Servo bat-wing aircraft

Abstract

The invention belongs to the field of aircraft design, and discloses a servo bat-wing aircraft which comprises a bat-wing aircraft body, a photovoltaic energy system, an intelligent obstacle avoidance and flight control system, a communication link system and a task load. The servo-type bat-wing aircraft can realize a task mode of long-term servo and intermittent reconnaissance, namely, the servo-type bat-wing aircraft is hidden on a roof in the daytime, collects energy by utilizing a photovoltaic energy system and reconnaissance is carried out on a specified area at night, so that the limitation of frequent recovery, charging and discharging of a traditional unmanned aerial vehicle is broken through; the flapping of the flexible bat wings during flight is higher in efficiency and lower in noise compared with a fixed wing and a rotor wing, and hidden reconnaissance is more facilitated; the intelligent obstacle avoidance and flight control system has the advantages of ultrasonic wave and infrared light distance measurement, and can assist the aircraft to complete night obstacle avoidance flight; the communication link system supports a Beidou satellite communication function, so that the instruction and image transmission of the aircraft is not limited by distance any more.

Description

technical field [0001] The invention belongs to the field of aircraft design, and in particular relates to a servo bat-wing aircraft. Background technique [0002] The existing flapping-wing aircraft has the advantages of low flight noise and strong concealment, and can be used for low-altitude reconnaissance. However, due to the limited capacity of the mounted battery, reconnaissance tasks can only be performed within a small radius centered on the ground station, and both release and recovery must rely on manual operations, and do not have the ability to obtain energy autonomously. Each reconnaissance mission After completion, it needs to be returned for charging and maintenance, which makes the ground support work more cumbersome. [0003] The Chinese patent application with publication number CN113002772A discloses a flap-integrated imitation bat flapping-wing aircraft, which uses a DC brushless motor unit as a driving mechanism, and reduces the rotational speed and inc...

Problems solved by technology

[0004] In addition, most of the existing flapping-wing aircraft are designed to imitate insects and birds, and their flight efficiency is relatively low, which is not conducive to prolonging the endurance time. They can only perform reconnaissance missions during the day, and cannot effectively identify them when flying at night. Surrounding obstacles, there is a greater flight safety hazard

Although some obstacle avoidance devices have been used, they are generally developed based on ultrasonic ranging technology or infrared ranging technology. Ultrasonic waves are not limited by visible light, and batwing aircraft will not be disturbed by propeller vibration, but the ranging accuracy is low. , the detection range is narrow, and it is greatly affected by windy weather; the infrared light ranging accuracy is high, and the range can reach tens of meters, but it cannot work in an environment where there is no visible light at all. Therefore, neither of the two ranging methods can achieve all-weather obstacle avoidance flight
