Soldier Assault Commander

Chapter 430 Investigation
430 inspection
Fade Chen's behavior surprised Yuan Lang and Gao Cheng. The two looked at each other in surprise, and then looked at Fade Chen together, but they didn't say anything. So the three of them, led by Jiang Haitao, visited with great interest. up.

At the beginning of the visit, Fade Chen didn't say much, but just observed calmly.

Jiang Haitao is not a very talkative person. If there is no need to speak, he will remain silent all the time, but if someone asks a question, even if it is very amateurish, he will answer it seriously. Fade Chen felt that he was a serious person, he didn't like to stand out, and he was not very good at socializing.

In the back, when Yuan Lang and Gao Cheng went to inspect another place together, Fade Chen and Jiang Haitao stayed together alone. Jiang Haitao was a little at a loss and didn't know what to do. Fade Chen glanced at him and took the opportunity to chat.

"Where is Xiao Jiang from?" Fade Chen took the initiative to change the topic.

"XX." Jiang Haitao answered solemnly.

"XX is a good place. The grapes there are good, big and sweet." Fade Chen naturally praised Jiang Haitao's hometown.

In fact, Fade Chen has never been to Jiang Haitao’s hometown, but he has been on the Internet a lot and heard a lot of things, and he still basically remembers the geography knowledge in junior high school, so he can talk about it endlessly. In fact, what Fade Chen said is not necessarily true. Accurate, but even if he said something wrong, Jiang Haitao wouldn't take it to heart, because what Fade Chen said was praise, even if he said something wrong, Jiang Haitao wouldn't take it too seriously. After chatting like this for a while, Jiang Haitao finally calmed down a lot.

"What types of helicopters have you driven?" Fade Chen asked.

"Zhi-8, Zhi-8s, Zhi-8A, Zhi-8J" Jiang Haitao said in a leisurely manner.

Fade Chen discovered that Jiang Haitao has flown many aircraft types, domestic imported ones, Russian military ones, French ones, and aircrafts from many countries. However, relatively speaking, the Z-8A is the one he has flown the most. Therefore, Fade Chen's heart moved, and he couldn't help asking: "Xiao Jiang, you have flown so many Z-8A sorties, how did you overcome the design defect of the Z-8A's main reducer oil temperature alarm system."

Ok?
Jiang Haitao raised his head and looked at Fade Chen in surprise.

The Z-8 is an old model. To be honest, many young pilots have never flown this type of aircraft. The young pilots now either start directly with the Z-9, or fly the old-fashioned Mi-171, or other , there are very few flying Mi 8 for a long time, as for Zhi 8A, there are even fewer, so the question raised by Fade Chen has never been heard by young pilots, but Fade Chen not only mentioned it, but also very accurately , it seems that he is a veteran of Feizhi 8, otherwise he would not be able to ask such a question.

Z-8A is currently the heaviest heavy-duty helicopter with a maximum take-off weight of 13500 kg, so the power of its main reducer is very large, reaching 3000kw. In order to effectively monitor the operation of the main reducer, the engineers designed the main reducer. The oil temperature alarm system for reducing lubrication, but this system has design flaws, so it often falsely alarms or does not alarm, which seriously affects the integrity rate of the aircraft and flight training.

However, some experienced pilots will solve this problem by themselves. Of course, each has its own unique skills. Now, the manufacturer has given a corresponding technical solution, but it is still not perfect, so some veteran pilots still like to solve it by themselves.

So the question Chen Fei raised was not only sharp, but also tricky.

Jiang Haitao stared blankly at Chen Fei for a long time - under normal circumstances, a pilot with a little sharp eyesight would not look directly at his leader like this, but Jiang Haitao did just that - he stared blankly at Chen Fei Fei stayed for a while before saying:
"Boss, the lubricating oil temperature indicator and the lubricating oil temperature sensor are a voltage divider circuit in series. When the power supply voltage rises, the divided voltage on the temperature sensor at the same temperature increases, so there will be an early alarm. When the power supply voltage drops When , the partial voltage decreases, so there is a lagging alarm or no alarm, so if you want to improve this problem, it is also very simple, just eliminate the influence of the power supply voltage."

Jiang Haitao was not as eloquent as Chen Fei, but he still made this issue clear.

After hearing this, Fade Chen nodded. He basically had a general understanding of Jiang Haitao's abilities.

Jiang Haitao looked at Fade Chen in surprise, with a look of ignorance. At this moment, Fade Chen suddenly asked without warning: "I heard that your helicopter air combat is good, so can you give me some advice?" A dynamic model for helicopter air combat?"

what?
Jiang Haitao was stunned.

"If it's difficult, forget it!" Fade Chen saw Yuan Lang and Gao Cheng walking over from there, and stood up quickly.

"Boss, I can do it!" Jiang Haitao finally reacted, and hurriedly said: "Boss, there are already mature classic methods for modeling the helicopter dynamics system, so it is not difficult. For example, when studying the flight characteristics of a helicopter, you can use Linear Small Disturbance Equation, the development of a six-degree-of-freedom full-scale nonlinear equation used in a full-mission flight simulator.

However, the current small disturbance equation focuses on the analysis of local flight performance, which is difficult to reflect the overall flight quality of the helicopter, and the input amount cannot be expressed explicitly, while the six-degree-of-freedom full-quantity nonlinear equation is a set of high-order differential equations. The amount of calculation is large when the first-order coupling equation is used, and some aerodynamic parameters and moment coefficients need to be interpolated, which will inevitably require longer calculation time. "

Jiang Haitao stuttered at the beginning, but gradually, he found that Fade Chen listened very carefully and seemed to understand it, so he couldn't help but gradually became more fluent, and at the end, there was even a trace of desire to express.

However, just when he was about to start a long speech, Fade Chen stopped his narration with his hand: "Okay, the brigade commander is here, let's stop here today!"

Jiang Haitao felt a sense of loss.

In fact, Fade Chen had already set his sights on Jiang Haitao, but he was not in a hurry to make a decision. He observed silently for a while, but he didn't say much before leaving.

After inspecting the Air Force Brigade's base that day, Fade Chen, Yuan Lang, and Gao Cheng went to the compound of the military region together, went there to find the leader, and reported on the relevant work and ideas about the future.

That night, Yuan Lang returned home, and Fade Chen and Gao Cheng slept together in a guest house in the military region. Gao Cheng didn't want to go home, so he called his wife and said that he was busy working overtime here, and Fade Chen was still on the sidelines. Helped to tell a few lies, so that night, the two slept in the guest house of the military region, but they parted ways early the next morning, Gao Cheng went to work on his affairs, and Chen Fei went to Jiang Haitao's old army, transferred He studied his file carefully, and after reading it, he found Yuan Lang without saying anything, and said seriously, "Brigade Commander, I want to transfer Jiang Haitao to our Air Assault Brigade as a flight combat training instructor!"
