Abstract

To provide the government with independent control-system design, handling qualities analysis, and simulation research capabilities in support of Future Vertical Lift, the U.S. Army Combat Capabilities Development Command Aviation & Missile Center has developed generic high-fidelity flight-dynamics models of several advanced high-speed rotorcraft configurations including a tiltrotor. Full-flight envelope explicit model following control laws were designed for the generic tiltrotor using a multiobjective optimization approach to meet a comprehensive set of stability, handling qualities, and performance specifications. Helicopter response types were used for hover/low-speed, while typical fixed-wing response types (normal acceleration and sideslip command) were used at high speed. The control laws were evaluated in a piloted simulation experiment at the NASA Ames Vertical Motion Simulator using a series of previously developed high-speed handling qualities demonstration maneuvers. This paper discusses the control laws and the results of the piloted handling qualities assessment which show overall assigned Level 1 handling qualities in high-speed and Level 2 in transition.

倾转旋翼飞行控制设计与高速操纵品质评估

为了向政府提供独立的控制系统设计、操纵质量分析和模拟研究能力，以支持未来垂直升力，美国陆军作战能力发展司令部航空与导弹中心开发了几种先进高速旋翼机配置的通用高保真飞行动力学模型，其中包括倾转旋翼机。采用多目标优化方法，设计了通用倾转旋翼的全飞行包络线显式控制律模型，以满足综合的稳定性、操纵品质和性能要求。直升机响应类型用于悬停/低速，而典型的固定翼响应类型(正常加速和侧滑命令)用于高速。在NASA艾姆斯垂直运动模拟器上，通过一系列先前开发的高速操纵质量演示演习，对控制规律进行了评估。本文讨论了控制规律和操纵质量评价的结果，表明在高速状态下总体分配了一级操纵质量，在过渡状态下总体分配了二级操纵质量。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
