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.

航空航天行业中电动推进器的使用正在迅速增长。由于它们的尺寸很小，电动推进器通常被组装在称为分布式电动推进（DEP）系统的阵列中。 DEP系统可以通过航空螺旋螺旋耦合提供推进的必需推力，并改善车辆空气动力学。电动螺旋桨的更快响应时间也可以用于推力矢量和操纵车辆。拟议的研究项目是根据无人车辆应用Dynamics Inc.与艾伯塔大学之间的合作伙伴关系开发的，可评估DEP的性能和功效无人驾驶汽车（UAV）上的系统。我们将对配备模块化DEP系统的无人机机翼的风洞模型进行实验研究。 DEP系统的位置和速度对机翼DEP组合总体性能的影响将受到审查。调查还将评估DEP系统对车辆进行操作的使用。最后，我们将使用称为粒子图像速度法的流量测量技术获得对空气峰耦合的基本理解。该项目的最终结果是针对无人机更高效且具有更长飞行范围的一套设计指南。这可以帮助使用无人机的各种应用程序，包括但不限于采矿，野火监控和执法。该项目中获得的知识和技术将有助于加拿大航空航天行业的发展。
