In response to Phase 3 of Contract F33615-70-C-1052, the necessary methodology has been developed to provide an independent analysis capability to Air Force Studies Analysis (AFSA) for accurately simulating the flight paths of single main rotor helicopters. The equations developed under Phase I of this contract have been generalized to represent other single main rotor helicopters that are currently operational and those designed for the near future. This report reviews the necessary equations for the determination of power required in accelerated flight and a method for determining the input coefficients based on the helicopter's physical parameters and power required in one g flight. The impact of the type of rotor system on the maximum thrust which can be produced is examined in light of the available flight test data. The concepts of energy maneuverability for a helicopter are examined using the AH-1G helicopter as an example. Several applications of these equations are considered including terrain following, decelerating turns, and low speed maneuvering.
