  1. William Yeong Liang Ling3/20/2008PropulsionDevelopmental History of the Balloon ModelThanks to all who contributed along the way! AAE 450 Spring 2008 Propulsion

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

  3. Final Model • 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) AAE 450 Spring 2008 Propulsion
