| Abstract: |
| Recently the study of deformations for insect wings has become a hotspot while few people attended the deformation of flapping-wing aerial vehicles. But it is existed when insects, birds and flapping-wing aerial vehicles fly, it must be considered to calculate the aerodynamics accurately. This paper compared the inertial force and aerodynamics of membrane flapping-wing aerial vehicles in one cycle, and found their ratio is about 2. Then the boundary condition of fixed support in body-fixed coordinate system was put forward, the finite element method was used to calculate the deformations respectively that caused by inertial force and aerodynamics. A conclusion can be found that the deformation caused by the aerodynamics should not be overlooked. The maximum positive deformation caused by the composition of inertial forces and aerodynamics occurs at the start phase of downstroke, and the maximum negative deformation occurs in the start phase of upstroke. The paper provides a foundation of mechanic analysis for the design of membrane flapping-wing aerial vehicles. |
