Problems solved by technology

However, since the rotor of the rotorcraft is stationary relative to the central axis of the rotor, the forward resistance is relatively large, so the energy consumption is large, the aerodynamic efficiency is low, and it is difficult to fly with high power and long endurance

Embodiment 1

[0034] Example 1: Combining figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 and Figure 7 , a high-voltage wire inspection drone that uses two curtains with fixed wings to drive an energy-adjustable rotary-wing aircraft. It includes a rotating curtain, a second reducer 6, a motor 7, a rotating shaft 8, a fuselage frame 10 and a fixed wing 11. The fuselage frame 10 is symmetrically arranged with two rotating shafts 8 on both sides. Both are perpendicular to the longitudinal plane of symmetry of the aircraft, and the two motors 7 arranged on the fuselage frame 10 respectively drive the two rotating shafts 8 to rotate continuously after being decelerated by the two second reducers 6 arranged on the fuselage frame 10 respectively. Two rotating curtain wings are respectively fixedly connected on two rotating shafts 8; the rotating curtain wing comprises a rotating frame 1, and a curtain wing installed in the rotating frame 1, and the curtain wing comprises ...

Abstract

The invention discloses a driving energy-adjustable rotary wing aircraft with a fixed wing, wherein the aircraft is characterized by comprising rotary curtain wings, rotary shafts, speed reducers, motors, a fuselage frame and the fixed wings; the two rotary shafts are symmetrically arranged on the two sides of the fuselage frame, and the axis directions of the two rotary shafts are both perpendicular to the longitudinal symmetry plane of the aircraft; the two motors arranged on the fuselage frame are decelerated through the two speed reducers arranged on the fuselage frame respectively and then drive the two rotary shafts to rotate continuously; the two rotary curtain wings are fixedly connected to the two rotary shafts respectively, each rotary curtain wing comprises a rotary frame and a curtain wing body mounted in the rotary frame, and each curtain wing body comprises a curtain wing frame and soft curtain mounted on the curtain wing frame; and coil springs and driving motors are further arranged in the curtain wing frames and used for controlling the soft curtains to unfold and contract, and the fixed wing is arranged on the fuselage frame and used for generating lift force.

Description

technical field [0001] The invention relates to the field of movable-wing aircraft and flying robots, in particular to an energy-adjustable rotary-wing aircraft driven by two curtains with fixed wings. Background technique [0002] There are three flight types of aircraft: fixed wing, rotary wing and flapping wing, both of which are movable wings. [0003] Flapping wing flight is a flying method adopted by flying creatures in nature. It mainly uses the up and down flapping of the wings to generate lift and thrust at the same time. Flexibility, more suitable for performing flights around obstacles etc. For small-sized and low-speed aircraft flying under low Reynolds numbers, the unsteady lift generated by the flapping wing is much greater than the constant lift of the fixed wing; from the perspective of thrust, the propulsion efficiency of the flapping wing is higher than that of the propeller. At present, the research of flapping-wing aircraft mainly focuses on designing v...
