Concentrate only on the number jù collected from the first flight of X20,Xia Yu has to study the number jù and improvement direction with Cheng Fei's design team during the day,At night, he has to do simulation research with the starry sky,The rest of the time is all with Ye Zi,Not to mention the Internet,I didn't even watch TV,So I don't know when the pictures and videos of X20 are uploaded to the Internet,The uproar it caused。

Although the appearance of the X20 looks like the F22 was revealed, the world was amazed, but in terms of the performance of the X20 aircraft, even the American media that has always advocated Chinese fighters are generally not optimistic.

Distributed photoelectric aperture system and display helmet are the first application of F35, but the design team of Loma company did not dare to be so bold to directly reduce the pilot's field of vision to this point, and X20 actually came from behind, and it seemed to surpass F35, which made the American media with a sense of superiority have expressed doubts about the performance of X20, and finally directly positioned X20 as a technical verification machine, which will not be mass-produced and put into service, which is also a common understanding around the world.

Although this speculation cannot be said to be wrong, or that the research and development of the X20 was originally a technical verification machine, including the first and second chiefs and Cheng Fei, I am afraid that at the beginning, I did not expect that the X20 was restructured from the basic framework of the J-20 after all, no matter how it changed, it did not become a new fighter independently, so no matter how the X20 is improved, the technology that X20 can finally be applied to, J-20 can be used. When the J-20 has been developed and upgraded, the J-20B/C/D/E/F and other models that come out will eventually adopt the technology verified from the X20 technical verification aircraft, that is to say, the official number of the X20 should actually be the J-20X.

However, Xia Yu is not interested in the evaluation of the outside world at all,How to make X20 can become the strongest king of air supremacy is something Xia Yu needs to consider,The design overload of the total control plus or minus 10/4G has reached the limit of manned aircraft,Although Xia Yu himself can resist higher overload force,But these things still can't be realized,Digital array radar is still the development direction of aviation radar at least in the next 20 years,Plasma stealth technology,Airborne power supply technology,Further expansion of the research and development of the gem table, The stability of the optical transmission system, the ability of electronic warfare and even the airborne laser technology, etc., as long as it can be applied, Xia Yu does not want to give up.

The level of domestic scientific and technological research is not much worse than that of the United States, and even slightly exceeded in some aspects, and the real constraint is that the domestic research can not be more efficient in the formation and application of things, such as high-temperature alloy technology, even if a breakthrough has been made, but the yield is low and the output can not be improved, etc., all of which have greatly restricted the manufacture of engines, and this is only one of the aspects, and the things that restrict the development of the country's scientific and technological level are not only these.

In other words, the reason why the No. 1 and No. 2 chiefs and the national think tanks quickly withdrew their troops after breaking through southern Tibet again did not have any influence. After all, the pressure on China caused by Western countries led by the United States is still too great, even if China has formed the world's second largest air force, but compared with the United States, which is more than twice as large as the world's second largest air force, the gap is still too big, not to mention the world's second largest air force, among which a considerable number of fighters are second-generation aircraft such as J-7 and J-8, so they still cannot be compared with the United States in terms of quality.

It is not expected to surpass the United States in a short period of time, but it must not lag behind in high-tech technology, and the national policy of vigorously developing industrial scale will at least keep itself from being controlled by others, the best example of which is India. For example, the famous but accident-prone Su-30MKI inexplicably ejected both pilots during the flight, and finally the plane crashed. This is a testament to India's lack of independent research and development capabilities, as they don't even have the technical ability to digest this fighter.

The progress of X20 is very gratifying, many new technologies have problems in the test and then are solved, which greatly promotes the research and development process of X20, just when Xia Yu thought that he could finish the technical verification of X20 in this way, so that he could go directly to the prototype, and another task came to the door.

"Command vehicle, anti-electronic jamming test ready to begin, ask for permission." At an altitude of 4,000 meters, Xia Yutong guò radioed to the ground to prepare for electronic jamming of himself.

"The command vehicle has received, and the thirty-second countdown to electronic jamming begins."

"X20 understands." Xia Yu replied, and then after the countdown of thirty seconds, the X20's display numbers suddenly shook and immediately returned to normal, a corner of the multiplexing display, representing the red prompt that the aircraft suffered from electronic interference lit up, and at the same time, there was a yellow indicator light indicating that it had been fighting against electronic interference. Xia Yu himself is also involved in the research and development of X20, and naturally knows that he still has the ability to communicate, and the extremely powerful directional digital beam of the digital array radar can allow Xia Yu to talk directly to the ground after locking the communication channel: "The command vehicle can increase the power of electronic interference." ”

"Command vehicle received." Hearing Xia Yu's clear voice from the radio, Yang Wei was very excited, under the electronic interference of this power, Xia Yu's voice was so clear that it sounded in the command vehicle as if it had not been affected at all, that is, X20 At least in the face of electronic warfare aircraft, X20 will hardly be affected in any way, it seems that the excellent performance of the all-digital array radar system does live up to expectations.

Continue to increase electronic interference,X20In the cockpit,Xia Yu doesn't even need to look down at his multi-function display,Virtual 3D display helmet automatically projects all kinds of information into Xia Yu's eyes,According to the movement of Xia Yu's pupils,The display helmet will automatically amplify the information,Let Xia Yu see more clearly,Then Xia Yu continued to say to the ground command vehicle:"At present, the number of jù load has increased by 14%, the full load is 67%, how is the communication effect?" ”

"It's very clear." Yang Wei's slightly excited voice came into Xia Yu's headphones: "At present, the straight-line distance between the two interference sources and you is 2397 meters and 1874 meters respectively, and the operating power of the interference equipment is 80%, and there is no sign of interruption in communication now, what is the overall load of your airborne system?" ”

His eyes moved, and Xia Yu reported the information he saw: "The system load is 52%, and all functions are normal." ”

"Great!" Yang Wei jumped up happily, waved his hands twice involuntarily, and then picked up the microphone and said, "Test the number of basic load expectations, you can return." ”

"Roger." Xia Yu was also very happy, after getting the order to return, he actually pulled up X20 to make a maximum instantaneous disc angle, X20 was extremely flexible in the air and then lifted the nose, the sudden formation of the air pressure difference made X20 suddenly put on a white dance skirt, the vortex of the body was stirred for a while and then disappeared, and X20 also completed the U-turn, ready to enter the landing procedure, but at this time, Wu Jianming's voice suddenly came from the radio: "Dragon teeth, immediately turn to 270, ready for battle." ”
