变稳直升机设计与应用技术

变稳直升机在直升机研制过程中发挥着至关重要的作用。通过回顾美国、加拿大、德国等航空强国各个阶段典型变稳直升机研制历程,系统性梳理了变稳直升机研制中所涉及的几项关键技术,如变稳能力分析、变稳安全策略、变稳控制方法以及可变人感系统等。在此基础上,参照国外研制经验提出了上述技术的设计原则和相关要求。同时,对变稳直升机在飞行品质标准研究、新技术演示验证及飞行员培训等方面的应用进行了简要分析。

Design and application technologies of variable stability helicopter

Variable stability helicopter plays an important role in the development of helicopter. This paper firstly introduced the development process and application of the typical variable stability helicopter in each stage of the powerful aviation nations such as the United States, Canada and Germany, and analyzed the key technologies such as variable stability capability estimation, the variable stability safety strategy, the variable stability control method and the variable artificial feel system, et al. Then, typical applications of variable stability helicopter were given briefly in three aspects like helicopter flight quality research, new technology demonstration and pilot training.
