Micro flapping-wing air vehicle experimental platform and flight data acquisition method based on the same

Abstract

The invention discloses a micro flapping-wing air vehicle experimental platform and a flight data acquisition method based on the same. The platform at least comprises a six-axis force sensor, a frequency meter, an oscilloscope and an upper compute. That measurable flight data include aerodynamic force, aerodynamic moment, flapping wing frequency and flapping wing power, which can meet the experimental requirements of a flapping wing type aircraft to the maximum extent and simulate a real flight state. The fixed bracket of the aircraft is designed as a mouth-shaped structure, which can be widely used in the flight test of micro flapping-wing aircraft with different sizes. The platform also comprises an attitude conversion joint, which can realize the multi-attitude experiment test of the micro flapping-wing aircraft. The fixed base of the invention supports three-degree-of-freedom position adjustment, and can realize multi-angle and multi-orientation adjustment of the photoelectric sensor.

Description

technical field [0001] The invention belongs to the technical fields of machinery, experimental measurement technology, data acquisition and processing, and in particular relates to an experimental platform for a miniature flapping-wing aircraft. Background technique [0002] In recent years, the research and development of micro-aircraft has attracted more and more attention from various countries. Micro-aircraft is considered to be an important reconnaissance and attack weapon on the future battlefield. Micro-aircraft equipped with corresponding sensors and communication equipment can also be widely used in civilian fields. Due to its high maneuverability, flexibility and low noise, the flapping-wing micro-aircraft has more advantages in low-altitude reconnaissance, terrain survey, disaster search and rescue, and has become a research hotspot in this field. [0003] Since the micro flapping wing aircraft is a relatively complex system, its research involves many aspects su...
