SpaceX experienced thermal protection Starship ship

In February a rocket engine Raptor, designed for Starship vehicle from SpaceX, has successfully passed the test firing. The company is moving ahead and, according to Elon Musk, in the coming days the ship will make his first test jump with one engine and then follow suborbital flights with three engines. Founder SpaceX video test showed a protective coating that will not allow the vehicle to burn in the atmosphere upon return to Earth.

The heat shield will be located on only one side of the ship and includes a coating made of hexagonal tiles. Selection of Engineers it fell on a form, because the image of the joints between the slabs leave no straight paths for the heated gases of the atmosphere. To protect the most areas will be applied is heated transpiration cooling method where methane and water will evaporate through the 10 micron openings on the back side of the coating and thereby cool the outer portion.

It is reported that the coating has been successfully tested at a temperature of over 1300 degrees Celsius - enough to survive the return to Earth. It is noteworthy that the ship will be ready for re-flight immediately after landing, and will not require re-repair.

transpiration cooling will be added wherever we see the destruction of the shield. The ship is ready to fly again immediately after landing.

The areas exposed to very high temperatures, will be revealed during the next test. Most likely, it is scheduled for this week, because the road near SpaceX area in the Dominican town of Boca Chica is blocked since March 18.
