Zhuang Jianye chuckled in his heart, and said in his heart that it would not be because the static test of the aircraft failed, and the overall design was completely denied and returned, which would be troublesome.

It's also quite sad to say, Tengfei Aviation Manufacturing Corporation is weak in other aspects except for the transfer of composite materials, and it has known that in this way, it has left some aviation materials imported from Europe, and now it is good, all of them have been advanced to the logistics department of the troops.

That's a whole thing.

Zhuang Jianye was immediately worried, frowning and just about to ask about the specific situation, he heard an old voice on the other side of the phone say eagerly: "Why can't you talk to the point, give me the phone." ”

Then after a burst of noise, Ding Laixiang's serious and loud voice sounded in the telephone receiver in Zhuang Jianye's hand: "Xiaozhuang, the phone is not clear, I suggest that you still come to the grain market, the sooner the better, well~~ That's it, we will have a technical meeting soon, hang up first." ”

Zhuang Jianye was just about to speak, Ding Laixiang had already hung up the phone, Zhuang Jianye almost didn't spurt out a mouthful of old blood, Lin Guanghua didn't get to the point, you Professor Ding got to the point?

However, no matter whether it is important or not, the matter of improving the transportation 5 is the biggest focus, so this trip to the grain market is also a trip.

In fact, Zhuang Jianye should have gone over a long time ago, but he didn't expect that before departure, Hong Xiaosong, the leader of the health department, and the head of the logistics department of the army suddenly notified that they would come over to investigate the new products of Tengfei Medical Equipment Company.

Therefore, Zhuang Jianye handed over the matter of the static test of the aircraft to Lin Guanghua, and stayed at the headquarters to wait for the reception of the two leaders.

Now that the leaders are satisfied, the newly developed medical equipment has been recognized by the logistics department of the army, and another order is about to be settled, Zhuang Jianye has not much important matters at hand, so he entrusted the company to Shen Jianwei and Huang Feng, went home and packed his things for two days, and then stepped on the train to the grain under Ning Xiaohui's reluctant gaze.

Then I turned to the car, and finally arrived at the aircraft test center after a bumpy ride, and as soon as I got out of the car, Ding Laixiang and several other old professors of the review panel came around.

"Xiaozhuang, your factory impressed me again!" Ding Laixiang came up with a very rare compliment.

"Well, I really didn't expect your new structure to perform like this. Professor Sun nodded in agreement.

"I have to say that my previous thinking was really conservative, Mr. Zhuang, your plane is really good. Researcher Qian stroked his glasses and said very sincerely.

Zhuang Jianye was a little dizzy, and said in his heart, how did the attitude of these people become so kind? You must know that when the expert review team was just set up, the old ones were picking their noses and eyes at themselves, how could they turn so fast now.

However, the doubts in his heart are doubts, but there is one thing that makes Zhuang Jianye's hanging heart completely let go, because this at least shows that the improved Yun 5 has passed the static test, otherwise the old few will never be like this.

"You are Mr. Zhuang of Tengfei Headquarters. Just as Zhuang Jianye was thinking quickly in his head, a tall middle-aged officer wearing an air force uniform stretched out his hand to him with a smile, Zhuang Jianye quickly stretched out his hand to hold it with the visitor, and said politely: "You can call me Zhuang Jianye, eh...... The chief is ......"

"Oh, I'm Wu Changcheng, the deputy director of the flight test center, and I'm also a new member of the expert review team for new aircraft models designated by my superiors. Wu Changcheng politely introduced himself.

Zhuang Jianye was already a little confused, and now he was even more confused, if he remembered correctly, the improved Yun-5 should not have anything to do with the military, what happened to the sudden emergence of a member of the review panel with a military background?

Looking at Zhuang Jianye's stunned and unintelligible look, Lin Guanghua, who finally found a chance to speak, hurried over and whispered a few words to Zhuang Jianye, Zhuang Jianye's wooden face immediately became very exciting, and then looked at Wu Changcheng and asked in disbelief: "The Air Force is optimistic about our improved Yun-5?"

"Yes. Wu Changcheng smiled and nodded: "We believe that this model of yours is the equipment that our troops urgently need." As he spoke, he led Zhuang Jianye towards the reception room, and then roughly explained the situation during this time.

It turned out that a few days ago, not long after the improved Yun-5 was hoisted to the static test bench, it began to test 30% of the use load, which was 120 hours.

Wu Changcheng and Ding Laixiang and others thought that the improved Yun 5 removed the annular load-bearing structure, and the overall index would be ugly, but after the data came out, Wu Changcheng and Ding Laixiang and others were surprised, and the maximum deformation was less than 3% of the total winding, and the residual permanent deformation reached an astonishing 0.024%.

It is important to know that the 30% use load test of the general aircraft limits the maximum deformation less than 5% of the total winding, and the residual permanent deformation is not more than 0.2%.

However, the improved Yun 5 has achieved these two indicators of 3% and 0.024%, indicating that its overall structure is not only stable but also safe.

This is no longer qualified, it is simply excellent.

The same is true for the subsequent 45% and 60% of the load tests, and the results are as good as ever.

In this way, several old professors are a little uneasy, there is no annular load-bearing beam, reduce the use of riveting process, and the improved Yun-5 with integrated molding is actually better than the traditional materials and processes of the aircraft.

It is equivalent to saying that the overall structure of the improved Yun 5 is not only reasonable, but also can be made lighter.

The ultimate indicator is that under the condition of the same rated power, the loading capacity will be greatly increased, the practicality of the aircraft will be greatly expanded, and the designer will have more room to play.

As a result, several old professors who originally had conservative opinions on the improved Yun-5 directly put their previous suggestions behind them, and grabbed Lin Guanghua and began to discuss the performance advantages of the improved Yun-5 technically.

If this is someone else, with Lin Guanghua's out-of-the-box character, at least there will be a classic drama of pretending to be 13 and slapping his face, the problem is that several old experts except Wu Changcheng, the rest are either his tutors, or the teachers who once taught you, and if you want to pretend to be 13, it is estimated that a few old professors can slap him into scum with one slap.

So I was very self-aware and had no impulse, soaked in the static test bench during the day to record data, and exchanged some experiences in the development of the improved Yun-5 with several old experts at night.

It was not until one day that the head of the Air Force suddenly came to the test center for investigation, and after listening to the introduction and opinions of Wu Changcheng, Ding Laixiang and others on the improved Y-5, he said that this model could be included in the Air Force's equipment research and development sequence, and put forward preliminary suggestions for improvement.

At that time, Lin Guanghua was stunned, and he really did not expect that the improved Y-5 could be included in the development sequence of air force equipment.

Not to mention Lin Guanghua, even now Zhuang Jianye is a little confused, what is the situation? This is going to build an airplane for the Air Force?
