Abstract
A shock strut is provided for a landing gear assembly in an aircraft including a variable load shear collar. The shock strut includes a housing having first and second pistons axially disposed therein. An annular shear collar is rotatably coupled about the housing and includes an inner radial wall, an outer radial wall and a plurality of axially spaced apart shear flanges radially extending from the inner radial wall. The second piston includes a plurality of axially spaced apart force transmitting flanges radially extending therefrom which abuttingly engage the plurality of shear flanges. The degree to which the force transmitting flanges engage the shear flanges corresponds to a circumferential orientation of the shear collar relative to the second piston. The amount of abutting engagement dictates the amount of force required to shear the shear flanges, thereby allowing the second piston to stroke.
