Abstract: The Dual Tire Shield of the invention mounts between dual tires and helps to prevent debris from getting into the gap between dual tires and/or damaging the tires when it does so. In some embodiments it can also serve as a runflat for dual tires. Debris can become wedged between the sidewalls of dual tires that face each other, or “inner sidewalls” of such tires. The dual tire shield prevents debris from getting stuck between the inner sidewalls of the dual tires and thereby prevents flats caused by sidewall puncture or bead de-seating due to such debris. The device accomplishes this by: Blocking debris from entering the gap between duals and/or prevent debris from being wedged in the gap; keeping such debris from contact with one or both of the tires even if wedged therebetween; and/or ejecting debris from between the tires. Further, the dual tire shield may be made rigid enough and/or include rigid portions so as to act as a runflat in case a tire goes flat regardless of the reason.

Abstract: A method and apparatus for eliminating aircraft landing gear fore-and-aft vibration is provided. The method includes using a tuned mass absorber attached to the landing gear. The gear walk motion has a peak amplitude motion and a pre-peak amplitude motion. The tuned mass absorber includes a mass and a spring, with the mass being oriented to move in a fore-and-aft direction at a frequency and amplitude that counterbalances the gear fore-and-aft vibration.

In one embodiment, the tuned mass absorber is attached to a landing gear strut near the strut's distal end. The motion of the tuned mass absorber mass moves at a frequency and amplitude that counterbalances the gear walk pre-peak amplitude motion. Therefore, the absorber mass is of an amount less than the mass required to counterbalance gear walk peak amplitude motion.
