Gear Load Factor (Reaction Load) Question

Message
[QUOTE="jrmichler, post: 6341181, member: 638574"] Aircraft landing gear design starts with an assumed vertical velocity component. The landing gear absorbs that vertical velocity component by compressing the shock strut. The load on the airframe depends on how fast that vertical velocity is reduced to zero. If the landing gear has long struts with soft springs and low damping, the force is low while the compression distance is long. If the landing gear is rigid, with no compression distance, then the force is very high and things get broken. Your analysis is turning that around by starting with the allowable load factor, and using that to find the required shock strut compression distance. A low load factor requires a long stroke to gradually decelerate the vertical velocity component. A high load factor stops the vertical component faster, so needs less distance. [/QUOTE]
