Of course, this is not how the account is calculated, after all, the production line itself is still valuable, and it is not so easy for military enterprises to return to their original costs in a short period of time.

Today's day was specially chosen, this is a military area itself, and it is impossible for ordinary people to take photos of this airport, which is not the same as when the J20 was tested before.

In addition, today's weather, the sky has very thick clouds, in which case both optical and synthetic aperture radar will almost be useless.

While synthetic aperture radar can sometimes be weather-free, it is not possible to be completely unaffected by the weather.

Under such weather conditions, it is estimated that the synthetic aperture radar will not be able to distinguish what kind of fighter is going on.

Although optical satellites can penetrate a certain layer of clouds, there is absolutely no way to penetrate such thick clouds.

The door of the hangar gradually opened, and a trailer had already driven in directly, and Jiang Yanhai also saw Colonel Huang Yao at this moment, a national special pilot, and a special test pilot.

After the two saluted, and then shook hands again, Huang Yaocai smiled and said: "Hai Dongqing, I've heard it for a long time, you can be an ace pilot, but I don't know, you are still a fighter designer." ”

"There's no way, if you want to drive a better fighter, if you don't, then you can only design it yourself." Jiang Yanhai made a joke, "It's up to you today." ”

"Don't worry." Huang Yao took a deep breath, he also raised his head to look at the phantom next to him, and then spoke again, "You can see that this is a big guy." ”

The first test flight of J20 at that time was also completed by Huang Yao, and at this moment, the phantom was handed over to him, Jiang Yanhai had nothing to worry about, but unfortunately Liu Lao didn't let him get on it himself.

"Well, and it's definitely more powerful than you think." Jiang Yanhai smiled slightly.

"I've heard about it, but I just don't know when I'll be able to test its limits." Huang Yao was also a little excited, of course he had to know everything about fighter jets as a test pilot, so of course he knew the Phantom's data.

"I'll wait for you at the tower." Jiang Yanhai saluted Huang Yao.

"Yes!" Huang Yao also returned the salute, and then turned around and walked towards the fighter.

Li Ruobai was already at his job, and Jiang Yanhai also turned around and walked quickly towards the tower.

When Jiang Yanhai arrived at the tower, it could be seen that the phantom had been dragged out by the trailer, and the trailer had been evacuated, and there was not much fuel added to the phantom, so as not to release fuel when landing for a while.

So the fuel is probably only about a third of the way up.

"The tower calls the crane." Jiang Yanhai picked up the front one of the red intercoms on the tower table.

"Crane received."

"Crane, the airspace has been cleared, you can start." Jiang Yanhai glanced at the data of the operator next to him, and then spoke.

"Crane received."

The Phantom was dragged directly to the .asxs. part of the run, because although the engine has been rigorously tested, but after installation, no one knows if there will be problems, so the first time is naturally in the safest place.

Jiang Yanhai followed the distance in front and looked at the phantom on the runway in the distance, and after he sent out dozens of seconds, the tail of the phantom spewed out orange-red flames violently.

"Yay!" Not only Jiang Yanhai was paying attention to the tower, but other operators were also paying attention, and they couldn't help but wave their fists when they saw this scene, and couldn't help cheering.

Starting the engine is a good step, Huang Yao did not take off as soon as possible, but was constantly adjusting and adjusting the various parts of the Phantom, canard wings, tail wings, etc., and he was still communicating with Liu Lao and them.

After about seven or eight minutes, after about some tests that needed to be done on the ground, Huang Yao directly began to push the throttle valve, and the phantom began to slide into a state.

However, the first Phantom does not take off, but accelerates to take-off speed, then gradually slows down, then taxied around the runway, then returns to .asxs., and then does a second ignition.

Soon, the first glide was perfect, and the Phantom slowed down to the other end of the track, then made a big circle from the auxiliary track next to it, and taxied to the .asxs. of the track, repeating the previous test.

Then the Phantom started the second test, this time Huang Yao directly pushed the throttle valve, but he didn't take off at the fastest speed, so the Phantom took a slight leap after taxiing for nearly four hundred meters and went directly into the air.

It starts to climb in the smoothest of its stance, but it doesn't climb too high, no more than a kilometer or so, and it circles around the base a few times.

"Crane, how's it going?" Jiang Yanhai asked.

"The stance is smooth, the handling is very light, and ...... Powerful! Huang Yao's emotions were a little excited, because he knew that the biggest change in the phantom was about power, cruising can reach Mach 3 speed, afterburner limit speed Mach 4, so I asked you if you are afraid?!

"Okay, let's start testing gradually." Jiang Yanhai said directly, he didn't join in the rest of the matter, and Liu Lao and the others began to direct Huang Yao over there to start all the tests step by step.

In fact, when a new fighter goes into the sky, the engine is most likely to go wrong, after all, if the engine is broken, the plane will be finished.

And for example, if the engine is not broken, even if the electronic system is broken, there is no problem for the time being, at least the plane will not crash.

An experienced pilot like Huang Yao can land even visually.

In addition, the body structure is also the focus of the test, but the body structure, generally not carried out a large maneuver test, it is difficult to have problems, after all, the current technology, these aspects of the problem is more difficult.

In the past, fighter landing gear was a difficult point for the country, but now it is not a problem. In the past, there was no die forging machine in China, and even an aircraft landing gear could not be manufactured, but now China has the world's largest 80,000-ton die forging press!

These are no longer a problem, and it is said that a 160,000-ton die forging press is now being designed and built! This thing is also a real national weapon!

This thing really represents the pinnacle of heavy industry in the world, and the die forging press is more than 40,000 tons, which is currently only available in China, the United States, France and Russia.

The first test flight will not take too long, about twenty minutes or so, Huang Yao will operate the fighter to land, and then, the entire phantom will undergo a comprehensive inspection.

Looking at the Phantom fighter that completely landed over there, a stone in Jiang Yanhai's heart finally landed, no matter what, this is the perfect start!

And at this time, suddenly in Jiang Yanhai's mind, the voice of the long-lost Red Star Engine suddenly appeared.
