Bionic hummingbird aircraft

Abstract

The invention discloses a bionic hummingbird aircraft; a high bionic design is adopted, the unsteady aerodynamics theory of hummingbird micro flapping-wing flight is explored, and a simplified model for realizing the movement law of a vertical take-off and landing and hovering flapping wing aircraft is established. An ultra-light flapping-wing structure based on a five-link crank rocker and an ultra-light flapping wing attack angle adjusting structure with a principle similar to a helicopter variable pitch principle are designed. In accordance with a modular and integrated design concept, bionic hummingbird aircraft subsystems such as a power transmission system and a flight control electronic system are researched and developed, and a hummingbird flapping wing prototype vehicle capable ofrealizing switching of vertical takeoff and landing and hovering flat flight is completed. Based on the design idea of '' flying early and flying more'', an experimental method is used to optimize aniterative principled sample machine to realize flight maneuvers such as hovering and forward flying of the bionic hummingbird aircraft to achieve the performance requirements of flexible detection. In the future, the bionic hummingbird aircraft can realize multi-bird cluster detection, and complete the low-altitude domain reconnaissance missions in a whole combat area through collaborative control and a bird-flock-like intelligent algorithm.

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 ...
