New Techniques for Fabrication of Airborne Electronic Equipment

New techniques, materials, and methods for the fabrication of airborne electronic equipment as applied to a particular equipment, which have been developed at the National Bureau of Standards, are described. Emphasis has been placed in attaining reliable equipment performance, and steps taken to achieve reliability are discussed. A miniature radar set has been developed using these new techniques and materials. The equipment is capable of operating in an ambient temperature as low as -65 degrees C., and much higher than +55 degrees C. Internal temperatures are minimized by an internal cooling system which is provided to cool the equipment under the high ambient temperature conditions. The equipment is pressurized, and is not limited by altitude. It consists of a single major unit plus accessories. The weight of the entire system is fifty-five pounds.
