Abstract
Major technological advancement and practical applications evolved during the B-70 program. Typical of these are the application of the compression lift and folding wing tip concepts; utilization of stainless steel honeycomb, titanium, and high-strength tool steel in airframe structure; development of hydraulic systems components, such as pumps, actuators, and fittings with metallic seals to operate at 4000 psi and 450 F; and development of high-temperature, high-altitude a-c electrical components, such as true a-c coil relays and an all-electric throttle system. Experience accumulated during XB-70 development and testing confirms their applicability to other current and future aerospace systems, such as the SST and the C-5A.
