Energetics of Windmill in Unmanned Aerial Vehicle (Experimental Investigations, Stalling Flow)

Abstract

The paper considers an environmental influence on working high speed mill as a component of vortex heat pump. Experimental investigations of small high speed mill have been carried out in the aerator mode. The paper has determined conditions when the high speed mill is acting as a heat pump. It has been shown that the high speed mill has a maximum transformation ratio not more than 3.5.
