Xia Yu and Yang Wei were stunned when they heard this, as test pilots, they could still understand, and they specially explained that they also had to be technical consultants, which was a bit interesting. Because generally speaking, when a test pilot is testing a new type of aircraft, what he does is actually similar to that of a technical consultant, there is no need to make a special explanation, what the second chief means by this, is it to let Xia Yu participate in the whole process?

got the affirmative answer of the second chief, whether it was Xia Yu or Yang Wei, the thoughts of the two of them became complicated. It's not that the two of them are ready to intrigue each other, but Yang Wei is very puzzled in his heart. After Xia Yu's identity as a technical consultant was affirmed by the second chief, his authority was almost equivalent to the authority of the chief designer, after all, the technical consultant could only be used to build a new designer, so how could he directly interfere in the design and manufacture of the aircraft?

However, the second leader has already indicated that Xia Yu has this authority, but Yang Wei is still the main one, and the identity of the chief designer is still Yang Wei's, but even so, Yang Wei still has a feeling that Xia Yu ran over to seize power.

And what Xia Yu thought about was much simpler, an airplane that he could toss around? It's exciting to think about, especially when the second chief said at the beginning that this aircraft should be very aggressive, which means that many Xia Yu feel that the technology that can be applied, as long as the country has this technology reserve or is researching, Xia Yu can find a way to apply it to this aircraft, and when he thinks that if this aircraft is really developed and lifted into the air, it is almost equivalent to China's most powerful aircraft at present, Xia Yu is even more excited.

However, Xia Yu is not an idiot, although the second chief gave himself a very exaggerated authority, it does not mean that he can really be the same as the chief designer, and he can criticize this aircraft completely, in that case, it is very unfavorable to the unity and cooperation between the research teams, after all, the development and manufacturing of an aircraft is not something that can be made by a person with a small workshop and casually tinkering.

After leaving Zhongnanhai, Xia Yu immediately told Yang Wei that he would only discuss the development of the aircraft at most, and would not interfere in specific matters, as long as the final design of the aircraft met the requirements of the second chief, Xia Yu would not dictate to the aircraft.

When he said this, Xia Yu played a trick. The second chief's statement was only to ask for radicalism, but Yang Wei didn't know what the specific requirements were, in fact, Xia Yu himself didn't know, but when Xia Yu said this, Yang Wei could only think that Xia Yu had been instructed by the second chief, so he gave Xia Yu this authority far beyond the technical advisor.

In this way, Yang Wei has no way to deliberately snub or squeeze out Xia Yu in the development process of the aircraft, because whether the plane can finally fly and whether it can satisfy the leaders, including the second leader, is Xia Yu who grasps this, at least as it sounds like now.

Xia Yu's little abacus can't say whether he thinks too much, at least now Xia Yu has successfully played this fox and fake tiger drama. After hearing Xia Yu's words, Yang Wei immediately welcomed Xia Yu to join this temporary team, and the two sides would sincerely cooperate and work together.

However, before that, Xia Yu needs to learn and understand the original J-20, and he also needs to actually test fly. Because this technical verification aircraft, temporarily codenamed X20, is an improvement on the basis of the J-20A, it is not all overturned and redesigned aircraft. Moreover, before starting the development of the X20, Yang Wei and his design team also needed to make some modifications to the original radical plan, and Xia Yu just took advantage of this time to learn and test fly the J-20.

Huangtianba Airport, next to it is Chengdu Aircraft Design and Research Institute, this military airport before 2002, even the three words of Huangtianba are highly secret, but now it is completely different, although it is still restricted to ordinary people to enter, but compared to the previous completely inclose to say, now military enthusiasts are much luckier.

Although they will still be driven away, and the filming equipment will be confiscated, this will not stop the enthusiasm of enthusiasts, and many people still run outside the airport every day to see if there are any latest fighter jets in the sky for test flights.

And today, it is destined to be another surprise day for many enthusiasts, because after a few days of ground learning, Xia Yu finally began to fly this fourth-generation heavy fighter developed by Cheng Fei for the first time.

Control the mass-produced J-20A on the runway to carry out the final inspection before take-off, the two engines carried by this fighter are independently produced in China, the first engine with a thrust-to-weight ratio of more than ten, although the life and maintenance time still make the ground crew have a nightmare feeling, but there are no longer any problems in actual use, and its stability is satisfactory, which is also one of the main reasons why the J-20 has the characteristics of a fourth-generation aircraft, and can be finally mass-produced.

The aircraft only taxied a short distance on the runway, and with the help of the vector vent, the J-20 flew to an altitude of 5,000 meters at a very fast speed like a sword piercing into the blue sky.

Level flight, reversal, drum, Xia Yu let himself adapt to the control of this aircraft step by step, and soon, when Xia Yu felt that he had basically mastered the flight performance of this J-20, the adventurous spirit in the test pilot's heart came out again, Xia Yu wanted to know where the limit of this aircraft was.

Let the accompanying J-10B get out of the way, Xia Yu made a request to the tower, probably also to learn about Xia Yu's flight technical ability, Yang Wei, as the chief designer, actually ran to the tower, intending to personally observe Xia Yu's flight watch in the air.

With the permission of the tower, it was opened to Xia Yu for a period of airspace, Xia Yu did not hesitate at this time, and directly pushed the throttle valve to the end, Xia Yu wanted to know what would happen to this J-20A supersonic meter at low altitude.

didn't turn on the afterburner, just full throttle propulsion, Xia Yu watched the airspeed swish upward, with a shock to the fuselage, the J-20 has broken through the speed of sound, when the speed is constant at about Mach 1.5, Xia Yu knows that this should be the supersonic cruise speed of the J-20A. Instead of exiting the supersonic cruise state, maintaining a speed of Mach 1.5, Xia Yu began to control the plane to try to do some flight maneuvers.

Maneuvering at supersonic speed places high demands on the aircraft, especially the aircraft's strength and flight control system. Today's high-tech flight control system can control the pilot's misoperation, especially in the supersonic state, even if the joystick is pulled with all its might, the flight control system will fix the aerodynamic control surface of the aircraft at a certain angle to avoid the pilot's operation error and lead the aircraft to crash.

Maintaining a speed of Mach 1.5 for 6.5G hovering, Xia Yu was happy in his heart, and the maneuverability in the supersonic state is almost a means of killing in air combat, especially in the face of the third-generation aircraft that cannot carry out supersonic cruise, supersonic maneuvering can bring the kite tactics to the extreme. However, in Xia Yu's view, the stability of 6.5G has not played the ultimate potential of this fighter, if the supersonic stability overload can be maintained at 7.5 to 8 G, for Xia Yu personally, it will be even more refreshing.

The J-20 was leveled, the afterburner was turned on, and the WS15, which drank aviation kerosene directly as a drink, began to gush out huge power. The familiar feeling of pushing his back came, and Xia Yu watched the airspeed soar all the way to Mach 2.5, which is basically the highest speed of the J-20A in level flight, but obviously Xia Yu did not stop there.

Slightly depressed the nose of the aircraft, Xia Yu very well put the pneumatic face control zhì on the maximum angle allowed by the flight control system, J-20 immediately began to dive, the black paint made the J-20 dive down from a high altitude look like a black lightning, directly cutting through the sky.

The engine roared, Xia Yu, who had not flown for a long time, couldn't suppress his excitement, the overload force under the supersonic limit could no longer satisfy Xia Yu's desire to fly, and quickly withdrew from supersonic speed to flatten, Xia Yu controlled the J-20 and started a long-lost personal flight show in the sky.
