摘要：The article presents an experimental and numerical approach to estimate ballistic limits of handgun hollow point bullet Action 5 penetrating the target representing a transport airplane fuselage and a forward obstacle. The target containing the composite sidewall,the insulation glass wool layer and the duralumin skin plate is perforated in two combinations – directly and using forward obstacle in form of ballistic gel as substitute biological material to achieve the conditions of firing on-board by Air Marshals,for instance. The ballistic resistance of the fuselage structure fired directly is very poor and in case of firing the gel block first is limited to some extend due to expansion ability of the bullet. The simulation using Finite Element Method system Ansys Autodyn v.14 introduces 2D model presenting the estimation of the ballistic limit in form of gel block thickness for particular combinations of the target based on experiments.
