Abstract: A spool-shaped damper piston which is slideably mounted on a damper rod and has an external foam friction element engaging the inner surface of the cylindrical damper body. A pair of axially movable limiting disks are spaced from the spool-shaped damper a predetermined distance to allow movement of the damper rod a predetermined amount before the spool-shaped damper is engaged. In one embodiment, the disks include axially extending tabs which extend through slots in the ends of the spool and selectively engage the foam friction element when the motion of the damping rod exceeds a predetermined threshold. In another embodiment of the invention, the limiting disks include spring fingers extending between the disks and the spool ends to cushion the initial engagement between the disks and the spool as the free space threshold is exceeded.

Abstract: A dry viscous spring strut is provided having at least a top outer housing member, a bottom outer housing member, a shear spring elastomerically associating the top outer housing member to the bottom outer housing member, a selectively pressurizable gas chamber, a subchamber disposed in association with the gas chamber including a plurality of elastomeric particles, a rigid structural member associated with the top outer housing member, and a bearing portion associated with the bottom outer housing member to receive the structural member. The structural member is received in the bearing portion to bear side loading forces to the strut and to limit nonaxial deformation of the strut. Relative movement between the top and the bottom housing members operates to stress the shear spring and the elastomeric particles, vary the pressurization of the gas chamber and subchamber, and vary the positioning of the structural member relative to the bearing portion to absorb shock and dissipate energy imparted to the strut. At least one of the housing members includes a casing wall contiguous to the shear spring configured in an arcuate bell-like form to accommodate deformation of the shear spring during compression of the strut.

Abstract: A tri-adaptive apparatus is disclosed and configured for functioning as a dynamic force isolation and dampening metamaterial that reduces the transmission of dynamic forces between a dynamic force source and an object. In at least one embodiment, the apparatus provides at least one cell unit that provides a pair of opposing first and second cell plates, between which is positioned at least one spring, restrainer and dashpot. An outer surface of the first cell plate is positioned in contact with the dynamic force source. An outer surface of the second cell plate is positioned in contact with the object. The at least one spring, restrainer and dashpot are configured for transferring dynamic force energy mutually between one another while deforming mechanically in response to the dynamic forces transmitted by the dynamic force source.

Abstract: To increase a compactness of damping systems intended to operate in the event of a dynamic landing of an aircraft, a damping system comprises a primary damper device and a secondary damper device. The primary damper device comprises at least one beam, each beam extending along a direction of a longitudinal axis. The damping system is configured so that at rest, the primary damper device has a stiffness greater than a stiffness of the secondary damper device in the direction of the longitudinal axis. When a force is applied to the damping system along the direction of the longitudinal axis, with a value less than a limit value, each beam remains in a compression state. When the force applied has a value greater than or equal to the limit value, each beam undergoes buckling and the secondary damper device undergoes elastic deformation.
