Shengjing in October has become cold.

Most of the pedestrians on the street wore thick winter coats.

At this time, all kinds of down jackets were not yet popular, and of course most people did not have that much money to buy down jackets.

Most of them still wore thick and warm military coats, and the few who got rich first and had a little money wore fur coats.

At a military airfield in the cold wind, a Su-27 painted in sky blue is quietly waiting on the tarmac.

The hearts of the people around it did not cool down because of the cold, and it can even be said that everyone's hearts were like a raging fire.

Except for Zhang Xingyang, who was specially invited to watch the first trial of the WS-10, most of the old people who have worked hard for the WS-10 project for many years were present.

Everyone watched the results of their years of hard work finally usher in the actual test, just like their own children are about to go to the examination room.

While I was happy, I was very nervous.

The pilot of the Su-10, which was replaced with a domestic WS-27 engine, was a special pilot from the Air Force test flight team, Lei Yong.

Lei Yong has been training for the test flight of the domestic third-generation aircraft J-10, and let him make the first flight of the WS-10, and also consider preparing for the test flight of the J-10.

"Major Lei, are you sure about this flight test?"

Before the official start of the flight test, Zhang Zhengjiang asked him a little nervously.

It is no wonder that Zhang Zhengjiang is nervous, this test flight is related to the future direction of the WS-10 project.

If the WS-10 engine really performed very poorly in the test flight, then the upper side would definitely make up its mind to introduce the AL-31F engine from the north Da Mao's house.

At that time, even if the WS-10 project team is not abolished, the degree of attention will definitely be greatly reduced.

"Comrade Chief, I promise to complete the task at any cost!"

Lei Yong did not directly answer Zhang Zhengjiang's question, but gave his own answer from his own perspective.

Everyone present also knew what this answer meant.

If there is any accident in the flight, the opponent will do everything in its power to complete the flight test.

Even if it's to give your own life!

Seeing the firm and resolute decision of the test pilot, Zhang Zhengjiang didn't say anything more, but saluted a military salute:

"Thank you!"

The aircraft tractor slowly dragged the Su-27, loaded with the hopes of everyone present, out of the tarmac.

After all the preparations were completed, Lei Yong, who was already sitting in the cockpit, raised his thumbs outside.

Accompanied by the tower giving the command to take off.

The WS-10 engine in the tail of the Su-27 spewed orange flames, which began to turn blue again as the plane slowly taxied.

This means that the temperature of the engine is constantly rising, and it is about to reach its operating temperature.

In general, the Su-31 fighter, using the AL-27F engine, has a take-off run distance of about five hundred meters without afterburner.

The current WS-10 engine thrust is 130KN, while Maozi's AL-31F thrust is at 135KN.

So after the replacement of the WS-10 engine, the thrust of the Su-27 engine decreased.

The corresponding land glide distance is also slightly longer.

After taxiing a distance of six hundred meters, Lei Yong drove the Su-27 from the airfield.

Like a war eagle about to launch an attack into the sky, soaring into the sky.

The first test flight did not do all kinds of maneuvers, Lei Yong just flew two laps in the sky with the Su-27 fighter, and the absence of problems means that the flight test was essentially successful.

However, it seems that he only flew two laps, and Lei Yong was not very satisfied, and proposed to the command center that he wanted to fly two more laps.

"Command center, apply to fly two more laps."

During the previous flight, the WS-10 did not show any problems, so Zhang Zhengjiang, as the commander present, agreed to the test pilot's request without hesitation.

After flying like a war eagle in the air for two laps, the Su-27 completed the entire test flight process.

As a driver, Lei Yong also wants to give everyone a trick and perform the Cobra maneuver that made the Su-27 famous in World War I.

Everyone present also wanted to see how far the domestic engine could go, so they all looked at Zhang Zhengjiang in the command center.

And Zhang Zhengjiang, as the top person in charge of the entire test flight process, naturally wants to see how far the WS-10 can go.

So he agreed to Lei Yong's request.

After the Su-27 fighter circled in the air for a while, Lei Yong maintained the fighter's speed at about 420km/h, and then pulled the lever back, allowing the fighter's nose to tilt back 120 degrees.

So the sky blue fighter jet, the tail in front, the nose in the back, the whole fighter as if leaning backwards.

At this time, Lei Yong continued to increase thrust to press the nose of the Su-27 fighter, so that the fighter returned to its original horizontal flight state.

Seeing Lei Yong complete this climactic difficulty that shocked the world at the air show only a few years ago.

The people in the command center couldn't help but applaud.

Zhang Zhengjiang, as the person in charge, was no exception, and said to the people around him while failing again:

"We made it!"

"We finally have our own high-thrust military engine belonging to the Dragon Country!"

"From now on, we don't have to look at the faces of those foreigners!"

As an old man over half a hundred years old, Zhang Zhengjiang has been experiencing an era when domestic engine technology is not as good as others.

This is also why he was so excited after seeing the Su-27 make a Cobra maneuver.

He had waited too long for this day.

As for Zhang Xingyang, who was standing behind him, he was also a little emotional.

Only when we are truly in touch with this era can we feel the pressure of everyone at this time in the face of foreign military blackmail.

Looking at the Su-27 slowly landing over the airport, Zhang Xingyang thought. In the future, it is estimated that the scene of Maozi blackmailing us with the AL-31F engine will not appear again.

The Su-27 fighter slowly stopped at the end of the runway of the airport, and before Lei Yong could open the flight hatch.

The enthusiastic crowd had already poured around the plane.

After Lei Yong carefully climbed off the plane, he came to Zhang Zhengjiang and saluted excitedly:

"Report to the chief, test pilot Lei Yong successfully completed the test flight mission! Please instruct! ”

Zhang Zhengjiang was also very excited, held Lei Yong's hands and said:

"Thank you for your hard work, you are the hero of our Air Force!"

At this time, the other people present were also very enthusiastic and stepped forward to hug Lei Yong.

Even Zhang Xingyang was no exception, he was infected by the warm atmosphere present and hugged the test pilot hero.

In this way, in a happy atmosphere, the WS-10 engine successfully completed its first air operation.

Although the extreme performance of the engine has not yet been tested, the complete success of this test flight still gives everyone a lot of confidence.

At the very least, this represents the progress of the WS-10 project, and the first engines that can be used in real life have been built.
