悬停状态下旋翼模型桨叶气弹稳定性试验研究

详细介绍了旋翼桨叶气弹稳定性试验采用的试验模型，试验设备，试验状态和试验方法。重点论述了先进旋翼的结构形式，以及简单可靠的周期变矩激振方法。试验用液压作动简对自动倾斜器的不动环激振，共进行４６种状态结果，其结果符合要求，与理论分析结果有较好的一致性。该项试验的激振方法和数据采集处理技术可直接用于直升机型号研制中的旋翼气弹稳定性试验，为进一步发展我国旋翼气弹稳定性试验技术打下了良好的基础。

Experimental Investigation on Aeroelastical Stability of Model Rotor Blades in Hover

An aeroelastical stability experiment of model rotor blades was conducted in 1991 on the 2m Diameter Rotor Mode Test Facility. The model, equipment, test condition and method are introduced in detail. It puts emphasis on the structural model of advanced rotor, and the simple and reliable method of excitation. The results of the experiment are in accordance with the theoretical analysis. The method of excitation and the technology of data acquisition and processing can be used directly in the development of helicopters.
