Siheyuan starts from a better life

Chapter 495, next plan

"Tower, tower, the plane is normal, please apply for takeoff."

"You can take off, good luck."

"Understood, good luck."

On the outskirts of Shengjing, at a relatively hidden and small airport, two silver war eagles were making preparations for takeoff.On the observation deck in the distance, a dozen technicians were observing the two aircraft with telescopes. Strictly speaking, they were observing the No. [-] aircraft.

According to the experimental regulations, the test flight of the aircraft must be accompanied by an accompanying aircraft. The War Eagle accompanying the flight is an original aircraft imported from Mao Xiong. It is mainly responsible for tracking, taking photos, and reporting flight status. The No. 2 aircraft is Jiang Yan and they passed the investigation of Mao Xiong. The restoration of Xiong Guo's drawings, and the aircraft manufactured according to the technical requirements of their drawings.

Due to the need for confidentiality, not many people came to visit, only a dozen or so people, but these few people were quite important people.

The pilot on Plane No. [-], after hearing the tower's instructions, pressed the gas pedal and the plane began to taxi.

"Gliding smoothly." Mr. Xu said, holding a telescope.

"Are you nervous?" Mr. Xu asked Jiang Yan next to him when he saw that the plane had taken off.

Hearing Mr. Xu's question, Jiang Yan smiled bitterly and said, "Of course I'm nervous. My palms are all sweaty."

For early fighter aircraft, the flight test process was relatively simple and often consisted of designers, test pilots, and flight test engineers. The entire test flight process was completely based on "following your feelings," and the test flight results were very unsubstantiated.At that time, a new aircraft only needed more than 10 rounds of test flights before it could be finalized and put into production.

Modern fighter aircraft have complex structures, including dozens of subsystems and tens of thousands of parts.

In order to integrate such a complex and huge system and components and ensure safety and reliability, the requirements and difficulty of test flight are far higher than before.The flight test process of modern fighter aircraft usually starts with the flight test engineer determining the flight test qualification plan. After approval by the relevant aviation agency, the flight test engineer then forms a flight test outline based on the qualification plan and assigns the flight test tasks to the research team for implementation.

However, since the Zhan-6 aircraft is a replica aircraft, it only needs to be flown out in the state of the aircraft, which is not the same as the first flight.

"We have hired the best test pilot in the country this time. He will definitely be able to fly the aircraft with the best performance." Listening to this sentence, Jiang Yan felt that Mr. Xu seemed to be telling Jiang Yan, but also seemed to be telling himself.

Looking at his eager eyes, Jiang Yan nodded seriously.

The war eagle roared, and the two of them stopped talking. They used binoculars to observe the current flight status of the aircraft. The person responsible for recording next to them observed and recorded.It wasn't until the plane went away that Mr. Xu put down the plane.

"Do you have any cigarettes? Give me one." Mr. Xu put down the telescope and said directly to Jiang Yan.

Mr. Xu usually wants to smoke, that is, he only smokes one or two when he is thinking about problems or when he is nervous. He took the initiative to ask for a cigarette. It can be seen that Mr. Xu is quite nervous now.

After smoking a cigarette, he took Jiang Yan directly to the tower.

"Perform extreme improvement." As soon as they arrived at the tower, they heard the order coming from the tower. Both Mr. Xu and Jiang Yan did not dare to express their anger when they heard this.

The original flight plans were spoken one by one in the mouth of the tower commander, and the distant aircraft completed one subject after another under the command of the tower.

Jiang Yan and the others felt like they were on a roller coaster. They were quite nervous. Their ears were always listening to the sound in the headsets, for fear that something would go wrong.

When all the preset subjects were completed, Jiang Yan could see that Mr. Xu's expression was one of relaxation, but Jiang Yan would have noticed that his palms were all covered in sweat at this time.

"Tower, tower, the scheduled demonstration has been completed, please return."

"You can return, please keep your attitude." After hearing that the plane was coming back, Mr. Xu said hello to the tower commander, then took Jiang Yan and got off the tower. After about half an hour, the two planes departed. The plane flew back to the airport.

"Back. Back." Mr. Xu held Jiang Yan's hand with a very excited expression. Jiang Yan broke free without leaving any trace. It was hard to tell that a researcher like Mr. Xu still had such strong hands.

"How's it going?" As soon as the plane stopped, Mr. Xu rushed over. Jiang Yan couldn't hold him back. When he saw the pilot who had just got off the plane, he quickly asked.

"Everything is normal. It feels no different from the Bear Country plane I flew before." The pilot said to Jiang Yan and the others happily.

"Then we succeeded." Mr. Xu looked at Jiang Yan and said.

"Yes, we succeeded." Jiang Yan replied in the same way.

"We succeeded." Mr. Xu cheered loudly to the others.

The officer in charge of the flight command came to Mr. Xu and took Mr. Xu's hand.

"Mr. Xu, thank you!" After putting Mr. Xu down and saying goodbye, he took Jiang Yan's hand to express his gratitude.

At this time, the entire experimental platform became a sea of ​​joy, and everyone was smiling.

"Our next step is to improve the aircraft. We hope to take it to a higher level." Mr. Xu said to Jiang Yan while walking on the road.

"I think when we improve the aircraft, we also need to inform the engine factory to see if the engine can be improved at the same time."

As an early jet fighter, the Zhan-6 has huge problems with its engine design.In order to pursue maneuverability and speed, it can only increase fuel consumption.The loss of fuel consumption also means that the flight range is shortened. Its flight range is almost one-third shorter than that of Yingjiang's aircraft at the same time. This has also resulted in this aircraft being famous for its short legs for a long time.

"Okay, let's coordinate it when the time comes. We'll hold a meeting together. We'll discuss it then. If you have any good ideas about the engine, you can put them forward."

In the past two months of working together, Mr. Xu has been very kind to Jiang Yan. Although his theory is not that solid, his vision is quite broad, and his fantastic ideas have been of great help to the previous imitation work. When he brought up the engine, Mr. Xu knew that this guy should have researched the engine and had some fantastic ideas.

"I have some immature ideas. Let's discuss it when the time comes." Jiang Yan nodded in agreement.

"Okay, I will organize the meeting when the time comes. When the time comes, you can tell me your ideas and we will discuss it together. As long as it is a beneficial idea, I will definitely support it."

Hearing what Jiang Yan said, Mr. Xu became even more interested, but he also knew that now was not the time to talk about this, so he agreed and remained silent.

In the history of the development of aviation, there are two paths in the development of aircraft engines. One is the research of core aircraft in European and American countries, and the other is a model of one fighter jet and one engine like the Mao Xiong Country.

Each of these two developments has its own benefits, and it can be said that each has its own merits.Jiang Yan couldn't tell whether it was good or bad.

However, Jiang Yan feels that the idea of ​​​​core aircraft is more in line with the current national environment. We are not as wealthy as the Bear Country. Researching one engine for a series of aircraft consumes energy and a lot of money. The key is that we do not have as many as they do. researchers.

It's hard for a clever woman to make a meal without rice.

In the world before Jiang Yan, the country followed their ideas completely, but then it combined some Western things and found its own way. But now we still mainly follow them, but there may be something in between that is more consistent. changes in national conditions.
