ABSTRACT
The design, the CFD numerical calculation, modeling of flight dynamics, the
calculation of the trim, the airframe manufacturing and flight test of a Dual Rotor
Micro Aerial Vehicle which can hover is studied in this paper.
According to the target of the design, using an equation for estimating the the
weight of MAV, and the method of aircraft design plete the
a 3D model in CATIA. Numerical simulation of flow-field around Dual Rotor MAV is
completed by using 3D2MUFS solver which is developed by MAV Center of Nanjing
University of Aeronautics and Astronautics.
The aerodynamic characteristic of micro propeller with low Reynolds numbers is
studied in this paper. In order pute the micro propeller aerodynamics
approximately, a revised theory bination of momentum theory and the blade
element approach is applied. The theory has been used to establish the mathematical
model of the rotor.
The mathematical model of Dual Rotor MAV is built, anda model used for
simlulation isbuilt in the Matlab/Simulik simulation environment, then some analysis
work is done to a unmanned tilt-rotor aircraft with the model ,so that we know much
characteristic of the unmanned tilt rotor aircraft.
Finally, the structure and part design of the Dual Rotor MAV is done in CATIA,
the prototype of the Dual Ro
