"Yes, everyone cheer up, we have at least verified that cleaning up alone is not enough, it is not thorough, we have to find a new plan!" Song Lao also stood up, he knew that he couldn't give up, he was the chief engineer of the entire aircraft, if he was discouraged, what about others? Will anyone else be able to hold on?

This small blow will not make Song Lao depressed, after a short period of pain, it is new research, scientific research, where can it not fail?

In fact, it is not only the blow and pressure that makes everyone depressed, but the main thing is guilt, you know, an engine costs a lot, even if it is just sent back for overhaul, it is also a waste of valuable wealth, the allocation of J-10 is not much, if it is not for the export of J-7 to make money, this project will not be able to do it at all, now, they have not yet flown up, just a test run, it broke two engines, and there are more guilty elements in my heart.

However, whether it is guilt or blow, in short, stand up and continue to solve the problem!

It's said to have been cleaned up, so what's the problem?

Qin Feng came down, stood on the ladder, and also looked inside, this is a rectangular air intake, the more inward, the larger the space, and finally all unfolded, the area is as large as the fan blades of the engine, this is an irregular structure, it is not easy to process, so when processing, there will be a lot of metal residue, and the last cleaning is said to have been in place.

He shone a flashlight, looked at the cracks in the metal structure inside, and suddenly said to Song Lao: "Song Lao, if we can't clean it up, then how about we plug these gaps?" ”

When the engine is working at full power, the attraction is great, and some fine metal chips inside the gaps, or even the metal edges, you know, even if there are only a few tenths of a millimeter of metal chips, under the adsorption of high-speed airflow, a lot of momentum will be generated, although the mass is small, but the speed is large!

In this way, if you hit the fan blades of the engine, the edges of the blades are very thin, and the blades may be smashed.

Continue to clean it again, and after cleaning, block all the gaps that may lead to the air intake! When it's all blocked, even if there are small crumbs that have slipped through the net, you can't get in.

"yes, if it can't be cleaned up, let's just block it!" Song Lao nodded: "Now, let's do it, let's clean it up again, and after cleaning it up, block it!" ”

As long as you think about it, there is always a way, and there are always more ways than difficulties! Human wisdom is endless, and difficulties are limited!

Keep coming!

The second test failed again, but also attracted the attention of the superiors, in an instant, there are a lot of leaders are paying attention, the on-site technicians are under pressure, everyone turns the pressure into power, day and night, and after half a month, finally, according to the new plan, the cleaning and blocking operations were completed.

The ground was cleaned up, and even the outside of the plane was surrounded by a circle of red ropes, which had nothing to do with people and could not enter! Save something that someone is carrying from falling to the ground and being sucked into the engine.

"General Lin!" Before the test drive, Qin Feng saw the familiar figure again, although General Lin was busy with work, but, every few days, he would come here to go around, General Lin's arrival was an encouragement and a spur to everyone.

"Well, I'll take a look." General Lin said: "Everyone is waiting for our good news! ”

"Don't worry, it's going to be okay this time." Qin Feng said, his leather shoes were polished brightly, and the soles of his shoes were also clean, and after he climbed onto the plane, the gangway was moved, the ground was dragged again, and the third test ride officially began!

When the roar of the engine ended, Xiao Liu was the first to run to the air intake, climbed in along the ladder, and checked for a long time.

Everyone's hearts are inexplicably nervous again, shouldn't there be any problems?

When Xiao Liu came out of it, his face was full of joy: "After my repeated inspections, our fan blades are intact without any damage, and the problem of excess in the air intake tract being sucked into the engine has been solved!" ”

"Great!" Hearing this, Qin Feng shouted happily, he didn't get down from the plane just now, and now, he climbed out of the cabin, stepped on the canard wings, jumped onto the main wing, and then jumped directly from the edge of the main wing.

At this time, everyone found that they only cared about checking the air intake, and actually forgot to move the gangway for the pilot, and Qin Feng also created a new route, if there was no gangway, how could the pilot get off the plane?

The tomcat is the most convenient, because the side of the tomcat's fuselage has made a few concaves, and after flipping, it is a step, which is very convenient to climb up, and the body of the J-10 is originally small, so there is no need to design this device, and it is very particular about climbing down.

The position of the cockpit is too high, it will definitely not work to go down directly, the pilot's body is precious, even if it is twisted, it will not be able to fly for a long time, the loss is too great, go backwards, step on the canard wing to the main wing, and the height of the main wing will be appropriate.

Of course, you don't have to worry about stepping on the canard wings, that thing can be used at supersonic speeds, the pressure is very high, and it is impossible to break it after a few steps, then it is not an airplane, but a model.

Elder Song let out a long breath.

Since the first time this failure occurred, Song Lao's heart has a heavy pressure, after the last failure, this pressure has reached its peak, although Song Lao did not show it, still with everyone to analyze the reason, together to find a solution, but in fact, the pressure in his heart is the greatest, especially now, the air force to Su-27 not to J-10 is getting louder and louder, this plane, any problems, may be amplified.

Now, this problem has finally been solved, and a big stone in my heart has finally landed.

"Great, I know that everyone can solve the problem, I don't know when this plane will be able to fly?" General Lin asked.

General Lin is also very anxious, he is quite concerned about this plane, and now, hearing General Lin's question, Song Lao said firmly: "We strive to achieve the first flight of this plane by the end of this year!" ”

It's summer, and there's still half a year to go, so it should be okay to use this half year to complete the airplane's taxiing test and then prepare for its first flight, right?

At this time, everyone present was full of confidence, and they didn't know that there were countless questions waiting for everyone behind.

Jian-10 is like being pregnant for ten months and about to be born, but the process of giving birth is also so long, and the road of scientific research is full of twists and turns, but it will not stop everyone's footsteps, in order to release this fighter, overcome obstacles and face difficulties.
