The use of electrically driven propulsors in the aerospace industry is rapidly growing. Due to their small size, electrically driven propulsors are often assembled in an array known as a distributed electric propulsion (DEP) system. The DEP system can provide the required thrust for propulsion and improve vehicle aerodynamics through aero-propulsion coupling. The faster response-time of electric propellers can also be used for thrust vectoring and maneuvering the vehicle.The proposed research project, developed from the partnership between Unmanned Vehicle Applied Dynamics Inc. and the University of Alberta, evaluates the performance and efficacy of a DEP system on an unmanned aerial vehicle (UAV). We will perform an experimental study on a wind tunnel model of a UAV wing equipped with a modular DEP system. The effect of the location and speed of the DEP system on the overall performance of the wing-DEP combination will be scrutinized. The investigation will also evaluate the use of the DEP system for maneuvering the vehicle. Lastly, we will obtain a fundamental understanding of the aero-propulsive coupling using a flow measurement technique known as particle image velocimetry. The final outcome of this project is a set of design guidelines for UAVs that are more efficient and have a longer flight range. This can help various applications that use UAVs including, but not limited to mining, wildfire monitoring, and law enforcement. The knowledge gained and the technology developed in this project will contribute to the growth of the Canadian aerospace industry.

电力驱动推进器在航空航天工业中的使用正在迅速增长。由于尺寸较小，电力驱动推进器通常组装成阵列，称为分布式电力推进 (DEP) 系统。 DEP系统可以提供推进所需的推力，并通过空气推进耦合改善车辆的空气动力学性能。电动螺旋桨响应时间更快，还可用于推力矢量和车辆操纵。拟议的研究项目由无人驾驶车辆应用动力学公司和阿尔伯塔大学合作开发，评估 DEP 的性能和功效无人机（UAV）上的系统。我们将对配备模块化 DEP 系统的无人机机翼风洞模型进行实验研究。 DEP 系统的位置和速度对机翼-DEP 组合整体性能的影响将受到仔细审查。调查还将评估 DEP 系统在车辆操纵方面的使用情况。最后，我们将使用称为粒子图像测速的流量测量技术来获得对空气推进耦合的基本了解。该项目的最终成果是一套更高效、航程更长的无人机设计指南。这可以帮助使用无人机的各种应用，包括但不限于采矿、野火监测和执法。该项目中获得的知识和开发的技术将有助于加拿大航空航天业的发展。
