Abstract
In the field of high altitude ballooning the use of a zero pressure balloon has become common for its ability to stay at altitude longer than traditional latex weather balloons. This opens the doors for a new variety of high altitude experiments; however these balloons can often present challenges when it comes to flight control and termination. For environment and safety reasons it is ideal to bring the balloon and payload system down together. The purpose of this project is to create a reliable form of termination for zero pressure balloons with the long term goal of being able to accurately control the balloon descent rate. While many companies already use a similar system, this valve grants amateur ballooning groups a more accessible way of flying zero pressure balloons.
