readx; With the landing of the fighter, the airport was completely cheered, no matter what, this is at least their first domestic fighter, and judging from the data sent back, this fighter has a great advantage over the Hellcat fighter in terms of speed, because it is designed to reach a speed of 800 kilometers per hour. Pen, fun, pavilion www. biquge。 info

It can be said that once this fighter has completed the test and is equipped with troops, then it will be the most advanced fighter in the world at present, in terms of speed, it will be dozens of kilometers faster than the Hellcat, and in terms of armor, the Hellcat is not his opponent.

Of course, in terms of weight and physique, he is also bigger than Hellcat, and the probability of him being attacked will be greater than that of his surname, but are these still problems? Faster speed allows them to quickly escape from enemy pursuits, and thick armor allows them to withstand enemy bullets.

When the fighter plane landed, the scientific researchers hurriedly surrounded it, and then conducted a comprehensive inspection of the fighter to see if there were any security vulnerabilities.

After a busy afternoon, the results of the inspection were quite satisfactory, as expected, all the data of the fighter were still normal, and there were no accidents in the armor outside, and now we are only waiting for the second test the next day.

If the second test is successfully completed, then there will be a busy test of various difficult maneuvers, and when everything is completed, the fighter can basically enter the mass production process.

Anyway, it's okay to go back, Su Daosuo's surname lives here, he wants to see the first domestic fighter successfully pass the test, and after several years of hard work, he finally developed the first fighter, Su Dao's psychological side is still a little excited.

Although he didn't lack anything before, he has been at the forefront of the world, but after all, it is not his real strength, once one day the atlas is suddenly lost or invalid, then Su Daoke is waiting to cry, the atlas is just an auxiliary force to help Su Dao grow up quickly, if you want to really become the world's first, you need your own manufacturing level.

Early the next morning, the test plane had been pushed on the airport runway, and Zhu Dazhang was ready, the engine had been turned on, and he was waiting for the take-off order from the tower.

Today, the range and ascent limits of the fighter will be tested, and at the same time, the cruise speed and cruising altitude of the fighter will be tested by making a stable flight at different altitudes.

Of course, there are no specific requirements for today's test, and the range of the fighter has not been given by scientific researchers, but Zhu Dazhang has the idea of the fuel gauge on the dashboard, and when the fuel gauge drops to half, he will start to return, and then through today's cruising speed at various altitudes, several tests have been carried out repeatedly, and the range and cruising altitude speed have also been tested.

Testing a new fighter is not an easy task, and a month is far from enough, but now they can't wait, as long as there are no problems with the aircraft, it is basically a test flight once a day, with little time to rest.

"Experiment One, ready to take off."

The sound of the tower was heard from inside the headset.

After getting the order, Zhu Dazhang directly accelerated the fighter, which was similar to yesterday's procedure, and the fighter flew up quickly, and then Zhu Dazhang directly pulled the nose of the plane up and rushed into the blue sky in the order of the test.

The first content of today's test is to test the climbing rate and the maximum ceiling, and then slowly test the range, anyway, it is just a back and forth climb, and it doesn't use too much fuel, and all kinds of situations will happen in the battle, they must consume a little fuel before going to the test.

I have to say that the new fighter with a high-power engine is really different, and the climbing speed has reached a terrible 24 meters per second, and the fighter has easily broken through the height of 10,000 meters, and nothing abnormal has happened.

"Report to the tower, Experiment 1 is now at an altitude of 10,000 meters, and the data of the aircraft are normal, please ask for instructions on the next step."

Zhu Dazhang observed for a while at an altitude of 10,000 meters and found that there was nothing abnormal, and after making sure again, he reported the situation to the tower through the communication system.

"Slowly ascend 500 meters, pay attention to the situation of the fighter, if it doesn't work, quickly withdraw it, accompany the hellcat on the trial to observe the outside, and if something is wrong, immediately stop the mission and return home."

The commander in the tower couldn't help but be a little excited, forcibly concealed the excitement in his heart, and continued to command.

After getting the order, Zhu Dazhang also began to slowly continue to pull the nose of the plane up, but this time the speed was not as fast as before, Zhu Dazhang mainly wanted the fighter accompanying the trial flight to observe the flight posture outside.

When the fighter plane flew smoothly to an altitude of 10,500 meters, Zhu Dazhang didn't feel anything abnormal, but felt a little cold, compared to the temperature at 10,000 meters just now, the temperature dropped by at least one or two degrees, but he didn't pay attention to anything, for pilots, this situation is common, even if the temperature of the Hellcat fighter rises in altitude.

After all, the fighters of this era have no air conditioning, and the sealing is not tight, and it is normal for the cold wind to run over, but Zhu Dazhang clearly felt that everything was normal when he was 10,000 meters in the air, and he didn't feel cold, but it was a little cold at 10,000 meters and 500 meters.

"Report to the tower, the experimental equipment No. 1 is normal, and the temperature in the cabin has dropped by about one or two degrees. Request next step instructions. ”

Ten minutes after flying flat at an altitude of 15,000 meters, Zhu Dazhang reported.

