A flapping-wing aircraft with twisted inner wings

Abstract

The invention provides a flapping wing aircraft capable of realizing twisting of inner wings. The flapping wing aircraft comprises a rack, wings, rear drive devices and front drive devices. The rack has mounting positions. The wings are symmetrically arranged on the both sides of the rack. The wing on each side comprises an inner wing main flapping rod and an inner wing auxiliary flapping rod. The inner wing main flapping rods generate lift required during the flapping wing flight process. The inner wing auxiliary flapping rods generate lift and thrust required during the flapping wing flight process. The front drive devices are mounted in the mounting positions of the rack at the front and used for driving the inner wing main flapping rods. The rear drive devices are mounted in the mounting positions of the rack at the rear and used for driving the inner wing auxiliary flapping rods. The inner wing main flapping rods and the inner wing auxiliary flapping rods on the both sides of the rack have phase differences. The flapping wing aircraft has the advantages that the design of front and rear inner wing flapping mechanisms having the phase differences is provided, the flapping wing motions which are in accordance with the flapping wing flight principle are conducted, and the takeoff, direct flight and landing functions can be fulfilled when the left and right wings are synchronized; and when differential motions are conducted, the functions such as pitching, yawing and steering under the asynchronous control of frequencies and amplitudes of the left and right flapping wings can be fulfilled.

Description

Technical field [0001] The invention relates to the technical field of aircraft, in particular to a flapping-wing aircraft with twisted inner wings. Background technique [0002] Bionic flapping-wing aircraft is an aircraft designed to simulate the flapping wing action of natural animals and achieve basic flight characteristics; compared to the research of fixed-wing and rotary-wing aircraft, flapping-wing aircraft is still in the exploratory stage. However, flapping-wing aircraft has been widely studied in the fields of national defense and civil use because of its advantages of high flight efficiency, low energy consumption, light weight, small size, low cost and good operability. [0003] The asymmetric flapping wing structure with single crank and double rocker designed by Northwestern Polytechnical University uses the left and right connecting rods to drive the rocker to control the flapping action of the wings on both sides that are not completely synchronized; the seven-bar ...
