"Qin Feng, what happened yesterday?" The next day, he returned to the test flight yard, stood on the runway, and waited for the test flight, Tu Lao asked Qin Feng.

Yesterday, after Tu Lao came back, he was still busy working, and suddenly received a phone call, Qin Feng called, and his speech was very confusing.

Qin Feng's face was also full of helplessness, watching Saad and Nabil come out, and said, "If I didn't call you yesterday, Nabil's bath last night would probably have to wait until the water came today to continue washing." ”

That woman is so angry, and later she moved out the minister of the Third Machine Department and threatened to remove her, which can be regarded as subduing her, in fact, where did she call the Third Machine Department, and she called Tu Lao directly.

When the water supply was restored, poor Nabil had been waiting in the house for an hour, and it was really difficult to deal with such a woman.

When Qin Feng remembered what happened last night, he felt extremely angry.

Fortunately, it has been resolved.

Today, the guests are going to fly this modified fighter, after Qin Feng finished speaking, he watched the two Pakistani pilots come over, took them, and briefly familiarized themselves with the cockpit, Qin Feng watched them fly solo.

For them, test flights are not difficult.

The biggest problem with flying a different fighter is familiarity with the instruments. Different aircraft, the instrument position is different, so that when the pilot comes to fly, he needs to know all the instrument information at a glance, at this time, the pilot must go through a period of familiarity before he can get on the plane.

In particular, Western fighters, such as the current F-16, already have a downward-looking display, and it will take a long time to become familiar with the operation of this display.

However, the current J-7 is not used, the J-7 sits in it, and the dashboard of the J-6 is almost no different, and the layout of each instrument and button is exactly the same.

This is also the manufacturing concept of the Soviet Union, as long as the training can fly one kind of fighter, then, when you fly other fighters, you will be very adaptable, almost the same, easy to pilot.

Of course, pilots are actually inconvenient, they are quite distressed in the middle of so many instruments, it is not ergonomic at all, they are miserable at the beginning of the adaptation, but once they get used to it, then it is very simple.

This is just the opposite of the West, for example, even if it is an F-16, the cockpit in the early and late stages has changed a lot, and it must be changed to fly, but the newer the design, the more comfortable it will be to use.

Now, Pakistani pilots want to test flights, and Qin Feng is not ambiguous, just like he did in France, he will soon be able to fly the Mirage 2000, and the Pakistani brothers want to fly the J-7, it is also very easy, as long as they fly the J-6.

The two-seater J-7 will not appear for several years, and all the J-7 pilots will fly directly after flying from the J-6, so there is no big problem.

The first sortie of the two pilots was not a J-7 modified avionics, but the original fighter, which flew a test flight and became familiar with the operation before flying the new J-7.

Just after seeing the two pilots go into the sky, General Ajamal listened to everyone's explanation, and his inquiries about the J-7 modified avionics were more detailed this time.

A few days later, after flying several avionics modifications, the two pilots praised the improvements, and General Ajamal left them to continue the test flight, and the rest of the crew left.

Watching them leave, Tu Lao felt the pressure on his shoulders heavier again.

The model of the J-7 is complex, the initial delivery, called the J-7B, and now the test flight is the J-7 II.A, these two types of aircraft, are not the real J-7M, J-7M, it can be said that it combines the advantages of the two, both the J-7 II.A advanced avionics, as well as the J-7B modified wing hardpoints, increase the fuel in the plane and so on.

Now, so to speak, time is of the essence.

"If we want to be in a hurry now, we have to take an unusual path." Finally, Tu Lao made up his mind.

Taking advantage of the fact that two Pakistani test pilots were testing their own modified aircraft again, Tu Lao led everyone to start a discussion.

"Yes, if we follow our original manufacturing rules, we will definitely not be able to deliver according to the time specified in the contract." Qin Feng also said on the side.

According to the law of aircraft manufacturing, the development of aircraft models, in addition to the demonstration and approval of the index scheme, must first pass a complete finalized test flight, expose the problems in the design, continuously improve, and then finalize the design. After finalization, dozens of aircraft should be divided into several small batches of production for repeated process identification, and finally the production finalization can be achieved in batches to ensure stable product quality, which is the four stages of aircraft production.

But now, where is the time to do this, the term of the contract is getting closer and closer, and now Marconi's avionics, technical problems are constantly being eliminated, and now these are all models under development, and there are pre-production avionics equipment, in short, this step by step, time can't catch up!

"Therefore, I have decided that we will first produce a batch of J-7M aircraft without imported equipment, and when it is judged that the aircraft structure and system modification are feasible, we will put into the production of 10 parts of the aircraft to seize the cycle of exporting aircraft."

The production of aircraft is long, if you wait until everything is tested, and then start production, it will definitely be too late, so now, although avionics has not been completely finalized, however, avionics has a certain foundation, as long as the design is repeatedly demonstrated, carefully engaged, strict testing, to avoid errors, manufacturing can only try to pass the manufacture of these ten aircraft, do a good job of more than 1,300 new parts of the process appraisal work.

In this way, the cycle is guaranteed, and when the avionics are ready, the avionics are directly installed, and the ten aircraft can be delivered. "Tu Lao, if we do this, the risk is not small." Qin Feng said.

Now Qin Feng is definitely not just a test pilot, but also involved in the production and research and development of the front line, now, he knows, this can grab the cycle, but it is also risky, for example, once the follow-up equipment is problematic, the early parts may be invalid, what if the later electronic equipment is large? What if the line connection changes and the hole has to be drilled, and the hole is drilled to strengthen a component?

As a result, some parts may be wasted.

Tu Lao looked at Qin Feng and said solemnly: "Yes, this kind of practice is both unprecedented and responsible for our vast number of craftsmen. ”
