Abstract

This project aims to design a hybrid drone with fixed wing for the stable cruising as well as multi-copters for the vertical take-off and landing (VTOL) operations. Drones are utilized for number of applications leading from transportation to the surveillance purposes. Some drones are popular for their stable operation, while other for optimum landing and takeoff. Therefore, numerical analysis was performed on propeller, landing gear as well as on whole structure of the drone. The observed result from CFD analysis show that the velocity distribution had maximum velocity of 40 m/s at the mid span of the drone. In addition, the maximum stress obtained was on the landing gear with approximate value of 185 MPa which is due to the weigh and payload of the drone. The final model was built after the analytical and numerical analysis in order to achieve sustainable and reliable prototype.

固定翼与多旋翼组合的气动研究与设计

该项目旨在设计一种用于稳定巡航的固定翼混合无人机，以及用于垂直起降(VTOL)操作的多架直升机。无人机被用于从运输到监视目的的许多应用。一些无人机因其稳定的运行而受欢迎，而另一些则因其最佳的着陆和起飞而受欢迎。因此，对无人机的螺旋桨、起落架以及整体结构进行了数值分析。计算流体动力学(CFD)分析结果表明，无人机跨中处的速度分布最大速度为40 m/s。此外，由于无人机的重量和有效载荷，在起落架上获得的最大应力约为185 MPa。通过分析和数值分析，建立了最终的模型，以实现原型的可持续性和可靠性。

期刊介绍： World Earthquake Engineering was founded in 1985 and is now a quarterly journal. It is an academic journal in the field of earthquake engineering under the supervision of China Earthquake Administration (CEA), and co-sponsored by the Institute of Engineering Mechanics of China Earthquake Administration (IEMCA) and the Chinese Society of Mechanics (CSM). The journal aims to introduce the latest research results in the field of earthquake engineering at home and abroad, to promote international academic exchanges in the field of earthquake engineering, and to serve China's seismic prevention and anti-seismic work. China Association for Science and Technology (CAST) selected China's high-quality scientific and technological journals in different fields for its hierarchical catalogue, and the journal was selected as T2 level (internationally renowned journals) of earth science and geophysical journals. Outstanding journal for the implementation of the CAJ-CD Code in the implementation of the Chinese Academic Journals (CD-ROM Version) Retrieval and Evaluation Data Specification (CAJ-CD Code) in the evaluation of excellence activities; included in the cultivation bank of Heilongjiang Province's high-quality journal projects.
