Development of Fluidic Guidance for KEW (Kinetic Energy Weapon) Projectiles
Abstract
In order for KEW projectiles to reliably destroy hostile ICBMs they must use some form of guidance. To be practical, KEWs must be lightweight, able to withstand high g forces, and insensitive to nuclear and electro-magnetic effects. Laser command guidance can guide a KEW to a target 'basket' area whereupon a strapped-down seeker can guide for a hit-to-kill. Key elements of such a KEW system are a laser detector/processor and lightweight control thrusters. Phase I demonstrated miniature photo-acousto-fluidic elements that detected, processed and demodulated FM laser signals riding on a 1.0 watt/sq. cm carrier. Using laminar digital fluidic logic, the ability to command ON or OFF any one of four thrusters was also demonstrated. In addition, high efficiency (>93%), 10-lb net force, single- and dual-axis fluidic diverter/thrusters, were designed and could result in a 300 - 500 gm fully guided KEW projectile. Recommendations are made for Phase II efforts to build, test and demonstrate the diverters and to integrate a light weight detector. Brassboard cold and warm gas operation should also be demonstrated. The laser detection/processing circuitry needs to be designed to operate with propellant gasses.
