Chapter 417 The equipment urgently needed by the troops

Previous page        Return to Catalog        Next page

    Zhuang Jianye¡¯s heart skipped a beat, thinking that it could be because the aircraft failed the static test and the overall design was completely rejected, which would be troublesome.

    It's quite sad to say that, apart from playing with composite materials, Tengfei Aviation Manufacturing Corporation is very weak in other aspects. If I had known this, I would have reserved some aviation materials imported from Europe. Now it's good, all of them have been paid in advance.  Give it to the army's logistics department.

    How can this be fixed?

    Zhuang Jianye immediately became worried. He frowned and was about to ask about the specific situation when he heard an old voice on the other end of the phone say urgently: "Why can't you talk to the point? Give me the phone."

    After a burst of noise, Ding Laixiang's solemn and resonant voice rang out from the phone receiver in Zhuang Jianye's hand: "Xiao Zhuang, I can't tell you clearly on the phone. I suggest you come to the food market. The sooner the better, eh~~  In this case, we will have a technical discussion soon, so we will hang up first."

    As soon as Zhuang Jianye was about to speak, Ding Laixiang hung up the phone. Zhuang Jianye almost spat out a mouthful of blood. Lin Guanghua didn't get to the point, but you, Professor Ding, got to the point?

    However, regardless of whether it is important or not, the improved Yun 5 is the biggest priority, so I have to go to the food market no matter what.

    In fact, Zhuang Jianye should have gone there long ago. Unexpectedly, before departure, the leader of the health department, Hong Xiaosong, and the head of the army logistics department suddenly informed him that they would come to investigate the new products of Tengfei Medical Equipment Company.

    So Zhuang Jianye left the static test of the aircraft to Lin Guanghua and stayed at the headquarters waiting to receive the two leaders.

    Now that the leader has left with satisfaction, the newly developed medical equipment has been recognized by the army's logistics department, and another order is about to be secured. Zhuang Jianye doesn't have many important matters at hand, so he entrusts the company to Shen Jianwei and Huang Feng, and he  After going home and packing my things for two days, I boarded the train to get food under Ning Xiaohui's reluctant eyes.

    ??Then we transferred to the car, and after a bumpy journey, we finally arrived at the aircraft testing center. As soon as we got off the bus, Ding Laixiang and several other old professors from the review expert group gathered around us.

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

    "Well, I really didn't expect that your new structure would have such performance." Professor Sun nodded in agreement.

    "I have to say that my previous thoughts were indeed conservative. Mr. Zhuang, your aircraft is really excellent." Researcher Qian stroked his glasses and spoke with great sincerity.

    Zhuang Jianye was a little dizzy, wondering why the attitudes of these people have become so kind?  You must know that when the expert review group was first established, the senior members were very critical of themselves. How come it has changed so quickly now?

    ??????????????????????? However, there was doubt in his heart, but one thing made Zhuang Jianye completely put his mind at ease, because this at least showed that the improved Yun 5 had survived the static test, otherwise the elders would never have done this.

    "You are Mr. Zhuang from Tengfei Headquarters, right?" As Zhuang Jianye was thinking quickly in his head, a tall middle-aged officer wearing an Air Force uniform smiled and stretched out his hand to him. Zhuang Jianye quickly reached out and shook his hand.  He said politely: "You can just call me Zhuang Jianye, uh the leader is"

    "Oh, I am Wu Changcheng, deputy director of the Flight Test Center, and I am also a new member of the new aircraft model expert review team designated by my superiors." Wu Changcheng introduced himself politely.

    Zhuang Jianye's thoughts were already a little confused, and now he was even more confused. If he remembered correctly, the Improved Y-5 should not have anything to do with the military. Why did a member of the review expert panel with a military background suddenly appear?  ?  But he was assigned by his superiors, so what happened?

    Seeing Zhuang Jianye's dumbfounded look, Lin Guanghua, who finally found a chance to speak, quickly came over and whispered to Zhuang Jianye. Zhuang Jianye's dull face immediately became very exciting, and then he looked at Wu Changcheng's unbelievable expression.  Question: "The Air Force is optimistic about our improved Y-5?"

    "Yes." Wu Changcheng smiled and nodded: "Our research believes that this model of yours is an urgently needed equipment for our troops." After saying that, he led Zhuang Jianye towards the reception room, and then reported the situation during this period.  I said it roughly.

    It turns out that the 30% service load test started shortly after the improved Y-5 was hoisted to the static test bench a few days ago, which took 120 hours.

    Wu Changcheng, Ding Laixiang and others thought that if the annular load-bearing structure of the improved Y-5 was removed, the overall indicators would be ugly. However, when the data came out, Wu Changcheng, Ding Laixiang and others were shocked. The maximum deformation limit was less than 3% of the total deflection.  , the residual permanent deformation reaches an astonishing 0.024%.

    It should be known that in the 30% service load test of general aircraft, the maximum deformation is limited to less than 5% of the total deflection, and the residual permanent deformation is not more than 0.2%, which is considered qualified.

    And the improved modelHowever, ??5 achieved these two indicators at 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% load tests, and the data is as good as ever.

    As a result, several old professors were a little uneasy. There is no annular load-bearing beam, which reduces the use of riveting processes. The integrated molded improved Y-5 is actually better than the aircraft using traditional materials and processes.

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

    The lighter the aircraft, the more benefits it will bring. The ultimate indicator is that while the rated power remains unchanged, the loading capacity will be greatly increased, the practicality of the aircraft will be greatly expanded, and the designers will have more room to play.  will be bigger.

    Therefore, several old professors who originally held conservative opinions on the improved Yun-5 simply threw their previous suggestions behind and grabbed Lin Guanghua to start technical discussions on the performance advantages demonstrated by the improved Yun-5.

    If it were anyone else, with Lin Guanghua's out-of-the-box character, he would at least have a classic show of pretending to be 13 and getting slapped in the face. The problem is that except for Wu Changcheng, the rest of the old experts are either his mentors or have taught you  The teacher who teaches the class wants to pretend to be 13. I guess a few old professors can turn him into a scumbag with just one slap.

    So I was very self-aware and not impulsive. I spent the day on the static test bench recording data, and at night I exchanged some experiences with several experienced experts on the development of the improved Y-5.

    Until one day, the head of the Air Force suddenly came to the test center for investigation. 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 proposed preliminary improvements.  Opinion.

    Lin Guanghua was stunned at the time. He really didn¡¯t expect that the improved Y-5 could be included in the Air Force¡¯s equipment development sequence.

    Not to mention Lin Guanghua, even Zhuang Jianye is a little confused now. What's going on?  Is this going to build aircraft for the Air Force?
