Qin Xue and Gu Tingting didn't have many opportunities to meet, and the longest time they spent together was their mother's illness, but now, after seeing Gu Tingting, they were quite excited and excited, just like seeing an old friend.

"Sister-in-law, it's cold outside, hurry back." Qin Xue took Gu Tingting's hand, and the two walked inside, and Qin Feng became an outsider.

After entering the room, Qin Xue opened her suitcase, and there were actually a lot of children's clothes in this big suitcase!

"It's all made by my mother, I heard that my sister-in-law was pregnant, so my mother started to do it, brother, when we were young, we didn't have this condition, my mother bought new cloth from the town, washed it cleanly, and sewed it out, saying that people in the city pay attention to cleanliness."

The clothes are not big, they look like rag dolls, the stitches on them are very dense, Gu Tingting knows that Qin Feng's old family does not have a sewing machine, it is one of the four major pieces for young people to get married, and now, these clothes are made by Qin Feng's mother stitch by stitch, and they look very good.

"Mom said that her legs and feet were inconvenient, so she couldn't come, and it just so happened that I was on winter vacation, and I was here, accompanying my sister-in-law, and I could also let my sister-in-law tutor me in my homework." Qin Xue and Qin Feng said.

Before Qin Feng could answer, Gu Tingting replied: "That's just right, anyway, our project team won't let me go for the time being, I'm okay here, let's review our homework, seeing that you are going to take the university entrance examination, you have to come on, you can't delay." ”

Inside the room, it was warm.

Qin Feng is relieved now, with his sister coming, he can put down all his burdens and continue to devote himself to the test flight mission.

The eight-gauge bomb hit the target.

There were many experts who came, and in addition to a special target shooting team set up by the test flight institute, there were also comrades from Luoyang, who were personnel of the manufacturing plant for the No. 8 bomb, and at the same time, there were also Israeli experts, and Richard, an engineer with a big beard, was in charge of them.

Now, everyone is making intense preparations.

"Your J-7 already has a pylons for launching Sidewinder missiles, and this pylons can be hung directly, well, this aircraft looks pretty good." Richard said.

Because the test flight is still in the process of being carried out intensively, the J-7 fighter with improved avionics has not been brought over, and now it is the J-7B that is being used for testing, which is the primary model of the fighter exported to Jordan, and it has been replaced with pylons, and has the ability to hang Sidewinder missiles, and can also hang No. 8 bombs.

Richard circled the plane, circled twice, and said, "Let's try it first." ”

The target of the fighter is divided into many kinds, in China, the common is the cannon target, this even Qin Feng has practiced, specifically, there is a fighter in front, dragging a target, and then, the fighter behind comes up, attacking the target in turn, in this process, the fighter in front is dangerous, in case of who aims inaccurately, may hit the tractor in front.

As far as China is concerned, the main training of the Air Force is to fight machine guns, and there are very few people who have shot missiles, and later, because this method is too dangerous, the task of developing an unmanned target aircraft appeared.

In addition to the needs of fighter planes of the Air Force, ground-to-air missiles also need target aircraft. This was a conundrum for that generation of aviation people.

Later, the country began a long period of self-development, and on December 6, 1966, the "Changkong No. 1" unmanned target aircraft made its first successful flight. From this day on, China has its own unmanned target aircraft.

Although this unmanned target aircraft was modeled after the Soviets' La-17 unmanned target aircraft, however, improvements were quickly made.

There are no changes in the shape, with a typical high-subsonic layout, a slender fuselage with streamlined lines, straight wings, and a large aspect ratio. The horizontal tail is rectangular in shape and is mounted in the middle of the vertical tail. The front and rear sections of the fuselage are aluminum alloy semi-monocoque structures. The engine and its air intake were housed in a pod in the lower part of the fuselage.

The main improvement is its engine, which uses a WP-6 turbojet engine, yes, this is the engine used by the J-6, with a rated static thrust of 21.1 kN at sea level and a maximum static thrust of 24.5 kN, which is many times the original power!

This large, jet, radio-controlled, high-subsonic aircraft can be used for missile targeting or air defense training. It solved the urgent need at once and became the only target aircraft of the Air Force for many years.

Later, with the retirement of the domestically produced Jian-5, in order to turn waste into treasure, the Air Force used the retired Jian-5B medium-altitude target aircraft improved from 1978 to 1984. On the basis of the Target-5B, it has developed into various types of target aircraft such as low-altitude, medium-mobility, electronic jamming, and radar enhancement, and formed a series of various performance of the Target-5B.

However, these target aircraft have a big drawback, Changkong-1 adopts a typical high-subsonic layout, which is slow and cannot simulate high-speed targets; The structure of the airframe is small, and the engine occupies the main space below, so it is impossible to install more equipment, so it is very single-purpose.

For example, now, the No. 8 bomb is to hit a high-speed and high-maneuver target, and such target characteristics are definitely not something that our current target aircraft can simulate, and if you use the current target aircraft to do it, it is meaningless at all, it is to fight bombers, not high-performance fighters.

It can only be imported, and if it is imported, it will require tens of millions of yuan of capital investment, and now, this plan is underway, but the No. 8 bomb can not wait too long.

Now, let's try it first and see if the J-7 missile works, and then shoot the missile first.

"Yes, let's try it today, Lao Zhao, you come first." General Lin was in high spirits and said to an old pilot of the Air Force.

Although Qin Feng was called over, Qin Feng has no experience in fighting missiles after all, and this pilot named Lao Zhao is the pilot who fights the most missiles in the Air Force, the Air Force's Thunderbolt-2 and Thunderbolt-7, he has fought them all, and now he has played this kind of No. 8 bomb, of course, he will hand it over to him first.

Lao Zhao took the flight helmet and got on the plane, and in the eyes of everyone, the fighter flew into the sky.

The rest of the people, full of interest, all came to the flight test control room, where the latest French flight test system was introduced, quite modern, when Qin Feng went to France, he saw the real-time display of the lenses of the other party's cameras, and the real-time transmission of those indicators, here, have been realized.

The state also spent a lot of effort in the test flight institute.

"It has reached the designated airspace and is ready to launch missiles." Lao Zhao shouted.

"Roger, you can start, pay attention to the launch steps." Said the command staff.
