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.

航空航天行业面临政治，社会和经济压力，以开发清洁器和更轻的飞机 由环保材料制成，并使用节能技术。一项关键技术是开发电力力学执行器（EMA），以取代传统的液压执行器以进行飞行控制表面。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丝机制可以抓住并导致灾难性故障。第一个NSERC-CRIAQ项目（ENV404）证明了磁性 用于连续滑动致动（CSA）的流体（MRF）旋转离合器可以有利地满足航空航天运动控制要求，其高控制带宽，高功率重量比和高可靠性。这项新的NSERC-CRIAQ-CARICARIC项目建议（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程序中的实际应用。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降解进行深入的实验表征。流体将进行分析，并确定和量化降解过程。根据发现，将提出和验证改进的MRF和离合器设计。将提出条件监测策略，并将开发MRF状况监测传感器技术。最后，将对典型的飞行控制申请进行原型MRF执行器，并将在全面耐力测试台上进行测试，重复飞行测试条件。这项研究将通过提供开发新的有前途的驱动技术（MRF MRF旋转离合器）使用的知识来推动航空航天和机器人技术领域。这 研究将为加拿大航空业提供专有的新技术，这将成为战略 加拿大在航空航天部门的竞争力的资产。
