Helicopter Effectiveness Evaluation System Based on Simulator and Mission Simulation

目前直升机效能评估问题复杂,评估准确度和精度难以保障,针对这一问题,提出了将高精度直升机模拟器与仿真评估相结合的效能评估方法,并以直升机运输任务为例,结合人在环和人不在环两种评估模式,建立了直升机运输任务总体效能指标体系与分系统效能指标体系,梳理了效能评估流程,构建了包含直升机模拟器硬件平台和效能评估软件平台的直升机运输任务效能评估系统。以MI-26、AW-139、UH-60、MI-17和Hx直升机为例进行仿真,将结果数据与经典的对数法求解的结果数据对比,其效能排序结果一致,验证了效能评估系统的可行性与评估结果的可信性。对比了Hx直升机在人在环评估模式下的评估结果与人不在环评估模式下的结果,其结果数据较为接近,验证了人在环评估模式下的直升机效能评估系统的可行性和可信性。

The effectiveness evaluation of helicopter is rather complicated and the precision and accuracy of the evaluation can not be ensured. To solve this problem, a new effectiveness evaluation method combined with high-ac- curacy helicopter simulator and simulation evaluation method was presented in this paper. Besides, to illustrate this method, the transport mission was chosen as an example. This method combined the pilot-in-the-loop mode and the pilot-not-in-the-loop mode. In this method, index systems of helicopter transport Mission effectiveness and subsys- tem effectiveness were built to achieve a helicopter transport Mission effectiveness evaluation system. In this system, transport Mission progresses of different helicopters were simulated and the software platform was used to calculate the effectiveness value. To prove the availability of the evaluating system and the reliability of the evaluating result, the helicopters such as MI-26,AW-139, Black-Hawk, MI-17 and Hx were chosen to carry out the simulation experi- ment. The result data were compared with the result from the traditional logarithmic method and the sequences of re- sults accorded with each other. In the pilot-in-the-loop mode, the result data of Hx helicopter were compared with the result data in the pilot-not-in-the-loop mode and the data were nearly the same. This proves the availability and reliability of helicopter effectiveness evaluation system in the pilot-in-the-loop mode.
