Abstract
SOME structural design problems produced by aerodynamic heating are examined to determine design approaches that may help alleviate undesirable effects. Loss of strength and creep of structures at uniform elevated temperatures are discussed, and the probable effect of creep on design of airplane structures is indicated.
Nonuniform temperature distributions produced by changing flight conditions are discussed to introduce the subject of thermal stresses and their possible effects on the structure, thermal buckling, and severe loss of stiffness at stress levels well below those producing buckling. Design approaches that can be used to prevent thermal stresses and consequent adverse effects are then indicated.
