Time will dilute memories, and in Qin Zhiyuan's memories, there are some things that are extremely precious. Pen, fun, pavilion www. biquge。 info

Let's not talk about civilian things, Qin Zhiyuan also loves car models, but it is useless except for adding a few classic models with a banging appearance to Lanfang Automobile Group, mainly military, such as the forward deck of the Liaoning ship, such as the duck layout of J-10 and J-20, such as the two rotors on the Chinook helicopter, which are all valuable assets in Qin Zhiyuan's memory.

In order to keep these things from being diluted by time, Qin Zhiyuan formed drawings of almost all the things he could think of, which can provide great help to Lanfang's military industry in the future, at least so that Lanfang's military industry will not take detours.

In fact, the J-20 and the Liaoning ship are a bit too far away for the current Lanfang, and even the helicopter has just begun to be studied, or it is something that is more suitable for the current stage of scientific and technological development, which can provide the greatest help to Lanfang's military industry.

So when Qin Zhiyuan came to the Aero Engine Research Institute, Qin Zhiyuan brought a model of "thunder and lightning".

The Thunderbolt, also known as the P-47, was once the best piston fighter in World War II, producing a total of 15,683 aircraft in World War II, a number that is not only unprecedented but also unprecedented, and until the 21st century, it is the most produced aircraft in the world.

On the surface, the P47 is bulky, but "bulky" means a stronger fuselage and stronger survivability, often the P47 is fine with dozens of bullets, while his enemies only need to hit a few bullets to lose their combat ability.

In the course of the entire Second World War, the P47's air combat gain and loss ratio was 4.6 to 1, that is, 4.6 enemy planes were hit, and 1 was lost by itself, and the loss rate per 1,000 sorties was only 7, which was still for the level of aircraft during World War II, and for the current aircraft, this battle loss ratio will be further expanded.

After completing the design of the new air-cooled radial engine, Long Chengyuan took a two-month vacation, went to Corsica to spend a good vacation, and now just returned to Lanfang, just saw the model of the P47, Long Chengyuan's reaction is the same as many people: "God, it's really ugly, Your Majesty, did you drink too much to make this model?" ”

Because of the relationship between Long Chengyuan and Mixia, Long Chengyuan is equivalent to Qin Zhiyuan's brother-in-law, so Long Chengyuan is not much afraid of Qin Zhiyuan, and he talks very casually.

This kind of "casual" attitude also makes Qin Zhiyuan feel more comfortable than "restrained respect", coupled with the value of Long Chengyuan, Qin Zhiyuan is also quite indulgent to Long Chengyuan, so after hearing Long Chengyuan's ridicule, Qin Zhiyuan did not mean to be angry: "Don't look at it ugly, easy to use is the last word, Zhou Hongguang and Bao Deshui will fall in love with it." ”

Zhou Hongguang was the commander of the Air Force, and Bao Deshui went to the pilot school on Laute Island after carrying out a combat mission against Japan. Bao Deshui is Lanfang's first ace pilot, and is still Lanfang's biggest trump card, Bao Deshui wants to pass on his experience to those new pilots and cultivate more aces for Lanfang.

"It's hard to imagine that you look so ugly, and in terms of your aesthetic level, Your Majesty, you would actually make such a thing-" Long Chengyuan took the model of "Thunder and Lightning" and looked at it over and over, muttering non-stop.

In fact, after watching it for a long time, "Thunderbolt" is still quite cute, the chubby body is described as "cute" in the Internet language of the 21st century, and now it has become one of the Lanfang's standard weapons, "Box Cannon", "Thunderbolt" is also a typical example of ugly cuteness.

"The stout fuselage is for a stronger structure, better survivability, which can maximize the safe return of our pilots, and you should know that the pilots themselves are more valuable than the aircraft." Qin Zhiyuan wants to try his best to prove that "thunder and lightning" is ugly.

"We can ensure the survivability of the pilots in a more beautiful way, the Lanfang Air Force is arrogant and elegant, they are eagles soaring above the nine heavens, I can now foresee how much Bao Deshui will hate me when they see this plane, they will definitely think that I am jealous of them, so I use this plane to make their elegance disappear." Long Chengyuan resisted with a bitter face, but the "thunderbolt" in his hand was never willing to put it down.

"Don't care about those who have it or not, they can't love you, how can they hate you!" Qin Zhiyuan was dismissive of Long Chengyuan's resistance.

For pilots like Bao Deshui, Long Chengyuan, as the designer of the aircraft, is Bao Deshui's food and clothing parents, hate? It's really not possible, even if Long Chengyuan told Bao Deshui that they each brought a bag of black dog blood on the plane to ward off evil spirits, Bao Deshui would be convinced.

