The sample arrow of Xinyuan-2 was transported to Qiongzhou, and such a huge scene naturally did not hide from people, like the world announcing the birth of another heavy rocket in advance.

Xinyuan-2 represents several histories:

Asia's first heavy rocket with a take-off weight of more than 1,000 tons;

the first rocket in Asia (Lucia now has no production capacity for heavy rockets);

Asia's first rocket with a liquid oxygen methane engine;

The rocket with the largest diameter of the core stage in Asia (the core stage of the proton rocket is not counted);

The world's first practical high-thrust liquid oxygen methane engine M220;

the most powerful rocket of the world's private space companies;

the world's heaviest recoverable launch vehicle;

The world's first recyclable rocket with grille rudder support recovery;

……

In particular, the scene of the majestic Il-76 with the first-class airlift of the Xinyuan-2 sample arrow, which is larger than the fuselage to the naked eye, has caused countless aviation enthusiasts to go crazy.

The only comparable mission is the Alliance's An-225 super-heavy transport aircraft transporting the Buran space shuttle.

Compared with the Il-76, the An-225 is an out-and-out big guy, with a maximum take-off mass of 640 tons, the back of the aircraft can carry more than 200 tons, and the cabin can withstand more than 200 tons, making it the largest transport aircraft in the world from the moment it was born.

Hey, do you want to buy the An-225 back now?

Lin Ju kept this incident in mind and was ready to contact Antonov when he was going to contact him.

Fingerprint unlocks its own chrysanthemum mate7, which is a premium version that was only released in September last year, supports dual SIM 4G, and is equipped with a Hisilicon Kirin 925 processor.

A little nostalgic for the era of full screen, Lin Ju opened the blog, and sure enough, it was an unsightly background message.

The number of followers on his personal account has exceeded one million, but Lin Ju usually forwards the news of Xinyuan's official Weibo, and generally does not send messages.

The Xinyuan No. 2 sample arrow was shipped, and there were countless people @ him all of a sudden.

Lin Ju shook his head and directly took a picture of part of the rocket body of the first rocket of Xinyuan-2 that was really ready to be launched in the assembly plant, with the text "Xinyuan-2, ready to attack!" , turn off the phone after sending it out.

It is now May 8, and the Xinyuan-2 sample rocket has already arrived at the Qiongzhou launch site, and has just completed the rocket body test and simulation assembly procedures.

The first airspace site was a bit confusing, and a lot of time was wasted specifying procedures, but fortunately, there was no problem with the rocket, and the final assembly of the plant at the Qiongzhou launch site was also fast and stable.

Therefore, the Xinyuan-2 Yao-1 rocket will be changed to air transportation, and there will be no longer waiting for the cheating inland river to be transferred to sea transportation.

The manufacturing base of the Space Bureau is Jingu, and it will be loaded all the way to Qiongzhou when it comes out; Xinyuan is inland, from the Yangtze River tributary to the river boat to the sea to change to the sea, this can reach Qiongzhou, it is simply troublesome.

The level of the Air Force Il-76 crew is very good, as long as there are no complicated weather conditions, the risk is practically similar to that of sea transport.

Not far from him, Anderov was supervising the loading of a large special-shaped part.

The second stage of the Xinyuan-2 rocket has a diameter of 6 meters, and the tail of the H1 space shuttle is not a standard circle, so it needs a pneumatic connector for the transition.

Anderov took advantage of this part of the space, designing it as an escape.

It is normally the connector between the shuttle and the rocket, but if there is a problem with the rocket, the explosion bolt at the bottom will control it and the shuttle to separate from the rocket, and then the solid rocket engine starts in less than 0.1 seconds, pushing the shuttle away from the rocket at the fastest speed and flying diagonally to the sky.

At this time, the escape vehicle is detached, and the astronauts who react can manually control the shuttle by ground remote control or computer adjustment if there is an accident, and then find an airfield for landing.

After all, Aramco's space shuttle accident is still fresh in our minds, and the last space shuttle was only mothballed in 2010, so it is necessary to prevent it.

