Scaling of Hybrid Rocket Motors with Swirling Oxidizer Injection

The present research focuses on the use of a swirling oxidizer injection, in a hybrid motor with a classical cylindrical solid fuel grain with a circular port, i.e. a side burning grain. The conducted study is mainly a numerical analysis, that pays a particular attention on the scaling behaviour of this particular configuration of hybrid rocket motor, in relation to the variation of the geometric swirl number and of the oxidizer mass flux
