Thermoelastic Analysis of an Heterogeneous Orthotropic Nose Cap for a Hypersonic Vehicle

Abstract:

Article Preview

Considering xz plane heterogeneous mechanical properties and thermal-pressure loads, thermoelastic analysis is applied on orthotropic nose cap of a hypersonic vehicle in the flight trajectory. The results show that the thermal-stress of sphere section presents annular, the Mises equivalent stress is of periodicity of 90° in tail so obviously that a reasonable connection is important. Finally, two connections, bolted and plug connection, are considered to relax the overnice tail constrains, and the results show that the plug connection is reasonable for the hypersonic heterogeneous orthotropic nose cap
