Digital Micro-Thruster Chip


THE DIGITAL PROPULSION "ROCKET CHIP" consists of a three-layer sandwich of silicon and glass. packaged in a standard 24-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.
