| Abstract: | The aerodynamic characteristics of coaxial rotors in hover state have been investigated. A vortex cylinder model is given to represent a single Joukowski rotor and two algebra formulas have been found to approximate the first and second kind of complete elliptical integrals. Then the whole vortex system of coaxial rotors is divided into a serious vortex cylinders. In addition, an experiment of the hovering aerodynamic characteristics of coaxial rotors has been conducted on the rotor test stand. By comparing the test results with the theoretical calculations, several important conclusions have been drawn. |
