Chapter 824 Soaring to the Sky! (Second Update!)

Beside the window of the tower, a group of old men stood on tiptoe with binoculars in their hands, trying to lean out and see the planes flying in the sky clearly.

Then, they were forcibly dragged away by the security department because of their dangerous actions.

In the end, only Fang Jianguo and He Qingyang stayed because of their work and their technical knowledge.

The high-definition camera on the top of the tower took pictures of the planes spiraling in the sky one by one, and then displayed them on the big screen in the middle.

Xian Yufan stood in the middle, holding his chin with his right hand, and kept directing the person who controlled the monitoring:

"Pause this picture, and then enlarge the picture."

"And these pictures too, pause them all, and then enlarge them."

Under the control of the operator, the pictures specified by Xian Yufan were paused, cut into pictures separately, and then enlarged again.

In the end, everyone's eyes were fixed on the position of the aircraft engine.

Under the monitoring of the high-definition camera, it can be vaguely seen that there is a spatial distortion at the position where the tail of the aircraft engine is ejected.

At the same time, the faint blue flame can also be seen.

After staring at the blue flames in several pictures for a while, Xian Yufan nodded with great satisfaction:

"Yes, the performance of the aircraft engine is very good, and the color of the flames ejected is normal, which means that even in non-laboratory conditions, the fuel has been fully burned."

"It just matches the data and theoretical data we tested."

Listening to his explanation, He Qingyang bent down, dragged the mouse himself, enlarged several pictures on the screen, and slid the mouse over the flames ejected from the tail of the engine little by little.

Seeing that he cared so much, Xian Yufan called the person in front of him away, sat down himself, and then used his authority to retrieve the close-range monitoring data of the laboratory.

After searching for a long time in the monitoring data of the laboratory, he finally found a simulation situation similar to the current flight status of the aircraft, and then found the monitoring data at that time.

Same screenshot, and then put the two photos together, one on the left and one on the right.

"Three months ago, we had already built the engine, and after a series of repeated assembly and disassembly."

"After confirming that there were no problems, we started the extreme test two months ago."

"That is, the continuous combustion test. So far, the prototype engine has achieved a 1,000-hour continuous combustion test at 60% to 80% power output."

"The 12 engines on the plane were re-produced after we completed the 400-hour continuous combustion test, based on the calculated data and the initial plan, and then made partial adjustments."

"As of now, the performance of this engine is not bad!"

Xian Yufan said modestly, then turned on the monitoring, continued to watch the plane in the sky, and stopped the screen from time to time, enlarged the screen, and then observed carefully.

When you see something that you feel confused about, write down the timeline and write down the situation you found.

On the No. 01 plane, Yuntian watched the numbers on the instrument panel slowly climb. When the numbers passed 7500, he tapped the headset lightly:

"Tower, this is 01, this is 01, current altitude 7500, about to arrive at 8000, over."

"0101, this is the tower, circle according to the mission book, over!"

"Tower, I want to fly in a straight line! Over!"

"0101! The factory director is on the communication channel, you can call him directly, and then you don't have to fly today, over!"

Conversation between the air traffic control and Yuntian As soon as the words were finished, before Yuntian could react, Lin Yu's gentle and elegant voice sounded in the headset:

"0101, this is Lin Yu, keep circling at 8,000 altitude for 20 minutes, then climb to 9,000 altitude and circle for 20 minutes, finally climb to 10,000 altitude, circle again for 20 minutes. There is no option to fly in a straight line in the morning test. If you dare to fly, you don't have to do it in the afternoon. Over."

On plane No. 01, listening to the voice in the headset, the co-pilot, navigator, and communicator laughed beside them.

Then, the three people turned off the microphone and started to say sarcastic words in Yuntian's ear.

"Captain, we can't bear their anger, return now, and then you get off the plane!"

"Yes, yes, Captain Yun, we can't bear this anger, you go back to the Western Aircraft Manufacturing Bureau!"

"That's right!"

Faced with the words of these three people, Yuntian raised his right hand without hesitation and gave the three people a middle finger.

"You three, get as far away as you can. As long as I am here, I will always be the captain! Don't dream!"

