A hybrid power source system and method for a flapping-wing bird-like aircraft

Abstract

The invention discloses a hybrid power source system for a bird-like flapping-wing air vehicle and a method for the hybrid power source system. The hybrid power source system comprises a lithium ion battery module, a flexible solar cell module, a lithium ion battery charge management module, a lithium ion battery voltage monitoring module and a lithium ion battery temperature monitoring module, wherein the lithium ion battery module is mounted inside a body of the bird-like flapping-wing air vehicle and supplies power to the bird-like flapping-wing air vehicle directly, the flexible solar cell module is mounted on the surface of the body of the bird-like flapping-wing air vehicle and used for charging a lithium ion battery, the lithium ion battery charge management module is capable of tracking maximum power voltage of solar cells, the lithium ion battery voltage monitoring module is capable of measuring voltage of the lithium ion battery accurately according to a Kelvin four-terminal sensing technology, and the lithium ion battery temperature monitoring module is capable of monitoring the temperature of the lithium ion battery in real time. The hybrid power source system has the advantage that flight endurance of the bird-like flapping-wing air vehicle can be improved effectively without increasing the weight of the power source system obviously.

Description

technical field [0001] The invention belongs to the interdisciplinary fields of robot science, material science and engineering, and particularly relates to a hybrid power source system and method of a flapping-wing bird-like aircraft. Background technique [0002] Due to its small size, light weight, low cost, good stealth and maneuverability, small take-off and landing space, low noise, and good concealment, small unmanned aerial vehicles have very important and extensive applications in both national defense and civilian fields. application. According to their different flight principles and layout methods, small unmanned aerial vehicles are divided into the following three categories: fixed-wing, rotary-wing and flapping-wing. The flapping wing bionic aircraft is a new concept small aircraft that imitates the flight of birds or insects. It generates lift and thrust through the movement of its wings. It belongs to the category of bionic robots and aircraft. There are so...
