Chapter 64

Mr. Xu took a sip of wine to moisten his throat. The operation console switched to five mecha climbing interfaces on the screen, and pointed out one by one: "judging from all your previous exercises, the five fastest to reach the top of the mountain were pan Yuguo, murongxuan, Hong shuibin, Nangong Mengdie and Zheng Zhirong, and the fastest pan Yuguo also took 35 minutes. You are far from them, but are they not satisfied? "

Chen Feng took a close look at everyone. Murongxuan only spent half a minute more than pan Yuguo, Hong shuibin spent 38 minutes, Nangong Mengdie 39 minutes, and Zheng Zhirong 40 minutes.

Chen Feng congratulated the flood bin nearby: "you can do it by waterfront. How can you do it in 38 minutes?"

"That's because at the beginning, I thought I could do some articles with thrusters. In terms of contingency, I'm not aiming at anyone. All of you here are that. But pan Yuguo and murongxuan are really good. I have no idea to shorten the three minute gap. Chen Feng, do you think the difference of synchronization rate will have a great impact on this training?"

Chen Feng tilted her head to think about it and denied Hong shuibin's idea: "I don't think so. If our synchronization rate can't meet the requirements of Mr. Xu, why should Mr. Xu let us do this training? What's more, Mr. Xu's operation did not highlight the role of high synchronization rate? "

After listening to Mr. Xu's words, the other students all looked at the top five of the training. Seeing that they didn't have any objection, they all thought about something in silence. There is no weight of the leader command, query teacher Xu's voice gradually subsided, the classroom presents a strange quiet.

Teacher Xu happily 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 practice. You all go back to think about it and think about how to shorten the time." Mr. Xu said that he did not pay attention to the public. He began to drink wine and soon collapsed on the console.

The situation has been like this. It is meaningless to continue to stay in the classroom. Chen Feng and Hong shuibin went to the playground and sat down, looking at the blue sky and white clouds, and discussing the experience of this class.

"Shuibin, since you have tried to use thruster at the beginning, you must feel more deeply when you see Mr. Xu's operation. Tell me about it." Chen Feng couldn't let go of the content of the simulation class and urged Hongshui bin to explain his experience quickly.

Hong shuibin put his hands behind his head and lay down. He said leisurely, "apart from the propeller skills used in short flight, it is more difficult to master the timing and strength of using thrusters when running. You have noticed when you use thrusters behind you."

"Yes, we can't expect to use thrusters to accelerate in the process of running. The thrusters can only be used to assist when running, and it must be opened and closed in a small area, otherwise it will easily affect the movement track of mecha itself, but it will be slower." Chen Feng said what she wanted to say, turning the experience in practice into words, which deepened her understanding.

"Are you here, are you discussing the content of the afternoon class? Take me with you. " When they were talking, a voice came from far to near. They turned their heads and saw Zheng Zhirong stride over, shouting: "I have some questions. Let's discuss them together."

Zheng Zhirong is kind-hearted and can play a joke. Chen Feng and Hongshui bin like this classmate very much. They ask him to lie on the playground and say it again.

"Chen Feng, you're right. I've been thinking for a long time, but I can't figure out how to say it clearly. And have you noticed that the power consumption of thrusters at different powers seems to be different? " Zheng Zhirong was so happy that Chen Feng gave a thorough explanation of one of his tangled problems. This trip didn't come in vain.

"The power consumption of the propeller changes with the power used. The higher the power you turn on, the higher the power consumption. Moreover, the increase ratio is not linear, but jumping. According to my test, the power consumption of the highest power is more than 1000 times of the lowest power." Hong shuibin also found and tested the consumption of thrusters, and immediately answered Zheng Zhirong's question, and Chen Fengdu immediately opened up with Mao.

Chen Feng thought of her flight experience near the peak of the mountain, and then put forward a point of view: "shuibin, your saying reminds me, I wonder if you have found it. What's more, I used thrusters to fly for a short time at the foot of the mountain, at the middle of the mountain and near the top of the mountain, but the effects of these three places are obviously different. "

Hong shuibin was very surprised. What Chen Feng said was exactly what he missed in his practice. He asked curiously, "is there any difference? I only fly with thrusters on the hillside. After that, I didn't continue to do so considering the power consumption. Chen Feng, you have a good power control. You can also fly in three places. " Later, Zheng Zhirong was even more erect ears, for fear of missing every word.

"That's because we didn't use thrusters before, and all of them saved a lot of electricity. It's not worth mentioning." Chen Feng waved her hand without any complacency: "the higher the altitude, the higher the power consumption of the propeller and the lower the efficiency. Even when I was close to the top of the mountain, I wanted to rely on the thrusters to fly up. As a result, I turned on all the thrusters in the mecha and used the maximum power to fly for a few minutes before rising 300 meters. Moreover, the 300 meters alone cost 5% of the electricity, which is not better than the effect of opening a few thrusters on the land

Hearing this, Zheng Zhirong jumped up from the ground and threw a bomb like an ant on a hot pot! Although I didn't find any problems with flying, it was the same with climbing. ""What?! Even climbing? " Chen Feng and Hong shuibin 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 surely have a big fall in the future.

"You didn't find out? Ha ha, I have done a good job. " Seeing that he has found the key points that others have not found, Zheng Zhirong is not in a hurry, and he is happy to show Qigong.

Hong shuibin jumped up and overthrew Zheng Zhirong to the ground, pressing him to make a threat: "if you find anything, please tell me quickly, or I will strangle you ~"

"I said I said it was not enough." Zheng Zhirong raised his hand to make a surrender, and said his own experience: "because our mecha was short of electricity at the beginning, so I have been paying attention to its changes. The consumption from the starting point to the foot of the mountain has been very stable, but in the process of climbing to the top of the mountain, the higher the height, the faster the frequency of power change. I doubt that under the stronger external pressure, the power consumption of mecha will increase
