Chapter 843 A lifetime of running errands

PS: 8000 words, no more today.

The third engine is also 60% complete. There is still more than a month left before the second moon landing in 2007, which is enough time.

"I've had enough of staying in this miserable place." He Gui looked at the surrounding environment and realized that he had spent most of his time here in modern times.

Of course, a lot of results were achieved, and He Gui was still very satisfied, at least he had taken care of both sides.

"Let's get started." Put on work clothes and gloves. This workshop is a constant-temperature workshop, not as precise as a laboratory, but it is also a dust-free workshop.

Wear gloves to prevent sweat stains or other things from adhering to these parts, which may cause some trouble.

After the parts are installed one by one, check them again, and then continue to install other parts. The installation and inspection records need to be recorded in your own installation manual.

This is a workflow, although it is older and more primitive, but it is also one of the most effective methods.

Scientists once conducted experiments and found that the longest way to preserve writing is on rocks. Yes, it is carving words on rocks. Some ancient cave paintings may be millions of years old, but there is no other way in the world.

Materials can preserve text for that long.

I spent the modern New Year in a busy schedule. I originally planned to take my family to Xisha, but in the end my family all went, and He Gui didn't go because He Gui couldn't leave. Something might happen there at any time in 2007.

He Gui himself didn't feel lonely at all. After all, he could still go to the project department there in 2007, where the project department was full of people.

Nicole's parents also came, but they settled in Hainan. He Gui also provided a house there and there were many villas there. Nicole's parents like the sea very much. This may be related to the fact that Serbia does not have an outlet to the sea.

When the family came back from vacation, He Gui's three engines were also assembled.

There is still a lot of work left. Fortunately, XAC has brought over many of the remaining parts, including computers, chips, pipelines, connectors, beams, landing gear, seats, and various instruments.

The rest of the fuselage skin is special, so why bother doing it yourself?

He Gui asked Gao Zhong to call XAC and ask them to take away an engine for testing, while He Gui and Gao Zhong packaged the engine.

The entire engine is six meters long, almost 1.5 meters in diameter, and weighs 3.4 tons. It is packaged in a wooden box with some padding inside to ensure the stability of the engine.

The people from Xifei came very quickly, this time it was the chief engineer.

"Teacher He." The chief engineer took a plane to the nearest military airport and then took a car.

"There is an engine inside. It has been tested. You can go back and test it again. Some optimizations have been made. There have been some breakthroughs in fuel economy and a slight increase in thrust." He Gui said.

The NK321 engine cannot even be manufactured by AmeriCorps. It is a monster level. Moreover, Lao Maozi’s NK321 engine has a speed limit when taking off because the speed is too fast and the fuel is insufficient.

I saw the yellow smoke emitted by the 160 when it took off. It was nitric acid. It was incomplete combustion and formed nitric acid with water molecules in the air.

"Thank you, Teacher He. Thank you. It's not convenient for our boss to come here this time. It seems that the stealth bomber above has some clues."

"Really? This is a good thing." He Gui was also surprised, but it was not convenient for He Gui to ask about the specific situation.

"Teacher He, I'm going to leave first. I'll leave everything to you. We're waiting for your good news, and we've also brought you some souvenirs."

"Thank you, have a nice trip." He Gui nodded, then installed the installed engine on the flatbed truck, and then covered the outside of the truck with a raincloth or the like.

Xifei's local specialties include many Chinese medicinal materials. Licorice, skullcap, etc. are produced around Chang'an, as well as mutton and the like.

It was really a local specialty. The chief engineer of XAC went to the underground parking garage of the military airport with the car in great fear. The chief engineer of XAC arrived in XAC’s own transport plane, and it was naturally the same plane when he returned.

The flight route of this plane will not be disclosed to the public and is a secret.

XAC's chief engineer transported the goods to XAC, and a big boss quickly came to the scene to unpack them.

"This is?"

"It's the engine used by the Gyrfalcon, but Teacher He has made some improvements. The details will depend on the test data." XAC Chief Engineer said.

"Tsk, tsk, a stealth aircraft equipped with such a big engine, I'm really looking forward to it."

"Yes, boss, what kind of stealth bomber is it manufacturing?"

"I don't know. The level of confidentiality is very high and it is not convenient for us to inquire."

"Yes, yes." The chief engineer of XAC knows that people who engage in confidential research should do more and talk less. Maybe an unintentional sentence will be misunderstood.

"Is this ignited?" Da Toutou looked at the burning part behind the engine.

"Teacher He started it in one hour and there is test data."

