Adaptation of Main Rotor of Small Helicopter at Different Altitudes

Abstract

This paper presents a discussion to some results of the calculation and measurement of aerodynamic characteristics of helicopter in the hover. A simple blade element model (BEM) is presented and a calculation of flight performance in a hover of helicopter Mikado LOGO 600 3D in various altitudes was performed as well. Results of the calculation are compared to the measurement conducted in the wind tunnel.
