ABSTRACT:
In a shock strut for an aircraft landing gear having inner and outer elongated telescoping tubes and a primary orifice selected and designed to attenuate the load level to a certain design condition which is compatible with the aircraft's structural threshold up to a certain overload sink speed, a load attenuating valve which opens when the design velocity is exceeded. The load attenuating valve includes secondary orifices held closed by a tension fuse which ruptures and opens the orifices in parallel to the primary orifice for additional flow, thus keeping the pressure drop across the orifices to an acceptable level so as to permit full stroking of the strut. In this way, as much energy as possible is absorbed before the load is transmitted to the aircraft on failure.
