The next day, it was still a good weather for flying, and you could see the white clouds in the clear blue sky, Qin Feng and Tang Gang, wearing a full set of flight equipment and carrying flight helmets, walked towards the plane.

Who has ever seen such a situation? Test pilots who undertake test flight missions actually need someone to accompany them to fly?

Tang Gang's heart was grateful, the test flight looked very simple, half an hour in the sky, but he actually had to prepare for a whole day when he came down, Qin Feng flew with him, in fact, it was a waste.

However, Qin Feng didn't care.

"Our plane is originally a two-seater, if only one person has been flying, it is imperfect, in case there is a failure that can occur only two people, we will not be able to find out." Qin Feng was in front of the plane and said to Donald.

Other people's faces are actually filled with disbelief, what is the situation? If two people are in the sky, they can have a breakdown, and when they are alone, they will be fine? Where is it so evil, bringing one more person is equivalent to bringing more fuel, where can there be such a thing?

However, when Qin Feng said this, no one dared to refute it, who is Qin Feng, he is a technical expert, Qin Feng has flown so many models, and he can scare people to death when he says it.

Both of them climbed down the gangway into the cockpit, and after Tang just entered the cockpit, he was suddenly surprised to find that his sense of tension was gone.

Because of his back, there was a feeling that made him warm, with Qin Feng behind him, what was he afraid of?

Up to now, there is still no complete test pilot process in China, there is no special test pilot school, the top pilots in the air force are pulled by the troops, Tang Gang is like this, he was sent out not long after he flew, so Qin Feng is also obliged, there are too few natural ace pilots, many of them need to be tempered the day after tomorrow, and it is necessary for him to help new comrades grow rapidly.

Besides, Tang Gang is the hardest Qin Feng has ever seen, many times, even more than Qin Feng himself back then, the flight theory is extremely solid, and now the study of Jianjiao Qi is also quite thorough, just take out a part, he can tell which part of the plane is used, what is it for, if there is a problem, what will be the consequences, and it is clear, as long as it takes a period of time, he will definitely be able to grow up quickly and become an excellent test pilot of the motherland.

Helping new comrades grow up is Qin Feng's unshirkable responsibility.

Now, Qin Feng is sitting in the cockpit, just like Jiang Taigong, quite leisurely.

As a training aircraft, the front and rear equipment are the same, the instrument layout, etc., are exactly the same, and they can be exchanged at any time, however, because the vision behind is blocked, there is a periscope above Qin Feng's head.

That's right, after Tang Gang in front opened the electric door, a set of folding devices in front of Qin Feng began to slowly unfold.

Speaking of periscopes, they are first used on submarines, which use the refraction of the light path to refract the light overhead.

And its role, to get over obstacles and see things that you can't see, is also very suitable for the current training aircraft.

On the trainer aircraft, the Mikoyan Design Bureau used quite a lot of periscopes, however, this was not created by them, the first to put the periscope on the jet fighter was the Swedish Saab company, they installed a periscope in front of the rear cockpit of the Saab 35 fighter trainer to improve the vision of the rear seat instructor, but this periscope is definitely a direct take-it-or-leave-it, just an ordinary raised telescope.

This is the best way to avoid modifying the design, it is enough to expand the cockpit directly in the back, because there is no increase in the area facing the front, so it will not increase the air resistance, so the Soviets quickly took it and applied it.

However, the Mikoyan Design Bureau still used its brains, they designed it more ingeniously, this periscope is definitely not to be seen by sticking to the eyepiece, but directly two large lenses, which look like a 9-inch metallurgical display.

A lens on the outside and a lens on the inside, all folded up, usually flying, folded well, and in the take-off and landing stage, it is put down, in order to be more concise, they are also designed with the landing gear as a linkage type, the landing gear is lowered, and the periscope is raised; When the landing gear is retracted, the periscope is also retracted, which saves people from having to operate.

Because it's a large lens, it looks like it's the monitor of the Mirage 2000.

The Soviets were the most fond of solving problems in simple ways, they would not go into a complicated TV system, just use these two lenses, and solve it.

As the lenses were unfolded, Qin Feng saw the runway in front of him, and it can be said that the vision was still good.

At the same time, there is also a peculiar phenomenon, Qin Feng can see the outside from here, and at the same time, if he is standing in front of the nose of their plane, he can see the reflection of Qin Feng's head in the lens that rises from the top of the cockpit, he is wearing a helmet, and the oxygen mask also covers most of his face, and he can only see the relaxation in his eyes.

Qin Feng in the back, did not interfere in any way, as long as he sat here, it was already an encouragement to Tang Gang, Tang Gang calmed down, according to the operating procedures, opened the various electric doors, started the engine, when the rear turbojet-7 came from the familiar roar, Tang Gang let out a long breath, now, start to slide away!

In Qin Feng's eyes, he could see the runway on the lenses, the speed was getting faster and faster, faster and faster, and then, the runway was gradually sinking, Qin Feng knew that this was a fighter plane that had already flew.

After the fighter took off, Tang Gang began to retract the landing gear, and the front lenses were slowly folded, and finally all of them were buckled to the top of the cockpit canopy, where part of it was blocked, but for the rear seat, this point of sight blocking was completely bearable.

Qin Feng looked at the blue sky and white clouds outside, and suddenly thought, this seems to be the first time he has been so leisurely, right? Yourself as a passenger, ahead of you is a taxi driver?

There was a noise from inside the headset, Tang Gang continued to call below, and began to fly towards the airspace of the test flight.

It is said that professional test flights should be carried out in the test flight institute, where the equipment is the most perfect, but now, in order to speed up the progress, those who can test flights here will directly test flights here.

"Eight thousand in height, six hundred in speed, now, request to turn on afterburner." Tang Gang shouted inside the intercom.

"Yes, pay attention to all kinds of meters." There was an echo in the headphones.

"Understood." As soon as Tang turned on the afterburner, at this moment, the Vortex Jet-7 became irritable, and a huge feeling of pushing back came from behind, which was almost the same as the Flying J-7!