As a member of a flight formation, the captain is the soul of the formation and also the commander.

When the captain is normal, others must obey the captain's orders, unless the order is very outrageous, so outrageous that there is no reason to refuse.

However, if the captain is fired, the co-pilot can replace the captain in the first time, give orders, and then command the mission.

And the navigator and communicator are actually pilots. In special circumstances, they can also replace the captain.

So, Yuntian knows what these three people want to do better than they do.

In the tense and orderly flight, 20 minutes is very fast, almost in the blink of an eye.

When the timer sounded, Yuntian pressed the microphone again:

"Tower, 01 has completed the 20-minute circling mission at an altitude of 8,000 and is now climbing. It will soon reach an altitude of 9,000 for circling. Over."

In the tower, after receiving the report from aircraft 01, the air traffic controller turned his head and looked at Lin Yu beside him: "Director, let aircraft 2 take off?"

Lin Yu did not speak, but just nodded his head lightly.

The air traffic controller received the order and began to command aircraft 2 to take off.

The captain of aircraft 2 was Jiang Ming. After receiving the order to take off, he closed his eyes, took a deep breath, and then turned on all the equipment according to the operation procedures he had practiced countless times before.

When the order from the tower sounded again, he pushed down the throttle without hesitation.

After a short taxiing, aircraft 02 also broke through the sky and flew high into the sky.

After circling in the air for several circles, aircraft 02 also began to spiral climb, but the climbing position was exactly opposite to that of aircraft 01.

So, another white spiral spring appeared in the air, just opposite to the first spiral spring.

After the No. 02 aircraft completed a 20-minute circle at an altitude of 8,000, the No. 3 aircraft also followed the command and broke through the sky.

More than an hour later, all three aircraft appeared at an altitude of 10,000 and continued to circle in the air according to the instructions of the mission book.

So, on this day, everyone in Gaocheng saw the donut in the sky.

The three aircraft had been circling at high altitude. When the circling time was up and the fuel of the aircraft was almost consumed, the No. 01 aircraft was the first to lower its altitude and speed. After circling in the air for several circles, it aimed its nose at the runway.

The distance between the aircraft and the runway was shortened. Tomorrow, the angle was adjusted again, and the nose of the aircraft was aimed at the central axis of the runway. The right hand slowly pulled the throttle lever back to reduce the speed of the aircraft to the speed that could land. Then, the nose of the aircraft slowly tilted downward.

His heart slowly hung up with the tilt of the aircraft head.

It is a skill for an aircraft to fly into the sky.

And it is even more of a skill for an aircraft to land.

There are many aircraft that are very stable when taking off, but there are problems when landing.

Now, it is time to check the fuselage structure, landing gear structure strength, and aircraft tire structure strength.

The altitude is getting lower and lower.

Finally, everyone on the plane felt a slight vibration.

That was the vibration caused by the front landing gear of the aircraft colliding with the ground.

Almost at the moment when the vibration came, Yuntian shouted:

"Report data!"

"The front landing gear hydraulic sensor is normal, the rear landing gear hydraulic sensor is normal, the engine oil output is the same as the preset setting, and the speed has been reduced! The rest of the equipment is working normally..."

The co-pilot blurted out the data he needed to report at the fastest speed.

Hearing that they were normal, Yuntian couldn't help but breathe a sigh of relief, and his right hand also moved away from the throttle lever that disconnected the power output and moved to the brake.

The brake lever was slowly pulled, and the brake lever pulled the brake device, which started to work and pushed the hydraulic screw on the landing gear. The hydraulic screw began to limit and slowly stuck the forward wheels.

A correct version in 16-9 book and bar!

The plane stopped completely, and then the first person to appear on the runway was none other than Xian Yufan, who was driving a tractor.

Behind him was the ferry of the mechanical repair team. The mechanical team skillfully hooked the chain on the tractor to the plane, commanded the tractor to start, and towed the plane into the hangar.

A group of people first dragged the gangway to pull the four people in the plane down, and then got into the plane like wolves and tigers, connected the main engine with special equipment, and began to check the flight data this time, and at the same time tested whether the sensors in various positions were working properly.

