Book Description
A new method is presented for calculating the quasi-steady transonic flow over a lifting or non-lifting rotor blade in both hover and forward flight by using Euler equations. The approach is to solve Euler equations in a rotor-fixed frame of reference using a finite volume method. A computer program was developed and was then verified by comparison with wind-tunnel data. In all cases considered, good agreement was found with published experimental data. Chang, I-Chung Ames Research Center RTOP 505-61-51...

Book Description
This paper demonstrates the current and future potential of finite potential of finite-difference methods for solving real rotor problems now rely largely on empiricism. The demonstration consists of a simple means of combining existing finite-difference, integral, and comprehensive loads codes to predict real transonic rotor flows. These computations are performed for hover and high-advance-ratio flight. Comparisons are made with experimental pressure data. Additional keywords: Helicopters; Equations of motion. (Author).
