| Abstract: | A numerical procedure is presented for calculating the flowfield over a lifting and nonlifting rotor in hover.The approach is to solve the inviscid compressible Euler equations in a rotor fixed frame of refrence using a finite volume method and Runge Kutta scheme.Without any wake model,the pressure distributions are presented for two bladed rotor,the theoretical results show good agreement with experiment data. |