The people in the mechanical repair team were like wolves and tigers, and the people in the medical team were even more so.

One by one, the burly doctors came forward, forcibly held Yuntian and the other four, dragged them to the bed, held various instruments and equipment against their chests, clamped their fingers, and drew blood.

The doctor in charge was not tired of stretching out one finger after another in front of them: "What is this?"

The doctors in the medical team tossed them around, and then threw them to the impatient design team next to them who had been waiting for a long time.

The design team held notes and previously prepared investigation reports in their hands. They formed groups of three or four and surrounded Yuntian and his companions, and began to ask all kinds of questions.

"What do you think of this flight helmet?"

"Do you think this instrument panel is easy to use?"

"What do you think of these joysticks?"

"What do you think of the viewing angle of this aircraft, or the field of vision, from your position?"

"What do you think of the seats of the aircraft?"

"How do you feel wearing that flight suit?"

"Do you want to adjust the oxygen concentration?"

"Do you want to add a small refrigerator to the aircraft?"

After several dozen minutes, the flight time of aircraft No. 2 was also up, and it returned to the ground under the same operating procedures.

Before the pilot on the plane could show off, he was also forcibly pulled out by the repair team, and then handed over to the medical team. After the medical team finished their work, they handed it over to the design team.

When aircraft No. 3 landed, the pilots on aircraft No. 1 and No. 2 took the initiative to help and took the initiative to pull out the people in aircraft No. 3.

At 1:17 p.m., the data of the three aircraft were read. After getting the raw data, Xian Yufan did not dare to neglect it and went to the tower as soon as possible.

In the independent conference room of the tower, he showed these data in front of Lin Yu.

"The aircraft power system is very stable, very stable, even in the process of rapid climb, it is very stable."

"Then there is the temperature system of the aircraft. According to the temperature sensors installed in various corners, when hovering at an altitude of 10,000 meters, the lowest temperature is the bomb bay."

"As for the most important cockpit, the temperature has been maintained at a suitable 24 degrees, without change..."

"At the moment the plane landed, the data recorded on the landing gear sensor did not reach 20% of our expected design."

"At this point, I think we should be proud because our own materials have temporarily passed our test."

"This time It is the result of the test without any heavy objects, and it is also the result of the test under the premise of consuming enough fuel. The data of the subsequent full-load test may be different. "

"Finally, it is the pilot's opinion. They said that the helmet is boring to wear and it feels like it blocks their vision."

"As for the clothes, they think they are not bad, but they don't fit well..."

After Xian Yufan finished his report, Lin Yu didn't speak, but raised his right hand and looked at the time on the watch:

"Arrange everyone to eat as soon as possible, take a rest after eating, and start the second round of tests at 3 pm."

The second round of tests will start at 3 pm today, and Xian Yufan is very excited.

Because in the task book, the second round of tests is cruise tests.

This Tu-160 modification inherits the characteristics of the original Tu-160 and has also undergone localized enhanced transformation.

The cruise speed is extremely fast, and it can also maintain supersonic cruise.

In other words, the afternoon test is the real test.

The time to truly test the terrifying penetration speed of this aircraft!

According to the original plan, the second round of tests should be held tomorrow or the day after tomorrow.

But now, the factory director has brought forward the test.

He wants to tell the pilots this good news to make them excited.

After Xian Yufan left, Lin Yu collected the information he gave him, turned around and walked out of the conference room, and met He Qingyang's people in another conference room.

As soon as they met, he handed over all the information in his hand.

This time, in addition to himself, they also brought a professional team.

As soon as these materials came to He Qingyang's hands, he just glanced at them casually and handed them to the professional team next to him.

A few minutes later, the head of the professional team raised his head, and his pair of black eyes were full of exploration, curiosity, doubt, and fear.

After a moment of stunned, these eyes with countless emotions fell on Lin Yu.

The eyes blinked for a long time, and the owner of the eyes spoke in a hoarse voice:

"Mr. Lin, is your company really taking a plane for the first time?"

"I know my question is very presumptuous."

"But I really want to know, this is the first time you build an airplane, and in such a short time, why can you build such a high degree of completion?"
