  • Flexure elastomer antenna isolation system
    Patent number: 7248228
    Abstract: A vibration isolation system (100) for a payload (102). The vibration isolation system provides a level of vibration isolation for all vibration translational and rotational components, while minimizing the moment of the payload mass relative to the isolation system. The system includes a base (104) and a plurality of vibration isolators (114). Each vibration isolator includes a semi-rigid first support member (202) having first portion (204) positioned below the base and an opposing second portion (206) positioned above the base, and a second support member (208) having a first portion (210) fixed to the base and an opposing second portion (212) extending above the base. An elastomeric coupling (228) couples the first support member to the second support member at a height that is approximately equal to a height of a center of gravity (302) of a combined mass of the base and the payload above the base.
    Type: Grant