In fact, the test pilot has no rights, and when the test flight is all under the command of the ground tower, let the test pilot do whatever he wants, the test pilot only needs to report the real-time situation back, and the command center will give instructions on how to do it.

"Continue to ascend 500 meters, pay attention to the data and temperature, and stop the mission immediately if the temperature drops too fast."

The tower also sent back instructions for the next step.

It is normal for the temperature to drop by one or two degrees, and besides, it is already at an altitude of 10,000 meters, and it is a test flight, and if the test flight is stopped when encountering some difficulties at this time, then there will be greater danger in the future. Besides, one or two degrees is not a big deal, if it is four or five degrees, then the tower will have to stop the test flight, and continue the test flight after solving this problem.

Zhu Dazhang continued to pull the fighter higher, and soon, the fighter plane once again flew at an altitude of 11,000 meters, although all the data were normal, but the temperature still dropped very violently, but it was only about 500 meters at an altitude, and the temperature dropped by two or three degrees.

And now Zhu Dazhang can also feel the cold wind swishing, even if he has a flight suit to keep out the cold, Zhu Dazhang is still a little difficult to adapt, the temperature drops sharply in a short period of time, and it is difficult for anyone to adapt.

"Report to the tower, the data of Experiment No. 1 are normal, the temperature has dropped by about two or three degrees, and wind can be felt at the junction between the cabin cover and the fuselage, which is probably caused by poor sealing."

Zhu Dazhang couldn't help but shudder, and forcibly held back this and reported.

For more than ten minutes, he was motionless, but the temperature dropped again and again, and this change in temperature was still very uncomfortable for the pilot, so he could only sit and let the cold air blow on his body, and he couldn't move or anything.

"Can you still afford it?"

The tower then also came to the nervous sound, and the atmosphere in the tower was more tense than the sound in the radio, this result greatly surprised their expectations, the temperature dropped too fast, and found the ventilation point, if it continues to rise, it is very likely that an accident will occur, even if the fighter can resist, the pilot is difficult to resist.

But at present, only more than 300 meters away from the maximum ceiling of the Hellcat fighter, if the test flight is stopped at this time, it will undoubtedly be a big blow to morale, although the problem has leaked out, but if it can still surpass the Hellcat in the case of problems, or the same as it, then it will be much easier for scientific researchers in the subsequent improvements.

"Yes, but it shouldn't be too long, and I'm feeling a little numb now."

Zhu Dazhang nodded and replied.

"That's good, continue to ascend 300 meters, fly level for three minutes, carefully observe the ventilation point, and return immediately after three minutes."

After deliberation, the tower still decided to continue to rise in altitude, for them, as long as they can rise 300 meters is a success, and find more ventilation points at an altitude of 11,300 meters, then after modification, the maximum altitude of this fighter will be increased by at least a few hundred to a thousand meters.

Soon, Zhu Dazhang also continued to pull the fighter higher, but this time it was a little difficult, of course, this is just compared to the previous climb, compared with the Hellcat fighter, it is still much easier.

And the data on the dashboard are the same as before, very normal. To say that the first fighter developed by the Chinese Empire had such an excellent surname, and it was the second test flight? How is this possible?

Although it sounds a little appalling, please don't forget that before the development of this fighter began, Su Dao handed over the world's most advanced fighters such as the Hellcat fighter and the Panda carrier-based aircraft of Hainan Airlines to the research institute.

Don't dare to say anything else, now the people in the research institute have long known the surnames of these fighters, as if they are as clear as their own research, and this new fighter also combines the advantages of various fighters, and has been replaced with a higher-power engine, as long as there are no major problems, it is not difficult to easily surpass these fighters.

When the fighter plane rose to an altitude of 11,300 meters, Zhu Dazhang first carefully observed the data on the dashboard, and when he found that everything was normal, he put down his snack a little, and then began to focus more on the ventilation point.

Zhu Dazhang took out a marker from the pocket of his clothes and clicked on the ventilation point, there are so many places, if he wants to memorize them one by one, there will inevitably be some mistakes, and carrying a pen with him is also a necessary procedure for test pilots, mainly to record some data or something.

Everything is normal, but the temperature has dropped more than before, the height difference of three hundred meters, the temperature has dropped by three or four degrees again, which makes Zhu Dazhang a little unbearable, and what makes Zhu Dazhang even more depressed is that the cabin cover seems to be unbearable, and there is a faint sense of wanting to collapse.

Seeing this, Zhu Dazhang no longer hesitated, and directly lowered the height of the fighter, and the current situation has exceeded his expectations, and if the problem of the cabin cover is not solved, it will be impossible to break through this limit in the next test flight.

"Report the tower, I am the experimental No. 1, the data of the fighter are normal, but the cabin cover seems to have signs of collapse, I have marked the ventilation point, the fighter is currently descending in altitude, at an altitude of about 10,000 meters, the cabin cover has also returned to normal, and the ventilation point is also much less, basically there is no big impact."

Zhu Dazhang hurriedly reported.

"Experiment One, return immediately, cancel other test flight missions."

The tower immediately commanded. (To be continued.) )
