摘要本文报道的研究旨在发展一种度量标准，以量化和预测飞行员控制补偿的程度，飞行范围广泛的使命任务要素。要做到这一点，一系列的时域和频域的措施，以检查飞行员的控制活动，而飞行悬停/低速和向前飞行任务的效用进行了探讨。这些任务由两名试飞员使用加拿大国家研究理事会的贝尔412先进系统研究飞机和利物浦大学的HELIFLIGHT-R模拟器完成。对每一项任务进行了操纵品质评定，并与新开发的基于离散驾驶员输入的加权自适应控制补偿度量进行了比较，显示出良好的相关性。此外，结合随时间变化的频域曝光，所提出的度量被证明是有用的了解飞行员的主观评估，测量的控制活动和任务性能之间的关系。通过整理不同使命任务要素的主观和客观指标的结果，提出补偿边界来预测和验证库珀-哈珀操纵品质评定量表的主观评估。
Abstract The research reported in this paper is aimed at the development of a metric to quantify and predict the extent of pilot control compensation required to fly a wide range of mission task elements. To do this, the utility of a range of time- and frequency-domain measures to examine pilot control activity whilst flying hover/low-speed and forward flight tasks are explored. The tasks were performed by two test pilots using both the National Research Council (Canada)’s Bell 412 Advanced Systems Research Aircraft and the University of Liverpool’s HELIFLIGHT-R simulator. Handling qualities ratings were awarded for each of the tasks and compared with a newly developed weighted adaptive control compensation metric based on discrete pilot inputs, showing good correlation. Moreover, in combination with a time-varying frequency-domain exposure, the proposed metric is shown to be useful for understanding the relationship between the pilot’s subjective assessment, measured control activity and task performance. By collating the results from the subjective and objective metrics for a range of different mission task elements, compensation boundaries are proposed to predict and verify the subjective assessments from the Cooper-Harper Handling Qualities Rating scale.
