Chapter 423 Why is recyclable rocket technology so difficult(2/2)
"Boss, because of our heavy investment over the past year, our 'lunar probe', that is, the lunar rover, has begun to be manufactured!"
"In addition, the first step in our 'lunar exploration plan', the mission of 'successfully launching an experimental satellite into lunar orbit and impacting the moon' has also entered the countdown."
"It is said that there will be a suitable time window for launch next month. If nothing happens, we will officially start the 'lunar exploration' plan!"
It's no exaggeration to say that.
The progress of the lunar exploration project team has far exceeded Hu Lai's expectations.
But when I think about it carefully, I don’t think it’s too surprising.
Since it began to invest heavily in the aerospace field, the salary packages provided by Phoenix Group have impacted all commercial aviation companies around the world.
There is no other reason.
Phoenix Group has given us too much!
In Hu Lai's words, as a latecomer, how can Phoenix Group attract people without high salary?
That’s right!
Under the money offensive, not to mention overseas, the outstanding top talents in domestic aerospace are directly boiling!
To be honest, for many senior engineers in state-owned enterprises, such as aerospace groups, their salaries are not high and they can only barely make ends meet.
Compared with overseas engineers in the aviation field, their results and income are somewhat far behind.
so……
With the high salary and Phoenix Group's excellent brand name, many senior engineers working in the "national team" have also switched jobs...
Not to mention the situation overseas, the aerospace engineers of Da Mao and Er Mao have not been doing well in recent years. As soon as they received the offer from the Phoenix Group, they set off overnight to fly to Yan Country, for fear that the Phoenix Group would regret it.
As for engineers from European countries, although they are also interested in salary and remuneration, what makes them most excited is the Phoenix Group's "lunar exploration plan" that is being launched...
To know.
Even if they are as powerful as the European powers, not all countries are willing to engage in or have the funds to engage in lunar exploration programs!
Such a project is a great temptation for engineers with ambitions and ideas!
After just over a year of fermentation, Phoenix Group has become the place where all aerospace engineers in the world most want to come, except Aramco!
Hu Lai said hello several times in succession.
Today's Phoenix Group is truly powerful.
After so many years of heavy capital investment, we are finally able to do some big things with our own R&D team!
After calming down a little, Hu Lai told Director Zhang the plan for the "Traveler Space Station".
Lao Zhang was not too surprised that Hu Lai proposed the idea of building a space station.
However, after hearing Hu Lai's vision for the space station, which in the future was to be built into something similar to a "space hotel" and "space travel", Lao Zhang suddenly put forward his own opinions.
"Boss, there is actually a problem that has been bothering us for a long time. You talked about the idea of a space station today, so I must raise it with you."
"That's 'recyclable rocket technology'!"
Um?
Hu Lai suddenly came back to his senses.
"Recyclable rocket technology" actually troubled the Phoenix Group when the "Tongtian Satellite" was first launched.
But there was no way at that time. Hu Lai didn't have enough system points, and there was no domestic company with this technology reserve. So even though rocket launches were expensive, Hu Lai still gritted his teeth and launched hundreds of "Tongtian Satellites"!
And now.
Indeed, as Lao Zhang said, if you want to realize your positioning as a "Voyager Space Station" and send passengers to the space station for space travel, the cost must be within a reasonable range.
First and foremost, launch prices must come down.
You don’t need to think too much about this, because SpeakX’s Falcon 9 rocket has already embarked on a commercialization path, and Phoenix Group now only needs to cross the river with SpeakX.
He frowned and said:
“Is ‘recyclable rocket technology’ really that difficult?”
"We've been studying it for so long and still can't grasp it?"
Lao Zhang shook his head slightly, then took out his mobile phone from his bag and said:
"This matter involves relatively professional technology, I'll let Pang Panglong explain it to you."
Pang Pang Long was the founder of the original "Zero Space" rocket. After "Zero Space" was acquired by Phoenix Group, Pang Pang Long became the head of the Phoenix Rocket Department.
"Alright."
After a while, Pang Panglong came to Hu Lai's office.
After Director Zhang briefly explained the situation, Pang Panglong introduced:
"Boss, actually the principle of 'recyclable rocket technology' is very simple, not to mention complicated."
Hu Lai was slightly surprised and continued to listen.
"For now, the mainstream launch vehicles in various countries around the world are multi-stage rockets."
"The mission of the first-stage rocket is to launch the rocket to the 'Karman Line' (elevation 80-100KM), which is the dividing line between space and the atmosphere."
"After reaching this position, the first-stage rocket will be useless. In order to reduce the weight, the first-stage rocket will be separated, and then the second-stage rocket will be ignited. The second-stage rocket will carry the payload through the atmosphere and enter space at the fastest speed in the universe.
"
"The separated first-stage rocket casing and engine will fall from an altitude of 80km and land in the designated area."
"'Recoverable rocket technology' actually recovers the first-stage rocket, which is the part that we often see on TV that is ignited on the launch pad and then lifted off."
Hu Lai nodded and motioned for Pang Panglong to continue speaking.
"Under normal circumstances, the first-stage rocket will fall directly to the ground heavily. After falling 80 kilometers, no matter how good the material is, it will be useless."
"The 'recoverable rocket technology' now used by SpeakX actually calculates the distance between the rocket and the ground, starts the rocket reverse thrust at a suitable distance from the ground, and offsets the gravity of the free fall, so that the first-stage rocket lands smoothly."
"Among them, whether it is the calculation of starting rocket reverse thrust, the calculation of the remaining fuel in the first-stage rocket, or even the attitude problem, it is a small problem. We can do it through a large amount of simulation data, or after the real rocket is launched.
improve!"
"So, the principle and technology are very simple."
"The reason why we can't achieve it now is that we don't have the same rocket engines with high reliability, small size, and high thrust-to-weight ratio like them."
"Rocket engine?"
Pang Pang Long nodded:
"That's right."
"Rocket engine!"
