McDonald Jr. moved quickly, and it only took half a month for McDonnell Douglas to come up with a technical feasibility report on changing the DC-10/MD-11 from three to two.

It must be admitted that although McDonnell Douglas is a little downtrodden now, the technology and capabilities are still there, and this feasibility report that only took half a month to come out cannot, of course, it can't be too detailed, but although this report is very rough, there are all the things that Chen Geng wants: for example, after removing the tail engine, how much adjustment and modification need to be made to the overall aerodynamic layout of the aircraft, how long does it take to complete this part, how long does it take to verify, how much does it cost, and what will it be for DC-10 in the future/ The MD-11 is retrofitted, how long the construction period will take, and of course, the most important part: the cost.

Although it is only a rough report, it is also more than 30 pages long, after reading this report, Chen Geng breathed a sigh of relief: "According to this report, the amount of work in the whole project is actually not very large, and there is no need to make any modifications to the fuselage and main wings, the only thing that needs to be done is to redesign the vertical tail and flat tail, and then rematch the aircraft's control system and on-board computer system...... Mike, it's just a little bit of a project, it doesn't take half a year, right?"

The report mentions more than that, such as the problem of the maximum thrust drop after removing the tail engine, without any shortening measures for the fuselage, the only way is to reduce the fuel load, and the way is to close the two fuel tanks, the fuel tank will be reduced from the current 165.3 tons to 129 tons, however, although there is 36.3 tons of fuel less, but because of the overall weight reduction and the fact that these fuels only need to supply two engines, the maximum range of the aircraft is not greatly affected, from the original 12,700 kilometers to the theoretical 11,200 kilometers, only 1,500 kilometers.

For example, DC-10 is the most criticized problem, but also caused a number of fatal accidents caused by the small vertical tail area caused by the problem of having to land at a higher speed, after replacing a larger area of the vertical tail can be solved, because the tail engine is removed, the area of the new vertical tail is equivalent to 2.5 times the original, the lateral stability of the aircraft is better, and the controllable rudder surface on the vertical tail is also larger, which means that the aircraft is allowed to land at a lower approach speed, which is also the most important place for Chen Geng.

McDonald Jr. smiled: "You should understand, these guys...... You have to give yourself enough margin. ”

Chen Geng's face was noncommittal: "I can understand, but the question is the current McDonnell Douglas, can you afford to wait?"

Little MacDonald's face suddenly changed slightly.

He suddenly realized a problem, and he was happy to be patronized, but he forgot how serious the situation was facing McDonnell Douglas now.

"Then what do you mean ......"

Chen Geng said resolutely: "We must complete all the design, matching and corresponding test work as soon as possible, the test work can be a little later, but the corresponding modification work must be completed within three months, and after three months, we must come up with a prototype that can be shown to various airlines...... What do you think, Jack?"

Jack Welch has just signed a contract with McDonnell Douglas and officially began to serve as the CEO of McDonnell Dalwells Group, and Jack Welch has also become the only senior professional manager in the world who serves as the CEO of two large enterprise groups at the same time.

Facing the eyes of his boss, Jack Welch nodded: "I think it's okay, and it should be highly confidential, but in this way, the cost will increase a little." ”

As for why it is secrecy, of course, it is to guard against Boeing.

Hearing Jack Welch talk about this problem, Chen Geng suddenly smiled: "Let's do it first, money is not a big problem," after a pause, Chen Geng continued: "Jack, this is a rare opportunity for you." ”

What chances?

An opportunity to establish one's authority within the McDonnell Donnell Douglas Group, of course.

Although Jack Welch is already recognized as a top professional manager in the world, the relationship within the McDonnell Douglas Group is intertwined, and even with the promise that McDonald Jr. promised to split at the right time, those people in the original Douglas department are no longer so noisy and pulling their backs, but for Jack Welch, a new professional manager, the people in the Douglas department are still very hostile to him: This position should be given to us to sit in.

Chen Geng naturally knew that the Douglas department within the McDonnell Douglas Group was very unhappy with the arrival of Jack Welch, so he said that this opportunity was rare for Jack Welch.

Little MacDonald naturally understood the meaning of Chen Geng's words, and immediately looked at Jack Welch.

"Don't worry. Jack Welch nodded immediately.

........................

It must be admitted that in terms of management ability, McDonald Jr. is indeed a lot worse than Jack Welch, or rather, the old good man manager simply can't manage a company well, after taking over the position of chairman of McDonnell Douglas Group from his father, McDonnell Jr. has been a mess of McDonnell Douglas, but since he gave up the position of CEO and handed it over to Jack Welch, because of the full cooperation of McDonald Jr., relying on the simplest and most effective "beating a group of people, pulling a group of people" Jack Welch quickly opened up the situation in a very short period of time, and the little MacDonald was dumbfounded, and he kept sighing with Chen Geng.

After opening up the situation, Jack Welch quickly started his first big move since joining McDonnell Douglas, which was to "subtract" the DC-10/MD-11.

