Biodynamic Response to Windblast.
ADVISORY GROUP FOR AEROSPACE RESEARCH AND DEVELOPMENT NEUILLY-SUR-SEINE (FRANCE)
Pagination or Media Count:
The volume contains the text, discussion and technical evaluation of papers presented at the AGARD Aerospace Medical Panel Specialists Meeting which was held at Toronto, Canada, 6 May 1975. The specific problem of windblast was considered as it affects human tolerance to high-speed ejection. Injury mechanisms were discussed in several papers and it was shown that most injuries are caused by excessive motion of the limbs, rather than by the direct effect of wind pressure. Ejection injury mechanisms were also considered in relation to windblast from conventional and nuclear explosions. Protection was considered along two lines. The prevention of limb motion by means of restraints was shown to be as practical for the arms as for the legs, and could be extended to provide the arm retraction needed in safe command ejection. It was also shown that the provision of a stable ejection seat would greatly ameliorate the windblast problem. The problems of head restraint and helmet loss were also considered.
