As the so-called glimpse of the whole leopard, a qualified passenger aircraft is nothing more than those characteristics, one is the stability of the aircraft structure, and the other is the safety of the aircraft.

These two factors sound simple, but in fact they are hindering the pace of countless companies around the world that want to enter the field of passenger aircraft construction, just like a huge threshold, countless people want to step over, and the result is that they are all falling into a.

Although this passenger aircraft has just been assembled and has not yet carried out large-scale test flights, it has already shown the world that the stability of this passenger aircraft in the structure of the airframe is not even inferior to those military transport aircraft.

At the same time, the working efficiency of the engine is also very stable, and there is no strike under such a limit climb, which also shows that this engine is mature enough.

However, a lot of test flights are still needed, because even if those airlines are tempted, the most they can do is send a letter of intent to buy.

As for whether it will be bought, it depends on the price and cost performance, of course, the most important thing is that this passenger aircraft can carry out every kind of test flight, then carry out high-density global flights, and finally get various licenses.

Adapt to stable work under various conditions such as different climates, different altitudes, different humidity, different temperatures, etc.

In this way, airlines from all over the world can be satisfied with the purchase, after all, an aircraft that can adapt to various regions and climates around the world is a mature aircraft.

This kind of requirement is not only for military aircraft, but also for civilian aircraft.

Then, when the data from these test flights is combined, the flight of the airliner in different climates and conditions is also compared. Organize it into a manual. Put it on the plane and sell it together.

The airline that bought this passenger plane in this way. will understand how to better operate this passenger plane.

Therefore, the test flight still has to continue, not to say that this can save the time of the test flight, which is simply impossible.

At the same time, the large technology did not take off, but just circled the runway of the airport and began to taxi on its own.

This is a simple glide test. Such a test is also very necessary, mainly to see how the engine operates at low power.

The passenger plane in the sky, after rising to 15,000 meters in the air under the control of Zhao Yunlong, immediately modified its flight attitude and maintained it behind the attitude of level flight.

Then it began to fly around the sky above the town of Marin, and began to fly around.

At this time, a Russian Su-30SM fighter appeared under it, as well as an F-16 fighter, and at an altitude of five thousand meters, there was a Global Hawk.

As for those two fighters. They all just came over to see the excitement.

Just fifteen thousand meters at an altitude to let these two fighters. I don't dare to come up easily.

However, for this black airliner, there are no such concerns, because its technical performance is to allow it to maintain this altitude and carry out subsonic cruise flights.

Soon, under the pilot's operation, the black airliner soon reached subsonic high speeds.

Even those two fighters had to accelerate to be able to keep up below.

At the same time, the pilots of these two fighters also exclaimed at the same time, they did not expect that a passenger plane could actually fly to 1222 kilometers per hour, and it was only 18 kilometers per hour before breaking the sound barrier.

However, it seems that the test pilot above really doesn't feel enjoyable, under the voice of the two pilots who exclaimed again.

A loud sonic boom came from the airliner they were following, and the body of the airliner seemed to be stretched a little at once, and then quickly shook off in front of their eyes.

If it weren't for the lack of humidity here, it would have been spectacular for such a huge airliner to enter a sonic boom cloud formed at supersonic speeds.

The pilots of these two fighters were very depressed to find that they were actually thrown away by a passenger plane.

However, the F-16 and Su-30SM also all entered supersonic flight at once, and all of them were raised to Mach two in one go.

Only this time they didn't hear the sound of the sonic boom again, because by this time they had broken through the sound barrier, and the speed had exceeded the speed of sound propagation, and the sound barrier was issued at the rear of the plane, and the cockpit was in front, so naturally they couldn't hear it.

The two pilots could not feel the speed of sound, so they could only look at the instrument panel, and after seeing that the sound barrier was successfully broken, they drove up with full horsepower.

However, on the ground, everyone was shocked to listen to three huge sonic booms, and many people with binoculars watched a passenger plane and two fighters flying at high altitude with some sluggishness.

This is simply unseen and unheard of, and this is probably another passenger plane that can enter the supersonic team, except for the fact that all the supersonic passenger planes in France have been grounded until now.

However, the corners of Cai Ruichen's mouth twitched a few times, and he found that he was really going to be scared to death by that Zhao Yunlong.

I just came to the extreme flight that makes my heart beat faster, and now I actually drove a passenger plane into supersonic flight.

You must know that the airliner itself does not have the indicators of being able to enter supersonic flight, at most it is at an altitude of 12,000 meters in thin air and enters subsonic flight.

But now, he was able to soar high in the sky with two fighters, which once again shocked everyone's eyes.

Those who were watching the live broadcast were all hooked, because they could clearly see the three planes flying in the air.

I have seen the confrontation between fighters, but the confrontation between passenger planes and fighters is still two different models, representing the main fighter models of NATO and Russia flying together.

I am afraid that I will never see such a scene in my life, but it is a pity that a passenger plane is a passenger plane, and after entering the supersonic speed, the speed is at most Mach 1.2, and the two fighters, with a high speed of Mach 2, quickly caught up.

However, this is when the endurance showed itself, and the airliner still maintained a speed of Mach 1.2, while the speed of the two fighters began to decrease.

Because they still have to save fuel to return to the airport, fortunately, they still catch up, otherwise it will be really embarrassing.

Subsequently, the passenger plane ended its supersonic flight, and then slowly descended to an altitude of 10,000 meters.

The two fighters, one on the left and one on the right, also accompanied it to fly, and at this time, the two test pilots on the passenger plane waved their hands to the pilots of the fighters on both sides.

Even, the drivers of the three parties all took out their cameras, took pictures of each other, and then waved their hands again and made a farewell gesture, and then separated.

Both fighters are heading back to their airfields, and this airliner continues its test flight project. (To be continued.) )
