UAV systems are currently utilized in different applications ranging from aerial photography of agriculture, fire services, gas and oil pipelines to aerial targets for military training. Qinetiq Target Systems (QTS) manufactures unmanned air, land, and surface vehicles for Canadian Department of National Defence (DND) and international military customers. QTS is located at Medicine Hat, Alberta, and is interested in improving the performance of a UAV helicopter for the Canadian Department of National Defence and also international military customers. This UAV provides an unmanned air target for live-fire training, weapon system test, and evaluation of Canadian forces.This collaborative project will characterize the aerodynamic performance of the current rotor blade by wind tunnel testing at the University of Alberta. The project also investigates application of piezoelectric actuators for control of dynamic stall over the retreading rotor blade through wind tunnel testing. The project will also increase wind-tunnel testing capabilities in Western Canada for development of UAV.

无人机系统目前用于不同的应用，从农业、消防、天然气和石油管道的航空摄影到军事训练的空中目标。Qinetiq Target Systems（QTS）为加拿大国防部（DND）和国际军事客户生产无人驾驶空中、陆地和水面车辆。QTS位于阿尔伯塔的梅迪辛哈特，并有兴趣为加拿大国防部和国际军事客户改进无人机直升机的性能。这款无人机为加拿大部队的实弹训练、武器系统测试和评估提供了一个无人空中靶，这一合作项目将通过在阿尔伯塔大学进行的风洞测试来表征当前旋翼桨叶的空气动力性能。本计画亦借由风洞实验，探讨压电作动器在翻新旋翼桨叶动态失速控制上的应用。该项目还将提高加拿大西部开发无人机的风洞测试能力。
