专利汇可以提供Energy absorbing landing gear专利检索,专利查询,专利分析的服务。并且A landing gear for helicopters in which a member having a static spring rate and plastic yielding characteristics is mounted in series with a member having a static spring rate and a velocitysensitive restraining force. The combination serves to provide for appropriately ''''soft'''' landings under conditions of light gross weight and/or low vertical descent speed, and is also capable of absorbing the forces generated during ''''hard'''' or crash landings under conditions of heavy gross weight and/or high vertical descent speed. By designing the yield point of the plastic yielding member to a force approximately equal to the resistance offered by the velocity-sensitive unit at the time that is ''''bottoms out,'''' the efficient energy absorbing properties of the plastically yielding member are employed to extend the energy absorbing capabilities of the gear.,下面是Energy absorbing landing gear专利的具体信息内容。
