Among the tweets of Tesla Deluge and The Boring Company, the founder, CEO and SpaceX rocket designer, Elon Musk, launched the latest news on the Big Falcon Rocket "Starship. "
Although maintaining the original name of the Big Falcon Rocket could have generated a controversy in which a rocket was named (the meaning behind the "F" caused a debate), the latest Musk tweets touched on something much more important: what this new rocket to be he was part of.
In the case of Starship, which has recently been said, this material appears to be stainless steel. While stainless steel is nothing new, having been invented in 1913 by Henry Brearly. Musk he pointed out The positive aspects of the material in a tweet on December 24, 2018: "The full stainless steel strength / weight of Crio is slightly better than carbon fiber, the room temperature is worse, the high temperature is much better. "
What type of paint has Musk selected to cover the new massive vehicle? Cap. "The skin gets too hot to paint. Stainless steel mirror finish. Maximum reflectivity ".
As for the temperatures a vehicle finds when it returns to the Earth's atmosphere (NASA's fleet of ferries now retreated with ends of up to 3,000 degrees Fahrenheit / 1,649 degrees Celsius), it is essential that the your protection is up to date. For this task, it seems that Starship could use a regeneratively cooled thermal shield.
The heat boards used in the NASA space launch fleet (designed and built by Rockwell International) were designed to last the planned life of each orbiter: 100 missions. The shuttle also used thermal blankets and other systems and procedures to reduce the stress of the interface with the atmosphere.
The thermal shields used in previous spacecraft have been mainly for single use. The ablative calorific shields, for example, were burned, taking fire with it. This type of protection system was used in NASA's Mercury, Gemini and Apollo ship.
Musk discussed the regenerative protection-cool Starship by indicating: "The leeward side does not need anything, the side of the wind turbine will be the activity cooled with residual liquid methane (crio), so it will appear liquid silver even on a hot side. "
SpaceX has benefited from materials developed by NASA for thermal protection. The most obvious is PICA-X, which is a derivative of the thermal shield of the Phenolic Impregnated Carbon Ablator (PICA) of NASA.
In the same way that the launch of NASA, the Starship rocket engines must be protected during the critical period of re-entry. Musk seemed to be considering the matter in one tweet Christmas in response to the questions asked: "No, the Raptors must be protected during the atmospheric entrance. Although maybe not … " Musk said that you will use three raptor engines for the "hopper" flight test that could already take place in 2019.
Starship is a vehicle that has undergone several changes in the design that generated a question about how late design changes seem to allow the company to produce Starship faster. Musk said he will address how this process works sometime during the March / April period. He also stated that these changes could provide a 60 percent probability that Starship could be in orbit as soon as 2020.
As Amit Malewar of Tech Explorist pointed out, the Big Falcon Rocket system would use a 219-foot (67m) high rocket rocket that Musk called "Super Heavy."
