Chapter 101 Can I go to the air show?

After confirming that there were no problems with the improved design plan, Yan Zhongcheng signed his name on the document confirming the production of two improved turbojet 14 engine prototypes.

As mentioned earlier, due to the very complex structure of the multi-stage axial flow compressor, even Chang Haonan has no way to conduct accurate calculations and simulations of a jet engine with a complete structure and without model simplification.

Therefore, the specific performance of this new turbojet 14, which has been reborn from nirvana, still needs to go through a series of tests to know.

The two prototypes, code-named 010001 and 010002, were produced respectively for high-altitude and aerial platform testing.

Generally speaking, the time required for this process can range from a few months to a few years. Fortunately, the turbojet 14 that has undergone major changes is still a turbojet 14 after all. Although the test items are indispensable, the test process will definitely be faster than A truly new engine is faster.

"If you count the time..."

Chang Haonan was stunned for a moment, and then realized that he didn't even know what day it was today.

Habits are indeed a terrible thing.

Because for the past ten years he had just grabbed his phone to look at the date, so even though he had been reborn for several months, he still often forgot the specific date.

Especially recently, he often worked overtime in a windowless computer room, which made him almost lose the concept of day and night.

Thinking of this, Chang Haonan turned his head and prepared to take a look at the calendar hanging behind him.

At this time, Yao Mengna was standing behind him, and she happened to be casting her gaze in this direction.

So the two looked at each other.

The other person's height was almost the same as his, completely blocking his sight.

But before Chang Haonan could adjust his position, Yao Mengna lowered her head as if she knew what he wanted to do.

Today is December 9st.

Chang Haonan quickly ran through the basic processes of ground and air simulations in his mind, as well as how long each project is expected to take.

"If everything goes well, we should still be able to catch up..."

Because he was so focused on thinking, he didn't even notice that he whispered what he was thinking.

"What can catch up?"

Yang Fenghata, who was standing nearby, asked in a somewhat doubtful tone:

"If you are talking about the finalization node, there are still nearly two years. With your efficiency after joining the project, it should not be a problem, so don't worry."

After speaking, he patted Chang Haonan on the shoulder, indicating that he could relax.

The stereotype that Yang Fenghata refers to naturally refers to the design stereotype.

According to the "Conventional Weapons and Equipment Development Procedures" issued by the four ministries and commissions in 1995, the development of conventional weapons and equipment is divided into the demonstration stage, program demonstration, engineering development stage, design finalization stage and production finalization stage.

Chang Haonan and the others are now in the engineering development stage.

Under normal circumstances, after the design is finalized, small batch trial production can be arranged and equipped with troops.

As for the finalization of production, it can only be completed after problems are continuously discovered and solved during the process. It is difficult to give a specific time node.

Considering the production process, sometimes the replacement speed is very fast.

Therefore, in actual operation, the small batch production of many weapons and equipment models is not "small" at all, and there may even be situations where the products have completed the entire life cycle and are withdrawn from active service but have not yet completed production.

So in most cases, when a project reaches the design finalization stage, it can basically be considered complete.

Others around him also cast glances of affirmation and approval.

If the modification of the wing design only made him somewhat famous within the 601 Institute, then the design modification of the Turbojet 14 spread the name Chang Haonan to almost the entire project team of the rd Project. .

"Uh... no, there is really no big problem with the design." Chang Haonan shook his head and said that this was not what he was thinking about:

"I'm wondering, if the test results of the Turbojet 14 go well enough, will the J-8-3 be able to catch up with this year's air show?"

Yes, this is the main reason why Chang Haonan has been closely following the progress of the August 3rd Project from the beginning.

The Xiangzhou Air Show, also known as the China International Aerospace Expo, will become one of the top six air shows in the world in the future.

But when we first applied for this air show, the core starting point was that Xiangzhou City, with a population of just over 90, wanted to apply for the construction of a super-standard airport with a 4000-meter runway.

There has to be a reason.

As a result, Jinwan International Airport was successfully completed, but the air show that was used as the reason did not receive official approval until 1995.

As a result, domestic aviation units were almost unprepared for this. In the end, they only sent a J-7MG, the export version of the J-7E, for a flight demonstration, and a J-8IIM, which made its first flight at the beginning of the year, for a ground display.

But even so, Chang Haonan still clearly remembers the excitement and excitement when he and a group of classmates saw the J-8IIM in a magazine.

After all, this aircraft using Russian-made avionics can launch R27 air-to-air missiles like the Su-27.

Later, when I started working, I learned that a J-8IIM flight show was originally scheduled. However, the left engine of the exhibiting aircraft stopped mid-air during the transfer flight to Xiangzhou, and had to go to Jiangcheng for an emergency landing. In the end, another aircraft temporarily took over. , the flight show was naturally cancelled.

It was not until the second air show in 1998 that the J-8IIM and the J-H-1, known as FBC7, made up for this late performance.

Therefore, in the original timeline, the most dazzling stars of the first Xiangzhou Air Show were a Su-27 and a Su-30MK on static display.

But this time, things are different after all.

The overhauled J-8-3 and the turbojet 14 with more stable performance.

Although there is still no way to completely match the third-generation heavy fighter on the card, at least it will not be completely overshadowed by others.

"Air show?"

Everyone's first thought was that Chang Haonan got the time wrong because he worked continuously for a long time.

When it comes to air shows in this era, the first things that come to mind are the Paris Air Show and Moscow Air Show held in odd years, and the Farnborough Air Show and Singapore Air Show held in even years.

Among them, the Singapore Air Show is held in February of even-numbered years, so it is impossible to make a mistake. However, the Farnborough Air Show in the UK, held from the first to the second week of September every year, is closer in time.

"But the Farnborough Air Show was just held two days ago?"

Someone next to me whispered a reminder.

"It's not Farnborough, I'm talking about..."

"Is it Xiangzhou?"

It was Yang Fenghata who reacted first.

"Yes, Xiangzhou Air Show."

Chang Haonan nodded and continued:

"Our Project 83 is a 'competitive machine' that has been personally directed. If it can be unveiled at our country's first air show, it will definitely be very exciting."

Upon hearing these words, the eyes of everyone present instantly lit up.

Who doesn’t want the aircraft he or she develops to attract worldwide attention?

"If I remember correctly, the Xiangzhou Airshow should open in early November, which means there is still time left for us..."

"Less than two months."
