Summary from the notice

PROJECT TITLE: Azimuth Rotary Joint Replacement LOCATION OF WORK: Vendor's facility. Supplies to be delivered to: Radar Operations Center 1313 Halley Circle Norman, OK 73069 NAICS CODE: 334519 - Other Electronic Component Manufacturing and the small business size standard is 500 employees. SET-ASIDE STATUS: Unrestricted DESCRIPTION: The purpose of this requirement is to replace Azimuth Rotary Joint used in the NEXRAD Weather Surveillance Radar WSR-88D. The current azimuth rotary joint design was introduced as part of the implementation of the dual polarized radar modification on all 160 WSR-88D (NEXRAD) radars operated by the NWS, DOD, and FAA. The current rotary joint design does not meet WSR-88D specifications for performance or reliability. Rotary joint failure symptoms/causes include missing wedges of data associated with its IF channels (Ch.3 and Ch.4), excessive air leaks associated with the use on non-airtight N-Type connectors, temperature sensitivity in the main stator rotor seal resulting in increased leakage in cold weather, and failure of various bearing assemblies attributed to heat-related hardening of bearing grease. The overall objective of this effort is to completely replace the existing inventory with a more robust design that meets or exceeds all WSR-88D specifications. This can be accomplished in one of two ways; (1) re-design of the existing rotary joint, or (2) introduction of a Commercial Off The Shelf (COTS) or modified COTS design. This contract will…
