Abstract

Abstract A hybrid drone called a biplane quadrotor operates in both low (during the horizontal flight) and high (transition maneuver) Angle of Attack (AoA). So, this paper focuses on enhancing aerodynamic force during the transition maneuver. Synthetic Jet actuators (SJAs) can modify airfoil shapes virtually, so either the flow reattaches or flow separation will be delayed. This delay can enhance the aerodynamic force. In this paper, CFD analysis is performed using Ansys Fluent to study the impact of SJA on NACA 0015 airfoil at high (30°) AoA. This study aims to find the best location of SJA for high AoA to get maximum lift enhancement. The outcome of this study reveals that at 85 %, we can get maximum enhancement in the lift.

合成射流致动器在大攻角下的虚拟偏转

摘要一种名为双翼四旋翼的混合无人机在低(水平飞行期间)和高(过渡机动)攻角(AoA)下运行。因此，本文的研究重点是如何提高过渡机动过程中的气动力。合成射流致动器(sja)实际上可以改变翼型的形状，因此要么流动重新附着，要么流动分离将被推迟。这种延迟可以增强空气动力。本文利用Ansys Fluent进行CFD分析，研究了高(30°)AoA时SJA对NACA 0015翼型的影响。本研究旨在寻找高AoA的最佳SJA位置，以获得最大的升力增强。本研究结果表明，在85%时，我们可以获得最大的提升。
