Abstract:

Alameda Applied Sciences Corporation proposes to develop a new Clustered Vacuum Arc Thruster (CVAT) as an electric propulsion micro-thruster for microspacecraft with mass kg of total propellant. If the feed mechanism involves moving parts, its reliability is an issue, especially with active control. An innovative solution to this problem is proposed: deploy an array of individual, static thrusters, each of which delivers 10g of total eroded propellant. An array of 100 such devices would then deliver a kg of propellant, with no moving parts. The innovation is the use of miniature solid-state switches in our inductive PPU driver that enable programmable switching of the drive power pulses from one thruster to another. By so doing, one effectively switches power out of a given cathode once it has completed its useful mission life. Such a Clustered Vacuum Arc Thruster array (CVAT) has no moving parts and yet delivers 1kg propellant loads for various nanosatellite missions.
