Chen Fei's behavior surprised Yuan Lang and Gao Cheng. The two looked at each other in surprise, and then looked at Chen Fei together, but they didn't say anything. So the three of them visited with great interest under the leadership of Jiang Haitao
Got up.
At the beginning of the visit, Chen Fei didn't say much, he just observed calmly.
Jiang Haitao is not a very talkative person. If there is no need to speak, he will remain silent. But if anyone asks a question, even if it is very amateur, he will answer it seriously. In short
, Chen Fei felt that he was a serious person, a guy who didn't like to show off, and was not very good at socializing. He was a standard man in science and engineering. After getting to know him silently for a while, Chen Fei's impression of Jiang Haitao improved a lot.
Later, when Yuan Lang and Gao Cheng went to inspect another place, Chen Fei and Jiang Haitao were alone together. Jiang Haitao was a little at a loss and didn't know what to do. Chen Fei glanced at him and took the opportunity to chat.
"Where is Xiao Jiang from?" Chen Fei took the initiative to start the topic.
"XX." Jiang Haitao replied seriously.
"XX is a good place. The grapes there are good, big and sweet." Chen Fei naturally praised Jiang Haitao's hometown. When Jiang Haitao heard this, his eyes lit up and he felt much better about Chen Fei.
In fact, Chen Fei has never been to Jiang Haitao's hometown, but he has been online a lot and heard a lot of things from hearsay, and he still basically remembers the geography knowledge of middle and high school, so he can talk about it endlessly. In fact, Chen Fei may not necessarily be talking about it.
Accurate, but even if he said it wrong, Jiang Haitao wouldn't take it to heart because Chen Fei said nothing but compliments. Even if he said it 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 flown?" Chen Fei asked.
"Zhi-8, Zhi-8s, Zhi-8A, Zhi-8J..." Jiang Haitao said slowly.
Chen Fei discovered that Jiang Haitao had flown many types of aircraft, including domestic ones, imported ones, Russian and French ones, and aircraft models from many countries. However, relatively speaking, the one he flew the most was the Z-8A. Therefore,
Chen Fei's heart moved and he couldn't help but ask: "Xiao Jiang, you have flown so many Z-8A sorties, how did you overcome the design flaw of the Z-8A main oil temperature alarm system."
Um?
Jiang Haitao suddenly raised his head and looked at Chen Fei in surprise.
The Z-8 is an old model. To be honest, many young pilots nowadays have never flown this aircraft. Today’s young pilots either start directly from the Z-9, or fly Lao Maozi’s Mi-171, or other
, there are very few people who use Fem 8 for a long time, as for the straight 8A
, then even less. Therefore, the question raised by Chen Fei has never been heard of by today's young pilots, but Chen Fei not only mentioned it, but also very accurately. This shows that he is a veteran of flying Z-8, otherwise he would not be able to mention it.
Such a problem arises.
The Z-8A is currently the heaviest heavy-duty helicopter with a maximum take-off weight of 13,500 kilograms, so its main reducer has a very powerful power of 3,000 kw. In order to effectively monitor the operation of the main reducer, engineers designed a main reducer.
Lubricating oil temperature alarm system, but this system has design flaws, so it often falsely alarms or does not alarm, seriously affecting the aircraft's integrity rate and flight training.
However, some experienced pilots will solve this problem by themselves. Of course, each has its own unique tricks. Now, manufacturers have also provided corresponding technical solutions, but they are still not perfect, so some experienced pilots still like to solve it by themselves.
Therefore, the question raised by Chen Fei is not only sharp, but also tricky.
Jiang Haitao stared at Chen Fei blankly for a while - usually, pilots with a little bit of discernment would not look directly at their leader like this, but Jiang Haitao did just that - he looked blankly at Chen Fei
Fei kept going for a while and then said:
"Chief, the oil temperature indicator and the oil temperature sensor are series voltage dividing circuits. When the power supply voltage increases, the divided voltage on the temperature sensor at the same temperature increases, so an early alarm occurs. When the power supply voltage drops
When the voltage increases, the partial voltage decreases, resulting in a delayed alarm or no alarm, so if you want to improve this problem, it is very simple, just eliminate the influence of the power supply voltage."
Jiang Haitao is not as eloquent as Chen Fei, but he still made this issue clear.
Chen Fei listened and nodded. He basically had a rough understanding of Jiang Haitao's abilities.
Jiang Haitao looked at Chen Fei in surprise, with a look of confusion. At this moment, Chen Fei suddenly asked without warning: "I heard that you are good at helicopter air combat, can you give me some advice?"
A dynamic model of helicopter air combat?”
ah?
Jiang Haitao was stunned.
"If it's difficult, forget it!" Chen Fei stood up quickly when he saw Yuan Lang and Gao Cheng walking over.
"Chief, I can do it!" Jiang Haitao finally reacted and said hurriedly: "Chief, there are mature and classic methods for modeling the helicopter dynamic system, so it is not difficult. For example, it can be used when studying the flight characteristics of helicopters.
Linear small perturbation equations, and the development of six-degree-of-freedom full nonlinear equations used in full-mission flight simulators.
However, the current small disturbance equation focuses on local flight performance analysis, which is difficult to reflect the entire flight quality of the helicopter, and the input quantity cannot be expressed explicitly. The six-degree-of-freedom full nonlinear equation is a set of high-order differential equations, which is difficult to solve in high-level calculations.
The amount of calculation is large when calculating the order combination equation, and several aerodynamic parameters and torque coefficients need to be interpolated, which will inevitably require longer calculation time."
Jiang Haitao stuttered a bit when he first started speaking, but gradually, he found that Chen Fei listened very carefully and seemed to understand. He couldn't help but gradually became more fluent. At the end, there was even a trace of desire to express himself.
However, just when he was about to start a long speech, Chen Fei stopped him with his hand: "Okay, the brigade commander is here, let's stop talking today!"
Jiang Haitao felt a sense of loss.
In fact, Chen Fei already took a fancy to Jiang Haitao, but he was not busy making a decision. He observed silently for a while, but he didn't say anything more before leaving.
After inspecting the base of the air assault brigade that day, Chen Fei, Yuan Lang, and Gao Cheng went to the military compound, where they met with the leaders and reported on relevant work and ideas for the future.
That night, Yuan Lang returned home, while Chen Fei and Gao Cheng slept together in the guest house of the military region. Gao Cheng didn't want to go home, so he called his wife and told him that he had to work overtime and was busy here. Chen Fei was still there.
He told a few lies for help, so that night, the two of them slept in the guest house of the military area, but the second
They parted ways early the next morning. Gao Cheng went to do his business, while Chen Fei went to Jiang Haitao's old army, transferred his file and studied it carefully. After reading it, he didn't say anything and went directly to Yuan Lang.
, said seriously: "Brigadier Commander, I want to transfer Jiang Haitao to our air assault brigade as a flight combat training instructor!"
