A regression rate which is a important design parameter in Hybrid rocket propulsion has a different characteristic with various solid fuels. And each solid fuel's regression rate varies with oxidizer mass flows. In this study, PE & PMMA are used as fuel. The relation(r = αX^(n)) between oxidizer mass flux(G_(O), G_(O AVG), G_(total)) and regression rate is found experimentally
As a result, PMMA's pyrolysis amount is bigger than PE's, when same oxidizer mass flow is supplied. because the regression rate of PMMA is higher than PE's. It is also shown that regression rate of PMMA has more effect on oxidizer mass flow than PE.
