Development Plan 3rd imernazronai Pianezary Probe Workshop Anavyssos Amos Greece June 27 7 July 1 2005 Why an Inflatable Aeroshell Advantages over rigid aeroshell DeflatedStowed the aeroshell is a small modular component thereby allowing Increased payload volume fraction in the launch vehicle shroud Access to the payload afterthe launch vehicle integration System duplication between the cruise stage and entry vehicle Delivery of more payload mass to the surface Inflated the aeroshell can achieve sizes much largerthan those attainable by rigid aeroshells allowin Rapid highaltitude deceleration for access to high altitude landing sites A less hazardous thermal environment for the total entry system Technical Challenges Flexible Structure Unpredictable drag performance Aero structural dynamic instability Durability Reliability Aerothermal heating 3rd internatronai Planetary Probe Workshop Anavyaaoa Attrca Greece June 27 a July 1 2005 altitude km Direct Ballistic Entry
