Hybrid Modeling Method of SDR Interstage Valve Based on Mechanism and Data‐Driven
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 Variable‐throat adjustment is the most practical flow regulation method of solid ducted rocket ramjet (SDR). The high‐fidelity mathematical model of the interstage valve is the basis for realizing high‐precision gas flow and thrust regulation. In this paper, the complex effect of gas was divided into load and throat deformation effect.
