Zusammenfassung:
The AH-64 helicopter, currently powered by two GE-T700-701 engines, is being upgraded to -701C powerplants with increased perf omance and digital engine controls. This paper presents the validation of a helicopter flight simulation model, FLYRT, for investigations of engine/airframe compatibility. First, typical engine response and controllability issues that can be encountered are discussed. Then the basis of the FLYRT model is reviewed and pertinent details of the three engine types modeled in this study are presented. The capability of FLYRT to predict engine/ airframe dynamic response is validated through extensive correlation with aggressive autorotation recovery, unmask/remask, and roll reversal flight test maneuvers. Roll reversals require use of the blade element version of the rotor model in order to predict the high torque spike characteristic of this uncompensated maneuver. Having established FLYRT as a valid tool, response problems and proposed design solutions can now be readily investigated using FLYRT engine/ airframe simulations.
