Load sensor for helicopter skid energy-absorbing landing gear

摘要

The shear beam extends between installation tabs (32, 34) in which are defined holes for mounting the load sensor to the helicopter fuselage (18) by fasteners (64). An arcuate part of the beam is a load bearing area which senses the change in shear force exerted by the fuselage cross-tubes (16) under landing load. On either side of the shear beam, a pair of webs of reduced cross-thickness mounts a set of four steam gauges (5a,b,c,d) each with its grid lines disposed at forty five degrees of arc relative to the beam. A raised boss (60) sustains overloads as during a crash or heavy landing.
