Chapter 225: The first test flight

December 21

The Mayan calendar ushered in a new era, triggering an upsurge about the mysterious legends of the Maya, and the Mayans once again entered people's sight.

Many young couples spend this day on the big bed in the hotel. If it is true as predicted by the Mayans, they will taste the forbidden fruit before they die, knowing the beauty of the love between men and women, and they will die holding each other together.

Many young couples found a lawn or at the beach, hugged each other, and promised to die together for three lives and three lifetimes, promising each other that "there are no mausoleums in the mountains, and the heaven and earth are harmonious, so I dare to be with you forever!"

That night, countless boys became men and countless girls became women!

But after one night, nothing happened. I don’t know how many men were very proud, and I don’t know how many women regretted it.

However, Qin Yuanqing left the capital and went to AVIC Chengdu Aircraft Industry Group Company.

Because on this day, the J20B equipped with the Everest aviation engine will conduct its first test flight. The previous successful test flight was named J20A.

The military attached great importance to this test flight. Many leaders came to the test flight site in person. Looking at the aircraft, which was 67% similar to the American F22 and like twin brothers, Qin Yuanqing felt strange in his heart. If the American Will people vomit blood when they see this plane?

The weather conditions today are very good and suitable for test flights.

The J20B has a number 01 on the side of its nose, which is very eye-catching. Beside the plane, five people had their hands behind their backs and looked serious.

Qin Yuanqing and others were on the rostrum, waiting for the test flight. Yang Wei, as the chief designer, was introducing the test pilot to everyone.

The test pilots who can be selected as J20 are all ace pilots. They are selected from tens of millions of people and have very rich experience. It can be said that every test pilot is a precious asset of the country. We must cultivate a Excellent test pilots require the investment of a lot of resources.

"The weather conditions meet the requirements and the test flight is ready!" In the tower, the weather conditions were being reported.

Flight conditions are very limited by meteorological conditions. Once the meteorological conditions are not met, the test flight cannot be carried out, otherwise it will be very dangerous.

The test pilot selected for this time started to wear anti-German suits and was about to start wearing a helmet!

And one of the leaders smiled and said: "Let's go to the airport together!"

"The report is ready and ready for test flight at any time!" The test pilot saluted everyone.

Yang Wei introduced: "This test pilot is called Li Gang. He has rich test flight experience and is a dedicated J20 test pilot. This time he was still chosen for the test flight."

Qin Yuanqing looked at these five test pilots. These five were all ace pilots. They all knew that test pilots were an extremely dangerous industry and there was always the possibility of sacrifice. However, they had advanced fighter planes for the sake of the motherland. There was no hesitation at all, even if it meant sacrifice.

China's air force can develop and grow step by step, which requires a lot of blood and tears, and is earned by countless people who are not afraid of sacrifice.

The leader gives a speech.

Li Gang saluted the leader and said: "Don't worry, leader, even if I, Li Gang, break my arm or leg, I will fly the plane back! Even if it falls, I will fall on the runway! I will definitely let us know all the hard work for so many years." Try hard to find out what went wrong!”

After hearing Li Gang's words, many people's eyes immediately became wet! This was completely determined to say goodbye, but Li Gang was very calm and did not write a suicide note. How many people can possess this kind of fearless spirit?

Although it has been tested many times on the ground, it has not yet flown. Therefore, any situation will occur. For example, if the ground test goes well, after flying, the aircraft will not move at all when it is time to pull the lever. At that time, the aircraft was completely uncontrollable.

Even in previous test flights, there were test pilots who lost their engines while the plane was flying, and then crashed and crashed, killing everyone!

After Li Gang paid a military salute to everyone, he began to walk towards the plane, lowered his head and passed through the nose of the plane to conduct routine inspections of the plane.

This is what any pilot would do. Although the ground staff has already done a good job, it must be checked personally before getting on the plane.

Just like the pilots in the past, the parachute must be folded by oneself, because the one who really needs to use it is oneself, and it is definitely not safe to let others fold it.

There are many items to check. As usual, Li Gang starts from the front landing gear, checks the air pressure of the tires, whether there is hydraulic oil leakage from the front wheel strut, whether the wires inside are worn or leaked, and then checks the air intake duct. Is it normal? . . . .

When on the ground, the rudder surfaces are fixed with fixed wedges. Before taking off, these need to be removed. In order to be conspicuous, they are all marked in red. Li Gang went around in a circle to check various devices, and then Just look at the tail fins, tail nozzle, drag chute, and rudder.

