Abstract

The main objective of this paper is to evaluate the aerodynamic performance of a modified blended wing-bodied re-entry vehicle by computational fluid dynamics. This analysis examines the airflow properties like pressure, density, and temperature under hypersonic flow. The study of a blended wing model at different Mach speeds and angles of attack is also included in the research paper. All the simulations in this paper are performed using the computational fluid dynamics tool of ANSYS CFX. Shear stress transport (SST) turbulence computational fluid dynamics model has been used for numerical analysis. Various inlet conditions are applied to get the aerodynamic parameters. The results revealed that the best Re-entry condition is from 10 to 20 degrees angle of attack at Mach 22, and the vehicle is very stable at a high angle of attack and Mach number. The obtained results have been validated with the public domain literature. The blended wing body has been thoroughly examined in various important locations, particularly the spacecraft nose and flap sections.

利用 ANSYS CFX 提高混合翼身再入飞行器的气动性能

本文的主要目的是通过计算流体动力学评估改进型混合翼身再入飞行器的气动性能。该分析研究了高超音速流动下的气流特性，如压力、密度和温度。研究论文还包括在不同马赫数速度和攻角下对混合翼模型的研究。本文中的所有模拟均使用 ANSYS CFX 计算流体动力学工具进行。剪应力传输（SST）湍流计算流体动力学模型被用于数值分析。应用各种入口条件来获得气动参数。结果表明，最佳的再入条件是在 22 马赫时的 10 至 20 度攻角，飞行器在高攻角和高马赫数下非常稳定。所获得的结果与公共领域的文献进行了验证。对混合翼体的各个重要位置，特别是航天器机头和襟翼部分进行了彻底检查。
