Abstract:

The Generalized Rotor Performance GRP program is a computer program designed for calculating forward flight performance of a helicopter rotor system at a specific flight condition. It can be used to evaluate either an articulated or a hingeless single rotor system in forward flight or in a wind-tunnel test. The program was originally designed by the Sikorsky Aircraft Company and purchased by the United States Navy. The goals of this thesis were 1 to reinvestigate the theory and logic used in the program, 2 to add selected desirable features to the program, 3 to produce a much needed Users Manual, and 4 to run an analysis comparing the programs calculated results against manufacturers data. These goals were accomplished and the results of the analysis indicated that the program produces highly accurate results within the normal cruise range of a modern helicopter.
