... commercial aircraft. The crew is also wearing helmets that help attenuate much of the sound. There can be some vibration during re-entry, primarily caused by atmospheric turbulence. It is very minor and not often experienced. There are no harmful forces during re-entry. The most load felt by the crew is approximately two ...

... Pages''' - 9 Abstract The aim of the present work is to introduce a fast procedure to optimize thermal protection systems for re-entry vehicles subjected to high thermal loads. A simplified one-dimensional optimization process, performed in order to find the optimum design variables (lengths, sections etc.), is the first step ...