"Teacher He is awesome. He made this thing by himself. Even though it has been so many years since he first came into contact with it, it is still incredible when he thinks about it."

"Yeah, maybe only Korolev when he was a bear can compare."

"Absolutely. Teacher He has learned a lot from it."

What followed was a series of preparation work, and the engine was sent to a special testing site. By the time everything was ready, it was already the afternoon of the next day, and the chief engineer was too excited to rest.

"Attention all units, code number 68, first ignition test, three seconds."

"start up."

The rocket engine test preparation work is relatively complicated. Unlike He Gui's side, one person does all the work here. XAC's side is much more formal.

Fuel preparation, oil preparation, power preparation, fire protection, etc. require the cooperation of various units, as well as inspection of the engine to see if it will cause problems during transportation, so it is relatively slow.

Along with the sound of the starter, the engine ignites successfully and makes a huge roar. The pressure fan at the air inlet makes a huge roar, which is compressing the air into the combustion chamber.

Although it has been running for an hour at Hegui, when it comes to Xifei, it has its own process.

The ignition was successful and the chief engineer breathed a sigh of relief.

Two days later, the chief engineer took the data files and made a report.

"Boss, the data is out."

"How about it?"

"The fuel utilization rate has increased by 15%. After detailed analysis, we found that Mr. He mainly made improvements in the fuel pressure and fuel nozzles."

"That is to say, the same fuel can increase the range and increase the thrust."

"In addition, improvements have been made to the three-stage turbine, and we need to continue to study the details. The thrust is three tons more than what we are currently equipped with."

"Oh, we seem to be over 26 tons now?"

"Yes, this engine is now close to the 30-ton figure. This is also the engine with the highest thrust in the world."

"well."

"It's just that the quality is 40 kilograms more than the original one."

"Get all the data as soon as possible and make it complete."

"yes."

XAC continued testing, and He Gui began to make aircraft skins. The gaps between the aircraft skins of stealth fighters were a problem.

It is said that B2 uses an elastic material. In addition, the stealth coating of B2 is made of a material. After absorbing electromagnetic waves, this material will be converted into heat and be reduced by the constant temperature system inside the aircraft.

This material is similar to a fiber structure, so B2 needs to be maintained in a constant-temperature hangar.

Because after flying once, the aircraft needs to be maintained. The high-speed friction of the air causes damage to the fiber material and needs to be repaired.

The fuselage skin on He Gui's side uses a structure similar to bird feathers, which is the embedded type. After all, as long as the radar around the front of the stealth bomber cannot be illuminated, the radar at the back can definitely be illuminated. After all,

There's no way to hide the engine nozzle on the tail.

The embedded technology of the entire skin is irregular. Of course, it cannot be seen from the outside. There is a material between the gap between the front piece of aircraft skin and the back piece of aircraft skin. This material can internally control expansion and contraction. This material is

A one-way fiber tube technology, any heat, electromagnetic waves, etc. absorbed will be transmitted in one direction.

Designers in 2007 originally planned to use this type of fiber tube directly between the aircraft skins, but the aircraft skins were stressed unevenly and were not as strong as embedded ones.

That is to say, if it is simpler, the stronger the force, the longer the maintenance time will be.

The unidirectional fiber tube technology can also balance the temperature on the aircraft so that the surface temperature of the aircraft is consistent with the temperature of the surrounding space.

Of course, this fiber tube is very thin and can only be seen with the naked eye if you get close, but cannot be seen from a distance.

Stealth materials are also used for fighter jets, and they are very cost-effective.

The air inlet of a stealth bomber is like a periscope. There is a stealth coating on the inside and outside of the air inlet so that the engine fan will not be exposed to radar radiation.

This is also why the air inlet of B2 is on the back, because the engine air intake fan cannot be exposed. The weird shape of the air inlet of B2 is actually to compress more air into the engine.

He Gui put the girder prepared by Xifei in place, and then began to plan. This girder was irregular. It looked like it was tilted up at the back, and lower at the front because there were two engines hanging at the back and there were bombs at the front.

Warehouse and part of the cab, etc.

For this beam, the one-piece forging technology is used, and its strength is many times higher than that of welding.

There are still a lot of troubles in welding, such as inspection, polishing, etc.

After the girder is prepared, it’s time to install the various internal equipment, pipelines, etc...

——————————————2007————————————

Three days before the second manned moon landing, He Guicai showed up.

He Gui took the person in charge to the vertical assembly workshop. The vertical assembly workshop is a huge three-dimensional enclosed space with a height of 120 meters and a side length of 30 meters. He Gui wore work clothes and walked out of the elevator at the 65-meter position.
