This is how black technology should be used

Chapter 135 Single-stage orbital spacecraft plan!
"Hiss, I don't know if I don't check, I'm shocked when I check!"

"Niu Pi, why do I feel that times have changed?"

"Times have changed a long time ago, we just didn't realize it."

"With so much news coming out at once, the powered exoskeleton should be fully put into the market."

"For sure, otherwise it must have been well hidden, and now that it is released, it definitely means that there is a better one!"

"Actually, the previous powered exoskeleton can basically be used. Raytheon Company in the Freedom Federation has a single soldier exoskeleton. Except for the smaller battery, it seems to be ready for actual combat. If it is directly connected to the wire, it is enough to be used in the military. Working in the back office."

"When it comes to battery issues, we have to talk about practical technology's graphene batteries. It is probably related to the fact that domestic powered exoskeleton technology can be put into actual combat."

"Yeah, why didn't I think of that."

"Actually, powered exoskeletons have been used in the medical field for a long time, but the movements are slow and there is no need for strenuous activities. I don't care about the battery life, and it doesn't even matter if it is always connected to the wire."

"Speaking of powered exoskeletons in the medical field, I remembered the video of the exoskeleton in the hospital. Its performance was very good. I don't know if it has anything to do with the actual combat exoskeleton that is showing up now?"

"Hey, I also remembered. The exoskeleton video in the hospital was quite a sensation at the beginning, but there was no follow-up, so the popularity dropped. Couldn't the follow-up be this?"

"I don't know, it's hard to say, but now it's all news about the army and the police department, no civilian news?"

"That's right, according to the current situation, the civilian hospital should have appeared, right?"

A test video of the future 2PM mobile phone not only allows people to better understand the purpose of the future 2 series mobile phones, but also exposes the power exoskeleton to people.

But since it is brightly displayed, it is for people to see, even for the opposite side to see.

So the fact is that the guy on the other side of the sea is indeed more excited than the people in Fanxing Country.

Of course, the "excitement" on both sides does not mean the same thing.

Free Commonwealth.

Ministry of Defense.

"Snapped!"

The dark-skinned Secretary of Defense Austin slammed a folder on the table and asked Thomas, the director of the Strategic Intelligence Center standing aside: "What's going on?!"

In fact, Thomas, who was called over, looked puzzled, but after he opened the folder, he said in surprise: "There is such a thing!"

"Snapped!"

Now Austin slapped his hand on the table, and he said loudly: "Thomas, you are the director of the Strategic Intelligence Center, your task is to collect intelligence and report to me, not me, the Minister of Defense, to report to you! "

Seeing Austin in this state, Thomas hurriedly argued: "Mr. Minister, we will investigate with all our strength..."

"I don't want an explanation right now, I just want detailed information!"

Thomas sweated down.

The international situation during this period seems to have stabilized a lot to outsiders, but only they know that the current international situation seems to be stable, but in fact it has changed drastically in private.

There is a sense of urgency that a hurricane is coming.

The domestic policies of the federation are changing, and major companies have joined the latest "return to the moon plan". It seems that they are brought into the management scope of the federation, but in fact, their respective rights are constantly increasing.

But in fact, the current situation is not easy to handle, because the current citizens are not the same as when the first manned landing on the moon.

You say you want to go to work in a factory, but how can you feel comfortable going to work for zero yuan?

If you want to build a new factory, a group of nature protectors must surround the gate.

You want him to... oh no, she, it, TA...

Well, it’s not easy anyway, now playing various sports is more promising than going to work.

And the outside of the Federation is the battlefield of intelligence agencies.

At the beginning of the great change in Fanxing's country, the relevant intelligence network began to tilt towards Fanxing's country.

But later the big groups in the Federation stood up, and the competitors on Fanxing's side also stood up. This is not what the big groups in the Federation want to see.

It just so happens that the intelligence resources of the Federation are tilted towards the stars. Big groups need information, and their actions are much more generous than the Federation, so the direction and focus of intelligence acquisition quickly changed...

Cough, make money, not shabby.

So it is normal to have neglected places.

It is not even necessarily ignored, but not uploaded in time after collection.

The main reason is that there is no relevant large group to buy the latest information in certain aspects. If it is passed back immediately, they will not be able to make money.

Of course, they are the intelligence network of the Federation after all, and some key information still needs to be paid attention to. Now Thomas must immediately show the information on the individual powered exoskeleton. He must have no choice, so he can only divert his attention.

