摘要
直-8某型直升机在试飞过程中多次出现旋翼超转现象。针对此问题,从功率匹配和系统响应两方面进行研究,分析了旋翼超转产生的机理,提出了一种基于需用功率分布优化总距-油门关系的方法。试飞验证表明,该方法能够有效地解决旋翼超转问题。
Rotor overruns subjected to a type helicopter of Z8 appeared repeatedly in the process of flight, aiming at which power matching and system response were studied in this paper. By the mechanism of rotor overruns, a method was presented for identifying relationships of pitch -throttle based on power density required. Series of studies were carried out on the the results demonstrate that rotor overruns was greatly improved. analyzing collective fight and
