Abstract
  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

Abstract
  Helicopters can be a source of loud noise. The high production noise of helicopters makes them unsuitable for densely populated areas, especially in low-flying conditions. This study examines methods and offers solutions to reduce or eliminate the noise produced by helicopters. Several methods have been ...  Read More
