摘要
直升机风洞试验是高转速、高难度、高风险的动态试验,人工操控具有效率低、安全性差、劳动强度大等缺点。为了克服人工操控的缺陷,构建了基于网络通信的试验管理系统和软硬结合的多重安全保护措施,在此基础上形成了成熟的直升机风洞试验自动配平技术。目前这些技术已成功应用于直升机风洞试验控制,应用效果表明旋翼的智能控制技术具有结构灵活、操作方便、安全可靠、数据质量好、试验效率高等特点,大大提升了直升机风洞试验的控制水平,充分满足了直升机风洞试验的需求。
Helicopter wind tunnel tests are of high.speed,high-difficulty and high-risk. But manual operation in helicopter wind tunnel tests suffer low efficiency,poor security and high labor intensity. In order to solve these problems,we develop the test management system based on network data interaction and construct the triple safety protection system with combination of soft and hard ware. Further,the helicopter automatic trim system based on fuzzy control theory has been implemented. The intelligent control technology has been successfully applied to helicopter wind tunnel tests. The results show that the intelligent test system has advantages including flexible structure,convenient operation,high safety and reliability,good data quality and high test efficiency.
