Description
Technical Field
The invention relates to the field of movable wing aircrafts and flying robots, in particular to an automatic curtain-drawing driving energy-adjustable high-efficiency flying flapping wing device.
Background
The flight mode of the aircraft comprises three flight modes of a fixed wing, a rotor wing and a flapping wing, wherein the flapping wing flight is a flight mode adopted by natural flight organisms, the upper flapping and the lower flapping of double wings are mainly utilized to simultaneously generate lift force and thrust force, and the flight mode has the main characteristic that the lifting, hovering and propelling functions are integrated, meanwhile, the flight mode has strong maneuverability and flexibility, and is more suitable for executing flight around obstacles and the like. For an aircraft in a small-size and low-speed flight state, the aircraft flies at a low Reynolds number, and the unsteady lift force generated by the flapping wings is much larger than the unsteady lift force of the fixed wings; from the thrust aspect, the flapping wing propulsion efficiency is higher than the propeller propulsion efficiency.
At present, the research of the flapping wing air vehicle mainly focuses on simulating the flight attitude of flying organisms in the nature and designing various flapping wing mechanisms. The flapping wing driving mechanism can be divided into a multi-degree-of-freedom flapping wing driving mechanism and a single-degree-of-freedom flapping wing driving mechanism, the multi-degree-of-freedom flapping wing driving mechanism can realize a complex motion form, but the mechanism is relatively large and complex, the single-degree-of-freedom flapping wing driving mechanism only needs to realize flapping motion, and the trailing edge of the fixed wing forms an attack angle which changes along with the flapping of the wing to realize the twisting motion.
However, the common problem of these flapping wing mechanisms is that the overall aerodynamic efficiency is low, even lower than that of the fixed wing micro-aircraft of the same scale. The main reason for the low overall efficiency of the flapping wing aircraft is that most of the existing researches simply imitate the appearance and flapping motion of wings of birds or insects, but the problems that the air resistance is reduced and unsteady aerodynamic force is generated by utilizing the change of the self posture and the structure of the wings in the process of flapping the flapping wings of flying organisms up and down are difficult to realize, and the generated problem of low aerodynamic efficiency seriously restricts the popularization and the application of the flapping wing aircraft.

The working principle of the invention is as follows: the flapping wing device utilizes an automatic curtain-drawing driving energy-adjustable high-efficiency flying flapping wing device to reduce the air resistance of a linearly reciprocating flapping wing in the resetting process, thereby improving the pneumatic efficiency of the flapping wing, and achieving the purpose of controlling lift force and thrust by adjusting the inclination angle of the flapping wing, namely, after a motor is started, a transmission shaft and a crank are driven to rotate after being decelerated by a third speed reducer, thereby driving a curtain wing frame connected on a connecting rod to do reciprocating translation, when the curtain wing frame moves close to the transmission shaft, the curtain wing frame is in a working state, at the moment, a driving motor does not work, a soft curtain is drawn to the maximum area under the action of a coil spring, so that the windward side of the soft curtain is opposite to airflow, the windward side of the soft curtain is vertical to the movement direction of the airflow, the airflow directly acts on the windward side of the soft curtain to obtain the maximum driving force, and simultaneously, the stepping motor drives the curtain wing frame to rotate after being decelerated by the second speed reducer, so as to change the inclination angle of the curtain wing, the positive pressure of airflow acting on the windward side of the soft curtain can be decomposed into lift force and thrust force, and the change of the inclination angle of the curtain wings can adjust the magnitude of the lift force and the thrust force; when the curtain wing frame moves away from the transmission shaft, the curtain wing frame is in a reset state, the driving motor starts to work at the moment, the soft curtain starts to contract under the action of the rotating wheel shaft, the soft curtain is wound on the rotating wheel shaft, and airflow directly flows out from the curtain wing frame, so that the air resistance borne by the soft curtain in the reset process is minimum, and the energy utilization efficiency in the reciprocating translation process is high; when the reset stroke is finished, the acting force of the airflow is reduced, the driving motor works in the reverse direction, and due to the action of the coil spring, the soft curtain is stretched to the largest area and is driven to be converted into a working state. Compared with the prior art, the invention has the following remarkable advantages:
1. according to the automatic curtain-pulling driving energy-adjustable high-efficiency flying flapping wing device, the linearly-moving curtain wings are linearly translated, the soft curtain controlled by the driving motor is designed, the soft curtain moves with the largest area facing the wind in the working stroke, the surface obtains larger and evenly-distributed pressure, the thrust in the working stroke is large and stable, and the area facing the wind is variable in the working state of the curtain wings, so that the driving energy is adjustable; the soft curtain starts to shrink under the action of the rotating wheel shaft in the reset stroke, so that the soft curtain is wound on the rotating wheel shaft, airflow directly flows out of the curtain wing frame, the acting area of wind power is small, the reset resistance of the curtain wings is minimum, and the aim of greatly improving the pneumatic efficiency of the curtain wings is fulfilled.
