  Chapter 109 Enhanced simulation transformation

  Tang Rui walked around the J-18 and asked a lot of questions.

  For example, the canard layout of the lifting body side strips.

  For example, the main wing with small aspect ratio and medium sweep angle.

   Well known.

   This kind of aerodynamic layout is basically aimed at the unification of the maximum lift coefficient at low speeds, the lift-to-drag ratio at sub-transonic speeds, and the drag coefficient at supersonic speeds.

   Good ideas.

   But there are many problems in it.

  Tang Rui doesn't think that Shen Huoyi has solved the problem.

   But these issues are not for him to consider, he just needs to help Shen Huoyi get the vertical take-off and landing system done.

   "What was the vertical take-off and landing lift coefficient you calculated earlier?"

   Tang Rui asked.

   "The result of the simulation on the supercomputer is 65%."

   Simulation?

   That means there is actually a problem.

   "What about the reality?"

   Tang Rui asked curiously.

  Director Liu replied with a wry smile: "Only 37%."

   Okay.

   There is a 30% difference between the calculation result and the actual test.

  Then it’s still a woolen vertical take-off and landing.

  Vertical take-off and landing can only be achieved if the lift force reaches more than 51%.

  Not to mention the problem of modifying the engine right now, but the vertical take-off and landing system itself has problems.

  Tang Rui looked up at the body of the J-18, thought for a while, and said, "You sacrificed the lift coefficient of the vertical take-off and landing system to ensure the stealth performance of the fighter?"

   "That's right, the stealth performance must meet the standard, otherwise, even if the J-18 has a vertical take-off and landing function, the Air Force will not accept it."

  Director Liu naturally knew what Tang Rui meant.

  So he didn't fool around.

   Directly stated the situation he was facing now.

  If it is not forced, there is no way.

  Shen Huoyi would not be in such a hurry.

   "Okay, I see, have you brought all the materials?"

"Brought it."

   "Give me the information, I'll go back and study it first."

"OK."

  Director Liu was very excited when he saw that Tang Rui didn't leave directly.

   Willing to help in this situation.

  Don't say you want information.

  Even if you want him to provide one-stop service, there is no problem.

   "Mr. Tang, we have sent the forward-swept wing demonstration aircraft over, do you want to see it?"

  Director Liu saw that Tang Rui was about to leave with the documents, so he immediately spoke.

   "There's no rush, just put it aside."

   Tang Rui shook his head, he is not in the mood to look at the verification machine right now.

   "Brother Yang, go home directly and not go to the company."

"OK."

  Tang Rui wants to go back and get a thorough understanding of the J-18 data, and then build a model machine.

  The reason why he is willing to help.

   It's not that he has the spirit of Lei Feng, nor is it because of the information about the forward-swept wing demonstrator.

   Instead, he suddenly thought of one thing.

   That is the vertical take-off and landing system, which is very suitable for forward-swept wing models.

   Even better than swept wings.

   In terms of aerodynamic layout.

  If the swept wing of the J-18 is changed to a forward swept wing, the lift coefficient can be increased by at least ten percent.

  If he understands this system through research, it can be used in the forward-swept wing fighter he will build next.

think about it.

  When a forward-swept wing fighter was passing the runway at low altitude and low speed, it suddenly made a 180-degree U-turn on the spot.

  That effect is simply terrifying.

  Even in his mind, the potential of this system is huge, not only can it be used in vertical take-off and landing, but it can even be used in future aerospace fighters.

   After all, the aerodynamic layout is useless when it is out of the atmosphere.

  But this system allows fighter jets to maneuver outside the atmosphere.

   This is why Tang Rui is so active.

  Go home.

  Tang Rui imported the materials into the learning machine.

   Then put on the learning machine, lie on the bed and start studying.

   Until more than three o'clock in the afternoon.

  He just woke up from his sleep.

   "Brother Yang, is there anything to eat?"

   "Yes, I bought it at noon, just heat it up and it will be fine."

   After eating.

  Tang Rui came to the company and began to manufacture J-18 model aircraft.

   "Going back to my old job."

  Starting as a model airplane again, he was also a little emotional.

  What was his condition at the beginning.

   What is the condition now.

  The equipment in the laboratory is the best, and all kinds of accessories are also complete.

   Plus Xiaoyi's help.

  Tang Rui completed the model of the J-18 in just over an hour.

   Body Enhancement -1

  Flight Control Enhancement-1

  Energy Enhancement -1

  Engine Enhancement -1

   Only 4 source points are used to strengthen the entire aircraft model.

   Watching it become a model airplane more than two meters long.

  Tang Rui didn't feel excited at all.

  Flight control system enhancement-5

   Body structure strengthening -5

  VTOL System Enhancement-5

   With a flash of light.

  Enhancement completed.

  Tang Rui picked up the airplane model and looked at it for a long time, then moved it to the workbench and began to disassemble it.

   "Xiaoyi, scanning modeling."

"OK."

  He only disassembles it, and Xiaoyi will control the robotic arm, use laser scanning equipment to scan the structure of the body, and model it on the computer.

   Half an hour later.

  The structural models of the airframe structure and the vertical take-off and landing system appear on the computer.

  Tang Rui took out his mobile phone and called Director Liu.

   "Hello, Mr. Tang."

   "Director Liu, I have redesigned the vertical take-off and landing system. Do you have a supercomputer? I want to use the supercomputer to simulate."

   "Supercomputing simulation, okay, no problem, just wait a moment."

   Less than ten minutes.

  Director Liu called and told him that arrangements had been made.

   Not Shen Huoyi's supercomputer.

   It was the computing power of Dongfang Yufeng that I bought.

   Good guy.

   Going round and round is back.

   "Xiaoyi, transfer the model to Dongfang Yufeng and start the simulation."

"OK."

   This time, Xiaoyi logged in aboveboard, not secretly opening a super administrator account.

   "Xiao Yi, how long will it take?"

   "Estimated 2 hours."

   Tang Rui nodded, got up and left the laboratory.

  Run slowly.

   Anyway, he is not in a hurry.

  After he finished his meal at night, the results of the supercomputer simulation came out.

  The simulated lift is 91%.

   Tang Rui looked at the simulation report.

  The system strengthened vertical take-off and landing system has fully met the requirements.

   And this system does not sacrifice stealth performance.

  The only sacrifice is the load of the airframe.

  But compared with vertical takeoff and landing, the sacrificed load is nothing at all.

   "Don't look, it's time to exercise."

  Li Shuyao covered the laptop and took Tang Rui to the gym.

   "Wait for me to change clothes."

   Tang Rui got up and went to the cloakroom to change.

  After a hearty workout, Tang Rui transferred the data to the learning machine and put it on to sleep.

   The troublemaker who disturbed his study has already fallen asleep at this time.

the next day.

  Tang Rui came to Ma'an Airport.

   "Director Liu, are your people here?"

   "Some people have arrived, and some people will arrive today and tomorrow."

   "Okay, gather the people who have arrived, and I will assign tasks to them."

   "Okay, I'm going to gather the people.

   That...you already have an improvement plan? "

   "There are billions of ideas."

   (Thanks to Boss Murong Xuanfeng for the reward, add another chapter)

   There are two more chapters, continue to code words.
