Chapter 163 Success! The Eagle has the F119 engine, so what if we have the WS-119? !

A quarter past three in the afternoon.

In this Gobi desert covered with yellow sand, the sun hanging high in the sky shines on the earth.

Huge buildings stand out here, creating a sharp contrast with the surrounding environment.

Whether it is located in an uninhabited area or in an area of ​​dozens of kilometers around it that is designated as a military restricted area, it all symbolizes its extraordinary status.

"This place is suitable for aviation research and development."

"The environment is just too bad, and it's too inconvenient to live here for a long time." Song Qinyi sighed again from the bottom of his heart.

The Gobi Desert's dry climate with a moderate temperature makes it the most suitable place for aviation research and development.

After all, modern fighter jets are no longer those antiques from the last century. They are made entirely of mechanical components and are not greatly affected by extreme weather.

Like today's fourth and fifth generation fighter jets, they are integrated with avionics, radar fire control and other precision components.

Once the temperature is too humid, it may cause high-precision damage. As for the corrosion caused by excessive salinity and high temperature, it may even cause the main control system inside the fighter to fail on the spot.

But the disadvantages are also obvious. The Gobi Desert in the northwestern province is too remote and the convenience of living is almost zero.

If we carry out R&D work here for a long period of several years, it may be a great test of the spirit of every R&D personnel.

Song Qinyi stared at the aircraft engine in the distance and muttered slowly: "I think it shouldn't take that long."

At this time, an engineer with a shiny forehead came over with a stack of drawings in his hand.

"Engineer Song, all tests have been completed. The engine 'run-in' test can begin."

The aircraft engine 'run-in' test is the stage of conducting a complete test on an entire aircraft engine.

If routine tests are divided into a series of assessments, the successful first flight is the 'college entrance examination', and the 'test drive' test is the final monthly examination.

Generally speaking, once the "test run" is successful, the next stage will be to equip it on a fighter jet for the final maiden flight.

"I understand." Song Qinyi nodded seriously.

For Daxia, which has already achieved the successful maiden flight of the J-20, whether this engine can be successfully "tested" is of great significance.

If successful, according to the original plans, it will be equipped on future fifth-generation fighters such as the J-35 and J-31, and will also be transferred to various derivative models such as the J-10 and J-15.

It can be said that it will be the "universal platform" for the fifth-generation fighter jets, which will greatly enhance the air power of the entire Daxia.

That’s why it’s taken so seriously!
now.

In the huge venue, an aircraft engine was suspended firmly in the air by several angles.

It looks somewhat similar to the WS-10A previously equipped on the J-10, but in various details it is more similar to the F-119 aircraft engine of the Eagle Sauce.

Therefore, it was also internally named the 'WS-119' engine.

Not far away, there is also a very strange fighter jet parked quietly. It also looks a bit like the J-20, but some of its layout aspects incorporate the characteristics of the "F22 fighter jet."

This is the brand new fifth-generation aircraft, the J-22 fighter jet, that the entire research and development team has been working day and night on recently!
Once the aircraft engine 'test run' is successful, the next step is the first flight!

And this time, Song Qinyi’s goal is to succeed and not fail!

This is not the J-20 project, it is something that can be discussed behind closed doors at their 611 Institute.

Currently, Song Qinyi's research and development team has a complete set of "F119 aircraft engine" technical drawings, and also has a double overlay of the actual F22 fighter.

Under such circumstances, the 606 Aero Engine Research Institute, the 624 Aero Engine Research Institute, and the 410 Factory were gathered to provide full support, consuming a huge amount of human and material resources of Daxia.

If this fails, how can Song Qinyi face the "elders of Jiangdong"? How can he explain to Zhang Yuli and his superiors?

Even the 'Great Wall Watch' organization would look down upon Daxia's research and development capabilities, which was something he could not accept.

Under the gaze of dozens of R&D personnel, Song Qinyi's eyes revealed a firmness: "I declare that the test has begun."

As soon as he finished speaking, he quickly pressed a red button on the console.

Instantly, the fierce roar of the engine resounded throughout the venue, and a huge heat wave seemed to penetrate the "high-strength" protective glass and hit everyone's face directly.

The huge energy erupting from the nozzle in the distance was as dazzling as a new rising sun, and a series of Mach rings were clearly visible at the tail.

On the computer screen, groups of data are constantly being calculated.

[Current engine thrust rises to 80 kn↑..89 kn↑]

[The current engine pre-turbine temperature rises. 1300 degrees ↑ 1400 degrees ↑ 1570 degrees ↑ 1660 degrees ↑]

[Engine function is normal]

【.】

Looking at those sets of excellent numbers, Song Qinyi and others became more and more excited.

