Teacher Xu took a sip of wine to moisten his throat, and the operation console switched to the interface of 5 mecha climbing to the top on the screen, and stretched out his hand to point to the explanation: "Judging from all your previous exercises, the five people who reached the top of the mountain the fastest were Pan Yuguo, Murong Xuan, Shui Hongbin, Nangong Mengdie and Zheng Zhirong, and the fastest Pan Yuguo also took thirty-five minutes. There are a lot of gaps between you and them, but do you think a few of them are not convinced? ”

Chen Feng carefully watched the time it took everyone, Murong Xuan only took half a minute more than Pan Yuguo, Hong Hung Bin took thirty-eight minutes, Nangong Mengdie thirty-nine minutes, and Zheng Zhirong forty minutes.

Chen Feng congratulated Shui Bin beside him: "You can be on the waterfront, how did you do it in thirty-eight minutes?" ”

"That's because I thought I could do something with thrusters from the beginning~ I'm not targeting anyone in terms of improvisation, what are all of you here~ But Pan Yuguo and Murong Xuan are really powerful, I have no clue at all to shorten the three-minute gap, Chen Feng, will the difference in synchronization rate have a big impact on this training?"

Chen Feng tilted his head and thought about it, and denied Hong Hongbin's thoughts: "I don't think so, if our synchronization rate can't meet Teacher Xu's requirements, why does Teacher Xu let us do this training?" And Mr. Xu's operation just now didn't highlight the role of high synchronization rate, right? ”

Hong Hung Bin didn't say much after listening to Teacher Xu's words, and the other students all looked at the top five in this training after listening to Teacher Xu's words, and saw that they didn't have any intention of refutating, and they all thought about something silently. There was no weighty leader to command, and the voice questioning Teacher Xu gradually subsided, and there was an eerie silence in the classroom.

Teacher Xu calmly lay back in the teacher's chair, raised his hands and rubbed his eyebrows to interrupt the rare silence: "That's all for today, it's a waste of time to continue meaningless exercises, you all go back and think about it first, and think about how to operate to shorten the time." After Mr. Xu finished speaking, he ignored the crowd and poured himself wine, and after a while, he was drunk and collapsed on the console.

The situation has been like this, and there is no point in continuing to stay in the classroom, Chen Feng and Hong Shui Bin walked to the playground and sat down, looking at the blue sky and white clouds to discuss the experience of this class.

"Shui Bin, since you tried to use the thruster at the beginning, then you must have felt more deeply when you saw Teacher Xu's operation, tell me about it." Chen Feng couldn't let go of the content of the simulation class, and urged Hong Shui Bin to quickly explain his experience.

Hong Shui Bin put his hands behind his head and lay down, and said leisurely: "In addition to the thruster skills used in short flights, the timing and strength of using thrusters when running is more difficult to master, and you will find out when you use thrusters later." ”

"Yes, you can't expect to use thrusters to accelerate during running, thrusters can only be used to assist when rushing, and they must be turned on and off in a small area, otherwise it is easy to affect the movement trajectory of the mecha itself and it will be slower." Chen Feng said what he thought in one go, and transformed the experience in the practice into words and experienced it a deeper level.

"Are you here, discussing the content of the afternoon class? Take me with you. While the two were talking, a voice came from far and near, and the two turned their heads to see Zheng Zhirong striding over, shouting as they ran: "I have a lot of questions, let's discuss it together." ”

Zheng Zhirong is kind-hearted and can afford to joke, Chen Feng and Hong Shui Bin like this classmate very much, and beckoned him to lie on the playground together and said it again.

"Chen Feng, what you said is so right, I thought about it for a long time, but I couldn't think of how to explain it clearly. And have you noticed that the power consumption of the thrusters seems to be different at different powers? Zheng Zhirong was so happy, Chen Feng immediately explained a problem he was entangled in, and this trip was not in vain.

"The power consumption of the thruster changes with the amount of power used, the more power you turn on, the higher the power consumption, and this increase ratio is not linear but jumping, the power consumption of the highest power is more than 1,000 times the lowest power after my test." Hong Hung Bin also discovered and tested the consumption of the thruster, and immediately answered Zheng Zhirong's question, and even Chen Feng opened with the mouth.

Chen Feng thought of his own flight experience near the top of the mountain, and then threw out a point: "Shui Bin, you reminded me by saying this, I don't know if you have found out." And I've flown briefly with the thrusters at the bottom of the mountain, halfway up the mountain, and near the top of the mountain, but the effect is markedly different. ”

Hong Shui Bin was very surprised, what Chen Feng said was exactly what he missed in the practice, and asked curiously: "Is there a difference?" I only flew with a thruster halfway up the mountain, and then I didn't continue to do this considering the consumption of power, Chen Feng, you have good power control, and you can fly in three places. Later, Zheng Zhirong pricked up his ears, for fear of missing every word.

"That's because I didn't use the thruster before, and I saved a lot of power by running, which is not worth mentioning." Chen Feng waved his hand, without the slightest smugness: "When the height is higher, the higher the power consumption of the thruster, and the lower the use efficiency." Even when I was close to the top of the mountain, I wanted to rely on the thrusters to force my flight, but I turned on all the thrusters of the mech and flew for a few minutes at maximum power before ascending 300 meters, and these 300 meters alone cost 5% of the power, which is not as good as the effect of opening a few thrusters on land. ”

Zheng Zhirong couldn't bear the excitement in his heart when he heard this, jumped up from the ground, spun around like an ant on a hot pot and threw out a bomb: "Yes, yes, yes!" I didn't see any problems with the flight, but it happened the same when climbing. ”

"What?! Even climbing? Chen Feng and Hong Shui Bin asked each other in unison, Zheng Zhirong said the details that were ignored by both of them, fortunately he did not refuse him to join the discussion, otherwise he would definitely fall big in the future.

"You didn't even notice? Haha, I've done a great job. Seeing that he had discovered a key point that others had not discovered, Zheng Zhirong was not in a hurry now, and he was happy to show his qigong.

Flood Bin jumped up and overthrew Zheng Zhirong to the ground, pressing him to make a threat: "If you find anything, say it quickly, otherwise I will strangle you~"

"I said, I can't do it." Zheng Zhirong raised his hand to make a surrender form, and said what happened to him: "Because our mecha was low on power at the beginning, I have been paying attention to its changes. The cost has been stable from the starting point to the bottom of the mountain, but as you climb to the top of the mountain, the higher the altitude, the faster the power will change, and I suspect that the power consumption of the mech will increase with the stronger the external pressure. ”
