  Abstract: In this article, to investigate the severity of damage to the helicopter pilot under the crash impact, the numerical simulation of the real helicopter cockpit seat has been done. To limit the complexity of the problem, a fully vertical impact was considered as a reference scenario for the assembly ...  Read More
