Although Su Feng found inspiration from the YF120 variable engine and ACE adaptive cycle engine developed by General Dynamics of the United States, the ACE adaptive cycle engine is also a conceptual engine in General Dynamics.

Without the support of the most critical basic materials, even the ACE adaptive cycle engine, which has a lower technology content than the WS-20 'Sunny 'Aero Engine', has to wait quietly on the drawing board and cannot appear in the world.

Hearing Su Feng's low tone, Luo Hai quietly looked at the WS-20 'Jiaoyang' adaptive cycle variable aviation vector engine in Su Feng's hand, and said firmly: "Grandpa Su, one day we will develop it." ”

"Hehe, yes, as long as I, a bad old man, can witness the advent of this aero engine with my own eyes, I will be satisfied, and I can also look under the Nine Springs." When Su Feng heard this, he put the book recording the aero engine back in his backpack, and a kind smile appeared on his face.

"Grandpa Su, I'm also interested in this aspect, can you lend me those two books?" Luo Hai smiled, and then asked Su Feng.

Su Feng shook his head again and again: "No, this is my old man's daily fun." However, it is okay if you make a photocopy. ”

"Hey, that's good." Luo Hai smiled at Su Feng, and then chatted with Su Feng again: "Grandpa Su, what is the situation with the J-20?" ”

For the first fourth-generation heavy stealth fighter in China, Luo Hai is also extremely concerned.

Su Feng shook his head: "I've been retired for 2 years. I don't know much about this situation, and even if I do, I can't say that the confidentiality level of the relevant personnel has been raised to B10. ”

Two years after his retirement, he didn't know much about the J-20.

"Hmm." Hearing Su Feng's words, Luo Hai couldn't help but nodded, not paying too much attention to it.

"Xiaohai, since you are very interested in aerodynamics and aero engines, do you have any ideas to learn from me?" At this moment, Su Feng suddenly spoke up and looked at Luo Hai with a smile.

Airplanes! - Hearing Su Feng's words, Luo Hai's mind shook suddenly, and he looked at Su Feng incredulously.

He didn't expect that Su Feng, who was involved in aerodynamics and aero engines in front of him, would want to accept him as an apprentice.

Looking at Luo Hai's eyes, Su Feng smiled slightly and nodded slightly.

"Teacher."

Looking at Su Feng's smile, Luo Hai took a few deep breaths, put down the tactical military tablet in his hand, stood up and saluted Su Feng.

Scholars must have teachers, and teachers will preach and receive karma to solve doubts.

Learn it, respect and filial piety!

Su Feng smiled slightly, and smiled at Luo Hai: "Okay, haha, I didn't expect that I, Su Feng, would be able to receive such a talented good apprentice when I came to Zhuhai." ”

Luo Hai didn't speak, but he was grateful to Su Feng for his acceptance, you must know the person in front of him, but the old experts who have studied in the two professional disciplines of aerodynamics and aero engines for decades, and the academicians of the Chinese Academy of Sciences can't even compare to Su Feng in this regard!

Su Feng smiled on his face, took out the two books just now from his backpack, and put them in Luo Hai's hand: "Xiaohai, you take these two books." ”

"Teacher, this is too precious." Luo Hai saw Su Feng handing over these two extremely precious books, and immediately spoke.

He could see that these two books were like Su Feng's heart.

"You are my youngest apprentice, and there are three senior brothers in front of you, so these two books should be lent to you by me." Su Feng's face was covered with a warm smile, he shook his head and smiled, and stuffed the two books into Luo Hai's arms.

Looking at the two books in his arms, Luo Hai was moved in his heart, smiled, and thanked Su Feng with great respect: "Thank you, Master." ”

"Well, no more talk." Su Feng shook his head.

Luo Hai gently put away the two books, recorded his contact information and address with pen and paper, put it to Su Feng, and said, "Master, this is my contact information and address, as well as the IP number. I'm out on vacation during this time, and I'm going back to the base in a few days, how can we get in touch in the future? ”

"It's okay, isn't there a distance e-school? Anyway, we need to calculate in this business, and it's very boring. If there's anything you don't understand, just ask me. Su Feng took the note handed by Luo Hai and said after putting it away.

