直升机自适应桨叶模型的初步实验研究

为了研究压电陶瓷对复合材料模型的驱动性能，掌握其规律，为自适应旋翼的研究打下基础，文中模仿直升机桨叶设计了一个典型模型试件，利用压电陶瓷在不同布片方式下对其进行驱动，使其产生弯曲和扭转变形。不同条件下的对比实验表明，压电陶瓷作为驱动器可以达到比较好的驱动效果。

Experimental Research on Adaptive Rotor Blade Model of Helicopter

The adaptive control system of the helicopter rotor blade is an important technique in future advanced composite helicopter. It has a lot of advantages over traditional rotor blade because it controls the flight of the helicopter without blade pitch and swash plate. In this paper, a typical model which intimate the blade of helicopter is designed. Exciting the model with piezoceramic will result in a torsional deformation. The objective of this paper is to find the mechanical properties of the piezoceramic as an actuator. The result of the experiment will give some help for the further research work.
