Abstract:

The transport effectiveness evaluation of high-speed helicopters is studied by providing transport task profiles with practical needs. The X3 compound helicopter and V-22 tiltrotor aircraft are selected as the research objects. After selecting some typical mission profiles, flight performance parameters are calculated, mainly including the required power, range and fuel consumption rate. A high-speed helicopter transport effectiveness evaluation model is established, and the calculation results of the performance parameters of the flight profile are substituted into the model for effectiveness evaluation, and the factors affecting the effectiveness are analyzed. The sensitivity of the parameters is analyzed. Finally, the transport effectiveness between different aircraft configurations is compared and analyzed, and suitable aircraft configurations for different transport tasks are proposed. Suggestions for improving transport effectiveness are also given.

Key words: compound-helicopter, tiltrotor aircraft, aircraft overall performance, transport effectiveness evaluation, high-speed helicopter
