Abstract
One of the technologies to make the future planetary exploration more flexible and valuable is a vehicle which can fly freely in the Martian atmosphere. Our group proposes a parafoil-type vehicle which has a flexible and inflatable wing. The parafoil can be packed compactly when a launch and cruising phase and can be deployed to a large aerodynamic device only when necessary, that is, flight in atmosphere. In previous study, we developed two type parafoils that are called heavy-type closed-canopy parafoil or right-type closed-canopy parafoil. The feature of these parafoil can be actively-deployed whenever we needed. However, these parafoil is too small lift-to-drag and to need too much gas volume to use the mars exploration. Therefore, in this study, we developed new-type parafoil which was reduced its gas volume to need to deploy it. That parafoil was obtained aerodynamic characteristics in wind tunnel test at the Jaxa 6.5m × 5.5m low speed wind tunnel. Moreover, the gas volume to need deployed it was investigated from deployment test.
