    摘要: A gridded ion propulsion system comprising two power controllers, four ion thrusters, and two switch assemblies. One switch assembly is connected to the two power controllers and to two of the four ion thrusters. The other switch assembly is connected to the two power controllers and to the other two ion thrusters. Each switch assembly has first and second switching states which can be selected to enable either power controller to supply power to any one of the four ion thrusters. Each switch assembly comprises a respective movable body and a respective multiplicity of switches which change state in unison when the movable body changes position. For example, the movable body may be a rotatable hollow shaft driven by a stepper motor.

    摘要: A relay telemetry system enables an ion propulsion system to self-test the critical relay configuration prior to supplying high-voltage power to any thruster. This test detects whether any critical relay has failed to switch properly or is in the wrong configuration. In the test mode, an onboard computer initiates the application of a low-voltage test voltage (nominally 15 V) to the high-voltage circuits (when the high voltage is off) by a stimulus circuit. Sensing circuits detect the inputs and outputs of the system connections in response to this stimulus. If the test voltage appears on an input or output where it is not expected, then a relay fault has occurred and will be detectable in telemetry sent back to the onboard computer.
