Last week, Elon Musk introduced his brilliant new rocket, the Starship MK1, to help achieve his goal of permanent settlement of Mars. The spacecraft will be a fully reusable vehicle designed for the long-term transport of cargo and passengers. Following his talk on the new advances, the 48-year-old spoke to Tim Dodd, host of YouTube channel Everyday Astronaut in which he discussed SpaceX's secret of success.
Subsequently, Mr. Dodd asked why the team? I decided not to use an aerospike, a kind of rocket engine that maintains its aerodynamic efficiency over a wide altitude range while consuming 25 to 30 percent less fuel.
Musk, however, had a surprising reaction last week.
: "I have often asked this question internally, for example: 'Guys, should not we use an aerospike? & # 39;
in a straight line possible.
"So you have your combustion efficiency and what percentage of the maximum theoretical combustion you are and how high your nozzle efficiency is, so you go in the O ther direction.
"With a traditional combustion chamber, you can achieve very high combustion efficiency because the bouncing molecules have time to unite and get things done.
"Then, if you strangle them somehow The throat gives them more opportunity to combine. "
However, Musk admitted that he was ready to change something and asked someone to prove the opposite.
He added, "We believe that we can hopefully come to 98.5 percent of the theoretical combustion efficiency due to combustion in full-flow stages.

"If anyone can show we're wrong, that would be great.
"If someone can say that there is a way to improve your design, this is a gift.
"The worst thing would be to use a stupid design and stick to it, that would be crazy. "
Musk claimed he would like to drop the design in favor of an aerospike if someone turns out to be wrong.
He continued, "I would love if someone could show how an aerospike is a smart move.
In this case, we just do an aerospike.
"Maybe the reason why they were not used is invalid because there was also a methane orbital engine.
"So there was neither one nor a full-flow combustion engine that saw the flight, nor was there a methane engine that saw the flight. certainly in a rocket scenario.
"I'm very confident that CH4 is the right fuel, but maybe Aerospike is right, but you have to show that your combustion efficiency is not compromised."
Musk previously explained how this theory is key was the success of SpaceX.
He said: " I believe I have learned many lessons on how to do things quickly.
"And then I passed those lessons to the SpaceX team, and just like SpaceX, they have an incredibly talented, hardworking team.
"In fact, I think there are sometimes too many talented people at SpaceX, we have too many talented people, we are entering the market.
"But there is this very talented group that works very hard and has to follow the general approach: if something takes too long, the design is not right.
"Therefore, the design needs to be changed to speed up the progress. "
