The Internet has a classic spray sentence - you XX spiral to heaven. I didn't think much before, but recently Tony saw something and found that this sentence actually contains a lot of scientific principles. Because a company called spinlauch has developed a new rocket launching method that is said to be the most efficient at present This way is very straight ball, simply put, is to let the rocket spiral into the sky
Perhaps in everyone's impression, the rocket launch is as follows:
First fix the rocket with a launch pad, then all ground personnel are in place and start counting down to 10.
Then it ignites and uses the reaction force generated at the moment of chemical combustion to push the rocket vertically into the air Then turn through the booster and program to enter the predetermined orbit outside the atmosphere.
In the whole process, the ground personnel should always monitor the flight status and synchronize the progress. For example, when China's beidou-3 geo-3 satellite, someone can always report that "XXXX telemetry signal is normal".
Finally, the whole launch process can only be completed after seeing the successful separation of the satellite and the rocket (the separation of the satellite and the rocket).
But the spinlauch mentioned at the beginning broke our sense of ritual of the rocket slowly taking off——
It built a launcher that looked like a blower and could swing the rocket directly
The large transmitter has a vacuum inside, and a booster like a clock is built in the center, which can create centrifugal force through high-speed rotation.
When the kinetic energy accumulates enough, you can shoot the rocket along the "chimney" on the side.
Loosely speaking, the traditional rocket launch started like shot put, but spinlauch played hammer throw with one hand.
Using high-speed centrifugal force to increase the initial kinetic energy, it can fly fast and far naturally in theory.

Ignition launch ▼
Not long ago, they just finished their eighth test launch.
The video of spuuch was launched for the first time on YouTube last year, and it seemed that it was the first time that spuuch introduced itself.
But because the first video didn't show much practical operation process, netizens couldn't help but doubt it.
After all, the company has made a lot of investment. The video may be used to fool investors, or maybe...
Many netizens also published some technical questions
You know, a land rocket can be as light as dozens of tons and as heavy as seven or eight hundred tons. It doesn't need to be boosted by chemical ignition. It just depends on strength to fly. It sounds a bit absurd.
In addition, in the vacuum centrifugal environment, the effect of force will become quite terrible. It is difficult to ensure that rockets or satellites will not be "flattened" during launch.
In "me and my motherland", there is a natural eight times speed
But rockets are far more than that ▼
The point is, there's more to the problem.
Rocket launch involves complex levels and huge data. Each small step is related to success or failure. A video doesn't mean anything at all.
Therefore, some netizens simply opened the semi mockery mode in the comment area. For example, this big brother said:
"Regardless of the Rockets, your video should be able to participate in an Oscar. It's a good shot!"
This makes spinlauch's head full of pressure and doubts from the outside world.
Fortunately, they sent another video a few days ago, which can be regarded as a way to win back their breath.
Because spinlauch finally installed a camera on the rocket, so that everyone can clearly see the whole launch process
It can be seen that the rocket in the video is indeed spiraling all the time, and the flight distance is also considerable.

For comparison, let's show you the first angle of view of SpaceX starship sn15 launch.
This is the traditional land launch. It's obviously not so dizzy.
Mainly look at the ▼ in the lower right corner
The launcher demonstrated by spinlauch, called a-33 suborbital mass accelerator, can launch at a speed of 1600 km / h and fly to an altitude of 7620 meters.
This level is a little far from the 16000 + km / h and 10000 meters altitude of the traditional single-stage rocket
But they said the demonstration used less than 20% of the power of the a-33
Even, they will soon have a full-size L100 orbit, which is three times larger than that in the video. They can launch a 200 kg satellite into the predetermined orbit at the speed of 8000 km / h. There is no problem with normal use.
The reason why this effect can be achieved is actually related to the material, size and weight of the rocket (it's too heavy to throw).
Instead of making rockets, these people are more like making a "special missile".
According to spinlauch's official website, they selected carbon fiber to make the rocket, which is not only strong enough to resist high gravity environment, but also much lighter than stainless steel and other metal materials.
In addition, there is no fuel for land launch, so the weight of the rocket will be greatly reduced, and naturally there will be no need for a big guy with hundreds of tons to play
If this thing is really done, the company may be able to count money lying down in the future.
Even if we launch rockets in the future, they may be as efficient and standardized as we fly
Various technology companies, such as Google, Apple If you want to launch a satellite, just queue up and place an order. Spinlauch can launch one by one.
Because the launch process is fixed, only customized launch vehicles are needed. It runs like a large sniper gun. Both time and cost will be greatly reduced.
NASA in the United States will not miss this opportunity.
Just a few days ago, I immediately sent a contract to spinlauch. It is expected to cooperate this year and put it into real use.
But then again, rocket launching is not just about shooting it out.
After all, the rocket is only a means of transportation. The goal of the mission is to deliver the payload - the satellite, the "passenger" safely
This violent operation is rotating and jumping. How to ensure the safety of the satellite during Disintegration? Spinlauch's method is not the same as the propulsion method, which lacks the dynamic regulation of the control system during the launch process.
In case of an evil wind that day or earth perturbation interference, how can we ensure that the satellite enters the predetermined orbit 100%?
Spinlauch hasn't given a more specific answer to the above question, and we can only quietly look forward to the follow-up.
However, this new technology and idea is still very worthy of affirmation
Because after exploring space for so many years, mankind has thought of various methods to reduce the cost and risk control of launching rockets.
Although fuel propelled Rockets have a wide range of applications and higher bearing capacity, they do consume resources and are accompanied by certain risks. One more choice is definitely not a bad thing.
Now Tony hopes that a low-cost manned scheme can be developed in the future
After all, spinlauch's centrifuge launch is obviously not suitable for carrying people. No one can suffer from its rotation method.
At present, the cheapest choice is estimated to be Musk's SpaceX——
Space ten day tour, with a single ticket price of 350 million.
Those who can't wait can try this first.
