The plane began to descend shortly after taking off from Zhoushan, and Gan Yongxing's first stop was Songjiang, which at that time was already the largest ship supplier to the Imperial Navy, so Gan Yongxing would start here. After Gan Yongxing got off the plane, the transport plane took off again and flew directly to Harbin with Tan Renhao.

On the plane, Tan Renhao and Gan Yongxing had a brief chat, and they didn't talk about anything important, probably Gan Yongxing was also a little tired. After the plane took off again, Tan Renhao was very much like sleeping, but thinking of the few books he had just "borrowed" from his father-in-law, he decided to seize the time to supplement his knowledge first, and then consider the issue of rest.

Liao Hanxiang gave Tan Renhao several very in-depth technical books, which also reflected the skills of Liao Hanxiang, a regular aviation general. These books are all books about the structure of airplanes, and the principles of airplanes. At first, Tan Renhao didn't understand what Liao Hanxiang asked him to do with these books, and he thought that Du Xing had taken the wrong book. After Du Xing proved that these were the books that Liao Hanxiang told him, and he didn't find any other books with the same title, Tan Renhao didn't ask much. And it wasn't until Tan Renhao finished reading a few main chapters that he understood. If you want to thoroughly grasp the cost of aircraft manufacturing, then you must first start with the basic structure of the aircraft, and this is Tan Renhao's imperfect knowledge.

The basic principles of the aircraft are not much to say, although the scientists at that time did not study aerodynamics thoroughly, but the basic principles of the aircraft were still understood. In terms of aircraft structure, to put it thoroughly, it is a power system installed. It's just a machine that can fly on its own power! This was the basic structure of the early aircraft, but later it became more demanding. And the pursuit of performance, so the result is more complex aircraft.

Fundamentally, the aircraft was divided into engines. The fuselage, wings, take-off and landing system, and the operating system are three parts, and there may be other parts of the aircraft with different purposes. But basically, these five parts are indispensable to any aircraft. Similarly, these five parts are composed of many parts, or subsystems, for example, a 22-cylinder engine may have thousands of parts, and only when these thousands of parts work normally at the same time, the engine can work normally and reach the best condition. The airframe of the aircraft includes subsystems such as the main load-bearing structure, skin, and branching structure. Each subsystem itself is made up of multiple parts. The same goes for the rest of the plane, so that an airplane is made up of thousands, if not tens of thousands, of parts. Only when these parts are in working order can the aircraft fly safely and be effective in combat.

While these parts make up the aircraft, they also incur the manufacturing cost of the aircraft. It is as large as several meters long on the plane. Even the main skeleton of tens of meters, the cylinder block of the engine, as small as a screw, all the parts have a price, and these prices are accumulated, and then add the labor cost of the workers, this is the cost of an aircraft. Of course, in the manufacturing process, there will definitely be wastage. and scrap, which must also be counted.

After understanding the structure of the aircraft. Tan Renhao finally figured out why a fighter plane could easily cost hundreds of thousands, which was enough to withstand a year's allowance for an admiral. In fact, the price of local aircraft was still quite cheap at that time, and after entering the jet age, especially after the birth of electronic technology, the price of aircraft was called sky-high. However, for the mass production of thousands or tens of thousands of planes at every turn, if the price of an aircraft can be reduced by 10,000 yuan, the production of 10,000 aircraft can save 100 million yuan in procurement funds, which is not a small amount of money.

Tan Renhao didn't have time to carefully study those technical details, he just looked for the parts he needed to read, but when the plane arrived in Harbin, he had only finished reading the main sections of the two books, and there were three books left next to him and not turned over. This also made Tan Renhao feel that time flies quickly, maybe in the future, when taking the plane, he can bring a few books, so he doesn't need to sleep on the plane to pass the time.

"General Tan, welcome to the Harbin Aircraft Factory, how are you doing along the way?"

"Yes, this plane is also where you make it, right?" Tan Renhao glanced at the middle-aged man who came to greet him, and then looked at the transport plane that had just stopped behind him, he was deliberately pretending to be confused, because all the navy's transport planes were produced by Nanfei.

