Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] The bionic hummingbird aircraft of the present invention includes a main structure body 1, a wing assembly 2, a flapping wing changing angle of attack structure 3, a flapping wing flapping drive mechanism 4 and a flight control system 5, such as figure 1 shown.

[0030] The main structure 1 is an ultra-light structure printed with photosensitive resin, with a height of 15 cm, and has an upper support 101 for the main structure and a lower support 102 for the main structure. The two sides of the upper bracket 101 of the main structure and the lower bracket 102 of the main structure are designed with connecting lugs 105 with rectangular through holes. The variable angle of attack in structure 3 drives the connection among the three steering gears 301 to realize the fixing among the three. ,Such as figure 2 , image 3 shown. The top of the above-men...

Abstract

The invention discloses a bionic hummingbird aircraft, which adopts a highly bionic design, explores the theory of unsteady aerodynamics of the miniature hummingbird flapping wing flight, and establishes a simplified model of the motion law of the flapping wing aircraft that can realize vertical take-off and landing and hovering in the air. An ultra-light structure for adjusting the angle of attack of the flapping wing based on the five-link crank-rocker ultra-light flapping-wing mechanism and the principle of pitch adjustment similar to a helicopter is designed. According to the design concept of modularization and integration, various subsystems of the bionic hummingbird flapping wing aircraft including power transmission system and flight control electronic system have been developed, and the prototype hummingbird flapping wing aircraft that can realize vertical take-off and landing and hovering and level flight switching has been completed. production. Based on the design idea of ​​"flying early and flying more", the experimental method is used to optimize the iterative principle prototype to realize the flight maneuvers of the bionic hummingbird flapping wing aircraft such as hovering and forward flight, and meet the performance requirements of flexible investigation. In the future, the bionic hummingbird aircraft can realize multi-bird cluster reconnaissance, and complete low-airspace reconnaissance tasks in the entire combat area through collaborative control and imitation bird swarm intelligent algorithms.

Description

technical field [0001] The invention relates to the field of bionic robots, in particular to a bionic hummingbird aircraft. Background technique [0002] At present, the development of advanced bionic detection equipment is in full swing. In Western countries, there have been successful development and application examples of micro-flapping-wing aircraft. However, my country started late in this area, and related research is limited by servo technology and energy. Progress is slow. [0003] Micro Air Vehicle (MAV) is also called nano aircraft or micro-nano aircraft. A micro air vehicle is defined as an aircraft with a size of 15 cm that can fly and complete various detection tasks by its own capabilities. Micro air vehicle was developed in the 1990s, and its application technology has basically gone beyond the research scope of traditional aircraft design and aerodynamic technology. It is a challenge to traditional aviation technology. At the same time, its appearance also ...
