On Transient Temperatures and Thermal Stresses in an Idealised Wing Structure

Abstract

SummaryAn analytical solution is given for the one-dimensional distribution of temperature in a web of an idealised multi-cell wing structure when the adiabatic wall temperature variation is assumed to be either an instantaneous or a linear function of time. The maximum temperature difference between skin and web centre is computed for a range of structural geometries and thermal parameters. Thermal stresses are calculated assuming a parabolic temperature distribution in the web.

Comments on “Transient Temperatures and Thermal Stresses in an Idealised Wing Structure“

“…In ref. 1 an analytical solution was given for the onedimensional distribution of temperature in a web of an idealised, symmetric, multi-cell wing structure when symmetrically heated. It was assumed that the convective heat transfer coefficient, h, was constant, but the adiabatic wall temperature variation was assumed to be either an instantaneous or a linear function of time.…”
