OPTIMAL GAP DISTANCE BETWEEN ROTORS OF MINI QUADROTOR HELICOPTER

摘要

This paper describes comparison between virtual simulation of rotors for flying platforms (mini UAV - Unmanned Aerial Vehicle) and real experiments. During virtual simulation there were conducted similar to real experiments with the use of scanned rotors (with 3D scanner) and same environment conditions. In quadrotor helicopter (quadrocopter) air flows that are going out from rotors and affecting each other were simulated with CFD (Computational Fluid Dynamics) software. Analysis of several helicopters that have different distances between rotors on different angular velocities were compared. Optimal gap distance between rotors is determined, when helicopter mass is minimum and rotors are creating maximum lifting force (minimum impact of air flows to each other).