"This ......," the middle-aged man smiled awkwardly, "We are preparing to invest in the construction of a transport aircraft production line, and we will definitely provide General Tan with a luxury special plane at that time!" ”

"I don't have that!" Tan Renhao's answer was a little lukewarm, in fact, the plane behind him was Gan Yongxing's special plane, and only the marshal and the chief of the general staff had separate special planes in the imperial navy, and the other so-called special planes were actually used by the generals on a rotational basis, and whoever needed them would use them, without stipulating which one would be used by which general.

"Talking about the general, you are too humble, to talk about the general's current achievements, I'm afraid it will ......"

"By the way, may I ask you ......?"

"Ah, General Tan smiled." The man remembered that he hadn't introduced himself yet. "Under the surname Gong, the name is Jian, the healthy Jian, is the director of the Foreign Affairs Department of Hafei."

"Foreign Affairs?" This person's name reminded Tan Renhao of a weapon in the era of cold weapons.

"It's dedicated to receiving important people." Gong Jian didn't tell the truth, in fact, most of the people he received were non-important people.

Tan Renhao nodded, he had already walked to the car. This should be somewhat similar to the director of the Navy's guest house, and in a private company, it should be called a "business office". But no matter what the name is, the thing should be the same.

"Please, talk about the general, please!" Gong Jian's reaction was a little sluggish, which Tan Renhao had already seen.

After the car started, Gong Jian asked the driver to go directly to the hotel.

"It was supposed to be our general manager, but the preparations for the production of the new fighter have been very troublesome recently, and the general manager has been busy over there, so I would like to ask the general for forgiveness."

"It's better to be busy with business than to be idle. I can understand that. Tan Renhao smiled and nodded, he didn't believe Gong Jian's words. If the general manager of a large factory with more than 100,000 workers wants to go to the production line, will anyone believe this? Even if it is true, then this only says one thing. That is, the management order is very chaotic. This is like Marshal Nie Renfeng running to Midway Island to command the team to attack the Hawaiian Islands, which is unbelievable.

"In the evening, we prepared a light dinner, and the general manager will come to visit General Tan in the afternoon."

"I don't think it's necessary." Tan Renhao didn't want to get too close to these people who looked like they were stained with the smell of copper, "Just send me to the Navy Office, we've already contacted them." I was given a place to stay. As for eating, when things are done, I should invite you, right? ”

"General Tan, you're too polite, and we've prepared a room for you at the hotel......"

"Go to the Navy Office, Mr. Gong, you should know the rules of the Navy, it's a time of war, it's safer to live there. Don't you say? ”

"This ......" Gong Jian hesitated for a moment, and then let the driver change the route. General Tan, you must come to this dinner in the evening, I will pick you up in the evening, our general manager is also ready to exchange opinions with General Tan on this negotiation first, so that we can start the relevant work as soon as possible. ”

It's not good to talk about Renhao and refuse again. He could only say, "Okay, then I'll go by myself at night, and you can tell my adjutant later, so that he knows how to drive." ”

"This ......"

"Mr. Gong, we soldiers have the style of doing things in a military manner, please understand."

"Of course, of course, we can totally understand that."

Tan Renhao didn't bother to talk to Gong Jian anymore, his eyes were half-closed. Pretending to be nourishing. Gong Jian didn't bother talking about Ren Hao anymore, at least for a few minutes. He already knew that Tan Renhao was a soldier who was not easy to deal with.

Soon, the car stopped outside the Navy reception office, in fact, this is the Navy guest house in Hafei, because there have been naval officers here for a long time, so it is necessary to set up a guest house. The person in charge of the guest house had already received the news and prepared a room for Tan Renhao. This is the best room, but it is quite simple, at least in Tan Renhao's opinion, it is far worse than the navy's guest houses in several big cities, and even worse than those luxury hotels. At that time, Harbin was not a big city, and Hafei was in the suburbs, so the conditions here were even more rudimentary.

