"Boom~~~" A violent roar that rushed straight to the ear drum came from the sky, like a dull thunderclap exploding in the ears. Pen, fun, pavilion www. biquge。 info

Standing inside the thick fortifications, Zhang Cheng frowned tightly and held up the high-powered telescope to look at the blue sky covered with layers of thick clouds like white cotton. His eyes remained motionless and followed a black figure shuttling through the clouds at high speed.

The black figure in the sky was extremely fast, and it would leave a faint white trail as it flew through the sky. The sound it makes when flying at the same time is very strange and completely different from the piston engine of the past.

After a while, Zhang Cheng put down the telescope in his hand, turned to look at several scientific and technological personnel behind him, and asked loudly, "How is the ability of the engine?" How long is lifespan? ”

This is a flight test base. Flying in the sky is a turbojet engine that is an epoch-making technology for this era. This method of using compressed air to ignite the fuel, and then the expanded air is ejected backwards through the impeller to obtain power, which is very different from that of a piston engine.

Zhang Cheng, who is from modern time and space, used to see the wars breaking out everywhere on TV all day long, and the most eye-catching ones were the fighters of various countries. And these fighters are all such turbojets without exception. No matter how advanced its performance is, the principle is the same.

Zhang Cheng naturally will not let go of this mainstream trend in the future, and began to invest in the construction of various laboratories and equipment factories as early as possible. After theoretical and data experiments, prototypes and demonstrators are being introduced. After such a long period of research and development, coupled with Zhang Cheng on the side to provide guidance and core technical guidance, the project plan was implemented very quickly.

Zhang Cheng came here today to watch an experimental flight. No matter how perfect the theory is, no matter how detailed the data is, it cannot compare with a successful flight, nor can it compare with the personal experience of the test pilots. As the main driving force and highly valued project, it is not surprising that Zhang Cheng came to watch it in person.

"Your Excellency." The main R&D personnel who have been accompanying Zhang Cheng hurriedly responded, "Our engine is the Kunlun 3 engine provided by the first machinery factory in Beijing, with a static thrust of 850 kg at sea level, a fuel consumption of 1650 kg per hour, a dead weight of 720 kg, a thrust-to-weight ratio of 1.181, and a life of 50 hours. After a pause, the developer continued, "This is the best engine we could find." ”

"The engine is terrible!" Zhang Cheng frowned and said in a deep voice.

Zhang Cheng never thought that with the technology of this era, he would be able to make such an advanced super fighter at once. But it can't be too bad. Zhang Cheng's ideal first-generation jet fighter is the J-5, a single-engine, single-seat high subsonic fighter. It's just that the technology in aero engines in this era has not yet reached such an excellent level.

It's easy to say anything else. Whether it is the material of the fuselage or the shape design, the aerodynamic layout or the armament or anything, there is no problem. The core component that really determines the real performance of a fighter can only be the engine. Without a powerful, reliable engine, nothing else is moot.

Looking at the R&D personnel who were a little frightened, Zhang Cheng also knew that this kind of thing had nothing to do with them. Breathing a sigh of relief, he put down the telescope in his hand and said, "Give an order to the No. 1 Machinery Manufacturing Factory in Beijing, and order them to develop a new engine that can meet the requirements of technical indicators as soon as possible." What is needed goes directly to the logistics committee of the Supreme High Command and puts their needs into a first-class list. I don't care about anything else, I just want the best engine. ”

Although now the technical capabilities are already available. But Zhang Cheng knows very well in his heart that this kind of engine with rough workmanship and extremely short life is more like an untimed bomb, and he doesn't know when it will send its driver to the west. Zhang Cheng was reluctant to push this kind of thing into the battlefield when the technology was not yet mature. The Ming Dynasty now has an advantage on the battlefield.

In fact, at this time, Daming's aviation power had basically reached the peak level of piston engines. They have been constantly improving several main models and introducing even better models.

On the one hand, the design of these models is already perfect, and it is good to constantly optimize it. Another reason is that Zhang Cheng knows that these piston fighters, which now seem invincible in the world, will eventually be replaced by more advanced turbojet fighters. Then there is no need to cling to it while gaining technological and numerical superiority. After all, it is a product that is destined to become obsolete.

