摘要：
This paper deals with the calculation and measurement of aerodynamic characteristics in the hover of a radio-controlled helicopter. After a brief introduction of the efficiency and adaptation conditions of the rotors, the article focuses on the determination of the power envelope and specific power of the helicopter propulsion unit. The main purpose is to familiarize the reader with the calculation of the energy intensity of the helicopter in the hover and its verification by laboratory measurement. The calculation is done by using the ideal propulsion theory and simplified blade element theory. The final discussion focuses on the determination of the energy performance of a helicopter in a hover.