"The temperature before the turbine meets the standard and should be over 1700 degrees Celsius."

"Its maximum temperature before the turbine can slightly exceed the same level of F119," the deputy next to him said excitedly, and everyone's faces were also filled with joy.

Compared with the WA-10A's turbine inlet temperature, this is a full 300°C increase, and compared with the original Russian AL-20F engine on the J-31, it almost exceeded 350°C.

You know, under the same conditions, every time the temperature before the turbine rises by 10 degrees, it almost means that the maximum thrust of the engine can increase by 20% to %.

(You can also increase the thrust by increasing the bypass ratio, but the disadvantage is that you lose the high-speed capability. This is also the fatal flaw of the 'f35 engine' on the F135. Although it has a large thrust, because the bypass ratio is 0.56, the high-altitude speed is only 1.6 Mach, which is not as high as the cruising speed of the F22 and J-20.)
Therefore, under the premise of allowing high-temperature resistant materials and turbine cooling systems to ensure the service life of the engine, the current global development route for military aviation engines is to significantly increase the pre-turbine temperature to increase its performance.

This 30-degree temperature difference before the turbine results in a maximum thrust difference of nearly %.

What does this mean for a military aircraft engine? It goes without saying!

at the same time.

The two old men far away in Xiake Academy in Yanjing were also anxiously waiting for a report on the specific situation.

“Why is there no news yet?”

"Did something unexpected happen? Or did the experiment fail?"

Zheng Lixing paced back and forth in the office, looking a little restless.

Not only him, but even Zhang Yuli next to him had a deep look of "worry" on his face, as if he was afraid of hearing some bad news.

The two of them have been in this state since they learned at noon that Song Qinyi would conduct a test run of the 'J119' engine in the afternoon.

After all, this engine is too important to Daxia.

It almost determines the development trend of the entire air force's aviation power. How can they not pay attention to it? How can they not be nervous?

at last.

As time passed, the phone on the desk finally rang.

time.

After listening to this very brief phone call, the smile on Zhang Yuli's face was like a bright "flower", and he was so happy.

Seeing this scene, Zheng Lixing knew what happened without asking: "Lao Zhang, is it done?"

"Don't waste your time, tell me what's going on!?"

Zheng Lixing, who is always impatient, spoke quickly, fearing that Zhang Yuli would keep something in suspense and waste time.

Hear the words.

Zhang Yuli did not hesitate too much, but decisively reported a set of numbers.

He said with a smile in his voice: "The performance data of the 'test run' is, intermediate thrust: 126KN, maximum thrust: 156KN, thrust-to-weight ratio is close to 10"

Hearing these numbers, Zheng Lixing's eyes popped out: "How much? The middle thrust is 126kn?"

Not to mention other things, the intermediate thrust alone exceeds that of the original 'F119' engine, and is far superior to the original AL-80F engine which was less than 31KN.

As for other performance data, each one is more outrageous than the last!

"My goodness, Old Song is really amazing!" Zheng Lixing murmured.

This new aircraft engine actually surpasses the F119 in terms of performance. What terrible effects will it have if it is equipped on the J-22 fighter?

Isn't it that the disciple is better than the master, and the waves behind push the waves ahead? Will the Eagle Sauce be beaten to death on the beach with one wave?

These are not just groups of numbers, they are clearly his favorite little cotton-padded jacket!
"Normal. Have you forgotten that we also have the full set of technology for the F135 engine?"

"It's not surprising that you can achieve this by absorbing some advantages." Zhang Yuli said comfortingly at this time.

Although the high bypass ratio of the 'F135' engine is too great a disadvantage, it is not suitable for air superiority aircraft such as the J-20.

But it is undeniable that it is still the best engine currently available.

Whether in terms of thrust performance or fuel efficiency, there are many points worth adopting, and it is very suitable for use in some low-altitude and low-speed attack aircraft or bombers.

If the basic materials for the F135 engine's "variable cycle solution" were not too difficult to master, I'm afraid both engines would have been developed at the same time.

Zheng Lixing was unmoved: "We in Daxia will have an aircraft engine that surpasses the F135 sooner or later!"

This is not only a confidence in Daxia, but also a strong confidence in the technology provided by the 'Great Wall Watch' organization.

"Yeah, that's true." Zhang Yuli nodded. Suddenly, he remembered something more important: "Old Zheng, hurry up and get ready. We'll go to the banquet together tonight."

The diplomatic department has already informed the Saudi ambassador and the Persian ambassador that a secret diplomatic dinner will be held tonight.

Whether good things can come in pairs depends on this time.

(PS: This is the first update... The second update will be here later. If you have monthly tickets, please give them! Please give me monthly tickets at the beginning of the month!
