High-Performance Atmospheric Measurement System Using Kites and Blimps

We propose to use the results of our Phase I proposal to produce a prototype system capable of advanced measurements under a wide range of conditions. This proposal involves the development of all three primary components of the complete system:instrumentation, winching, and lifting platforms. We will add a fast response, three-dimensional hot-film sensor to our Phase I instrument to make wind vector measurements to scales smaller than 1 cm. A specialized winch system will be designed andconstructed to allow for optimal operation with both kite and blimp platforms in a highly portable, self-contained unit. Kites and tethered balloons will be employed as the lifting platforms for the system. Existing single line parafoil kites will bemodified to limit the maximum tension they produce in high winds, and commercial advertising balloons will be employed in light wind conditions to allow system operation under a wide range of wind speeds. The entire atmospheric measurement system will betested at various stages of its development at White Sands Missile Range, or another suitable site, and measurement results will be compared with existing instruments and remote sensors available at that site.
