The Naval Surface Warfare Center, Corona Division is requesting information, comments and questions regarding interest in a commercial or modified commercial Air Data Calibrator Pressure Standard solution, hereafter referred to as ADC pressure standard, that is capable of measuring the pressures that are typically associated with the support of air data related support equipment. Typical parameters requiring support are as follows: altitude workload that ranges from a minimum of -1500 to 80,000 ft (31.5765 to 0.8154 inHg abs), minimum air speed workload ranges of 20 to 1000 Knots (0.019 to 73.546 inHg differential pressure), altitude rate workload ranges of 0 to 30,000 ft/min, and leak rate testing equivalent to an elevation of 50,000 ft (3.4246 inHg abs) with a leak rate of less than 100 ft/min at the accuracy ranges specified in the draft technical specifications listed below. The ADC pressure standard will be used on shipboard and shore-based facilities and must conform to the CLASS 3 requirements as listed in MIL-PRF-28800. Equipment will also be subjected to operational conditions aboard both military and commercial land, sea and air vehicles during periods of operation, transportation and storage.
