Thruster controller for depth control thruster used in spacecrafts operated with gaseous cryogenic fuels, has control device with control channels for gaseous fuel and oxidizer gas, respectively, and device to correct control of mass flow
Thruster controller for depth control thruster used in spacecrafts operated with gaseous cryogenic fuels, has control device with control channels for gaseous fuel and oxidizer gas, respectively, and device to correct control of mass flow
The controller has a control device with a control channel (1) for gaseous fuel i.e. liquid hydrogen, and another control channel (2) for oxidizer gas i.e. liquid oxygen, where the control channels are connected with a control unit (16). A device corrects control of mass flow to a combustion chamber of a depth control thruster (3). The control unit comprises a snapped process computer (17). The control unit is equipped with electronic tables (19-21) and snapped computing algorithms. The control unit controls total mass current and ratio of mass flows along the channels over an output (22).
