ALE numerical simulation of the crash impact test of an external auxiliary fuel tank

Crashworthy design and energy absorption mechanisms for helicopter structures: A systematic literature review

“…The maximum stress primarily appeared on the top and bottom metal fittings, especially on the top metal fittings of the feeder cells and bottom metal fitting of the after-fuel-cell. Thereafter, they conducted the numerical simulations of a crash impact test of a helicopter external auxiliary fuel tank base on ALE modeling techniques to evaluate the failure behaviors of the fuel tank mounted inside the composite container in the event of a crash [206]. Yang et al [207] conducted the crash impact tests of the nylon woven fabric composite fuel tank, and an FSI finite element model was also established to analyze the dynamic failure behaviors.…”
