Development of a 2000 Meter Aircraft Expendable Bathythermograph

Abstract

This final report summarizes the work for the development of an air launched 2000-meter expendable bathythermograph (AXBT) design. Probe design modifications were made to achieve a profiling depth capability of 2000 meters, following which a test program was implemented consisting of over-the-side testing, engineering air drop testing and laboratory analyses. It was found that the 2000 Meter AXBT design is a mechanically sound concept; however, a possible offset of temperature with pressure, making temperature exceed the specifications, was observed and requires further analysis. The results of the field and laboratory tests suggest that there may be an offset of temperature with increasing pressure. Mechanically, the design appears to be good, however, temperature offsets a high-pressure ranges suggest that the anticipated temperature resolution of 0.1 C was exceeded.
