气动热研究在火箭橇试验中具有至关重要的作用,它不仅能够为火箭橇的结构设计提供关键依据,还能确保其在高速运行中的安全性和可靠性。文章重点研究了空间离散格式、湍流模型、法向第一层网格高度等因素对气动热计算结果的影响,并以典型高速火箭橇简化模型为研究对象,开展了详细的气动热计算,通过分析橇体关键特征位置热流分布规律,揭示了轨道反射激波和整流帽对舱体侧面的干扰机制。此外,基于某单轨火箭橇试验数据,对仿真与实验结果的一致性进行了定量分析。研究结果表明:(1)火箭橇气动热预示中,空间离散格式宜选用Roe格式,湍流模型宜采用S-A模型,且法向第一层网格高度应不大于1×10-7m;(2)典型橇体中无干扰区域的热流峰值为24050kW/m2,主要集中在连接段;轨道反射激波在锥段舱体下半部分形成干扰,整流帽对舱体侧面形成明显的干扰,均使得干扰区域热流显著增大;(3)温度仿真结果与试验结果的最大偏差为17.88%,表明该数值方法可用于后续火箭橇气动热预测。本文的研究成果为火箭橇试验的工程应用提供了重要的理论支持。

Aerodynamic heat research plays a crucial role in rocket sled testing,providing essential support for structural design and ensuring safety and reliability during high-speed operation.This paper focuses on the impact of spatial discretization schemes,turbulence models,and the height of the first normal grid layer on aerodynamic heat calculation results.Using a simplified model of typical a high-speed rocket sled,detailed aerodynamic heat calculations were conducted.The study analyzed the heat flux distribution at key locations on the sled body,revealing the interference mechanisms caused by track-reflected shock waves and fairings on the side of the vehicle.In addition,this paper conducts a quantitative analysis of the consistency between simulation and experimental results based on data from a single-track rocket sled test.The results indicate that:(1) For aerodynamic heat prediction in rocket sled,the Roe scheme is recommended for spatial discretization,the S-A model is preferred for turbulence modeling,and the height of the first normal grid layer should not exceed 1×10-7m; (2) In the typical sled body,the peak heat flux in interference-free areas reaches 24050kW/m2,primarily concentrated in the connecting section.Interference are formed on the lower half of the conical section due to track-reflected shock waves,and significant interference is observed on the vehicle’s side due to the fairing,both of which lead to a substantial increase in local heat flux; (3) The maximum deviation between the simulated and experimental temperature results is 17.88%,demonstrating that the numerical method can be used for subsequent aerodynamic heat prediction of rocket sleds.The findings of this study provide important theoretical support for the engineering application of rocket sled testing.
