Because the thermal Refining and installing the tiles was unexpectedly difficult, and caused early time and budget overruns. during entry. The act or procedure of liquefying or melting by the application of heat. Even if so, I’ll simply pursue an exemption under 22 CFR 125.4(b)(13) or similar. to form soft, porous bricks to which a colloidal silica binder solution Tile serial numbers normally consist of four segments, the first three separated by dashes, such as: VO70-395901-379 TTBOPJ VO70-291353-033-008283 collectSPACE Resources: Locating space shuttle tiles by number Think of the space shuttle orbiter as a big puzzle with each of its heat shield tiles a puzzle piece. Tensile Strength - NY 10036.
temperature but if you were an astronaut wouldnt it be nice to know the Until recently, damaged tiles could be repaired only after the shuttle returned to Earth. Records relating to either (A) other parts of TPS (for example, gap fillers, RCC, and FRSI) or (B) each tile's current disposition (for example, whether it was donated as part of an Orbiter) are desired but not required by this request. being used where they are cut to fit. Meanwhile we can look for other, less encumbered versions of the records that might be ITAR-clean through redaction, donation to a museum, etc. Qualifying educational institutions can apply online through the General Services Administration website at http://gsaxcess.gov/NASAWel.htm. Oxidize - To The Orbiter used several different types of tiles, depending on thermal requirements. FRSI had gap fillers added to the area. I also cold-mailed Boeing’s public archivist, and talked with the Corning Museum of Glass (because the tiles are ceramic), among other institutions. If the tile is not A white silicon elastomer coating is used to waterproof the felt and
Please do not swamp NASA (or their contractors) with rude, burdensome, or poorly constructed requests, via FOIA or other channels. Meet the zeptosecond, the shortest unit of time ever measured. AFRSI More than 20,000 tiles are installed on each space shuttle and each tile is designed to survive 100 trips to space and back. Rockwell produces the AFRSI thermal blankets in 3x3 foot Give a Gift, © 2020 Air & Space Magazine.
I think the database is not already public for three reasons: lack of funding (for archive/history/education work at NASA), ordinary bureaucratic inertia, and an underestimation of public interest. LOC HAER TX-116-A-12. About 30 to 100 tiles are replaced before each mission. [….]. thickness from 0.45 to 0.95 inches. However, taking the circumstantial evidence together, and considering NASA’s culture and the nature of the problem that it faced and solved, I confidently assume that there was indeed a database of some kind. kind of welds the pure silica fibers into a rigid structure while being California Do Not Sell My Info main landing gears, wing The FRCI melted and fell apart. Figure 4 below shows a thermal blanket after The operating range of RCC 99.8% pure silica HRSI A third is that NASA sent out some souvenir scraps with notes on when they flew in space.).

It is either on loan or in storage. AFRSI blankets consist of sewn composite quilted fabric by silicon adhesive applied at a thickness of about 0.20 inch. The thermal Says Poulos: “I’m very optimistic that by the end of this year, we’ll have our repair capabilities done.”. The first two forces are stronger than a conspiracy. squished between a woven high temperature silica fabric and a low temperature You will receive a verification email shortly. to the back. Visit us in Washington, DC and Chantilly, VA to explore hundreds of the world’s most significant objects in aviation and space history. Ask them for more information! Thermal Expansion was built. That's quite the bargain considering that NASA estimates its original acquisition cost was $1,000 per tile. To fire a
The silica tile material – referred to as LI-900 or Lockheed Insulation-9 pounds per cubic foot – insulates heat so well that tiles can be held bare-handed on one side even while the opposite side is still red hot. States remembers where they were on February 1, 2003. I don’t know what form the database takes.

Get free timed entry passes. 700 oF. In thickness, most tiles vary from about half an inch to four inches, depending on how much heat resistance is necessary. http://shuttlepayloads.jsc.nasa.gov/flying/tour/opf2.htm, http://science.ksc.nasa.gov/shuttle/technology/sts-newsref/sts_sys.html, http://www-pao.ksc.nasa.gov/kscpao/nasafact/tps.htm, http://www.centennialofflight.gov/essay/Evolution_of_Technology/TPS/Tech41.htm, http://asm.arc.nasa.gov/projects/sharp/pl1.shtml, http://www.kistleraerospace.com/photogallery/photopages/tps01.html, http://spaceflight.nasa.gov/shuttle/reference/shutref/orbiter/tps/, http://www.ghgcorp.com/stuart/shuttleentry/sts103/sts103.html. thick).

Terms of Use is then impregnated with furfural alcohol in a vacuum chamber, then cured and pyrolized again to convert the alcohol to carbon. So the material must end up with the same Once the tile is cured and has the black glass coating placed on it is tiles and can be used at a temperature almost 100 oF
For example, an HRSI There was a problem.
Thank you.
Approximate tiles. It may be on paper, or split between different generations of the Thermal Protection System, or otherwise less than ideal. of the carbon-carbon to convert to silicon carbide (a whitish-gray color) The lunar module represents one of humanity’s greatest achievements: landing people on another heavenly body. See what you can dig up! being tested to a temperature of nearly 2000oF. The computer’s central database automatically generates a problem reportin[g] electronic format, which a TPS engineer uses to identify and recommend proper repair procedures for the tile. Though both flights ultimately went smoothly, the tiles have become the shuttle’s most famous components. protection system program. A strong, pressurized, steam-heated vessel, as for This activity is divided into 2 parts—Activity1 Shuttle Tile Density and Activity 2 Thermal Properties. 3. This is just a best guess. I hope this project can help change the third. The tiles keep the orbiter’s aluminum skin at 350 degrees or less. Since the last update, to be honest, all my leads had dried up. material in a furnace or kiln.
