Advanced rotor analysis method for the next-generation small multirotor aerial vehicle

所提出的研究的目的是开发一个转子的设计和分析方法，适用于小型多旋翼飞行器，如四轴飞行器。随后的方法将导致旋翼系统具有改进的飞行性能，例如耐久性或高速飞行特性。虽然多旋翼飞行器经常被选择作为遥感平台，因为它们在悬停时相对容易控制，但在高速或机动飞行期间，控制变得复杂。可靠的飞行控制的挑战是由于典型的小尺度的非线性空气动力响应和由于几个转子的流场的相互作用在接近。所提出的方法是扩展现有的小尺度转子的空气动力学模型。现有的方法将使用目前正在开发的直升机应用先进的尾流模型进行扩展。此外，非线性的小尺度空气动力学是占使用条的方法。预测方法的开发将受益于在瑞尔森大学大型低速风洞中进行的实验，以及与加拿大公司Aeryon Labs的现有合作，该公司是小型无人机系统的世界领导者。作为拟议研究的一部分，两名MASc，一名博士生和一名博士后将接受应用空气动力学领域的培训。研究结果还将使Aeryon Labs受益，因为它拥有上级设计工具，可以改进其产品线。小型航空系统代表了全球迅速扩大的市场部分，其中加拿大公司，如Aeryon，发挥了重要作用。

The objective of the proposed study is to develop a rotor design and analysis method that is suitable for small multirotor aerial vehicles, such as quadcopters. The subsequent method will result in rotor systems with improved flight performance, such as endurance or high-speed flight characteristics. Although multirotor aerial vehicles are often chosen as remote sensing platforms because of their relative ease to control at hover, control becomes complex during high-speed or maneuvering flight. The challenges of reliable flight controls is due to the nonlinear aerodynamic response typical for small scales and due to the interaction of the flow fields of several rotors in close proximity. The proposed approach is to extend an existing aerodynamic model of small-scale rotors. The existing approach will be extended using an advanced wake model that is currently in development for helicopter applications. In addition, the nonlinear small-scale aerodynamics are accounted for using a strip method. The development of the predictive method will benefit from experiments performed in the large low-speed wind tunnel at Ryerson University and an existing collaboration with Aeryon Labs, a Canadian company that is a world leader in small unmanned aerial systems. As part of the proposed research two MASc, one doctoral student and one postdoctoral fellow will receive training in the area of applied aerodynamics. The results will also benefit Aeryon Labs with superior design tools that will improve their product line. Small aerial systems represent a rapidly expanding market segment worldwide, in which Canadian companies, such as Aeryon, play an important role.
