After a while, Su Xihua brought Hong Huan over, and Ma Tian also asked Tianji on the screen of the conference room to list the steps to resolve the disputed issue.

"Let's sit down first." Seeing the arrival of the two, Ma Tian also motioned for the two to sit first, then paused, organized the language, and then spoke:

"You must all know the design concept of the White Emperor's vertical take-off, but now you are arguing about whether the engine design of the two nozzles in the belly is in the form of a turbine or a turbofan.

In my opinion, it's better to stick to the form of turbine improvements! ”

Ma Tian supported his own point of view, although the turbofan is more suitable for low-speed operation, its instantaneous jet speed is too small, and the thrust generated is not stable enough.

As soon as Ma Tian's words came out, Hong Huan naturally disagreed, and he raised his own questions: "The turbojet speed is too fast, and the performance is low, if one of them is not controlled well in the vertical landing, it will be over." ”

"Why do you think we're going to be out of control?" Ma Tian retorted.

"No, this control is uncontrollable, under the huge energy of the turbojet, the turbine pipe structure is very easy to deform, you can't change the engine every time you take off, right?" Hong Huan insisted on his opinion.

In his opinion, Tianyu Xinghai is inexperienced, and he didn't consider the deformation of the pipeline material caused by the high-temperature gas sprayed in the case of vortex jet.

"Look at the formula I calculated on the screen, in my opinion, the deformation of the pipe by temperature is within the deviation range!"

Ma Tian motioned to Hong Huan to look at the calculation formula on the screen, in his calculation, the effect of the high-temperature gas injected by the turbine on the deformation of the pipeline is much different from that of the turbofan.

That is to say, whether it is in the form of a turbofan or a turbine, the final result does not affect the control, but in vertical stabilization, the huge thrust brought by the turbine in a short period of time is required.

Hong Huan looked at the formula calculation on the screen:

y*（w*Tcomp）= m_dot*(h4-h1)

INe = Te - Ti

……

w is the speed of the compressor, Tcomp is the torque of the compressor, m_dot is the air flow, h4 is the ......

A large number of formulas and data were marked on the screen, Hong Huan scratched his head and said, "Mr. Ma, I'll make a copy, and I'll go down and calculate it." ”

With so many formulas and data, he suddenly became more and more confused, and with a rigorous attitude, he felt that it was better to copy them down and understand them step by step at his workstation.

Ma Tian nodded and said, "Tianji will send this to your email later, and you can see it on your desk computer when you go back!" ”

Ma Tian didn't feel that Hong Huan was dragging down the progress, and the engineers who could calculate his formula by themselves were worthy of praise.

Watching Hong Huan leave, Ma Tian also continued to talk to Su Xihua about research and development:

"I've basically solved the 11 major problems, how many tasks and bugs do you have left?"

"There are 258 tasks and 85 bugs left." Su Xihua replied.

"And so many?" Ma Tian was stunned, this efficiency is too slow, he has solved more than 40 in the past 5 days.

Su Xihua didn't dare to speak, compared with the problem solved by Ma Tian, they were indeed too far behind, and they could also be seen when developing the T-X1 multi-purpose vehicle and the terrifying hell robot dog.

Basically, Ma Tian was solving the problem quickly, and the more than 60 engineers added up to only half the speed of Ma Tian at that time, and the solution was still relatively simple.

Ma Tian sighed and waved his hand: "You go down and get busy." ”

In the end, he is too anxious, always thinking about developing the "White Emperor" in a month, how can the actual situation be so fast, this is still the early stage, and the experimental simulation is a lot of problems that need to be solved.

"Well, take your time and enjoy it yourself!"

Over there, Hong Huan also returned to his workstation and began to watch Ma Tian's calculation process.

As an engineer who can be in charge of engine research and development at the research institute, he naturally has a few brushes, and mathematics and physics are his strengths.

Soon, however, he was scratching his ears and cheeks in his seat, and the pen in his hand was frantically deducing on scratch paper.

Halfway through the deduction, I tear it up and start the deduction again.

"What's wrong with you, Hong Huan?" Tang Shiyu, who was sitting at the workstation next to him, couldn't help but ask when he saw Hong Huan's painful appearance.

"It's okay, it's just to understand and deduce the formula." Hong Huan replied simply, temporarily raising his head from the complicated formula.

The formula calculated by Ma Tian is too complicated, and some steps are simply omitted by Ma Tian, and they are brushed aside, after all, it is a draft and analysis process that he wrote casually, and Ma Tian will naturally not be meticulous.

This makes Hong Huan suffer, the brain cells don't know how much to kill, and I often see a formula, to speculate why Ma Tian calculates it like this.

These formulas are more than a dozen variables at every turn, and the difficulty of his deduction can be seen.

This is also why some mathematicians are crazy, because those formulas are so fucking complicated, not to mention giving them to college students, or copying them to some mathematics doctoral students, they have to understand why this formula is done for a long time.

Hong Huan was tortured for an afternoon and only deduced 7 or 8 formulas, and there were at least twenty more formulas behind such formulas.

In order not to affect the progress, Hong Huan only has to work overtime, he must understand Ma Tian's thinking to point out and prove that Ma Tian is wrong, and the fighter belly engine should be in the form of a turbofan.

After dinner, Hong Huan gently explained to Leng Fangguo: "Leng Lao, I have a little R&D progress that needs to be rushed, and I have an extra shift today!" ”

"Okay, great work!" Leng Fangguo patted Hong Huan on the shoulder, saying that he was very pleased to see that the people on his side were working hard.

Su Xihua, who was accompanying him, couldn't help grinning at the corners of his mouth and chuckled.

It's like him before, when he first came, he was also high-spirited, thinking that Ma Tian might also make mistakes, and sometimes argued with Ma Tian.

Then he was shown off by Ma Tian, and after looking at the mathematical and physical analysis formula that Ma Tian had compiled for several days, he finally found that Ma Tian was right.

After going through it three times, he never questioned Ma Tian's opinion again, because in the end, it turned out that Ma Tiancai was right, and he just had nothing to think about.

This time, Su Xihua also knew that Hong Huan Bacheng would also waste a few days, but he didn't stop it.

Some people don't hit the south wall once and don't know the lessons learned. Similarly, Hong Huan and the others will not experience Ma Tian's level, and they will also be dissatisfied with Ma Tian's conclusions.

Perhaps, maybe the south wall will have to hit a few more times!

Ma Tianye soon returned to his laboratory and watched Tianji list Su Xihua's more than 200 unsolved tasks and bugs.

Ma Tian thought about it, but beckoned to Tianji to turn it off, and looked at it to see if he could do it himself, and began to solve it again.

Just like a patient with obsessive-compulsive disorder, even if he sees a red dot on QQ, he has to click him off, and Ma Tian sees these unsolved tasks, and he starts to solve them again.

Simply out of sight and not upset, Ma Tian left the office directly and went back to the villa for dinner.

The next day after work at 5 o'clock!
