As the plane was put on the runway, Li Zhao and others also went to the stands, watched from a distance, and tried not to give the test any accidents, and soon the plane started again, with the increase of engine thrust, the plane slowly began to slide on the runway, from slow to fast, and then slowly decelerate, and then turn to go back.

In this process, the flaps and tail rudder of the aircraft are constantly doing movements, obviously also testing the flight control system, of course, when the fuel consumption reaches a certain level, the weight test is also carried out, and in this way, back and forth, until all the fuel is exhausted, the test is over, and the time is three hours later.

Today's test, has preliminarily tested the various systems of the aircraft, although it is not known what will happen after a long period of operation, but obviously, there are no more serious problems today, for the time being, it can be said that the operation of each system is good, in this case, the aircraft has been completed more than half.

At this time, everyone was very happy, not only the members of the project team, but also the pilots, ground staff, and maintenance personnel, who came here to assist in the aircraft test, and now the work has officially begun.

After dinner in the evening, Li Zhao went to Su's father again and met, Li Zhao said, "Dad, today the aircraft has carried out mass distribution tests and inspections of various systems, and the current results show that there are not many problems."

Father Su also became serious at this time, and asked, "Is it time to conduct a test flight?" It's a big deal, and I'm going to have to invite some more people to do it, and this is the first aircraft we've developed independently, and it's so advanced."

Li Zhao is afraid of this, so this test, did not invite others to visit at all, after all, the next thing to be carried out is the static test, but it is still far from the test flight, and the fastest is two or three months later, after all, there is no complete production process, let alone a complete installation process and production line, it takes a long time to manufacture an aircraft, although there are many machine tools and personnel in the factory, it is the same.

Li Zhao also went on to explain at this time: "It is still far from the test flight, and the next test is the static test, that is, according to the flight attitude to analyze the force of the aircraft, and then apply a certain force at the corresponding part to test whether the strength of the corresponding position of the aircraft is up to standard, under normal circumstances, this strength needs to reach one hundred and five percent of the required strength, so that the weight of the aircraft is the most appropriate, if it is high, then it means that the strength is excessive, the aircraft will be heavy, then the aircraft needs to lose weight, as for the low, it is even worse, If you fly like that, you might get into trouble."

After listening to Li Zhao's words, Father Su knew that there was still such a test, and said, "Okay, let's carry out the next stage of the test as soon as possible, but how long will this stage take? There are a lot of people waiting for the results now."

Li Zhao can't actually give an exact time, but the approximate time can still be thought of, so he said: "It is estimated that in September, as long as the static test of the main body is completed first, the next one can be produced, and we will need about two months to produce and assemble one, and we will strive to complete these tests as soon as possible." ….

After hearing this, Father Su said in a deep voice, "Why don't you let the leaders take a look and let them know our progress, at most it will be a day's delay, how about you do today's test again?"

Li Zhao can also understand Su's father's thoughts, to tell the truth, the pressure on all the *** members in the factory is very great, after all, the investment in this project is too large, more than one billion has been invested, this is a very large amount of money, definitely not less than five or six billion after sixty years, of course, a lot of factories have been established, and the results achieved are also a lot, but after all, the goal is the aircraft, and before it is taken out, it is not easy to explain.

Now there is the first verification machine, the results of today's test are not bad, take it out to the leader, it can be regarded as making the leader more confident, after all, on this project, the support of the leader is not small.

Li Zhao thought for a while and said: "After reading it, I am afraid that the leader will urge too much, after all, before the strength test, the plane obviously cannot be tested, you also know how strong the thrust of our engine is, I am afraid that the strength is not enough, directly come to more than twice the speed of sound, and directly run apart, then the problem is too big."

Father Su said at this time, "In this way, tomorrow will be direct

Engage in a taxi-run test, and then pull the plane over and start the static test directly in front of the leader, so that the leader should not be able to urge."

After Li Zhao heard this, he also felt that it was okay, after all, as soon as the static test was done, the key components might be damaged directly, and it would be impossible to do any more test flights.

