Chapter 163 Success! Yingjiang has an F119 engine, what’s wrong with our Daxia having a WS-119? !
A quarter past three in the afternoon.
In this Gobi Desert filled with yellow sand, the sun hanging high above the sky shines on this land.
Huge buildings rise abruptly here, creating a strong contrast with the surrounding environment.
Whether it is located in an uninhabited land or the dozens of kilometers around it are all designated as military restricted areas, they all symbolize its extraordinary status.
“This place is suitable for aviation research and development.”
"It's just that the environment is too harsh and it's too inconvenient to live in for a long time." Song Qinyi once again sighed from the bottom of his heart.
The Gobi Desert has a dry climate with neither high nor low temperatures, which is the most suitable place for aviation research and development.
After all, modern fighter jets are no longer the antiques of the last century. They are purely mechanical and have little impact on extreme weather.
Like today's fourth- and fifth-generation fighter jets, they integrate sophisticated components such as avionics and radar fire control.
Once the temperature is too humid, it may cause high-precision damage. As for the corrosiveness caused by excessive salinity, excessive temperature, etc., it may even cause the overall control system inside the fighter jet to fail on the spot.
But the shortcomings are also obvious. The Gobi Desert in Northwest Province is too remote, and the convenience of life is equal to zero.
If R&D work is carried out for several years here, it may be a great test for the spirit of every R&D personnel.
Song Qinyi stared at the aircraft engine in the distance and muttered slowly: "I think it won't take that long."
At this time, an engineer with a shiny forehead came next to him, holding a stack of drawings in his hand.
"Gong Song, all tests have been completed, and the engine 'trial run' test can begin."
The aero-engine ‘commissioning’ test is the stage of complete testing of an entire aero-engine.
If the regular tests are divided into assessments one after another, a successful first flight is the 'college entrance examination', and the 'test run' test is the last monthly examination.
Generally speaking, as long as the 'test run' is successful, the next stage will be to equip the fighter jet for its final first flight.
"I understand." Song Qinyi nodded seriously.
For Daxia, which has already achieved a successful first flight of the J-20, whether this engine can be successfully 'tested' is of great significance.
Once successful, according to the original plans, it will be equipped on future fifth-generation fighter aircraft such as the J-35 and J-31, and will also be deployed on various derivative models such as the J-10 and J-15.
It can be said that it will be the 'universal platform' for fifth-generation fighter jets, which can greatly enhance the air power of the entire Daxia.
That's why it's so valued!
now.
In the huge venue, an aerospace engine was hung firmly in the air at several angles.
Its appearance is 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 Yingjiang.
Therefore, it was also named the ‘WS-119’ engine internally.
And there is a very weird fighter jet parked quietly not far away. It also looks a bit like the J-20, but in some aspects of its layout, it also incorporates the characteristics of the 'F22 fighter jet'.
This is the new fifth-generation aircraft that the entire R&D team has recently developed day and night, the J-22 fighter jet!
Once the aircraft engine is successfully ‘tested’, the next step is the first flight!
And this time, Song Qinyi’s goal is to only succeed and not fail!
This is not the J-20 project, it is something that can be discussed behind closed doors at their 611 Research Institute.
At present, Song Qinyi's R&D team has a complete set of technical drawings of the 'F119 aeroengine', and also has a double superposition of the actual F22 fighter jet.
Under this situation, the 606 Aviation Development Research Institute, the 624 Aviation Development Research Institute, and the 410 Factory gathered all their help, which consumed a huge amount of human and material resources in Daxia.
If this still fails, how can he, Song Qinyi, still have the face to meet the ‘Jiangdong elders’? How to explain to Zhang Yuli and his superiors?
Even the Great Wall Watch organization would underestimate Daxia's research and development capabilities, which was something he could not accept.
Under the gaze of dozens of R&D personnel in the audience, Song Qinyi's eyes showed firmness: "I announce that the test has begun."
As soon as he finished speaking, he quickly pressed a red button on the console.
In an instant, the violent roar of the engine resounded throughout the entire venue, and a huge heat wave seemed to pass through the 'high-strength' protective glass and directly hit everyone's faces.
The huge energy erupting from the vent in the distance was as dazzling as a new sun rising, and a series of Mach rings were clearly visible at the tail.
On the computer screen, groups of data are being continuously calculated.
[The current thrust of the engine has increased by .80kn↑..89kn↑]
[The current temperature in front of the turbine of the engine has increased. 1300 degrees↑1400 degrees↑1570 degrees↑1660 degrees↑]
【Engine function is normal】
【.】
Looking at the groups of outstanding numbers, Song Qinyi and others became more and more excited.
"The temperature in front of the turbine reaches the standard and should exceed 1700 degrees Celsius."
