Abstract

High Altitude Ballooning and The Effect of Temperature on Balloon Ascent Rate.

Christopher Young

High-altitude balloons are unmanned balloons, usually filled with helium or hydrogen, that after release, ascend into the stratosphere, generally attaining an altitude of between 60,000 to 100,000 feet. The balloon payload includes scientific experiments on organisms, equipment to study radiation, temperature, ultra- violet radiation, and pressure. The balloon flights and experiments are logged by means of video devices and are tracked from the ground through multiple tracking devices. The effect of temperature on the ascent rate of the balloon could change how the balloon expands as it ascends, affecting the burst height. The data collected from multiple different sensors will be altitude, time, and temperature. Once all of the data is collected, the ascent rate will be calculated, then a graph of ascent rate vs temperature will be made. With the graph being complete, the ascent rate will be compared to different temperatures to see if there is a correlation.
