I ask you to build tractors, but you build rockets?

The prototype rocket of Xinyuan-2 was shipped to Qiongzhou. Such a huge scene was naturally not hidden from anyone, as it announced the birth of another heavy-lift rocket to the world in advance.

Xinyuan 2 represents multiple histories:

Asia's first heavy-lift rocket with a take-off weight exceeding 1,000 tons;

Asia’s No. 1 rocket (Lucia currently has no heavy-lift rocket production capacity);

Asia’s first rocket using liquid oxygen methane engine;

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

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

The world’s most powerful rocket from a private space company;

The world’s heaviest reusable launch vehicle;

The world's first recyclable rocket that uses a grid rudder to support recovery;

…

In particular, the scene of the majestic IL-76 carrying a first-level airlift of the Xinyuan-2 prototype rocket, which looked larger than the fuselage to the naked eye, made countless aviation enthusiasts go crazy.

Only the Alliance's An-225 super-heavy transport aircraft transporting the Buran space shuttle can be compared with this spectacular sight.

Compared to 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 fuselage can carry more than 200 tons, and the cabin can withstand another 200 tons. It has been the largest transport aircraft in the world from the moment it was born. .

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

Lin Ju kept this matter in mind and planned to contact Antonov when he could.

Use your fingerprint to unlock your own Daisy Mate7. This is the Honor Edition released in September last year. It supports dual-SIM 4G and is equipped with a HiSilicon Kirin 925 processor.

After a little nostalgia for the full-screen era, Lin Ju opened his blog, and sure enough, he couldn't see the background news again.

The number of followers on his personal account has exceeded one million, but Lin Ju usually forwards news from Xinyuan's official WeChat account and generally does not post any news.

The Xinyuan No. 2 sample arrow was launched, and suddenly countless people @him.

Lin Ju shook his head and directly took a picture of part of the Xinyuan-2 first rocket that was actually preparing to be launched in the assembly plant, with the text "Xinyuan-2, prepare to attack!" After sending it, he turned off his mobile phone.

It is now May 8. The Xinyuan-2 prototype rocket has already arrived at the Qiongzhou launch site and has just completed the rocket body test and simulated final assembly process.

The first airlift was a bit confusing, and a lot of time was wasted on specifying the procedures. However, fortunately, there were no problems with the rocket, and the final assembly at the Qiongzhou launch site was fast and steady.

Therefore, the Xinyuan-2 Yaoyi rocket will be transported by air instead of waiting for the cheating inland waterway to be transported by sea.

The manufacturing base of the space agency is Jingu, and you have to ship it all the way to Qiongzhou. Xinyuan is inland, and you have to load it on a river ship from a tributary of the Yangtze River to the seaport and exchange it for a sea ship. Only then can you reach Qiongzhou, which is really troublesome.

The Air Force's Il-76 crews are very capable. As long as there are no complicated weather conditions, the risk is actually about the same as shipping.

Not far away from him, Androv was supervising the loading of a large special-shaped component.

The secondary diameter of the Xinyuan-2 rocket is 6 meters, and the tail of the H1 space shuttle is not a standard round shape, so pneumatic connectors are needed for transition.

Androv took advantage of this space and designed it as an escape device.

It is a connecting piece between the space shuttle and the rocket under normal conditions, but if there is a problem with the rocket, the explosive bolt at the bottom will control it and separate the space shuttle from the rocket, and then the solid rocket motor starts in less than 0.1 seconds, with the fastest speed The speed pushed the space shuttle away from the rocket and flew diagonally high into the sky.

At this time, the escape vehicle breaks away, and the astronauts who react can manually adjust the space shuttle manually. If an accident occurs, they can also use ground remote control or computer self-adjustment to balance the space shuttle, and then find an airport for landing.

After all, Aramco’s space shuttle accident is still fresh in our minds. The last space shuttle was only mothballed in 2010. It is necessary to take precautions.

When Androv saw that the escape device was installed, he ran over to Lin Ju:

"Boss, the design of Xinyuan 5 family and Xinyuan 6 has been completed. Do you want to start making sample arrows?"

A long time ago, system engineers proposed to enrich Xinyuan's rocket pedigree and develop rockets of all levels, but in the end they delayed it, and now the plan has finally been given.

Xinyuan No. 5 family:

The basic model of Xinyuan-5 adopts a 3.5-meter-diameter rocket body and a three-stage rocket design. 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, and a low-Earth orbit carrying capacity of 7.9 tons. grade recyclable;

Xinyuan-5A: On a basic basis, it is bundled with two 2.5-meter-diameter boosters, each with a K120 engine, which is the core-level version of Xinyuan-1. It has a maximum take-off thrust of 628 tons and a maximum take-off mass of 508 tons. , LEO capacity is 14 tons, 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 transport capacity of 21 tons.

Xinyuan-6: A four-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 transport capacity of 500 kilograms.

Among them, the Xinyuan-5 family is a multi-purpose recyclable modular general-purpose rocket covering medium and large launch missions, while the Xinyuan-6 family 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 is just right without wasting thrust. However, for quick consideration, the core-stage K380 and full-flow kerosene engine are a bit troublesome, so I chose to directly use the methane engine. The heavy-lift rocket Xinyuan-2.

Of course, it is also possible that the system engineer was overconfident and wanted a big toy, and Lin Ju might have given it half a push~

Although Xinyuan-6 is an out-and-out disposable small rocket, its advantages are that it is simple to manufacture and has a short cycle. It is very satisfactory when it is needed urgently. It only takes 4 hours from pulling it out to launching.

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

The solid rocket motor is completely different from the traditional liquid rocket. Its fuel is a cylindrical solid, and the combustion is from the center to the outer ring.

This leads to its characteristic that the solid rockets can be overlapped to increase the simultaneous burning area during series connection, and the thrust will be doubled.

The thrust is multiplied by how many sections are connected in series.

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

If the S700 also has 4 sections in series, then the overall rocket thrust will be an extremely terrifying 2,800 tons.

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

Of course, that is deceptive. The thrust of the solid rocket motor is almost unadjustable, and there is no binding structure that can withstand a sudden burst of 10,000 tons of thrust.

A three-section booster with a thrust of 2,100 tons is enough to be bundled with two. This is basically the limit of human materials science at present.

Therefore, solid rockets are a shortcut to high thrust. The only disadvantage is that they are too expensive. Although they can be recycled and reloaded, the most expensive thing is the fuel.

Lin Juyi responded in full, but even so, he had to wait until the B-level base was put into practical use before he could focus on it. Let's just regard it as a technical reserve...
