Zusammenfassung:
An appropriate design of the propulsion system for micro helicopters is an important task since most of the power on the helicopter is used for propulsion. While it is common to optimize the rotor aerodynamics, the drive train is mostly neglected. This is not sufficient for the rotor design, since it is not guaranteed that the electro motor can drive the rotor at its optimal point. Thus it is crucial to include the drive train in the simulation. This is done by using numerical Blade Element Momentum Theory (BEMT) for aerodynamic simulation which is extended by the drive train equation for truthful simulations. The new code is then used to investigate different rotor blade parameters on the drive train on the muFly helicopter. The results show that for the given drive train a thin blade with moderate camber, strong taper and twist performs best in turns of thrust to electrical power ratio.
