PRESSURIZING DIFFUSER AND LIQUID PROPELLANT ROCKET USING THEREOF

摘要

A diffuser for pressurizing and a liquid propellant rocket using the same are provided to prevent the drop of the pressurized gas by passing through the diffuser and spray the pressurized gas uniformly in the whole area of the outlet of the diffuser. An inflow pipe is arranged in one side of a storage tank and the pressurized gas is inputted to the inflow pipe. A diffuser body is equipped in the bottom of the inflow pipe and sprays the pressurized gas into the inside of the storage tank. A conical pitching plate(110) is equipped inside the diffuser and includes a plurality of flow holes in a plate with a conical shape. The conical pitching plate is separated from the diffuser body with a predetermined interval and is installed adjacently to the inflow pipe. A support stand(120) is arranged in the bottom of the conical pitching plate and is installed in the diffuser body. The support stand supports the conical pitching plate.
