Rotorcraft is vulnerable to rotor-blade in-flight icing. As so far only large helicopter may have rotor blades de-iced by means of high-energy electro-thermal systems, whereas small helicopter is lacking in the electrical power required to run them. That is why Bell Helicopter Textron, a manufacturer of small rotorcraft, realized at University of Quebec at Chicoutimi (UQAC) between 2006 and 2014 two CRSNG-CRIAQ projects, in which three approaches were evaluated in simulated icing tests and demonstrated practical for rotorcraft application. These were then recommended for further investigation at higher TRL: as energy-wise technologies, low-ice-adhesion coatings and piezoelectric actuators, and as solution avoiding slips rings the low-weight mast-mounted generator (MMG). The project consists of developing in laboratory up to TRL level 5, the three technologies previously demonstrated feasible at TRL 3, or a combination thereof: ice-phobic coatings poised to reduce ice adhesion, but requiring high erosion resistance (Objective 1), efficient piezoelectric system equipped with resistant piezo-elements to ensure a durable anti-icing blade protection (Objective 2); and for MMG technology a wireless system for efficiently controlling the rotor blade heating (Objective 3). The project includes two fundamental works : the development of a new software for modelling the heat transfer on rotorcraft blades during de-icing (objective 4) and the continuation of the previous work on a physic-based model elaborated on ice adhesion (objective 5). The grant proposal will involve three Canadian industrial partners, Bell Helicopter Textron Canada, MagChem Inc. Canada, and Iders Canada; and four institutional partners: Anti-Icing Materials Laboratory of UQAC, National Research Council Aerospace, Ecole Polytechnique de Montreal and Ecole de Technologie Superieure. Three graduate students, two Ph. D. and a Master degree, will be involved in Objectives 2, 3 and 4. Given the present state of knowledge and scientific advancement, the full development of a durable ice-phobic coating or/and a reliable piezo-equipped system will constitute a breakdown, which will profit to all Canadian partners.

旋翼机易受旋翼桨叶空中结冰的影响。到目前为止，只有大型直升机可以通过高能电热系统对旋翼桨叶进行除冰，而小型直升机缺乏运行它们所需的电力。这就是为什么小型旋翼机制造商Bell Helicopter Textron在2006年至2014年期间在魁北克大学希库蒂米分校（UQAC）实现了两个CRSNG-CRIAQ项目，其中三种方法在模拟结冰测试中进行了评估，并证明了旋翼机应用的实用性。然后建议在更高的TRL下进行进一步研究：作为节能技术，低冰粘附涂层和压电致动器，以及作为避免滑环的解决方案，低重量桅杆安装发电机（MMG）。该项目包括在实验室中开发TRL 5级，之前在TRL 3中证明可行的三种技术，或它们的组合：防冰涂层准备减少冰粘附，但需要高耐腐蚀性（目标1）、高效的压电系统，配备耐压压电元件，以确保持久的防冰叶片保护（目标2）; MMG技术的无线系统，用于有效控制转子叶片加热（目标3）。该项目包括两项基本工作：开发一个新的软件，用于模拟除冰期间旋翼机叶片上的热传递（目标4），以及继续以前关于冰附着力的物理模型的工作（目标5）。 该赠款提案将涉及三个加拿大工业合作伙伴，贝尔直升机德事隆加拿大，MagChem公司。加拿大Iders Canada和四个机构伙伴：UQAC防冰材料实验室、国家航空航天研究理事会、蒙特利尔理工学院和蒙特利尔理工学院。三个研究生，两个博士。和硕士学位，将涉及目标2，3和4。鉴于目前的知识和科学进步状况，全面开发耐用的防冰涂层或/和可靠的压电系统将构成一个崩溃，这将使所有加拿大合作伙伴受益。
