Abstract

Solar balloons are a simple and lightweight option for aerial exploration and meteorological data collection both terrestrially and on other planets. By using a lightweight material that absorbs visual light and emits low levels of thermal radiation, solar balloons behave similarly to hot air balloons but can ascend to much higher altitudes. Unlike hot air balloons, which use an onboard heat source to raise the temperature of the internal air, solar balloons generate heat by absorbing solar radiation, providing a free source of lift and eliminating the need for carrying an extra tank of lighter than air gas or fuel. Recently, solar balloons have gone through many technological advancements, ranging from design to material selection to controllability. This paper discusses the results and progress of new experimental solar balloon designs that explore various envelope sizes and material selection as well as a novel mechanical vent design on the top of the balloon to store and release hot air. By including a mechanical vent, the balloons can adjust altitude to enter regions of the atmosphere with different wind flows, which can lead to limited horizontal controllability of the platform.
