摘要:

燃气舵作为导弹推力矢量代入控制方案之一,工作时所处的高温燃气环境十分复杂,难以对燃气舵表面力、热载荷开展精确的预示,预测其烧蚀情况。国内外对于燃气舵的气动力特性与相关热环境通过实验及数值计算等方法开展了相关研究,得到了在复杂力、热环境下工作燃气舵的实验数据与数值仿真结果,通过对比两者数据,证明了通过数值方法预测模拟燃气舵烧蚀的可行性与准确性,为后续燃气舵在工程实践中的设计与优化提供了有力的支撑。

Abstract:

As one of the missile thrust vector substitution control schemes, the gas rudder operates in a very complex high-temperature gas environment. It is difficult to accurately predict the surface force and thermal load of the gas rudder and predict its ablation. At home and abroad, relevant researches have been carried out on the aerodynamic characteristics and related thermal environment of gas rudders through experiments and numerical calculations, which proves the feasibility and accuracy of predicting and simulating gas rudder ablation by numerical method, and provides strong support for the subsequent design and optimization of gas rudder in engineering practice.

Key words: gas rudder, thrust vector, numerical calculation, complex environment, ablation
