Two Methods of Prediction of Hovering Performance

Abstract

The report presents two methods of prediction on the hovering performance of single-rotor helicopters. A generalized equation was formulated by the use of numerical and empirical techniques from flight test data for the prediction of hovering performance. This generalized equation leads to two methods of prediction: the Generalized Method and the Two-Point Method. Both of these methods of prediction are simple and easy to apply, and require only limited flight data information to predict the entire range of hovering performance. The accuracy of these methods falls within 5% of the flight data. Specific working examples and procedures are given.
