SIMPLIFIED SYSTEM FOR ULTRASONIC BONE ASSESSMENT

Not Available Under the current SBIR solicitation, the Air Force is interested in the development of an improved material for o-rings and seals for use in pressurized Halonr 1202 applications. Specifically, the Air Force is interested in developing these materials to support applications in fire suppression systems used in Air Force weapon systems. Halonr 1202, or bromodifluoroethane, is stored under pressure for use as a fire suppressant in these systems. The packing materials currently used to support this application have been found to deteriorate at an unacceptable rate, causing the seals to fail under pressure and allowing the Halonr gas to escape to the atmosphere. Longer service life materials are needed to support this application. The new materials should properly address all physical property and chemical resistance requirements. In addition, the new packing materials should be direct replacement technologies to support backward integration into existing fire suppression systems during regular overhaul maintenance schedules. The development of direct replacement products ensures a seamless transition to the field without having to amend existing operational procedures or re-train personnel using these products in the field. In this proposal, METSS clearly defines the tasks that need to be performed to successfully address the program objectives.
