Abstract

This paper discusses the validity of pressure independent first-order thermal models for high-altitude balloon gondolas subjected to short duration flights. Thermal system identification results performed on a test gondola in a vacuum chamber at varying pressures are presented. These results indicate that the lumped parameter of thermal resistance changes significantly with pressure. Though this dependence on pressure may make a difference on long-duration flights, the validation results that are presented in this paper indicate that pressure independent models are capable of responding to within a few degrees of the actual temperature on short duration flights.
