Class B base.

The B4043 landed lightly on the runway, and then the nose folded up to reveal the stacked wooden boxes of various sizes, which were then carefully lifted down one by one by the forklifts that had been waiting here early and placed on the transfer carts in the factory.

Seryov was standing next to the plane wearing a shirt and behind his back, communicating with Zeng Hongwei and Yang Wei, deputy chief engineers of the Tengyun Engineering of the Third Academy.

These different cargo boxes were loaded onto the plane from different places such as Mukden, Chang'an, Guizhou Province, and Modu, and they were accompanied by technicians sent by the manufacturer, who flew here together in the wide crew compartment on the back of the transport plane.

The larger cargo box contains the tail, rudder surface, landing gear hydraulics, etc., and the smaller cargo box is the fuselage electronics and sensors, except for the main engine body and engine, the rest of the components are almost all here.

Of course, the Rongcheng Institute also undertook part of the parts development task, but they didn't need to be so troublesome to transport them directly by car, and Yang Wei came to help in person.

The technical support personnel who flew in from all over the country were forming a team under the plane, once again emphasizing the secrecy discipline of the base, but fortunately, if they can come here, they can already be regarded as "reliable" and do not need to be overly vigilant.

"All the parts of Tengyun's prototype are all ready, and we spend half a month for final assembly, half a month to a month for ground testing, and then catch up with the first flight on the National Day."

Zeng Hongwei had no objection to Seryov's schedule, not only was the latter the chief engineer, but he also really knew how fast the Tengyun project was progressing.

After sending the model to Chang'an to blow the wind tunnel, in May and June, the base built two full-scale static test prototypes, and then scrapped them all in July.

The trial production task of the prototype parts was issued after the TP25 engine prototype passed the test in April, and after waiting for four months, all the qualified parts were finally obtained.

The TP-25 has also completed the mass production of the first batch of 12 units, one of which has performed extremely well in the desert base for the Wuzhan 20, and he is also confident that there will be no major failures.

But Yang Wei was a little hesitant:

"Tengyun Engineering is too advanced, this is SSTO, do you want us to build another scaled-down prototype?"

Zeng Hongwei: "Don't worry about technical problems, in fact, the sooner Tengyun enters service, the better, and after having him, our manned space mission will be much cheaper, this is a ...... Non-military projects. ”

Yang Wei: "But didn't the military say that it would find a way to make the Tengyun project a first-class use and send a 30-ton small space shuttle to it?" ”

Zeng Hongwei: "That's the next project." ”

Although the current design of the Tengyun project is a single-stage orbit, the space agency and the military have subsequently put forward a suggestion for improvement: make minor changes to its body, continue to carry a small rocket or a small space shuttle on its back, and send a larger load into space cheaply like the original Tengyun project first.

This is very similar to the launch method of the "Lightning", but the advantage is that the load factor is higher and there is no need to abandon the fuel tank, which can put a 30-ton space shuttle or a 20-ton satellite into orbit, which is relatively more convenient and discreet.

The load of 2.8 tons in a single stage into orbit is a bit chicken, and the practicality is not as good as that of manned.

Seeing the two chatting about the follow-up evolution of the Tengyun Project, Seryov suddenly interjected:

"Do you know about МГ-19 (MR-19)?"

The two did not understand the pronunciation of the Cyrillic alphabet, and Seryov explained:

"In 1974, when the alliance planned to develop aerospace vehicles, there were several routes of American space shuttles and aerospace aircraft, Tupolev proposed the Tu-2000 aerospace aircraft, and Miyasyshev's plan was the MR-19 nuclear-powered aerospace aircraft, all of which were SSTO single-stage orbital.

If the combustion chamber part of the turbine and ramjet engine is replaced with nuclear power, and liquid hydrogen is used as fuel, 500 tons of take-off mass can send 40 tons of payload, and if we resurrect it, the take-off mass can be reduced to 350-400 tons. ”

“……”

“……”

"Don't worry about nuclear contamination, its principle is different from that of A100, hydrogen atoms will not be radioactive when ejected, and because of nuclear power, it can repeatedly enter the atmosphere and re-enter orbit, and the speed can reach more than Mach 15, which is an ideal military aircraft."

Yang Wei subconsciously thought that this sounded too difficult, but when he thought about it...... Xinyuan's nuclear propulsion technology is quite strong, it seems that it is really possible?

As soon as he thought about the nuclear reactor scurrying around in the atmosphere at Mach 15, he quickly shook his head.

Zeng Hongwei also opened his eyes wide, even if the nuclear aircraft flew in space, don't bring it to the earth, this ghost thing is stirring the nerves of the air defense forces of various countries every second in the sky.

"Mr. Xie, it's enough to have the new No. 10 project (Xuehu project codename) to go out and be scary, and the nuclear power is soaring...... How expensive liquid hydrogen is, it's not cost-effective, don't report it. ”

……

Moon.

"Deng, Lee, can this console be placed here?"

Ryana held a half-human-tall comprehensive science bench and tool cabinet, hesitating to know where to put it.

"Just put it next to the support leg, and wait for me to put the rover down first."

Li Wei is laying down the second lunar rover to prepare for the second out-of-cabin exploration mission.

As for what Deng Lei is doing? Deng Lei is looking for a place to shoot a publicity conference.

The first lunar rover was driven to a small hill by him to find a suitable angle, and then set up broadcasting equipment and forwarded it to Xin'an for propaganda purposes, and then appeared on camera to take a photo, and then came to clean it up an hour later.

The mission schedule of Tianmu 2 is still very tight, and it has to complete three out-of-cabin missions in 48 hours, the first time is basically to advertise and move materials to prepare, and the second and third are to explore.

But this time it's okay.,And then the Tianmu series of tasks are basically the support of United Mining.,Every step you take must consider the economy.,The materials consumed can basically be counted as the property of United Mining.,Those are bought by the company.,Time is money.。

Li Wei put down the "Chitu 02" lunar rover neatly, the new spacesuit and the gravity environment made him quite flexible, and after driving the lunar rover a little distance, he and Reina placed the equipment together.

Originally, there was an explorer robot near the mine, but unfortunately the robot lost contact after a moonlit night a week before the mission was launched, either "dead", or it could have been stuck in a pit and could not get out and the signal was blocked.

The mechanics of the Explorer are not stellar, and the cost of flexibility is a rapid loss of life, and the loss of one is not surprising.

After analyzing the Dawning 3 mission, Li Wei felt that the assistance provided by the robot was quite large, and if he had known that one of the two lunar rovers should be replaced by a robot, the weight would be about the same anyway.

When the three astronauts had left the capsule for five hours when they were almost done with their work, Li Wei took out a hand-held camera from his toolkit and pressed the shutter on the earth, which showed only a touch of blue.
