Overview
The 5N thruster is a monopropellant hydrazine thruster suitable for maneuvering the satellite and is qualified for the Israeli MOD programs. The thruster consists of a Flow Control Valve (FCV) that is operated by solenoid and a Thrust Chamber Assembly (TCA). The TCA has a bell-shaped nozzle with an expansion ratio of 50 welded to the decomposition chamber. Perforated Hayness-alloy tubular element acts as a thermal barrier between the FCV and TCA. The FCV has an inlet port, springs, valve body; coils, plungers, seats and a mounting flange. For repeatable and long duration operation, the required initial thermal condition was provided by electric catalyst bed heater (CBH) with two resistance coils. MS 33656-4 threaded connector is used for the connection of the thruster inlet to the system tubing which complies with the screwed connection requirement. The thruster has a flight heritage and is free of any ITAR restrictions.
