Using Tank Pressure To Determine The Lift Of A Balloon, Sarah M. Biver
Using Tank Pressure To Determine The Lift Of A Balloon, Sarah M. Biver
2017 Academic High Altitude Conference
An important aspect of high altitude ballooning is accuracy regarding the calculation of helium inflation in the balloon. If the balloon is over-filled it will increase rapidly in velocity and burst too quickly to record data. If the balloon is under-filled the rate of ascension will be too slow or not at all. This paper highlights the importance of accuracy in helium inflation by examining a method that uses pressure to control the inflation of a high altitude balloon. On every helium tank there is a pressure gauge, which can be used to monitor the change in pressure. Using that …

Parafoil Recovery Of A High Altitude Balloon Payload, Chelsea Velasquez, Zachariah Benedict
2017 Academic High Altitude Conference
The Recovery Guidance System is a subproject of Iowa State Universities’ High Altitude Ballooning Experiments in Technology (HABET) group. The system is designed to avoid common hazards during descent including large area objects such as populated areas and roadways, as well as smaller objects such as trees in a field, with an accuracy within tens of meters. RGS provides guidance for the payload using a two servo system aboard the payload in conjunction with GPS and radio communication. Navigation will be handled by a mixture of GPS and video analysis. For guidance, only longitudinal and directional dynamics of the payload-parafoil …