When Anderov saw that the escape device was installed, he ran over to Lin Ju's side:

"Boss, the design of the Xinyuan No. 5 family and the Xinyuan No. 6 has been completed, do you want to start making sample arrows?"

A long time ago, system engineers proposed to enrich the rocket lineage of Xinyuan and develop rockets of various classes, but in the end they were all delayed, and now the plan is finally given.

Xinyuan No. 5 Family:

The basic type of Xinyuan 5 adopts a 3.5-meter diameter rocket body, a three-stage rocket design, and the core stage is equipped with a K380 liquid oxygen kerosene engine, with a take-off thrust of 384 tons, a maximum take-off mass of 316 tons, a low-earth orbit carrying capacity of 7.9 tons, and a first-stage recoverable;

Xinyuan No. 5 A: On the basis of the foundation, two 2.5-meter diameter boosters are bundled, each with a K120 engine, which is the core first-class version of Xinyuan No. 1, with a maximum take-off thrust of 628 tons, a maximum take-off mass of 508 tons, and a LEO capacity of 14 tons, and the booster and core stage are recyclable;

Xinyuan 5B: bundled with four 2.5-meter boosters, with a take-off thrust of 880 tons, a maximum take-off mass of 770 tons, and a LEO capacity of 21 tons.

Xinyuan-6: a fourth-stage solid rocket with a diameter of 3.5 meters, the first stage is equipped with an S85 solid rocket engine, with a take-off thrust of 85 tons, a take-off mass of 50 tons, and a low-earth orbit capacity of 500 kg.

Among them, the Xinyuan-5 family is a multi-purpose recyclable modular general-purpose rocket covering medium and large-scale launch missions, and the Xinyuan-6 is a solid launch vehicle that can be launched quickly and maneuverably for emergency launch requests.

According to the original plan, H1 can actually be launched by the smaller Xinyuan-5B, which just happens not to waste thrust, but for quick consideration, the K380 of the core stage and the full-flow kerosene engine are a bit troublesome, so the heavy-duty rocket Xinyuan-2 that is directly on the methane machine was chosen.

Of course, it is also possible that the system engineer is overconfident and wants a big toy, and Lin Ju may not be able to push it half~

Although Xinyuan-6 is an out-and-out disposable small rocket, it is easy to manufacture, short in cycle, and very satisfying when it is used urgently, and it only takes 4 hours from pulling out to launching.

Of course, the main purpose is to verify the S80 parent engine, the S700 produced by the system, a solid rocket engine with a single stage of 700 tons of thrust with a diameter of 5 meters!

Solid rocket engines are completely different from traditional liquid rockets, its fuel is cylindrical solid, and combustion is from the center to the outer ring.

This leads to the fact that it has the ability to overlap solid rockets and increase the area of simultaneous combustion in tandem, and the thrust will be multiplied.

If you connect a few knots in series, the thrust will be multiplied by a few.

Aramco's solid rocket booster for launching the space shuttle is made up of four solid rockets of 300 tons in a single stage, with a total thrust of 1,200 tons.

If the S700 is also connected in series with 4 knots, then the overall rocket thrust is an extremely terrifying 2800 tons.

The total thrust of the 27 engines in the first stage of the core of the Xinyuan-4 giant rocket is only 6,500 tons, but the total thrust of the four such boosters bundled is 11,200 tons!

Of course, that's foolish, the thrust of the solid rocket engine is almost unadjustable, and there is no bundle structure that can withstand the sudden burst of 10,000 tons of thrust.

There are three sections in a string, and there are 2,100 tons of thrust boosters, and it is completely enough to bundle two, which is basically the limit of human current materials science.

So solid rockets are a shortcut to high thrust, the only drawback is that it is too expensive, although it can be recycled and reloaded, but it is precisely the fuel that is expensive.

Lin Ju should be fully approved, but even so, he has to wait until the B-level base is put into practical use before he has the energy, so he should be regarded as a technical reserve......
