Building the Atmospheric Model
The atmosphere on Uranus has been studied by many different scientists. Using frequency occultation, scientists can gather data around the outer thermosphere but getting accurate data below pressure altitudes of 1 bar are more difficult. Many assumptions and extrapolations combined with telescope observations have produced a variety of different atmospheric models. In order to design an aircraft that will fly on Uranus, an Atmospheric Model must be agreed upon. Using the similarities found in different models and consulting with Dr Raymond Lebeau, who has researched and published a few papers on Uranus’s atmosphere, a decided model has been assembled. During its mission, the UAV will be flying in an atmosphere comprised mostly of Hydrogen and Helium with pockets of cloud formations comprised of Methane and liquid water. The wind velocity varies widely and is vary latitude oriented but wind gusts within the atmosphere are expected to be in the range of 20cm/s. The figures below show the velocity profile with respect to latitude and the temperature to pressure ratio.
