"Tower, tower, plane is normal, apply to take off."

"You can take off, good luck."

"Understood, good luck."

On the outskirts of Shengjing, two silver warhawks were preparing for the take-off of the plane on a relatively hidden and relatively small airfield. On the observation deck in the distance, more than a dozen technicians were holding binoculars to observe the two planes, strictly speaking, they were observing the second plane.

According to the experimental regulations, the aircraft test flight, must have a companion aircraft, the accompanying flight of this war eagle for the original Mao Xiong imported aircraft, it is mainly responsible for tracking, taking pictures, reporting the flight status, No. 2 aircraft is Jiang Yan They through the restoration of the Mao Xiong country's drawings, in accordance with the technical requirements of their drawings to manufacture the aircraft.

Due to the need for secrecy, there were not many people who came to visit, only a dozen people, but these people were quite weighty people.

The pilot on the second plane, after hearing the command of the tower, stepped on the accelerator and the plane began to taxi.

"Glide smoothly." Mr. Xu, who was holding a telescope, spoke.

"Nervous?" Mr. Xu saw that the plane had taken off, and asked Jiang Yan next to him.

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

In the early days of fighters, the flight test process was relatively simple, often composed of designers, test pilots, and test flight engineers. At that time, a new aircraft only needed more than 10 rounds of test flights to be finalized and put into production.

Modern fighters have a complex structure, including dozens of subsystems and tens of thousands of parts.

In order to integrate such a complex and large system and components, but also to ensure safety and reliability, the requirements and difficulties of test flights are far more difficult than before. In the flight test process of modern fighters, the test flight engineer usually determines the test flight appraisal plan first, and after approval by the relevant aviation agencies, the test flight engineer forms a flight test outline according to the appraisal plan, and assigns the test flight task to the research group for implementation.

However, since the Zhan-6 aircraft is an imitation aircraft, it only needs to fly out of the state of the aircraft, which is not the same as the first flight.

"This time, we have invited the best test pilot in the country, and he will definitely be able to fly the best performance of the aircraft." Jiang Yan listened to this sentence, this Mr. Xu seemed to be telling Jiang Yan, and he seemed to be telling himself.

Looking at his eager eyes, Jiang Yan nodded emphatically.

The war eagle roared, and the two of them stopped talking, holding binoculars to observe the current flight status of the plane, and the person in charge of recording next to them observed and recorded. It wasn't until the plane was far away that Mr. Xu put down the plane.

"If you have a cigarette, bring me one." Mr. Xu, who put down the binoculars, said directly to Jiang Yan.

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

After smoking a cigarette, he directly pulled Jiang Yan and came to the tower.

"Push the envelope." As soon as I came to the tower, I heard the order from the tower, and I didn't dare to come out when I heard this Mr. Xu and Jiang Yan.

One by one, the original flight plan was spoken out by the tower commander, and the distant planes completed one subject after another under the command of the tower.

Jiang Yan's heart is also like a roller coaster, quite nervous, and their ears are always listening to the sound in the headset, for fear that something will go wrong.

When all the preset subjects are completed, Jiang Yan can see that Mr. Xu's demeanor is relaxed, but where will Jiang Yan find that his palms are all sweat at this time.

"Tower, tower, scheduled subjects have been demonstrated, please return."

"You can return to the ship, pay attention to your posture."

Hearing that the plane was coming back, Mr. Xu said hello to the tower commander, pulled Jiang Yan and got off the tower, and after about half an hour, the two planes that went away flew back to the airport.

"It's back. It's back. Mr. Xu took Jiang Yan's hand, his expression was quite excited, Jiang Yan broke free without leaving a trace, and he couldn't see that a researcher like Mr. Xu was still so strong.

"How?" As soon as the plane stopped, Mr. Xu rushed over, Jiang Yan couldn't pull it, and when he saw the pilot who had just gotten off the plane, he hurriedly asked.

"Everything is normal, it feels no different from the hairy bear plane I flew before." The pilot was equally happy to Jiang Yan and they spoke.

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

"Yes, we succeeded." Jiang Yan also replied.

"We succeeded." Mr. Xu cheered loudly at 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 letting go of Mr. Xu's breakup, he took Jiang Yan's hand to express his gratitude.

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

"The next step is to improve the aircraft, and hopefully we can take it to the next level." Walking on the road, Mr. Xu said to Jiang Yan.

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

As an early jet fighter, the engine design of the Battle-6 itself was very problematic. In pursuit of maneuverability and speed, fuel consumption can only be increased. The loss of fuel consumption also meant a shorter range, which was almost a third shorter than the range of the Eagle Sauce aircraft at the same time, which also led to the notoriously short legs of this aircraft for a long time.

"Yes, when the time comes, let's hold a meeting together, and then let's discuss, if you have any good ideas for the engine, you can put forward them together."

These two months of working together, Mr. Xu is very good to Jiang Yan, although his theory is not so solid, but this vision is quite broad, his whimsical ideas for the previous imitation work to help that is quite a lot, when he proposed the engine, Mr. Xu knew that this guy should have a study of the engine, and have some whimsical methods.

"There are some immature ideas, let's discuss them when the time comes." Jiang Yan nodded in agreement.

"Okay, I'll organize a meeting when the time comes, and when the time comes, you can talk about your ideas, let's discuss it together, as long as it's a favorable idea, I will definitely support it."

Hearing Jiang Yan say this, Mr. Xu was even more interested, but he also knew that now was not the time to talk about this, so after he agreed, he didn't say anything.

In the history of the development of aviation, there are two ways in the development of aircraft engines, one is the research of the core aircraft of European and American countries, and the other is the model of one fighter plane and one engine like the woolly bear country.

Both of these developments have their own advantages, and it can be said that each has its own advantages. Jiang Yan can't tell if it's good or bad.

However, Jiang Yan feels that the idea of the core machine is more in line with the current national environment, we are not like the woolly bear country with deep pockets, a series of aircraft to study an engine, such a waste of energy and a lot of money, not to mention, the key is that we do not have as many researchers as them.

It is difficult for a good woman to cook without rice.

In the world before Jiang Yan, the country was completely in accordance with their ideas, but then combined with some things from the West, they came out of their own way, but now we still learn from them, but there can be a little change in the middle that is more in line with the national conditions.
