PRESSURIZATION SYSTEM FOR PROVIDING PROPELLANT, PRESSURE CONTROL METHOD THEREOF AND COMPUTER READABLE RECORDING MEDIUM STORING PROGRAM PERFORMING SAME

摘要

The present invention relates to a pressurization system for providing a propellant, a pressure control method thereof and a computer readable recording medium storing a program performing the same. According to an embodiment of the present invention, the pressurization system for providing a propellant, which provides a propellant to a thrust generation device including: a propellant tank; and a projectile engine provided with a propellant from the propellant tank to generate thrust, comprises: a high pressure gas tank storing a pressurizing gas; a flow rate control valve having at least two types of valves having each different driving speed and each different flow coefficient and controlling the flow rate of the pressurizing gas supplied from the high-pressure gas tank to the propellant tank by controlling the opening and closing of each valve; a pressure sensor positioned on the propellant tank to measure pressure of the propellant; a pressure relief valve positioned on the propellant tank to relieve pressure by exhausting and recovering the pressurizing gas; and a programmable logic controller (PLC) controlling the flow rate control valve and the pressure relief valve to allow the pressure of the propellant, which is measured by the pressure sensor, to be within a set target pressure range.;COPYRIGHT KIPO 2017
