STRUCTURAL HEATING EXPERIENCES ON THE X-15 AIRPLANE

Abstract

Identifiers: X-15.A survey of maximum structural temperatures measured on the X-15 airplane during speed flights up to a Mach number of 6 is presented. Structural problems caused by local hot spots and discontinuities encountered during the flight are also discussed. In general, the hot-structure concept used for the primary structure of the X-15 airplane has proven to be satisfactory. Problems have arisen only from local hot spots and discontinuities. These problems include windshieldglass failures, airflow through openings in the external structure, and structural discontinuities. Comparison of calculated and measured internal temperatures has shown that satisfactory thermal gradients through the structure can be calculated from known heat input to the exposed surfaces.
