Paper Abstract

The objective of this project is to develop a hovering Micro Aerial Vehicle (MAY) with MEMS microrotor technology. In this paper, we present a novel MEMS-based microrotor technology. The microrotor is only 14mm in diameter and could be used on a hovering MAy. And a special kind of MAY, a four-rotor micro rotorcraft, is described. The Reynolds number is very low in micro air vehicles, which lead to the aerodynamics of them being different from the traditional ones. In view of this, the aerodynamics of two-dimensional airfoil with very low Reynolds number is analyzed. A revised theory which combines of momentum theory and the blade element approach is applied to study the microrotor's aerodynamics. This paper also presents the design of software simulation system for hovering MAY. In particular, it is intended to estimate flight control algorithms and performance for the hovering MAY, a four-rotor micro rotorcraft. Moreover, a 3D virtual environment simulation is given as a visualization tool. Finally, we get a scheme of microrotor that is very thin, flat and trapezoidal. By using MEMS techniques, a microrotor with the theme that is only 14mm in diameter and could be drove by a 2mm electric magnetic micromotor is presented.
