A compressible Reynolds-averaged Navier–Stokes (RANS) solver is used to improve the design of a microscale shroud applicable for micro air vehicle (MAV) applications. The new shroud is primarily designed to improve the hover performance; however, it is also shaped to better suit nonhovering flight conditions. The proposed shroud design has an elliptic shape on the inner portion of the shroud inlet and a circular shape on the outer portion. A collective angle sweep study of the shrouded rotor configuration using the proposed shroud design shows significant performance benefits in hover.

Blade Geometry

<p>The development of physics based analysis to predict the hover performance of a micro rotor system meant for a hover capable micro air vehicle for studying the role of blade geometric parameters (such as planform, twist etc.) is discussed. The analysis is developed using blade element theory using lookup table for the sectional airfoil properties taken from literature. The rotor induced inflow is obtained using blade element momentum theory. The use of taper seems beneficial in improving the hover efficiency for lower values of thrust coefficient. For rotors operating at high thrust conditions, high negative twist is desirable. There is no unique blade geometry which performs well under all thrust conditions. This well validated analysis can be used for design of hover capable micro air vehicles.</p>
