Validation of the Rotorcraft Flight Simulation Program (C81) Using Operational Loads Survey Flight Test Data.

Abstract

The Rotorcraft Flight Simulation Program C81 has been used to simulate several test points from the Operational Loads Survey Flight Test Program for an AH-1G helicopter in order to demonstrate program capabilities. The results of those simulations are summarized in this report. Measured and computed performance characteristics and main rotor bending moments and accelerations are compared for steady-state and maneuvering flight conditions. Computed main rotor aerodynamic quantities are compared with test data, in contour-plot form, for level flight conditions. This report also contains a brief description of the flight test program, a detailed description of the creation of the input decks used for the simulations, and a discussion of possible improvements for future test programs.