"Mr. Minister, I will give you the information related to the powered exoskeleton as soon as possible, but I have an important information to report to you now!"

Thomas said seriously.

Austin squeezed the space between his eyebrows, leaned back on his seat and said, "Tell me, I hope it's good news."

'Good news...it's probably impossible. '

Thomas muttered in his heart and said, "That's right, Mr. Minister, we have received news that Fanxing's aerospace department has made big moves recently."

"Our intelligence officers discovered that they were developing a special rocket..."

………………

Desert Space City.

This is the earliest and largest comprehensive missile and satellite launch center established by Fanxing. It undertakes the testing, launching and flight testing of various satellites and spacecraft, as well as command, measurement and safety control tasks, and processes the above measurement results.

There are also spacecraft landing rescue and escape rescue, as well as spacecraft return capsule recovery missions.

The launch training of astronauts is also here.

Desert Aerospace City has an inland and desert climate, flat terrain, sparsely populated, little rain throughout the year, long daytime, annual average temperature of 8.5°C, relative humidity of 35%-55%, and more than 320 days a year for space launches.

It can also make full use of the land and aerospace measurement and control network, which is thousands of kilometers away from the westernmost point to the easternmost point in the country. In addition, the base has been built for many years and has basically complete living facilities, including technical support, measurement and control communications, railway transportation, power generation and distribution and other supporting facilities. Perfect, the conditions are very suitable for the launch of satellites and manned spacecraft.

At the same time, the land here is sparsely populated, which is very suitable for experimental space launches.

Today, in the absence of manned space launch missions, the Desert Space City welcomes many tourists.

To be precise, it is a group of reporters, both domestic and foreign.

At this time, they were all outside the cordon, setting up their long guns and short cannon-like lenses and cameras aimed at the gate of the assembly plant.

In the factory building, Li Future and many engineers are doing the final inspection on the rocket to be tested today.

This rocket is not big in size, and it is put on a "log transport vehicle" as a whole, probably to make it different from missiles. Its launch vehicle and monomer are painted white, and there are space-specific ones. The blue stripes are used for embellishment, and the words "Long March-11 Solid Launch Vehicle" and the logo of "Starry Aerospace" are also written on it.

The Long March 11 rocket is not a new rocket, it successfully made its first flight seven or eight years ago.

It has a total length of 20.8 meters, a diameter of 2 meters, a weight of 58 tons, a take-off thrust of 120 tons, a 700-kilometer sun-synchronous orbit carrying capacity of 400 kg, and a low-orbit carrying capacity of up to 700 kg.

It adopts the international common satellite-rocket interface, which can meet the diverse launch requirements of different mission loads and different orbits.

The rocket system consists of a solid launch vehicle and a launch support system. The first stage uses the solid rocket motor with the largest scale and thrust in the stars, which can tow the development of large solid motor and solid booster technology for the launch vehicle.

It has the characteristics of overall storage, simple operation, low launch cost, and short launch period. The biggest advantage is "fast, convenient, and flexible." emergencies and other emergency launch requirements.

It can be done within 24 hours from the arrival of the satellite to the launch of the rocket.

If it has been installed on the launch vehicle, it can be launched within an hour, and it also has the ability to launch all-weather and without support.

The so-called unsupported launch means that there is no need for a special rocket launch site, no service tower, no umbilical tower, no diversion tank, no launch pad, as long as there is a place where a "log transport vehicle" can be parked. Flat land is fine.

It does not have the tall launch towers of traditional launch vehicles, and the entire Long March 11 is accommodated in a vertical launch tube.

When the rocket is launched, the high-pressure gas is ejected out of the barrel, and after reaching a certain height, the first-stage rocket engine is ignited to start climbing, so the rocket seems to have a pause during launch.

This launch method is called vertical cold launch, and the famous S-300 low-altitude missile system also uses the same launch method.

The design of the Long March 11 highlights the word "quick", which requires mobile launch capabilities, requires that the installation and commissioning of the satellite rocket be completed within 24 hours after receiving the launch mission, and that launch preparations are completed within one hour after arriving at the launch point.

Therefore, like the intercontinental missile, it is packaged in the storage tank after production, and only the head fairing is exposed, which is convenient for long-distance transportation and requires no maintenance.

This storage tube is also a launch tube. In order to simplify the entire launch tube system, to avoid direct ignition and thermal launch, it is necessary to arrange complex gas discharge channels at the launch site, and to prevent high temperature from burning out the launch device.

