Effect of Fluid-Structure Interaction on Noise Generation in MAV with Fixed and Flapping Membrane Wing

An experimental study on the effect of fluid-structure interaction on noise generation in Micro Air Vehicle (MAV) with fixed and flapping membrane Tipula sp. wing is investigated. The acoustic performance of the fixed and flapping wing which made up of certain characteristic thin materials such as L...