After checking once, in the opposite direction, he checked a second time. When all checks were completed, Li Gang signed the book handed over by the ground crew and picked up the helmet.

Then Li Gang climbed up the gangway, and the ground crew followed him up, helping to fasten the seat belts and check the seal of the canopy. When the canopy was buckled and the gangway was removed, everyone's hearts were lifted.

"01 report, the system has been started and everything is normal!"

"Check again!"

"01 understand, the inspection is completed, everything is normal!"

"Get ready, drive!"

As the command system issued instructions, the engine started. With the sound of the motor, the whistling of the turbine gradually became sharper. After a minute, the engine ran stably and the engine started successfully!

But no one applauded, because everyone knew that this was just the beginning!

For the flight test evaluation of aeroengines, the first thing to do is to fly the aircraft, which is the most important, and then to test the performance and indicators of the aeroengine in flight.

Qin Yuanqing also looked serious at this time, because there are many uncertain factors when an aero engine is mounted on a plane. Once there is a problem in any link, there may be serious consequences.

Although this is also a J20 fighter, it is very different from the J20 fighter that had successfully tested before. Therefore, it is better to call it a test than the first test flight.

Qin Yuanqing listened to the sound of the engine. He watched the plane slide out of the apron and onto the runway attentively. Qin Yuanqing could only hope that if any problems occurred at this stage, it would be very dangerous if the plane took off and appeared again. It has increased by 10 times. If it is serious, the machine will be destroyed and everyone will be killed, without even a chance to save it.

The aircraft quickly began to taxi forward. The J20B fighter was a heavy fighter, weighing 15 tons in the air. It was supposed to be equipped with two Everest aircraft engines, which could allow it to take off in a short distance. However, the test pilot was very cautious and taxied for a certain distance before taking off.

I saw the J20B fighter jet, like a raptor, rushing towards the sky! This is its first flight.

On the ground, Qin Yuanqing and others looked at the J20B fighter plane flying into the sky, but they did not relax at all, because as long as the plane did not land safely, it meant that there might be risks at any time.

Everyone was waiting at the airport, waiting for the plane to come back and land safely. No one left alone, and no one spoke. From the control tower, contact with the test pilots was constantly coming. Judging from the current feedback, everything was fine. very smooth.

When the J20B fighter jet flew back, it did not land directly. Instead, it made an application to fly one more circle! And the leader agreed.

And the crowd burst into applause and cheers, and everyone was jumping and jumping excitedly. Everyone on the podium couldn't help but get excited when they saw the plane approaching again, almost. Everyone is wiping their eyes.

After all, this is a fighter jet developed by China itself, and the test flight went so smoothly!

Although everyone has not personally flown the plane, they can feel the powerful power bursting out from the aircraft's aero engine, and the powerful roar makes people's blood boil.

The plane began to descend, then landed safely, and began to stop steadily at the end of the runway. The entire airport burst into warm applause, and everyone ran to the end of the runway like sea water. Everyone's hearts were full of excitement and joy. Excited.

The tractor came over, ready to tow the plane back, and the ramp was set up. When the canopy was opened and everyone saw Li Gang, everyone couldn't help but applaud and cheer to welcome this hero.

It was also the first time for Qin Yuanqing to watch the test flight of a fighter jet in person. He felt the same way and was equally excited and proud.

Aviation engines have always been the heart disease of the Chinese Air Force, plaguing China. A heart attack may occur at any time, which can be fatal.

But now, for the first time, the Everest aviation engine is mounted on a fighter plane, and the test flight is so smooth and successful, it almost means that China's heart disease has been completely solved.

Although he knew that a test flight test was nothing, the entire test flight process was a long process that required testing all aspects, such as the maximum flight altitude, maximum flight speed, maximum flight distance, and short-distance takeoff and landing. . . . . .

It even includes a series of tests such as maximum speed duration, combat radius test, etc. The previous J-20 took six years from the successful test flight to the completion of the test. If it were not for the changes in the international situation, China would need an advanced fighter. Maybe it will extend the test flight test time and delay the time of mass production.

Even for the F22, the entire test process was also very long, and the life, maintenance life and various indicators of the F119 aero engine were even determined based on this.

Therefore, this year's first test flight is not the end. On the contrary, it is a brand new starting point. It also needs to complete a large number of test flights. In the process, it is inevitable that various problems will be encountered, such as problems with aeroengines, such as fighter jets. Problems, such as the problem of anti-G suit, such as avionics system and a series of other problems.
