Propellant Tank
A propellant tank is a specialized container designed to store and manage propellants, typically fuel and oxidizer, used in aerospace systems such as rockets, satellites, and spacecraft. These tanks are engineered to withstand extreme conditions, including high pressures, wide temperature ranges, and corrosive chemical environments.
Constructed from lightweight yet durable materials such as aluminum alloys, stainless steel, or composites like carbon fiber, propellant tanks are designed to minimize mass while maximizing structural integrity. They may be spherical, cylindrical, or toroidal in shape, depending on space constraints and performance requirements.
Inside, the tank may include features like bladders, diaphragms, or surface tension devices to ensure proper fuel delivery in microgravity or low-pressure conditions. External features often include valves, sensors, and insulation, as well as interfaces for integration with propulsion systems.
In summary, a propellant tank is a critical component of any propulsion system, serving as the safe, efficient reservoir for the propellants that generate thrust.
