Hong shuibin did not comply, holding teacher he's arm back and forth: "teacher he, this is not just a chance, I really want to personally experience the whole process of the birth of variant mecha."

"That's not good either. Although the teacher helped you start the research on this project, you are not allowed to make a fool of yourself. You have to do a good job in the students' duties." Mr. He still flatly refused Hong shuibin's proposal.

"Yes, Mr. He, I won't take part." Hong shuibin knows that he is hopeless and no longer entangles himself with this issue. He just looks at it with pity.

Mr. He, who had a stern face and a serious face, was amused by Hong shuibin. He shook his head with a smile and said, "you don't have to show me such a poor picture. I'm not afraid to tell you that the mecha variant project will definitely need to test pilots in the later stage. At that time, I strongly recommend you, and you can definitely witness its appearance. "

The flood binle jumps three feet high, hugs teacher he tightly and revolves: "teacher he, thank you so much, I will never let you down."

Mr. He is very old. He has been held by Hong shuibin for several times. He feels that the world is spinning. He asks Hong shuibin to let him go to the ground. Chen Feng also quickly comes forward to help him to avoid falling down.

Mr. he held Chen Feng's arm for a while to recover. He waved his hand to let Chen Feng and Hong shuibin leave: "you all go back. I have to prepare the materials for this research group. Time is very tight. Don't delay. Let's go." They left the classroom.

In the afternoon, it was a simulation class that made everyone yearn. After several failures in the last class, everyone had their own opinions on how to operate the mecha to reach the mountain in half an hour. They all came early and wanted to try it.

Teacher Xu still took his big wine pot leisurely to the classroom, looked at the people's faces under the stage the desire of ANN Nai to smile gently, picked up the big wine pot and said to the students: "how, kids, do you want to know what the problem is in the last class?"

"Think clearly." "It should be about." "This class can climb up." The students gave positive answers one after another.

Mr. Xu laughed and seemed very pleased to pour a mouthful of wine: "very good, you are so confident. If it is true, I should really look at you with a new look. Then we will stop talking and start training in your simulation cabin."

With teacher Xu's permission, the students rushed to their respective simulators. Chen Feng is also the same, quickly opened the hatch, fixed the body, call out the console, Chen Feng piloted the mecha once again appeared at the start of the test project.

After the last simulation class, Chen Feng discussed with Hong shuibin and Zheng Zhirong for a long time, focusing on the different effects of using thrusters at different heights and pressures of mecha, and the power consumption under different conditions. If you can master these key consumption data and use them flexibly, it is absolutely impossible to reach the top of the mountain in half an hour.

So Chen Feng this time appeared in the starting point, and did not go to the end as usual, but in situ test the use of thrusters in various environments.

Chen Feng first started the thruster to continuously raise the body, and found an interesting rule. After every 500 meters of ascent, the ascent speed brought by the thruster will drop by 10%. After reaching the altitude of 5000 meters, it is difficult to climb any more by relying on the propeller of the mecha itself. The ascending speed can be seen by naked eyes. It can be described as turtle climbing, and it can be estimated that the maximum speed can reach 5500 meters It's the limit.

"No wonder the last time I turned on the maximum power of the thruster when I was approaching the peak, but the mecha didn't get much rise. The original problem is here. I have to keep it in mind in the future." Chen Feng confirmed a problem, firmly memorized it before trying another guess.

Chen Feng tested the power consumption of thrusters at different altitudes. After several successive liftings and landings, the results also gradually appeared in Chen Feng's mind: "it's really interesting that the efficiency and consumption of thrusters are so similar. Similarly, taking the 500m as the boundary, the power consumption of the thruster will increase by 30% for every 500m rise of mecha %When the limit of 5000-5500 meters is reached, the power consumption is three times that of the origin. "

After these tests, Chen Feng controls the remaining power of the mecha. Chen Feng uses the remaining power to turn on the thruster to assist the mecha to slow down the control speed, and finally relies on gliding to return to the starting point.

After quitting the training voluntarily, Chen Feng closed the simulation cabin and summed up her experience: "so it was very unwise for me to choose to fully open the thruster on the hillside and at the top of the mountain last time. The role and consumption of the propeller itself is a very large inverse ratio under the change of altitude. In high altitude, I have to focus on the control of the mecha itself."

So there's only one last question left. Obviously, Mr. Xu used thrusters to show all the students how to operate. But why did he still have so much residual power when he finally reached the top of the mountain?

For this problem, Chen Feng has no clue. She can only control the mecha to the end and pay attention to the remaining electricity, hoping to find something strange from it.

During the running, the power consumption of mecha has been very stable, but the emperor did not fail. Until Chen Feng turned on the thruster and let the mecha fly through the muddy road, the electric power dropped sharply, which made Chen Feng feel a little strange.In the next section of the road, Chen Feng began to use thrusters to assist the mecha to run. After passing through several potholes, Chen Feng saw that the mecha only consumed less than 10% more electricity than when running without thrusters. Finally, one thing was determined: the power consumption of small power and multi interval thrusters was very small, even negligible.

This is a major discovery. It means that Chen Feng can use thrusters to increase the stability and speed of the mecha. However, Chen Feng needs to spend more time on the use of thrusters. However, Chen Feng does not feel too uncomfortable in the aspect of distraction and multi-purpose. She feels that she can switch on and off the thrusters at any time while controlling the mecha No difficulty.

By now, all the problems that bothered Chen Feng have been solved. The next step is to move forward at full speed without any scruples. The second half of the journey has become relaxed and casual. Chen Feng constantly practices using thrusters to assist the mecha to arrive at the top of the mountain successfully. She calls out the operation console to check the results: "31 minutes! It's close to the goal of half an hour. If you don't always pay attention to the remaining power before, you should be able to succeed. Then you can be more proficient in the operation of thrusters and consume less time. "
