Shock strut assemblies for landing gear

A landing gear, comprising:

• an axle configured to support a tire;
• and
• a shock strut assembly coupled to the axle, the shock strut assembly including:
• a strut cylinder;
• a strut piston configured to telescope relative to the strut cylinder;
• and
• a lock tab configured to translate with the strut cylinder, wherein the lock tab is biased toward an inner diameter surface of the strut cylinder, and wherein a groove formed in the inner diameter surface of the strut cylinder is configured to receive the lock tab, wherein a length of the groove is configured such that the lock tab is located in the groove when the shock strut assembly is in a compressed position and outside the groove when the shock strut assembly is in a fully extended position.

A shock strut assembly for a landing gear, comprising:

• a strut cylinder;
• a strut piston configured to telescope relative to the strut cylinder;
• and
• a locking system comprising a lock tab configured to translate with the strut cylinder, wherein the lock tab is biased toward an inner diameter surface of the strut cylinder, and wherein a groove formed in an inner diameter surface of the strut cylinder is configured to receive the lock tab;
• the locking system configured to restrict rotation of the strut piston relative to the strut cylinder in response to compression of the shock strut assembly, wherein the locking system is configured to be in an unlocked state when a stroke length of the shock strut assembly is greater than a threshold stroke length, and
• wherein the locking system is configured to be in a locked state when the stroke length of the shock strut assembly is less than or equal to the threshold stroke length.
