Abstract

The invention discloses a bionic aircraft which realizes the conversion of a flapping rotor and a flapping wing flight mode based on a deformable wing, and belongs to the technical field of bionic aircraft design. When it is in vertical take-off, landing and hovering, it is a flapping rotor flight mode, and its structure is characterized by that the flapping wings on both sides are mounted in an axisymmetric manner, that is, the airfoils on both sides are antisymmetrical; When in forward flight or gliding, the flapping wing or fixed wing flight mode is characterized by symmetrical mounting ofthe flapping wing on both sides in a fixed wing symmetrical manner, i.e., symmetrical wing profiles on both sides. At that same time, an elastic bow beam is adopt, In the structural design of deformable wing rib composed of chord and multi-bar mechanism, when the shape of deformable wing is changed, by rotating the tie rod installed at the root of wing and the cable connecting each wing rib, the multi-bar mechanism is pulled to force the connected bow beam to produce the elastic deformation required, that is, the overall structure of the airfoil is kept unchanged, but the leading edge and thetrailing edge of the deformable wing are interchanged. The invention simplifies the driving mechanism and the integral configuration of the aircraft, and remarkably improves the aerodynamic efficiencyand the lift coefficient.

Description

technical field [0001] The invention relates to a bionic aircraft, in particular to a bionic aircraft which realizes the flight mode conversion between a flapping rotor and a flapping wing based on a deformable wing, and belongs to the technical field of bionic aircraft design. Background technique [0002] In the field of bionic aircraft design, researchers have been looking for an aircraft design scheme that enables bionic aircraft to have both high-efficiency vertical take-off and landing hovering and high-speed forward flight capabilities. Usually, the design scheme of bionic aircraft has two modes: (1) Aircraft imitating flying insects (such as flies) or imitating hummingbirds: this biomimetic aircraft adopts a flight mode that mainly flaps back and forth horizontally and reverses as an auxiliary Realize the flight performance of efficient vertical take-off and landing hovering; but when it is in the forward flight state, it is similar to a rotor, and its flight speed a...
