Combustion instability modeling of Solid Rocket Motors (SRM) remains a topic of active research. Many rockets display violent fluctuations in pressure, velocity, and temperature originating from the complex interactions between the combustion process, acoustics, and steady-state gas dynamics. Recent ...

COMBUSTION gasesHYPERSONIC aerodynamicsScramjet based on solid propellant has become a potential choice for the development of future hypersonic vehicles. In this paper, a boron-containing solid rocket scramjet based on the central strut injection was proposed, and the ground direc...
factors and trends, related to the usage of two or more sets of inert particles comprised of the same material (nominally aluminum) but at different diameters for the suppression of axial shock wave development, are numerically predicted for a composite-propellant cylindrical-grain solid rocket ...
Sub-models will consider only a restricted number of physical processes that drive particle combustion and movement. The rocket core flow is assumed as a cylinder with mass injection from sides (Fig. 1). The geometry is fixed and the radius does not change during the simulation time of one ...
第37卷第3期 固体火箭技术JournalofSolidRocketTechnology Vol.37No.32014固体燃料凹腔结构对超声速流动的影响①陶欢,魏志军,迟鸿伟,孙巍伟,王宁飞(北京理工大学宇航学院,北京 100081) 摘要:针对在超声速来流下燃烧室中增加凹腔结构能否提高固体燃料的掺混效果进行研究。采用基于密度的二阶迎风差分数值方法模拟了固体...
Aluminum-based propellants are commonly used in solid rocket motors (SRM) due to their high energy densities. However, the alumina (Al2O3) particles produced during aluminum propellant combustion present performance issues. These particles flow along the combustion chamber to the nozzle in liquid for...
Solid Rocket Motors frequently experience unsteady gas motions and combustion instabilities. Pressure oscillations are a well-known problem of large solid rocket motors (e.g. those of the US Space Shuttle, Arianne 5 P230 and P80). Pressure oscillations l