After the discussion was completed, Su's father went out directly to the factory, which was going to call the leader directly, but since it was decided, Li Zhao would not regret it, the next morning, Li Zhao came to the test workshop, and told everyone the results of yesterday's discussion with Su's father, today's test preparations began, and the most important thing is to prepare the equipment for the static test, once the same tests as yesterday are completed, the static test will start directly.

In the past, the static test was relatively simple, there was no special equipment, and it was often tested by adding sandbags to the corresponding parts of the aircraft, and Li Zhao obviously would not be carried out like this, and now the factory has directly built a special static test device, which can apply the required force to the aircraft from all directions and points, so that it can be more convenient and accurate to measure the various deformations of the aircraft under the force.

Just when everyone was preparing, Father Su came directly with the leaders, this time there were still a lot of people coming, but looking at the level is much higher than usual, it is also difficult for Father Su, last night notified so many leaders, and let the leaders come over so early, you must know that it is not half past eight o'clock, and the leaders who are far away are estimated to set off at six o'clock, and after coming, there is no delay at all.

However, when they saw the plane, everyone should feel that they did not lose money today, but this plane has far exceeded their imagination, more than 20 meters in length, making them feel that this plane is not the same as the plane they usually see, and the difference between the two is too great. ….

Especially the use of countersunk screws, although the fuselage is not coated, but still make them feel different, after all, the gap in the process is too big, the more you look at the more you feel that the plane you have seen before is backward, and now these people are eager to grow their eyes on the plane, everyone looked around the plane for a while, Li Zhao began to introduce the parameters of the aircraft, but they don't know how many times they have seen these numbers, obviously they already know it.

After Li Zhao finished speaking, a leader asked, "What are the main projects today, and is the test flight a test?"

Li Zhao smiled bitterly when he heard this, and couldn't help but look at Su's father, seeing that Su's father was also smiling bitterly, Li Zhao could only bite the bullet and say: "Leader, the project has not yet advanced to the test flight stage, we are a completely newly designed aircraft, there are a lot of items that need to be inspected, and more projects need to be carried out than imitation.

Li Zhao was afraid of this, so he didn't invite the leader to come, after all, the leader came to see the test flight, what are you looking for on the ground? However, without completing the static test, Li Zhao obviously could not test fly.

At this time, Su's father also explained to the leaders, and after a while, he persuaded the leaders to start testing according to the plan, which was similar to yesterday, but a lot of test links were omitted, but when the plane completed a few rounds of sliding, the leaders no longer said anything, after all, they were very satisfied with the progress of this link, after all, in addition to not flying into the sky, all kinds of matters on the ground were completed, which made them more confident.

Soon the plane was dragged into the static test equipment, and the new test began, when the leaders looked at the slightly deformed aircraft because of the application of external force, Li Zhao also began to give the leaders a timely science of what is the static test, to be honest, the leaders are rarely seen this kind of scene, after all, when imitating the aircraft, many tests can be omitted, after all, various tests have been done in others.

Of course, at the beginning, the force applied is not excessive, only twenty or thirty percent of the design strength, after all, the first thing that needs to be tested is the overall situation, can not catch a point desperately afterburner, and then directly scrap that point, it always needs to be done step by step, of course, in the end, it must be carried out in the static destruction test of the whole aircraft, then the overall strength of the aircraft can be measured, and when the time comes, it will be based on this

Testing optimized aircraft.

After all, the best design is to design the strength of all positions to just one hundred and five percent of the required strength, but it is often impossible to achieve it directly, the design is too bold, it may not be reached, and the conservative design may exceed one hundred and five percent, and Li Zhao is obviously conservative here, but I don't know to what extent it is conservative, these need to be tested to know, of course, Li Zhao still has points in his heart.

This time, because it is an airplane, Li Zhao's design is not so conservative, and it is estimated that it will be about 108 to 11 percent, and in this case, the weight of the aircraft is already too heavy.
