Description
Technical field
A kind of four axis flapping-wing aircrafts, belong to aircraft field, more particularly to a kind of four axis flapping-wing aircrafts.
Background technology
Flapping-wing aircraft is also known as ornithopter, refers to the aviation for overweighting air that wing can flutter up and down as bird and insect wing
Device, the wing fluttered not only produce lift, also produce forward motive force.Modern flapping wing aircraft is divided into imitative bird from principle and flutters
The wing and imitative insect flapping wing, based on the unmanned flapping wing of microminiature.The frequency of fluttering of imitative bird flapping wing is low, and wing area is big, and similar birds fly
OK, manufacture is relatively easy；Imitative insect flapping wing is fluttered, and frequency is high, and wing area is small, and manufacture difficulty is high, but can easily realize outstanding
Stop.Since the root of blade of existing flapping wing mechanism can not change the hinge of blade incidence, existing flapping wing mechanism can only
Using flexible blade, change the angle of attack by the deformation of blade in itself, the lift that flexible blade can produce is smaller, can not meet big
The requirement of lift.
