SHOCK ABSORBER FOR NAVIGATION SYSTEM VIBRATION PROTECTION Russian patent published in 2025 - IPC G01C23/00 F16F15/126 

FIELD: vibration protection systems.

SUBSTANCE: invention relates to means of protection against vibration and impact loads acting on inertial navigation systems (INS) of an aircraft. Essence of the claimed device consists in the fact that the annular holder on the resilient element having external recesses is arranged symmetrically relative to its edges, wherein the surface of the rear end cylindrical portion of the bushing relative to the longitudinal axis is 0.33 of the surface of the front end cylindrical portion of the bushing; the surface of the larger base of the conical section of bushing is 0.74 of the outer surface of the resilient element relative to the transverse axis; maximum expansion of the resilient element is 0.78 of the surface of the bushing relative to the longitudinal axis; annular groove for the mating surface of the annular holder is a body of rotation consisting of symmetric damping elements forming a Y-shaped mounting slot for the annular holder, note here that thickness of damping elements makes 0.61 times of minimum width of Y-shaped slot.

EFFECT: obtaining an equal-stiffness damper in axial and radial directions and, as a result, providing equivalent effect of external factors on the unit of sensitive elements of the INS.
