AAE 450 Spring 2008 Preliminary Development Propulsion 1.Scaling of pre-existing studies. (Credit: Jerald Balta) 2.Derived a buoyancy equation. 3.Derived equations to determine balloon requirements. 4.Discarded balloon gondola (complexity and cost). 5.Designed simple disposable gondola. (Credit: Sarah Shoemaker, Jerald Balta) 6.Returned to physics model to perform in depth analysis.

AAE 450 Spring 2008 Final Model Propulsion Customized gondola. (Credit: Sarah Shoemaker, Jerald Balta) Commercial balloon costs from Aerostar. (Credit: Jerald Balta) Code that determines size requirements of the balloon. Physical simulations in x-y-z planes Able to determine rise velocity, acceleration and time ~ 2 hours rise time depending on gross lift off weight Able to determine drift distance taking into account random gusts (Wind model: Allen Guzik, Kyle Donahue) ~5,200m depending on gross lift off weight (varies by less than 200m)
