Device for absorbing impact applied to moving body

摘要

There is provided a device for absorbing impact applied to a moving body that can exhibit high impact absorption performance in various collision aspects when a moving body collides with an obstacle or the like.;A bladder 10 is provided on the back surface of a front portion of a high-strength frame 2 of an airplane M1. The bladder 10 includes first and second sealing members 11 and 12 that are formed of elastic bag bodies in which a lubricant is sealed. When an obstacle X collides with the bladder 10, the lubricant S generates pressure, which is substantially uniform and perpendicular to boundary surfaces of the first and second sealing members 11 and 12, on the basis of Pascal's principle, and transmits the pressure. Accordingly, when the airplane M1 collides with the obstacle X, high impact absorption performance is exhibited in various collision aspects.
