STUDY OF LIQUID METAL NAK-77 FOR APPLICATION IN FLIGHT CONTROL SYSTEMS

Abstract

A survey of potential aerospace applications and system performance requirements was made. A ten-stage centrifugal pump rated at 3000 psi, 16 gpm, and 1200 F was successfully tested at pressures above 2200 psi, temperatures exceeding 1000 F, and speed above 31,000 rpm. Flow exceeded the rated capacity of the unit. A 1200 F, two-stage servovalve was designed and built. Static tests with oil and NaK-77 were conducted. A linear actuator rated at 15,000 pounds output at 1200 F was re-built and tested with NaK-77 for part of an experimental servoactuating subsystem. A nuclear testing facility was located and a design layout of an experimental, air/nuclear servoactuating subsystem was completed. Design criteria and design layouts for a flight test system suitable for installation in the elevon section of the XB-70 was also completed. (Author)
