Five distinct phases of flight testing are outlined: initial flight evaluation, engine-helicopter integration, intensive flying, environmental tests and continuation development after introduction of engines into service. Areas of evaluation are listed and ultimate objectives specified. Since many areas of flight evaluation are common with fixed wing subsonic aircraft, emphasis is laid primarily on matching of the engine characteristics to the helicopter dynamic system. The paper is concluded with a statement of prerequisites of “ideal” engines and their control systems for helicopters.
