Vol 2 Chapter 944: The glory of aerospace technology
"It is not impossible. Haoyu Technology has always been in close cooperation with the military, and is engaged in the research and development of many major weapons and equipment projects. Therefore, it is no surprise to participate in such projects." "Impossible, I I think it should be related to our space station, similar to some experimental cabins."
"Speaking of which is possible, it may even resemble a cargo ship."
"Yes, I prefer this kind of cargo spacecraft. After all, the operation and subsequent construction of the space station also requires sufficient and cheap capacity. If this kind of retractable launch vehicle is successfully launched, it will further reduce the cost of launching, thereby increasing more The experimental equipment is transported to the space station."
"I'm going, this is a job with the country."
"I think it is a good thing. The rise of private aerospace companies is conducive to promoting the development of the domestic aerospace field. From an overall perspective, it is very beneficial."
From the perspective of long-term development, the advantages of introducing private enterprises into the aerospace technology industry, especially the important aerospace technology industry, outweigh the disadvantages. However, the actual implementation has to be considered. After all, the rocket and aerospace industry has been state-owned for a long time. This sudden opening to private enterprises is bound to cause some problems, so we must be cautious.
I don’t think it can be a cargo spacecraft. Whether it’s the Jianmu-1 low-cost disposable rocket or the Jianmu-2 retractable rocket that will be launched soon, its carrying capacity is very limited. Take this slightly stronger Jianmu-2 for example, its low-Earth orbit carrying capacity can reach 4.2 tons, and the sun-synchronous orbit can reach 2.3 tons.
The average cargo spacecraft weighs seven or eight tons or even more than ten tons, so it is unlikely that this is the case.
I prefer what my brother said above, it may be a certain experimental section of the space station, or it may be an experimental vehicle like X37B.
No, the low-Earth orbit carrying capacity of 4.2 tons is still very objective. And these are not important, the important thing is cheap. If the cost of carrying this rocket is low enough, then more launches are enough. Moreover, the tasks are more scattered and the reliability is higher.
That’s right, you can’t ship it twice in one shipment, and ship it in four times. Anyway, with this retractable rocket, the launch cost is indeed cheap enough.
666, although the ants moving house looks relatively small, the power they gather is also very terrifying.
I still prefer a certain type of spacecraft.
……
Ten minutes to prepare!
The voice of the broadcaster dispatched by the command center came from the speakers in the observation station.
coming. Wu Hao, Erma and the others looked at each other, and then looked at the rocket standing next to the launcher in the launch site.
And Wu Hao and the others also ended the chat, staring at the rocket figure displayed on the big screen, and meditating on the countdown number in their hearts.
"Five minutes to prepare!"
"The countdown is one minute to prepare, fifty seconds, forty seconds, thirty seconds, twenty seconds!"
"Ten, nine, eight, seven... One, light up, take off!"
Boom! Although they were far apart, Wu Hao and the others in the observation station could still hear the huge roar of the rocket after it ignited.
I saw bursts of flames and dust blowing from a white rocket in the blue sky. Under the jet of these orange-red flames, the rocket slowly began to lift off.
"The rocket successfully ignited,"
"Enter the program to turn."
"The program turn is complete!"
"The ground-based optical observatory reported that the rocket was flying normally and the telemetry signal tracking was normal."
Papa papa... everyone present burst into applause. But now everyone hasn't relaxed, because the rocket has just taken off, and it is not known whether it will succeed.
The rocket flew higher and higher, and began to draw a white line of smoke on the blue sky.
Okay, finally the launch was successful. Lao Ma couldn't help but praised: "I have heard that the moment of rocket launch is still very shocking. I still don't take it seriously. I thought it was like that.
Unexpectedly, after I was on the scene today, the impact of the rocket at the moment of launch was not stronger than others.
Amazing! "
"The rocket flies normally, and the telemetry signal tracking is normal."
The little Ma on the side looked at the invisible rocket in the sky, and couldn't help but sigh: "This kind of impact and shock that hits the sky directly is really impressive. Humans are really terrible. Fly the behemoth with a take-off weight of more than two hundred tons, and not only fly, but also fly into space."
Technology is the primary productive force, this sentence is not for nothing. Lao Ma said with a smile.
The first and second stages of the rocket are separated, and the second stage is successfully ignited! Everyone was chatting, and suddenly there was an announcement.
The fairing is separated!
Papa papa... There was another round of applause at the scene.
You should know that the separation of the fairing usually means that the rocket is about to reach space.
It's alright, now let's watch the landing of the first-level arrow body. Wu Hao looked at the blue sky and the cloud line that was about to dissipate.
Guide the parachute to throw, the main parachute throws!
The base optical observation station reported that the three decelerating umbrellas of the first-level arrow body have been fully extended and are in good condition!
Papa Papa...
Amidst applause, Wu Hao and the others have already seen the three red and white speed umbrellas in the sky. However, because of the distance, as far as the eye can see, the huge deceleration umbrella is regarded as a small point.
However, the three parachutes opened, which already means that the entire landing process is half completed.
"The Meteorological Observation Team reported that there was an enhanced convective weather at an altitude of 5,000 to 8,000 meters~www.readwn.com~ The wind exceeded the warning range, please be prepared accordingly."
Strengthen the attitude adjustment, closely calculate the landing trajectory, and ensure that the first-level rocket can successfully land on the pre-marked landing field.
As the main retarder's field of vision grew wider and wider, everyone on the ground finally saw the rocket's movement.
It can be seen that the rocket did not tilt, but fell in a parabolic direction.
And the grid plate on the rocket body is constantly adjusted to ensure the correct posture during the descent process.
It's the final stage! Seeing the sight of the three deceleration parachutes widened, everyone understood that this had reached the final landing stage.
If the rocket engine can be ignited and started, then the first-stage body of the rocket can land safely.
But if the ignition fails, then the entire first-stage rocket may be like a missile, and the people will fall directly on the field.
One thousand acres, the rocket fires once!
Following the broadcast, the engine at the bottom of the rocket body began to emit a large amount of flames and smoke instantly.
The engine is successfully ignited and the speed is decreasing.
Wu Hao and others at the outdoor observation station can also clearly see that the rocket's landing speed has been significantly reduced.
One hundred meters, fifty meters, ten meters...
