چکیده

A lightweight flapping-wing micro air vehicle (MAV) was designed and built and successfully filed in the sky. The unsteady aerodynamics associated with this MAV was detailedly studied by using the method of computational fluid dynamics (CFD).The variations of different parameters of the flapping MAV, such as flapping amplitude, pitch amplitude and flapping frequency, were investigated with numerical simulation. The Fluid-Structure coupling mechanics for flexible flapping-wings were subsequently researched and discussed. According to the practically developed MAV, a 2-D model for flexible flapping-wings was established. Fluid-Solid interaction deformation and its effects on the aero dynamic performance were analyzed, which offers a theoretical basis for design of the aircraft with flexible flapping-wing. The results of numerical simulation for the rigid and flexible flapping-wings were finally verified by conduct the aerodynamic performance tests in a low turbulence and low Reynolds number wind tunnel.

NUMERICAL ANALYSIS OF MAVs FLAPPING WINGS IN UNSTEADY CONDITIONS

Today, Flapping Micro Aerial Vehicles (MAV) are used in many different applications. Reynolds Number for this kind of aerial vehicle is about 104 ~ 105 which shows dominancy of inertial effects in comparison of viscous effects in flow field except adjacent of the solid boundaries. Due to periodic flapping stroke, fluid flow is unsteady. In addition, these creatures have some complexities in kin...

Smart flapping wing using Macro-Fiber Composite actuators

In the present study, we have developed a smart flapping wing with a MFC (macro-fiber composites) actuator. To mimic the flying mechanisms of nature’s flyers such as birds or insects, the aerodynamic characteristics related to the birds and ornithopters are investigated. To measure the aerodynamic forces of flapping devices, a test stand consisting of two loadcells is manufactured, and the dyna...

Loading Estimation of Flapping Wings under Aeroelastic Effect Using Finite Element Method

The aim of this paper is to provide an aeroelastic computational tool which determines the induced wing loads during flapping flight. For this purpose, a Finite Element (FE) code based on a four-node plate bending element formulation is developed to simulate the aeroelastic behavior of flapping wings in low incompressible flow. A quasi-steady aerodynamic model is incorporated into the aeroelast...

The Scalable Design of Flapping Micro-Air Vehicles Inspired by Insect Flight

Here we explain how flapping micro air vehicles (MAVs) can be designed at different scales, from bird to insect size. The common believe is that micro fixed wing airplanes and helicopters outperform MAVs at bird scale, but become inferior to flapping MAVs at the scale of insects as small as fruit flies. Here we present our experience with designing and building micro flapping air vehicles that ...

Flapping Wing Air Vehicles at Kaist

The flapping wing flight has superior maneuverability and aerodynamic advantages in a low Reynolds number regime. Nature’s flyers generate aerodynamic forces and moments from the various wing motions such as flapping and pitching to fly and sustain its flight stability. Bioinspired design of flapping air vehicle is one of the effective ways to exploit such a complex system. However the flapping...
