The aerospace industry is facing political, social, and economic pressure to develop cleaner and lighter aircrafts**made from environmentally friendly materials and using energy efficient technologies. One key technology is the development of Electro-Mechanical Actuators (EMA) to replace conventional hydraulic actuators for flight control surfaces. The main issue in developing practical EMAs for flight control is reliability as traditional gears and screw mechanisms can seize and lead to catastrophic failures. A first NSERC-CRIAQ project (ENV404) demonstrated that MagnetoRheological **Fluid (MRF) rotary clutches for Continuous Slippage Actuation (CSA) can advantageously meet aerospace motion control requirements with their high control bandwidth, high power-to-weight ratios, and high reliability. The goal of this new NSERC-CRIAQ-CARIC project proposal (ENV709) is to provide the knowledge and understanding required to enable practical applications of MRF actuators for helicopter flight control applications. The most prominent remaining challenge is the **durability of MRF and the design of optimal clutches. The proposed research will conduct an in-depth experimental characterization of the degradation of MRF. Fluids will be analyzed and the degradation process identified and quantified. Based on findings, improved MRF and clutch designs will be proposed and verified. Condition monitoring strategies will be proposed and a MRF condition monitoring sensor technology will be developed. Finally, a fully functional MRF actuator will be prototyped for a typical flight control application and the actuator will be tested on a full-scale endurance test bench replicating flight test conditions. The research will advance the field of aerospace and robotics by providing the knowledge necessary to complete the development of a new promising actuation technology, MRF rotary clutches used in CSA. The**research will provide Canadian aerospace industry with proprietary new technology that will become a strategic**asset for Canada's competitiveness in the aerospace sector. **

航空航天业面临着政治、社会和经济压力，需要开发由环保材料和节能技术制成的更清洁、更轻的飞机**。一项关键技术是开发机电执行器 (EMA)，以取代飞行控制面的传统液压执行器。开发用于飞行控制的实用 EMA 的主要问题是可靠性，因为传统的齿轮和螺杆机构可能会卡住并导致灾难性故障。第一个 NSERC-CRIAQ 项目 (ENV404) 证明，用于连续滑动致动 (CSA) 的磁流变**流体 (MRF) 旋转离合器可以凭借其高控制带宽、高功率重量比和高可靠性。这个新的 NSERC-CRIAQ-CARIC 项目提案 (ENV709) 的目标是提供所需的知识和理解，以实现 MRF 执行器在直升机飞行控制应用中的实际应用。剩下的最突出的挑战是 MRF 的耐用性和最佳离合器的设计。拟议的研究将对 MRF 的降解进行深入的实验表征。将分析流体并识别和量化降解过程。根据调查结果，将提出并验证改进的 MRF 和离合器设计。将提出状态监测策略并开发磁流变状态监测传感器技术。最后，将针对典型的飞行控制应用制作功能齐全的 MRF 执行器原型，并将在复制飞行测试条件的全尺寸耐久性测试台上对执行器进行测试。该研究将提供完成开发一种有前景的新驱动技术（CSA 中使用的 MRF 旋转离合器）所需的知识，从而推动航空航天和机器人领域的发展。该**研究将为加拿大航空航天工业提供专有的新技术，该技术将成为加拿大在航空航天领域竞争力的战略**资产。 **
