Rocket propulsion unit is very essential to for launching a space mission. Rocket propulsion has various types. In that hybrid rocket propulsion is an emerging and innovative technology with strong features such as economical, safe, and simple propulsion devices. On the other hand, few issues such as mixing ratio changes, low regression rates and inefficient mixing, restricts their application as a the major area. This research represents an improvement of an important issue, namely the low fuel regression rate. If an oxidizer velocity increases at the surface of fuel, the regression rate of fuel may increase due to the oxidizer flow above the burning surface produces shear stress, which erodes the fuel surface and causing the missing of fuel and air. Methods to increase the shear stress are to induce an oxidizer vortex inside the combustion chamber. In the current analysis, a diaphragm has been used to create the air vortex inside the solid fuel grain. A sequence of static rocket firing was accompanied for different position diaphragm. Operating condition has been kept constant for all the run. The results of six laboratory scale hybrid rocket test firing using polyvinyl chloride and gaseous oxygen are presented here. It has been found that the regression rate of solid fuel grain has been improved for the diaphragm cases.