Luo Hai nodded, and then began to chat with Su Feng again, learning Su Feng's address and other basic information.

Time passed slowly, and Su Feng, who became Luo Hai's master, took advantage of the current time to explain the theoretical knowledge of aerodynamics and aero engines to Luo Hai.

Luo Hai, who had developed his brain by his ability, quickly recorded the theoretical knowledge explained by Su Feng, and at the same time, based on his understanding of aerodynamics and aero engines, he drew inferences from one case and used it flexibly, and quickly integrated the knowledge explained by Su Feng into his own things.

Next to the two seats, a stack of scratch paper was piled up in half an hour.

"Yes, yes, the talent is really high." Su Feng looked at Luo Hai, who quickly understood what he had explained, and nodded with satisfaction.

At this moment, Li Zheng, who was wearing a suit and leather shoes, suddenly came here, stood below and shouted to Luo Hai, who had entered the state of studying: "Old Luo, Teacher Weng is looking for you." ”

After sending several messages to Luo Hai's tactical military tablet and not responding, in desperation, Weng Tianping had to use the positioning device of the tactical military tablet to find Luo Hai's location with his own authority.

And Li Zheng was sent to call Luo Hai.

It's just that Luo Hai, who entered the state of learning, ignored Li Zheng.

Hearing Li Zheng's words, Su Feng, who was sitting next to him, couldn't help but shake his head when he looked at Luo Hai, who seemed to be obsessed, and gently patted Luo Hai's shoulder twice.

"Huh? Master, what's the matter? Luo Hai, who was thinking about a question, was stunned for a moment after being interrupted by Su Feng, and then asked.

Su Feng looked at Luo Hai's appearance, and said with a smile on his face: "Xiao Hai, it seems that your companion is looking for you." After speaking, he pointed to Li Zheng, who was wearing a suit and leather shoes under the stage.

Luo Hai looked in the direction of Su Feng's finger, and when he saw Li Zheng in the audience, he immediately responded: "It turned out to be Lao Li." ”

"Lao Luo, Teacher Weng is looking for you." Li Zheng reminded loudly again.

Hearing Li Zheng's words, Luo Hai reacted, looked at Li Zheng, and looked at Su Feng: "Master, I ......"

"Go ahead, we've already communicated anyway, and then distance education will be fine. Remember that I can just come and see the old man if I have nothing to do, it's not too early, I have something to do next. ”

Su Feng said with a smile, interrupting Luo Hai and not embarrassing him.

"Thank you, master." When Luo Hai, who was in distress, heard this, his heart couldn't help but relax, he saluted Su Feng respectfully, took the tactical military tablet and two books, packed up the scratch paper, and then left under Su Feng's gaze.

Su Feng re-grasped the SLR camera, his face full of traces of time was red, and he was full of smiles: "This little guy, if those old guys knew that I had accepted an apprentice who was an ace pilot and had a high talent, what would their expressions be?" ”

Thinking of this, Su Feng couldn't help but hum, holding a single-lens reflex camera to photograph the conceptual aircraft and active fighter jets of various countries in the Zhuhai Air Show.

After the J-10B canard wing fighter and the F-35A stealth fighter duel, in order not to make the air show cold, the air show teams of various countries also began to perform, and the unique voice of the male host and the voice of the special guest Professor Wu also sounded quickly.

The Zhuhai Airshow on the third day is wonderful and indescribable.

Luo Hai left with a tactical military tablet, scratch paper, and two books, joined Li Zheng, and then walked towards the military viewing area.

On the way, Li Zheng looked at Su Feng who was holding a single-lens reflex camera, and asked softly: "Lao Luo, who is that old man?" It looks so familiar. ”

"Domestic aviation experts, I just have a few questions, let me ask." Luo Hai smiled slightly.

Li Zheng heard Luo Hai's words, thought for a while, and was suddenly surprised: "Yes, I remembered, Lao Luo, is his name Su Feng?" ”
