Abstract

The development of a rigid yet light-weight composite MAV wing is presented in this work. A grid based construction was opted for the fabrication of the wing. The distribution of the grids, their size and the number of composite plies were arrived based on a finite element based structural analysis of the wing. The aerodynamic loads acting on the wing structure were estimated using CFD simulations. The CFD computations were carried out using a multi-block structured RANS code based on an implicit finite volume algorithm to solve the time averaged Navier-Stokes equation. Based on the computational results, two light-weight MAV wings were fabricated having very high flexural stiffness. One was based on a sandwich type construction and the other was a planar grid construction.
