Emma Jonson What were the space shuttle tiles made of?
silicon material
They are made up of what is called a porous silicon material that is very light and extremely heat resistant. There are two main types of tiles, one a black-coated tile called HRSI for High-Temperature Reusable Surface Insulation tile. These tiles can withstand up to 2,300 degrees F (1,260 degrees C).
What type of material was used to protect the space shuttle from the heat and cold while in space?
Much of the shuttle was covered with LI-900 silica tiles, made from essentially very pure quartz sand. The insulation prevented heat transfer to the underlying orbiter aluminium skin and structure. These tiles were such poor heat conductors that one could hold one by the edges while it was still red hot.
Why is a thermal protection system important for a rocket?
During re-entry, the Orbiter’s external surface reached extreme temperatures— up to 1,648°C (3,000°F). The Thermal Protection System was designed to provide a smooth, aerodynamic surface while protecting the underlying metal structure from excessive temperature.
Why is the space shuttle black and white?
The tiles exposed to reentry temperatures of up to 2,300 degrees Fahrenheit, such as those on portions of the belly, are given a protective coating of black glass. Black tiles work by reflecting about 90 percent of the heat they’re exposed to back into the atmosphere, while the tiles’ interior absorbs the rest.
What was the thermal protection system on the Space Shuttle?
The Space Shuttle thermal protection system (TPS) is the barrier that protected the Space Shuttle Orbiter during the searing 1,650 °C (3,000 °F) heat of atmospheric reentry. A secondary goal was to protect from the heat and cold of space while in orbit.
What kind of tiles are used in space shuttles?
The tiles used were based on work carried out by the Lockheed Missiles & Space Company who had a patent disclosure which described a reusable insulating tile made from ceramic fibers which could be used during re-entry as a guard against high temperatures.
What kind of insulation is used on a Space Shuttle?
The nose cap thermal insulation ues a blanket made from ceramic fibers and filled with silica fibers. HRSI or FRCI tiles are used to protect the forward fuselage from the heat radiated from the hot inside surface of the RCC.
How is the thickness of Space Shuttle tiles determined?
After being sinteredthe block is ready to be cut and machined into the required dimensions. HRSI tiles vary in thickness from 1 to 5 inches. The thickness of each tile is determined by the heat encountered during re-entry. In general, the tiles get thinner as you go from the front end of the orbiter to the back.
