Abstract

The AFOSR Multidisciplinary University Research Initiative (MURI), "Integrated Measurement and Modeling Characterization of Stratospheric Turbulence”, is in the second year of a 5-year effort to resolve significant operational issues concerning hypersonic vehicle aerothermodynamics, boundary layer stability, and aero-optical propagation. In-situ turbulence measurements along with modeling will quantify spatiotemporal statistics and the dependence of stratospheric turbulence on underlying meteorology to a degree not previously possible. Data from high altitude balloons sampling at 1-2 kHz is required to characterize turbulence to the inner-scale over altitudes from 20 to 35+ km. The use of controlled descent systems allows high resolution unperturbed measurements during the descent, while data retransmission out of the altitude range of interest improves the percentage of losses during the descent part of the launch. This poster presents the development of a standard balloon bus and controlled descent units based on COTS components to achieve high telemetry rates that potentially enable sub-cm scale sampling. Both single and double balloon configurations are investigated while maintaining a suitable cost for “mass production”, and multiple ground stations are used to analyze Single Payload Multiple Ground Stations (SPMGS-SIMO) and Multiple Payloads Multiple Ground Stations (MPMGS-MIMO) strategies for multi-point and multiple follow-on launches.

Low Cost High Altitude Balloon System Configurations with High Data Throughput on a Slow/Controlled Descent
