"Qin Feng, how about it? Do you want to try it?" At this moment, Old Tu said to Qin Feng with a smile.

Hearing this, Qin Feng shook his head quickly: "No, Mr. Tu, I have not participated in the research of this plane and am not very familiar with its various data, so let the original test pilot fly."

The flying of a fighter is of great significance. Although the J-7 in front of us is a modification, it is already the most important modification because it changes the aerodynamic layout of the entire body, and this improvement will surely be recorded in history.

Whoever tests it will leave his name. It is quite meaningful to leave his own mark in the history of the aviation industry exhibition. Qin Feng is busy with many projects now, so he will not get involved in the test flight of this aircraft, and let the original test pilot fly.

Hearing this, Mr. Tu smiled and said, "Why didn't you participate in the research? You started to follow up this aircraft since the project was proposed. After that, you participated countless times and proposed many constructive plans. Especially in the structure of the double-decant wing, the addition of the front-edge maneuver flap of the wing has been considered essential. Let me tell you now, in fact, the test pilot of the flight scheduled for this aircraft is originally you. If you don't have you, others will come on."

Double-delta wings are to form two different angles on the wing and increase the wingspan. This is an important improvement. In the improvement, as the research deepens, Professor Sha has also encountered many problems.

For example, in the blower tunnel, as the aircraft's angle of attack increases, the outer wings of the double-triangle wing will have airflow separation, which will have an adverse impact on the pitch stability of the entire aircraft. In this way, the originally planned performance of the large angle of attack cannot be achieved.

In the previous J-5 and J-6, wing knives were used to hinder the separation of this airflow. However, after analyzing and researching with experts, Professor Sha and his experts believed that adding maneuverable flaps could solve this problem. Its deflection angle can automatically and timely deflect to the required angle as the aircraft's flight state is in flight, so that the problem of airflow separation can be solved.

This is a very complicated task, because the J-7 does not have a fly-by-wire flight control, and the maneuverable flap is automatic and requires a reliable control system. It took them several years to overcome this technical difficulty.

When it comes to the selection of test pilots for the plane, if Qin Feng can come, he is of course the best. Although he doesn't spend time in this project every day, he is definitely very familiar with the use of every technology of the project. He is also very familiar with the flight operations of the third-generation aircraft and is an experienced flying veteran.

After the J-7 e in front of him flew, he would have to transfer to the test flight test institute. In other words, Qin Feng could also continue to test flights such aircraft in the test flight institute, which would not affect his flight of the J-7 and J-8 oil-receiving aircraft. After all, the flight missions cannot be held every day.

This time, since Qin Feng is here, the scheduled test pilot is Qin Feng.

After hearing Mr. Tu’s introduction, Qin Feng finally couldn’t help but feel excited: “Since I have decided to let me go, I’m not polite.”

After saying that, Qin Feng quickly ran to the familiar pilot preparation room, went there to change his flight suit, and was ready to fly!

Everyone looked at his back and his face was filled with smiles. As long as Qin Feng was there, nothing was difficult. He was a person who could create miracles.

Besides, everyone is very confident in their plane.

Qin Feng also felt the confidence of the aircraft designers when he put on various equipment and when he held the flight plan.

If it is a normal flight, it means you can go to the sky and get off after a round trip. However, the J-7e of this aircraft is originally a modification. Moreover, since it is once in the sky, it must reflect its performance. Therefore, this first flight has many flight items.

Qin Feng was very satisfied with the arrangement of this test flight. He was ready and stepped onto the plane with great strides. Then, he saw the familiar instruments in the cockpit, which also had unusual numbers.

Qin Feng has read all the technical information of this aircraft. This aircraft has many new features. Although the appearance has not changed much, it has actually been given a new mission. For example, its wing modification not only improves maneuverability, but also changes the internal structure, and designs an overall wing fuel tank inside the wing!

For an aircraft, the range is related to the amount of fuel it carries in large quantities. The air force of many countries has rigid indicators for the range. For example, the Pakistani Air Force would rather have a machine gun than increase the fuel capacity.

The wings of the J-7e are redesigned, so there is a new solution to make the interior hollow and place the overall fuel tank inside, which can greatly increase the oil carrying capacity of the fighter!

In fact, this is a common method used by many countries. Take the MiG29 as an example. The space inside its body is quite limited, the oil carrying capacity is very small, and most of the fuel is placed in the wings.

Since China has always inherited the design of previous fighter jets, it has not yet made such a wing fuel tank. This is the first time. Just this change, coupled with the external auxiliary fuel tank, can make the J-7 have a maximum range of 2,000 meters, and even the J-8 range, which is also an amazing progress.

Qin Feng sat in the cockpit, suppressed his excitement, and began to prepare for normal takeoff.

After returning from the Soviet Union, I saw many advanced fighter jets from the Soviet Union. No matter how advanced they are, they are theirs. The current fighter jets are domestically produced, low-cost, can be equipped with a large amount of equipment, and there will be no risk of being stuck.

Everyone on the ground stared at the plane, the canopy hood slowly closed, the turbojet-13 motive at the tail was ignited smoothly, Qin Feng operated the plane and slowly slid towards the runway.

The J-7e flight is slowly kicking off. The first domestic model that is highly maneuverable and can fight the F16 fighter jet in close range, spreading its wings and waiting for a surge in the sky.
