Abstract

The scaled solid rocket engine plays a crucial role and holds significant meaning.Firstly,it allows for cost-effective experimental investigations.By reducing the size,the cost of materials,manufacturing,and testing is much lower compared to full-scale engines.This enables researchers to conduct a large number of tests to study various parameters such as combustion efficiency,thrust characteristics,and material performance under different conditions.Secondly,it helps in understanding the fundamental physical processes involved in the operation of a solid rocket engine.The scaled model can provide valuable insights into the flow patterns,heat transfer,and chemical reactions within the engine,which are essential for optimizing the design and performance of the full-scale version.In this paper,based on the second similarity theory,a new approach on the solid scalded rocket design through dimensional analysis has been proposed.The structural response behaviors of the full-scale motor and the scaled motor under the ignition pressurization load have been demonstrated.At the same time,the pressures along with the burning time during the whole working period have both been calculated by employing the zero-dimensional interior ballistic governing equations.The results bear out that both the structural response and interior ballistic performances are highly similar to each other,which proves that the design method propose in this paper is reasonable and credible.

Key words： Solid motor rocket; Similarity theory; Scaled principle; Grain structural integrity
