselage. Large-aspect-ratio canards and large-aspect-ratio wings are arranged in tandem along the fuselage; The UAV power system consists of two types of dual-mode power cabins, Type I and Type II, and a composite hybrid power supply system. Among them, the type I power cabin is installed at the tip of the wing, and the type II power cabin is distributed and installed inside the wing and at the tip of the empennage. In the take-off and landing mode, the vertical take-off and landing multi-blade folding propellers at the front of the two-type power cabins operate to provide take-off and landing thrust; On top of that, at the same time, the level-flying propulsion propellers at the rear of the Type I cabin provide forward thrust to achieve efficient cruise. The composite hybrid power supply system is responsible for the power supply tasks of the two types of power cabins and load equipment, and has the function of multi-channel and multi-source output control while realizing efficient power supply.

Description

technical field [0001] The invention belongs to the field of aircraft design, and relates to a hybrid electric propulsion vertical take-off and landing unmanned aerial vehicle, specifically, a hybrid electric propulsion vertical take-off and landing unmanned aerial vehicle using a dual-mode power cabin. Background technique [0002] The existing vertical take-off and landing fixed-wing unmanned aerial vehicles can basically meet the different requirements of vertical take-off and landing and peace flight cruise on the aerodynamic shape and power system, but its functions are mostly realized by structural variants or fixed-wing modifications. Among them, the structural variant The scheme achieves the purpose of vertical take-off and landing and peaceful flight and cruise through the tilting of the power unit or part or the whole wing, and the structural weight is relatively large; the fixed-wing modification scheme directly installs a lift rotor on the fixed-wing UAV, and the ...

[0002] The existing vertical take-off and landing fixed-wing unmanned aerial vehicle can basically meet the different requirements of vertical take-off and landing and peace flight cruise on the aerodynamic shape and power system, but its functions are mostly realized by structural variants or fixed-wing modifications. Among them, the structural variant The scheme achieves the purpose of vertical take-off and landing and peaceful flight and cruise through the tilting of the power unit or part or the whole wing, and the structural weight is relatively large; the fixed-wing modification scheme directly installs a lift rotor on the fixed-wing UAV, and the technical threshold is low , high reliability, but there are also problems such as weight redundancy and low cruise efficiency; although the existing canard layout vertical take-off and landing fixed-wing UAV does not have the redundant weight brought by the variant structure, its shape design More emphasis on functional verification, no efficient cruise function

At the same time, except for the fixed-wing modification scheme, other existing schemes mostly use a single power system to meet the use requirements in a large area, and the overall efficiency of the power system is relatively low