Because the launch tube is to be reused.

And in this way, it can also be launched at sea.

In recent years, many countries located in the equatorial region have increasingly strong demand for launching near-equatorial, low-inclination satellites.

The closer to the equator to launch this type of satellite, the smaller the loss of carrying capacity and the lower the launch cost.

Therefore, launching rockets from the sea close to the equator has become a launch mode that many aerospace powers are competing to develop.

In response to the needs of international commercial users, Fanxing launched a low-inclination launch service at sea three years ago. This launch service "will be a more cost-effective launch method" for low-inclination satellites.

From its research and development to the present, all its launch missions have been successful.

But let’s not talk about whether the launch is successful today, or even if the launch fails, it can’t be regarded as the Long March 11, because although it is wearing the clothes of the Long March 11, it is not the Long March 11.

It doesn't have an official name yet, but if it had to be said, it would probably be the "Solid Metal-Hydrogen Mixed Fuel Test Arrow".

First of all, its length does not reach 20.8 meters, but only 12.5 meters. With a diameter of 2 meters, it looks a bit short and fat.

And its length has been shortened, and the corresponding launch tube has also been shortened, so that the fairing part for it to carry the satellite is still exposed outside the launch tube.

The volume has shrunk, and the weight has also shrunk naturally, from 58 tons to 30 tons.

30 tons, excluding the weight of the rocket casing and cargo, the weight of the fuel alone is more than 20 tons, which is filled with solid metal-hydrogen mixed fuel.

For the current star productivity, it is an expensive batch!
Fortunately, the effect of metal hydrogen is still powerful, even if it is mixed.

The fuel loaded is less, but its capacity has not decreased, and it has even increased, from 700 kg in low earth orbit to 1500 kg!

This is a very heaven-defying existence, and the low-Earth orbit carrying factor has directly reached 5%.

That is, the take-off mass of the rocket multiplied by the load factor, which is probably the weight of its cargo.

Generally speaking, liquid fuel rockets have a relatively high load factor, the highest in low-Earth orbit can reach more than 4%, and the usual one is 2% to 3%.

For solid-fuel rockets, the low-Earth orbit load factor is generally around 1%.

This has to be graded, that is, after flying for a while, throw away the dead weight that has exhausted the fuel, so that the rocket can keep a lighter mass.

But this test arrow is different. It has no classification, only the bottom nozzle. The plan is to enter the orbit in a single stage, and directly send the carried equipment to the orbit.

In fact, single-stage orbiting is a "very stupid" idea, because it will always fly with dead weight, so the load factor will be very low, so low that it can only send its own empty shell to space orbit, and cannot carry any items .

He couldn't even send it to himself.

Of course, some people are justified in their obsession with it, because its mechanism is very "simple".

There are many reasons for the failure of rocket launches, among which there are situations where multi-stage rockets cannot be separated, collide after separation, or fail to ignite after separation.

This would not have happened if it had been a single-stage entry into orbit.

Just one level, no separation required.

There is only a nozzle for take-off, take off if it can be ignited, and wait for it if it can’t be ignited. You don’t need to think about the problem of ignition failure when you are in the air.

After calculation, people found that its disadvantages far outweigh its advantages.

There are too few things that can be carried by a single machine into orbit, and the load factor is very close to 0, and it may not even be able to be transported, that is a negative number!
The danger of multi-stage separation has become less and less with the continuous development of technology.

But with the appearance of metallic hydrogen, this situation has changed again.

After recalculation, the scientists found that its carrying factor has increased, even the carrying factor of a single-stage orbit is quite impressive.

For freight, it is definitely not cost-effective to enter orbit on a single stage.

But if it is manned, the attraction of single-stage orbiting is even greater.

A simple structure means safer, which is too important for manned spaceflight, even if fewer things are transported.

Even if this test is successful, Fanxing Aerospace Department and Li Future will try the legendary manned spaceflight artifact.

Aeroplane!

The aerospace plane is a very powerful aircraft. It can take off horizontally like an ordinary aircraft, fly in the atmosphere at a hypersonic speed of 1.6 to 3 kilometers per hour, and fly at a speed of 30 to 100 kilometers at an altitude of 12 to 25 kilometers. Double the speed of sound, and can be directly accelerated into the earth's orbit, becoming a space vehicle.

After returning to the atmosphere, it lands at the airport like an airplane and becomes a means of transportation between the sky and the earth freely.
