    Abstract
  • In respect for the thermal-dynamic simulation of stratospheric balloon, a comprehensive model that can calculate the ascending trajectoryand, the velocity variation as well as the film temperature distribution was proposed. Basic thermal characteristic and loaded forces of the balloon were analyzed.The dynamic and themotion equations were established to calculate the trajectory and velocity of the balloon. By dividing the balloon film into surface elements, the transient thermal equations of the film element was described to calculate the film temperature distribution.Measured wind data was introduced to simulate the thermal-dynamic performance at any moment during ascending and floating in real wind circumstances.
