A PROGRAM TO DETERMINE HIGH BLAST-INDUCED AIR LOADS AND STRUCTURALnRESPONSE OF LIFTING SURFACES

摘要

High blast induced airloads and the structural response of lifting surfaces are investigated for determining aircraft vulnerability and safety. Of major interest is the case where the primary structure of the lifting surface undergoes deformations of an inelastic nature. Structural response prediction methods, for completely elastic response conditions, are well documented and quite reliable. However, the methods of evaluating the structural response must he extended into the inelastic region and verified through the use of experimentally collected data.
