Abstract

The effect of heat conduction of material on the temperature distribution in the vicinity of a wing leading edge in hypersonic flight is investigated. The theory is based on a conducting plate subjected to aerodynamic heating. It is found that the role played by the conductivity of the materiel and the leading edge thickness in moderating the nose temperature is very significant. Detailed discussions of the numerical solutions for various shapes of leading edge era given. An experimental technique has been developed by which a number of models representing a wing leading edge oan be tested and the results thus obtained are compared with those predicted by the theory. * Replgces A.R.C.31 445-2
