Web3. apr 2024 · After Columbia made the first-ever shuttle flight in 1981, it was found that the spacecraft had been bombarded by tank foam during its ascent. Over 300 tiles had to be replaced, and engineers remarked that had they known the tank would toss so much foam, they would've been hesitant to clear Columbia for liftoff. WebSimplifying Assumptions Initial temperature of all tiles is 16 OC regardless of location The heat flow is modelled in 1 dimension only (the 5cm thickness direction) The properties of the tile are assumed to be uniform and isotropic Specific heat, density and thermal conductivity remains constant throughout the tile depending on the material …

WebTwo ceramic HRSI tiles were analyzed in this investigation, one being flown on mission STS 46 and the other unflown (pristine condition) (figs.2, 3). With the retirement of the Space Shuttle program, the unflown single tiles were distributed to museums across the country for educational purposes, however without supportive technical information.

WebOn Columbia about 3400 tiles were densified to improve adhesion. The bond strength requirement was 125% above the maximum predicted aerodynamic load conditions. These conditions varied across the bottom of the Orbiter during launch and during EDL. 3400 tiles were pull-tested at 2 psi. 6300 tiles at 2 to 6.5 psi. WebThe missing tile had been located over the aluminum mounting plate for an L-band antenna (one of six, part of the Tactical air navigation system (TACAN) landing system), perhaps preventing a burn-through of the sort that would ultimately doom Columbia in 2003.
