The present invention provides a fast, low-cost, small diverter capable of generating a relatively high impulse (1-5 N-sec) over a short time period. The diverter is adapted for installation in a projectile for steering the projectile in flight by ejecting an end cap or hot burning gases in response to control signals from a guidance system. In one embodiment, multiple diverters are arranged in one or more bands about a flying projectile such as a rocket. Each diverter includes a header assembly providing support for a plurality of electrical leads, a mounting surface either on the header assembly or on a sealing assembly, a reactive semiconductor bridge mounted on the mounting surface and providing an electrical path for the electrical leads at a certain voltage across the bridge, a diverter body supporting the header assembly and containing a prime, wherein the reactive semiconductor bridge and the prime permit a gap, and an end cap or a sealing assembly attached to the diverter body containing the propellant.

Projectile diverter

A semiconductor bridge (SCB) device. In one embodiment, the SCB device includes a laminate layer on top of an insulating material, wherein the laminate layer comprises a series of layers of at least two reactive materials, and wherein the laminate layer comprises two relatively large sections that substantially cover the surface area of the insulating material, and a bridge section joining the two relatively large sections. At least one conductive contact pad is coupled to at least one of the series of layers, wherein a predetermined current through the conductive contact pad causes the bridge section to initiate a reaction in which the laminate layer is involved. In one embodiment, the SCB device includes an integrated diode formed by an interface of the insulating material with another material, such as a metal.
