// PROPULSION SYSTEMS AND ENGINE TECHNOLOGY TERM
Pressurization System
A pressurization system in aerospace uses a stored gas to maintain constant pressure inside propellant tanks, ensuring fuel and oxidizer flow reliably to rocket engines or thrusters during flight. This is crucial for consistent engine performance and to prevent tank damage in various flight environments.
TECHNICAL DEFINITION
An aerospace pressurization system is a critical fluid management subsystem utilizing inert gas, such as helium or nitrogen, from high-pressure storage tanks, regulated via valves and lines, to maintain positive pressure within propellant tanks; this ensures reliable, cavitation-free propellant feed to rocket engines or thrusters by overcoming hydrostatic and acceleration forces, crucial for consistent thrust and structural integrity during mission phases.
