Bipropellant/Dual-Mode Systems Bipropellant Systems - 30-
Bipropellant Systems (Operate) - 31- Bipropellant systems are characterized by the combustion of two (Bi) propellants, a fuel (e.g. MMH) and an oxidizer (e.g. N2O4) to produce thrust. The propellants are injected separately into the bipropellant thruster combustion chamber where they react spontaneously (hypergolic propellant) to perform high-temperature, low molecular weight combustion products, which are the expelled through a nozzle. The system basically consists of a pressurizing-gas system, propellant tanks (with surface tension propellant management devices), propellant lines and thrusters. Unlike hydrazine thrusters, bipropellant thrusters accept only a limited range of propellant inlet pressure variation of ≤ 2. Therefore, the high-pressure gas, generally nitrogen or helium is regulated to the desired tank pressure, e.g. 17 bar. This mode of operation is also referred to as the pressure constant mode. The system contains check valves upstream of the propellant tanks to prevent possible back-flow, mixing, and combustion of the propellant vapors in the common pressuring gas line. Relieve valves are incorporated in the system upstream of the propellant tanks to prevent system rupture in the event of a pressure regulator failure. Filters are provided in the propellant lines directly upstream of the thruster valves to prevent clogging of the injector or damage of the valve seat by entrained foreign material. Finally, the system contains pyro- or latch valves, line pressure transducers, fill and drain valves and various test ports for system check out.
