Titan-GRAM Model vs Cassini-Huygens Data Aerocapture min alt Aerocapture Minimum Alt Range Aerocapture to Orbit Alt Range Titan-GRAM conservatively bounds the density observations from HASI and INMS Ref.: Justh and Justus, “Comparisons of Huygens Entry Data and Titan Remote Sensing Observations with the Titan Global Reference Atmospheric Model (Titan-GRAM)” 10
! ! ! ! ! ! ! Titan Aerocapture Technologies - Ready! Enabling Technologies - No new enabling technology required Strongly Enhancing Technologies Aeroheating methods development, validation • Large uncertainties existed at time of analysis, further work and Cassini data all but eliminated TPS Material Testing • TPS materials were not tested against then-expected radiative heating at Titan; testing was done AND radiative environment reduced significantly in models Atmosphere Modeling • Model validated against Cassini/Huygens data Enhancing Technologies Aeroshell lightweight structures - reduced aerocapture mass Guidance - Existing guidance algorithms have been demonstrated to provide acceptable performance, improvements could provide increased robustness Simulation - Huygens trajectory reconstruction, statistics and modeling upgrades Mass properties/structures tool - systems analysis capability improvement, concept trades 11
