Digital Micro-Thruster Chip

THE DIGITAL PROPULSION "ROCKET CHIP" consists of several layers of silicon and glass packaged in a standard 20-pin ceramic dual-inline electronics package. This prototype contains 15 individual thrusters, in the central 3 by 5 array. The visible bond wires are connected to resistors in each thruster that initiate combustion of the lead styphnate fuel.
