ROSEMOUNT 858AJ115 HEATED AIR DATA PROBES FOR G550 AIRCRAFT

The National Oceanic and Atmospheric Administration (NOAA) is seeking to acquire two Rosemount 858AJ115 heated air data probes for its G550 aircraft. The probes are mission-critical components for the aircraft's atmospheric research mission, specifically for the measurement of three-dimensional wind vectors and "truth" pressure data. The acquisition is vital for NOAA to accomplish its mission of high-altitude tropical cyclone surveillance and environmental sampling. The required supplies must be compatible in all aspects with the existing G550 nose boom instrumentation system. • The Rosemount 858AJ115 heated air data probe is a highly specialized, low-volume instrument used almost exclusively by the international atmospheric research community. • The probe features a unique five-port hemispherical head geometry that allows for the simultaneous measurement of pitot-static pressure, angle of attack, and angle of sideslip. • The probe is essential for calculating 3D wind vectors in the turbulent environments of tropical cyclones. • Market research indicates that standard "brand name or equal" pitot-static tubes are designed for level-flight navigation and cannot maintain calibration or structural integrity at the high flow angles encountered during hurricane reconnaissance. • The required supplies must be delivered within 80 weeks from the date of award.
