Semi-Active Isolation of Launch Vehicle Payloads with Very Low Transmissibility

Payloads in a launch vehicle are mounted on standard payload attachment fittings which provide no vibration isolation, imposing severe requirements on payload design. There is a need for inexpensive and effective means to isolate the payload from vehicle vibration. Complications include conflicting requirements for compactness, high static strength, widely varying static load, secure tiedown, low dynamic spring rate and little or no interaction with launch vehicle control dynamics.OmniTek proposes to address this need with a passive/active hybrid (semi-active) system in which the mechanism of isolation is passive and parameters of the mechanical system are automatically adjusted for varying launch conditions. With the inclusion of a novel structural characteristic, the system can meet all the requirements without compromise.The objectives of Phase I are:1. Analyze and characterize the launch environment and equipment to develop design specifications, guides and priorities.2. Develop a number of alternative systems to the conceptual design stage for comparative evaluation.3. Compare and rate the design alternatives against specifications and select one concept for development to the prototype stage.