"Brother Tan, why don't you go to the hotel?" Du Xing felt that Tan Renhao was a little aggrieved.

"Why do you want to stay in a hotel?" Tan Renhao glanced at the adjutant, "You have to remember one thing, eat people with a soft mouth and take people short, this time we are here to negotiate with Ha Fei, not to travel at public expense." ”

Duchenne stuck out his tongue, knowing that he had said the wrong thing at the beginning.

"Prepare a regular dress for me, don't be too grand, tonight is not a formal occasion, there is no need to dress too formally."

Duchenne took back the military dress he had just taken out, and then took out a set of regular clothes. Because it was packed in a duffel bag, the clothes were already a little wrinkled. Without asking, Duchenne decided to send his clothes to the laundry room for ironing, only to find out that there was no laundry room at all, only irons.

Tan Renhao hurried to sleep for a few hours, he didn't rest on the way, and he didn't sleep all night, and now he is very tired. When he was woken up by the sound of the brakes of the car outside, he found that the military uniform, which had been as smooth as new, was placed on the back of the seat next to the head of the bed.

"Talking about big brother, it seems that people from the aircraft factory are here, there are more than a dozen, and it seems that they are not ordinary people."

Tan Renhao was stunned for a moment, then walked to the window, and sure enough, more than a dozen people walked into the small garden of the office, all wearing standard short Tang clothes, and at a glance, they knew that they were all hand-cut expensive clothes.

"How do you know they're the big guys?" Tan Renhao was very surprised by Duchenne's vision.

"Look at the clothes, the way they walk, and the way people around them look at them."

"Who did you learn this from?" Tan Renhao was even more curious, as far as he knew, when Du Xingcai was with him, he was still stunned and didn't understand anything.

Duchenne smiled awkwardly. "It's not like it's been practiced over time."

"Yes, if you kid had half the heart in learning skills from other places, then you wouldn't be a captain officer now."

Du Xing scratched his scalp, he didn't want to be promoted anymore, unless Tan Renhao was promoted to general, he would have a chance to become a major, because most of the adjutants of the current serving generals were major officers, and Marshal Nie Renfeng's adjutant was even promoted to colonel not long ago. Although the rank of adjutant is only linked to his allowance to a large extent, or to say that he looks better when he goes out, for Duchen, if he wants to stay with Tan Renhao, then he has to endure the current treatment.

When Tan Renhao put on his military uniform, footsteps were heard in the corridor. He looked at himself in the mirror for the last time, and after thinking that there was no problem, he walked towards the door, and when Tan Renhao opened the door, Gong Jian was about to knock on the door, and behind him, there was a middle-aged man of about 45 years old.

"This is General Tan!" The middle-aged man must have recognized the rank of lieutenant general on Tan Renhao's shoulder, "Under Feng Xiangchu, the general manager of the Harbin Aircraft Factory!" ”

"I have admired Mr. Feng's name for a long time, but I didn't expect that Mr. Feng is so young!"

"The general has won the award, Feng is just a civilian, and he is not worthy of the general's praise." Feng Xiangchu shook hands with Tan Renhao with a smile, "If General Tan is ready, then let's talk on the road!" ”

Tan Renhao nodded and followed Feng Xiangchu downstairs, of course, he didn't forget to let Du Xing follow.

Feng Xiangchu's father is the famous Feng Ru, the first aviator in the world to fly into the sky, at least, the imperial side thinks so, because Feng Ru only flew into the sky a little earlier than the Wright brothers in the United States, and the United States insists that the Wright brothers were the first to complete the flight, and they have relevant evidence in their hands, and Feng Ru had no evidence when he flew at that time, and there were not even a few witnesses. Of course, this argument is not important, whether it is Feng Ru or the Wright brothers, they are both pioneers of aviators and worthy of respect.

Tan Renhao still knows Feng Xiangchu's background well, at least he thinks so. Therefore, Tan Renhao inevitably observed Feng Xiangchu, a middle-aged man, and wanted to know how this middle-aged man realized his father's unfulfilled dream.
