运载火箭空中发射系统约束建模与仿真

Constraints modeling and simulation of the internally carried air-launched vehicle

约束模型的建立与分析是研究运载火箭空中发射系统的一个重要组成部分。缆索系统在内装式和拖曳式等重要的运载火箭空中发射方式中对系统起约束作用,通过对两种有代表性的缆索模型建立数学模型,进而导出了内装式运载火箭空中发射系统的约束模型。运用所建立模型在Matlab环境下编制了内装式空中发射系统约束仿真程序,并进行了仿真运算与仿真结果分析。研究结果可为相应空中发射系统的设计、性能预测和评估提供依据。

The establishment and analysis of the restriction model are an important component of air launched vehicle system. Cable system plays a restrict role in the internally carried air-launched and drag-style air-launched vehicle system. Dynamic equations of two kinds of typical cable model have been established, thus derived out the constraint model of the internally carried air-launched vehicle system. Applying the model the internally carried air- launched vehicle system constraints simulation program have been established in the Matlab environment, the simu- lation program has been run, and simulation results have been analyzed. The results can provide assistance for the corresponding air-launched vehicle system＇ s design, performance prediction and assessment.
