  • Modular MEMS thruster system utilizing rolled storage, selective deployment and independent initiator
    Patent number: 8534042
    Abstract: A new micro electro-mechanical system (MEMS) satellite thruster is described. An example of the new MEMS thruster includes a propellant layer on a flexible substrate to make a rolled propellant that can be mounted on a reel-to-reel system. Sections of the rolled propellant are rolled over a separate activation blast plate to initiate the propellant on that section, providing thrust. The new MEMS thruster can also be made with segmented propellant sections. The new MEMS thruster can be made in a variety of configurations and as a modular system that can be attached to existing satellites.
