LAURA Aerothermodynamic Computations for Space Shuttle Columbia STS-107 Baseline and Damage Scenarios

摘要: *† Computational simulations for nominal and damaged Shuttle Orbiter configurations were performed in support of the STS-107 Columbia accident investigation. baseline computations both hypervelocity flight low-enthalpy wind tunnel conditions contributed to investigation by providing information a variety damage scenario analyses. Computations at just prior peak heating trajectory point two scenarios involving missing wing leading-edge reinforced carbon-carbon (RCC) panels. The initial modeled with an approximate RCC panel 6 determine whether could be source anomalous temperatures measured on side fuselage during reentry. Results from that computation showed augmentation up 5 times level smaller front OMS pod. This is consistent thermocouple resistance temperature detector sensor outputs re-entry which revealed off high early trajectory. A second 9 included ingestion flow into outboard channel behind For this scenario, maximum was less than 3 value location moved aft confined nearer juncture previous case. Near predicted remainder fuselage, lower surface As solution required supersonic large accompanying mass ingestion, it not realistic model penetration through spar structure. may, however, representative after would data where pod sensors observed decrease later