"The maximum temperature in front of the turbine can slightly exceed the same level of the F119." The deputy next to him spoke with excitement, and everyone's faces were also filled with joy.
Compared with the WA-10A's turbine front temperature, this is a full increase of 300°C, and compared with the old AL-31F engine on the original J-20, it is almost more than 350°C.
You know, under the same conditions, every time the temperature in front of the turbine rises by 100 degrees, it almost means that the maximum thrust of the engine can increase by 10% to 20%.
(Thrust can also be increased by increasing the bypass ratio, but the disadvantage is that it loses high-speed capability. This is also the fatal flaw of the 'f135 engine' on the F35. Although its thrust is large, because the bypass ratio is 0.56, The high-altitude and high-speed speed is only Mach 1.6, which is not as high as the cruising speed of the F22 and J-20)
Therefore, with the permission of high-temperature-resistant materials and turbine cooling systems to ensure the service life of the engine, the current global development route for military aerospace engines is to significantly increase the temperature in front of the turbine to increase its performance.
This 300-degree temperature difference in front of the turbine is almost more than 30% of the maximum thrust difference.
What does this mean for a military aircraft engine? That goes without saying!
At the same time.
The two old men at the Summer Academy of Sciences in Yanjing are also anxiously waiting for reports on the specific situation.
"Why no news yet"
"Did something unexpected happen? Or the experiment failed."
Zheng Lixing was pacing back and forth in the office, looking a little restless.
Not only him, but also Zhang Yuli next to him had a heavy look of 'sadness' on his face, for fear of hearing some bad news.
The two of them have been in this state since they learned at noon that Song Qinyi was going to conduct a test run of the 'J119' engine in the afternoon.
After all, as I said before, this engine is too important to Daxia.
It almost determines the development of the entire air force's aviation power. How can they not pay attention to it? How can you not be nervous?
finally.
After minutes and seconds passed, finally, the phone on the table rang.
time.
Just after listening to this very brief phone call, the smile on Zhang Yuli's face was like a bright "flower", and his smile was so happy.
Seeing this scene, Zheng Lixing knew what happened without asking: "Lao Zhang, is it already done?"
"Stop whining and whining, tell me what's going on!?"
Zheng Lixing, who has always been impatient, said quickly, fearing that Zhang Yuli would try to make trouble again and waste time.
Hear the words.
Zhang Yuli did not hesitate too much, but decisively reported a set of figures.
He said with a smile in his voice: "The performance data of 'test run' are: intermediate thrust: 126KN, maximum thrust: 156KN, thrust-to-weight ratio close to 10"
Listening to these numbers, Zheng Lixing's eyes popped out: "How many? The middle thrust is 126kn?"
Not to mention other things, the middle thrust alone has exceeded the original 'F119' engine, and far exceeded the original AL-31F engine which was less than 80KN.
As for other performance data, they are even more outrageous than the last!
"What a great guy, Old Song!" Zheng Lixing murmured.
This new aero engine actually surpasses the F119 in terms of performance? If this is equipped on the 'J-22' fighter jet, what terrible effects will it have?
Isn't it true that the young is better than the blue, and the waves behind the Yangtze River push the waves ahead? Just hit Yingjiang to death on the beach with a wave?
This is not a set of numbers. This is clearly his favorite little cotton-padded jacket!
"Normal, have you forgotten that we also have a full set of technologies for the F135 engine?"
"It's not surprising that we can do this by absorbing some advantages." Zhang Yuli said with relief at this time.
Although the large bypass ratio of the 'F135' engine has too many disadvantages, it is not suitable for air superiority airframes such as the J-20.
But it is undeniable that it is still the most excellent engine currently.
Whether in terms of thrust performance or fuel efficiency, etc., there are many points worth adopting, and it is very suitable for use by some low-altitude and low-speed attack aircraft or bombers.
If it weren't for the fact that the basic materials of the "variable cycle solution" of the F135 engine were too difficult to overcome, I am afraid that both engines would have started development at the same time.
Zheng Lixing was unmoved: "Sooner or later we will have an aero engine that surpasses the F135!"
This is not only confidence in Daxia, but also strong confidence in the technology provided by the 'Great Wall Watch' organization.
"Well, that's true." Zhang Yuli nodded, and suddenly he remembered a more important thing: "Old Zheng, hurry up and get ready, and we will have a banquet together tonight."
< br>
The Ministry of Foreign Affairs has informed the 'Saudi Ambassador' and the 'Persian Ambassador' that a secret diplomatic dinner will be held tonight.
Whether good things come in pairs depends on this time.
(PS: The first update. The second update will be here later. If you have a monthly pass, you can give one! Please give me a monthly pass at the beginning of the month!
