重ね合わせロータの性能評価数理モデルの構築と考察

抄録

Recently, rotorcrafts with various configurations have been developed, and some of them have partially overlapping rotors. The ratio of the distance between the rotor axes to the rotor radius of the partially overlapping rotors is close to 1, and the value is between those of tandem rotors and coaxial rotors. And the distance between the rotor planes in the partially overlapping rotors is much less than the rotor radius. A mathematical model for the overlapping rotors during hover has been newly established. By using the model, the aerodynamic performance of the overlapping rotors has been revealed with a parameter of the distance between the rotational axes.
