Purpose

This study aims to create 6-degree of freedom (SDOF) for computational fluid dynamics (CFD) simulations of body movement, and to validate using the experimental data for empty tank separation from I-22 Iryda jet trainer. The procedure has an ability to be modified or extended, to simulate, for example, a sequential release from the joints.

Design/methodology/approach

A set of CFD simulations are calculated. Both the SDOF procedure and the CFD simulation settings are validated using the wind tunnel data available for the aircraft.

Findings

The simulation using designed procedure gives predictable results, but offers availability to be modified to represent external forces, i.e. from body interaction or control system without necessity to model the control surfaces.

Practical implications

The procedure could be used to model the separation of external stores and design the deployment of anti-radar chaff, flares or ejection seats.

Originality/value

The work presents original work, caused by insufficient abilities of original SDOF procedure in ANSYS code. Additional value is the ability of the procedure to be easily modified.

空油箱与教练机分离的CFD模拟

目的

这项研究旨在为身体运动的计算流体动力学（CFD）模拟创建6自由度（SDOF），并使用从I-22 Iryda喷气教练机进行空油箱分离的实验数据进行验证。该过程具有被修改或扩展的能力，以模拟例如从关节的顺序释放。

设计/方法/方法

计算了一组CFD模拟。SDOF程序和CFD模拟设置均使用飞机可用的风洞数据进行验证。

发现

使用设计的过程进行的模拟可提供可预测的结果，但可提供可修改性以表示外力，即来自车身相互作用或控制系统的外力，而无需对控制表面进行建模。

实际影响

该程序可用于对外部存储的分离进行建模，并设计反雷达糠，火炬或弹射座椅的部署。

创意/价值

这项工作是由ANSYS代码中原始SDOF程序的能力不足引起的，因此是原始工作。附加值是可以轻松修改过程的能力。
