Flight Dynamics Analysis,IMEDES Hypersonic Flight and Low speed descent. ARCHYFLOW analyses were performed starting with 3D trajectory simulations , including steady state and transient thermal analyses. Critical points along the hypersonic flight trajectory were further studied in in detail using CFD analyses

Material Analysis, temperature differences during hypersonic flight, yet be light enough for a reasonable mission, it has to be made of a high performance thin-film material or a laminate thereof. Such materials are tested as part of project ARCHIMATTER, which stands for ARCHIMEDES Material Testing and Research. It i

Transportation and Deployment System,ft‘s point of release. During interplanetary cruise, the ballute has to be kept well tempered and prevented from cold welding of packed envelope layers. Upon deployment, the system has to ensure that the ballute spacecraft properly unfolds in space and is held in position until fully inflated. Event

Mission and Spacecraft Design for Ballute Applications,t on mission design and vice versa. This is true even when compared to ordinary entry vehicles, because the deceleration altitude itself is of no concern, so long as no one gets hurt, and because relatively dense and small vehicles can tolerate a larger variation in the ballistic coefficient with co

Conclusion and Outlook, body (referred to as “ballute”) that is able to withstand the mechanical and heating loads during atmospheric entry. It could also be shown that a high performance ballute may be used to achieve a certain scientific goal by reaching altitudes otherwise inaccessible (which is a new concept introduce
