A major focus of the applicant's research program in the recent years has been the development of a realistic structural and dynamic model of a smart helicopter rotor blade that can be used to simulate dynamic behaviour of these blades with a high degree of fidelity. A continuous model of a smart rotor blade, without initial span-wise twist, was developed in the previous phase of this research program. This model that incorporates integrated piezoelectric fibres as Macro Fibre Composites (MFC) can be used to investigate the controllability of undesirable dynamic responses by using the piezoelectric actuators to influence the dynamic response of the blades. Building on the developments of the previous phase of this research program, the next phase will include the following objectives:

近年来，申请人的研究计划的主要焦点是开发智能直升机旋翼桨叶的现实结构和动态模型，该模型可以用于以高度的保真度模拟这些桨叶的动态行为。在本研究计划的前一阶段，开发了一个没有初始展向扭转的智能转子叶片的连续模型。该模型采用集成压电纤维作为宏纤维复合材料（MFC），可用于研究不期望的动态响应的可控性，通过使用压电致动器来影响叶片的动态响应。在本研究计划前一阶段发展的基础上，下一阶段将包括以下目标：
