' 'K' ' FACTOR DETERMINATION OF FOUR TYPES OF PANEL CONSTRUCTION IN F-111 AIRPLANE,

Abstract

Thermal conductivity measurements were made on panels designed to insulate certain areas of the F-111 airplane fuel tank. Four general types of panels were tested: Type I. All fiberglass panels exhibited the lowest ''K'' factors of all panels at mean temperatures below 300 F. Type II. An aluminum skin-fiberglass core panel exhibited a steep slope when ''K'' was plotted against temperature. Type IV. Microglass balloon filled panel tests revealed that higher glass concentrations of the coating result in lower ''K'' factors. (Author)