I have to admit that McDonnell Douglas has good experience in large aircraft technology is indeed the world's top, after Jack Welch quickly established his authority by means of grace and power, the entire McDonnell Douglas Group's technology and R&D team no longer dared to perfunctory and responsible, all departments fully cooperated, and the whole project started quickly.

With the close cooperation of various departments, it didn't even take three months, only 80 days, and the first DC-10 that had completed the modification began its first test flight, which was fast and terrifying.

Looking at the DC-10, which is much slower than before and much more stable than before, the expression on McDonald's face keeps changing: on the one hand, he is proud and proud of the technical level and speed of McDonnell Douglas Group in this DC-10 three-engine to double-engine, but on the other hand, he is a little embarrassed...... He still clearly remembers that in the original report, it was clearly stated that half a year is the shortest period, and there is no way to shorten the time.

The 80-day-old report is still in his office, but now the plane has landed......

"Don't think about it," Chen Geng patted McDonald Jr. on the shoulder, met McDonald's obscure gaze, Chen Geng said softly: "Everyone has a suitable position for themselves, for those of us who are bosses, the most critical issue is to have self-knowledge and know to put the right person in the right position, just like me, I know that I will not be a qualified professional manager, so I have never been responsible for the specific management of the enterprise......"

Without waiting for Chen Geng to finish speaking, little MacDonald said faintly: "Are you saying that I haven't been self-aware all these years?"

Regardless of McDonald's ugly look, Chen Geng laughed and pointed to the twin-engine version of the DC-10 on the runway that had begun to turn around: "Do you still need me to say it? This is the best evidence!"

"You're really ......" Little McDonald sighed, a little embarrassed, but at the same time a little relieved: "Don't save me any face." ”

"Haha...... Let's go, go over and listen to what the test pilots have to say. ”

Chen Geng didn't say anything more, but patted little McDonald on the shoulder and laughed!

In fact, there is no need for Chen Geng to say it, McDonald Jr. is more anxious than Chen Geng, and he also wants to hear the test pilot's evaluation of the twin-engine version of DC-10.

"Very good, sir," in the face of McDonald's eagerness to rush directly to the cab, the test pilot on the twin-engine version of the DC-10 understood his boss's mood very well, and the No. 1 test pilot sitting in the captain's seat immediately explained to McDonald Jr.: " Compared to the original DC-10, this aircraft feels a little bit worse thrust when it takes off, but it is only a little bit, and overall it is completely sufficient, and I think that even with one engine removed, the performance of this aircraft can fully meet the needs of airlines.

As for the low-speed performance and stability when landing, you should actually see it, very good, very good, even better than we imagined, compared to the previous DC-10, this DC-10 has a 25 km/h lower approach descent speed than the previous three-engine version of the DC-10, and the lateral stability is better.

Although this is only our first test flight, and there is still a lot of test flight work to be carried out, we can now think that some unsolvable stubborn problems caused by the three releases of the DC-10 have been solved because of this improvement and upgrade, of course, if the engine can be replaced from the current CF6 and JT9D to the PW4000 series, CF6-80 series with greater thrust, it is estimated that the performance of this aircraft will be better. ”

Little MacDonald nodded his head again and again, his face full of red light!

He was so happy, because what the two test pilots said was what he wanted to hear the most, and after the introduction, McDonald Jr. first hugged the entire test aircraft team excitedly, told them that the company had prepared a sumptuous celebration meal for them, and learned Chen Geng's habit to send them a big red envelope of 10,000 US dollars, and then McDonald Jr. hugged Chen Geng very excitedly: "Fernandez, my friend, I am now sure that you are my angel of good luck!" I've had a lot of good luck since I hit you as my advisor...... God, I'm such a fool, I should have realized this a long time ago......"

This guy was a little out of shape with excitement.

........................

With this successful test flight, whether it was Chen Geng, McDonald Jr., or Jack Welch, they were completely relieved, and after a week of intense test flights, McDonald Jr., in the name of the chairman of McDonnell Douglas Group, sent an invitation to those airlines that are still using DC-10 and MD-11, inviting them to visit and inspect this batch of "three to two" versions of DC-10 at McDonnell Douglas Group headquarters.

Chen Geng underestimated the reaction of those airlines that were using the DC-10 and MD-11.

He originally thought that the response of these airlines might not be very enthusiastic, but what Chen Geng didn't expect was that when McDonald Jr.'s invitation was sent, those airlines that received the invitation letter immediately responded, and after personally confirming that McDonnell Douglas Group did come up with a double-engine version of DC-10 and MD-11, and that they could indeed spend a certain amount of money on the basis of the existing models to complete the modification and upgrade, they were boiling.

PS: Sorry brothers, please wait a few minutes.

Although this is only our first test flight, and there is still a lot of test flight work to be carried out, we can now think that some unsolvable stubborn problems caused by the three releases of the DC-10 have been solved because of this improvement and upgrade, of course, if the engine can be replaced from the current CF6 and JT9D to the PW4000 series, CF6-80 series with greater thrust, it is estimated that the performance of this aircraft will be better. ”
