The very high pressure gas entering the main ballast tanks, rapidly evacuates the ballast water causing the submarine to become quickly buoyant. When the system is activated, the gas generators produce a hot gas that is cooled and directed by ducts to the top of the main ballast tanks. Alternatively, the system can be set to "Manual Mode", allowing the system operator to decide on when to use RESUS. Via the Control and Test Unit, the system can be operated in "Automatic Mode" where the system is automatically started when a predefined diving depth is exceeded. The required number of gas generators to be fired is determined by the Control and Test Unit which determines the diving depth measured by the Diving Depth Measuring Device. The number of gas generators needed for rapid surfacing depends on: Remote Starting Devices are located in a number of positions along the boat enabling RESUS to be activated from more than one location. Once activated, the gas generation cannot be stopped, or reversed. Activation is achieved by the opening of a pyro valve, when liquid fuel gas generators are installed, or an igniter, when solid fuel gas generators are installed. The gas generators are activated to ignite by an electrical signal from the Control and Test Unit. The standard configuration of gas generator is installed in the forward and aft main ballast tanks. From the Cable Distributor, cables are routed via a feed-through between the pressure hull and main ballast tanks to the electrical connections of each of the gas generators. From the Control and Test Unit, an electrical cable harness terminates at a Cable Distributor. RESUS is commanded from a Control and Test Unit located in the submarine control room. Both types of gas generator can be installed in any orientation, even upside down. The solid propellant gas generators produce pressurant gas by combustion. Propellant Tanks for a variety of space propulsion applications. The hydrazine is the same as that used in our hydrazine thrusters and The working principle of the liquid propellant gas generators is based on the catalytic decomposition of hydrazine (N2H4) into a hot gas pressurant. The gas generators may use liquid or solid propellants, depending on the required amount of gas, gas temperature and gas composition. RESUS was developed from the space propulsion industry and exploits the stored chemical energy of propellants to rapidly generate pressurant gas.
