<p>The contra-rotating rotors are applied to UAVs because of the counter balance of the torque. High thrust can be obtained for the contra-rotating rotors, and its thrust can be increased by adopting a duct with a bellmouse. Therefore, we started the research of the large scale ducted fan having the contra-rotating rotors. The numerical analysis result is validated by the experimental result using a thrust measurement apparatus in this paper. Furthermore, research and development results of the contra-rotating ducted fan based on the numerical analysis are presented.</p>
