摘要

This study is to develop the effective hybrid unmanned aerial vehicle (HUAV) by incorporation of design modifications. The wing and the propeller are two crucial aerodynamic parts of HUAVs that can generate upward forces. Among these two, propellers require a continuous energy, whereas the wing can provide an additional force without power. Henceforth, the imposition of wings and the reduction of the power consumption of propellers are followed everywhere. This work also deals with the performance enhancement and decrease in detection possibilities of HUAV at various phases of its mission profiles. The hybrid multirotor UAV was designed using standard design techniques. The targeted HUAV comprises rectangular wings, forward propellers, and vertical propellers. Rectangular wing plays a major role in this investigation, in which computational fluid dynamics (CFD) was predominantly used in computational approach. Two additional design concepts are proposed and imposed on the base wing to enhance the lift force and reduce the aero-acoustic noises of this HUAV’s rectangular wing. The imposed concepts are wing with winglet and wing with wing fences at the wingtip. The CFD finding indicates that the lift force is enhanced by 17.42% for the winglet case, and the aero-acoustic noise is reduced by 4.64% on average. For the wing fence case, the lift force is enhanced by 18.82%, and the aero-acoustic noise is reduced by 5.1% on average. Based on these results, this work concluded that wing with fence-based HUAVs can perform the mission effectively.