"There's a question, a stout fuselage can indeed build a stronger fuselage, but it will increase the surface volume and increase the probability of being shot, is such a design necessary?" Long Chengyuan finally began to enter the normal mode, and discussed the "thunder and lightning" itself with Qin Zhiyuan in a serious manner.

"Compared to the improved survivability, this increase in volume can be ignored, this aircraft is called 'Thunderbolt', it weighs more than all the aircraft we use now, in order to make the 'Thunderbolt' escort our bombers, it must be made to carry more fuel, and at the same time need more horsepower engines, this is all your range of work." Qin Zhiyuan immediately began to make requests, focusing his attention on the "thunder and lightning" itself.

"What about the specific parameters?" Long Chengyuan already felt the pressure, and his brows began to wrinkle.

"The flight altitude must reach 13,000 kilometers, the range must be 2,500 kilometers, the speed must be about 700 kilometers, the total weight must not exceed 7,000 kilograms, and the engine power must not be less than 2,500 horses." Qin Zhiyuan immediately became like a treasure.

The former "thunderbolt" is similar except for the difference between the range and what Qin Zhiyuan said, but if it is on the basis of reducing armaments and increasing fuel, Qin Zhiyuan's requirements can still be realized.

Of course, although Qin Zhiyuan took out the model, the internal structure was not involved at all, this is the scope of Long Chengyuan's work, Qin Zhiyuan is only determined by the aerodynamic shape, which has solved a big problem.

"Oh my God, you can kill me-" Long Chengyuan immediately wailed, threw the model in his hand on the coffee table in front of him, and then lay down on the sofa and pretended to be a dead dog.

Lan Fang's main fighter now is the "Eagle Falcon", the "Eagle Falcon" has a flight altitude of 9,000 meters, a total weight of 2,500 kilograms, a flight speed of 450 kilometers per hour, and a range of 1,200 kilometers.

"Despair" is certain, compared with the aircraft that appeared in the thirties and the planes that appeared in the forties, although they both belong to the category of propeller engines, but in terms of performance, they are worlds apart, and the span between them is unimaginable, that is, Qin Zhiyuan dared to make this request.

"Kill you, who's going to work for me? Hurry up and work, look at your belly, how old you are, you actually have a small belly! Do you still want to find a wife? Qin Zhiyuan opened the topic, not wanting to listen to Long Chengyuan's complaints.

Although Long Chengyuan is also in the military, strictly speaking, the profession he is engaged in and the military are two different things, Long Chengyuan has almost no time to exercise because of heavy scientific research tasks, and staying in the laboratory and in front of the desk for a long time, the fat in the abdomen will inevitably accumulate, which is normal.

However, as a young man who is not yet twenty-five years old, Long Chengyuan is obviously also very attentive to his image, and when he heard Qin Zhiyuan's ridicule, Long Chengyuan immediately sat up straight: "What's wrong with my small belly?" If I hadn't been in the lab all day, would I have a small belly? You don't pity me, you still laugh at me, and you don't have any sympathy—"

Probably all fat people can feel the malice from all over the world, and Long Chengyuan's reaction fully shows the grudge of a fat man.

Although Long Chengyuan doesn't look fat, he is just a little fatter than a normal person.

However, in these years, the material supply is not sufficient, and the people of Lanfang are not used to idleness, and it is not easy to find a fat man. Qin Zhiyuan is also a bone in the egg, what's wrong with being fat? Fat points prove that there is no waste of what you eat, and it is better than those who eat dry and don't grow meat!

"In fact, this requirement is not high at all, if there is no accident, this is probably our last propeller fighter, the next generation of fighters to use jet engines, when the maximum take-off weight will reach about nine to ten tons, the flight altitude will reach 20,000 meters, the flight speed will exceed Mach 2, do you think about how much advantage our air force will have at that time? It's okay to fly right over London, but what's the difficulty now? Qin Zhiyuan painted a picture of a better future to Long Chengyuan, and for technicians like Long Chengyuan, only using new technology can arouse their interest.

"Wait, jet engines? What the hell is that? Long Chengyuan really took the bait.

In fact, as early as the 17th century, there were attempts to use steam power or internal combustion engines to achieve a usable jet engine, such as the Dutch physicist Huygens and later the Romanian Henri Koanda, but due to the technical conditions of the time, these attempts failed.

In the twentieth century, the jet engine finally made progress, and just last year, the Frenchman Maxime Guillaume patented the first jet engine. But that didn't help, as a report published by the National Bureau of Standards in October questioned the role of jet engines.

The report argues that jet engines had little economic value for low-altitude flight at the time, and even specifically states that "it now appears that any possible jet propulsion has little practical value, even for military use." ”

It is normal for any new thing to be born with great difficulty at the beginning.