Zhang Cheng knows very well that the mainstream on the battlefield is still piston fighters, and if there are no accidents, this kind of fighter will be used until the end of the war. As for the jet planes that will dominate the sky, they may be able to show their strength in war, but they will definitely not be able to take shape in a short period of time.

Zhang Cheng does not expect to rely on jets to dominate the world, and the technology he wants is mature in one step. Now the most flying in the sky is the ME262 level, although the performance is very powerful, but it is still a high-altitude and high-speed type. This was used against large bomber groups. And at this moment, the need for this weapon is not high. Moreover, the reliability of this new weapon is far from reaching the stage of large-scale combat application.

In the end, Zhang Cheng was determined to continue to optimize the technology, and when the technology matured, he would directly go to the Jian-5, a generation of jet fighters in the true sense. After the Ming Dynasty fully popularizes the Jian-5, the sky of this war will completely belong to the Ming Dynasty.

"Let's go." Zhang Cheng waved his hand, "Go to the airport and listen to what the pilot has to say." ”

The test pilots who flew the new jet were no ordinary people. Because this project is very important, the army aviation specially asked their first ace Sha Jin if he would like to fly the new aircraft for a test flight. Unsurprisingly, Sha Jin agreed to the mission. Flying a new aircraft is definitely a very dangerous job. Because no one knows how the new aircraft will perform, whether there are any potential problems, all of this needs to be found out by the test pilots.

As the first crash king of Army Airlines, and the only super ace with more than 100 crashes so far, it is also a great risk for Army Airlines to call Sha Jin to be a test pilot. It can also be seen from this that the army airlines are expecting more than the new aircraft.

"Lu Hang is really willing to use you as a test pilot." Seeing Sha Jin trotting all the way over to salute, Zhang Cheng smiled and raised his hand to return a military salute, "I am the commander of the Army Airlines, why don't I know about this matter?" If something happens to you, the super ace, then the loss of Lu Hang will be great. ”

What Zhang Cheng said was just a joke, he was the commander of the Army Airlines, and the jet project was vigorously promoted by him, how could he not know about this kind of thing? It's just a good-natured joke.

"Report to the Commander." Sha Jin pursed the corners of his lips and chuckled, "I am a soldier, and it is my duty to obey orders." And I really like to fly this new plane. "Zhang Cheng is both the supreme commander and the commander of the army aviation, and he is Sha Jin's top boss.

"How do you feel about this aircraft as a good pilot?" Zhang Cheng looked at the testing machine on the runway not far away and asked out loud.

"It's very fast, it's unbelievably fast." Sha Jin first said the biggest advantage of jet aircraft: "With this kind of ultra-high speed, you are basically in an undefeated position in air combat." I can run when I'm done, and all the enemies won't try to catch up with me. This one-sided advantage can almost completely determine the victory or defeat on the battlefield. ”

After talking about the advantages, Sha Jin frowned and began to tell his feelings: "But I feel that the handling performance is still very poor." I don't know if it's the structure of the fuselage, the material process, or the overall design, there will be flutter when flying at high speeds. And I felt that the engine performance was not stable, and I couldn't maintain a stable flight condition all the time. ”

"To put it simply, it can fly, but its performance does not meet the operational requirements." After Zhang Cheng summed up, he looked at the scientific researchers around him and said, "You still have to continue to work hard, and I hope to hear your good news as soon as possible." But don't be too fast. I want a mature product, not a semi-finished product that is urgently launched. ”

"Yes."

......

"Do you think we're going to win a jackpot?" In the vast and ethereal Pacific Ocean, the Killer Whale, the latest S300 large ocean-going submarine of the Ming Navy, is floating on the surface of the sea and sailing at a low speed to recharge its batteries. On the bridge control tower, Lieutenant Colonel Fang Renxu, the super ace commander of the submarine unit of the Ming Navy, took out a windproof lighter to light a cigarette for himself, and asked the first mate on the side.

Since then, he has sunk the Yamashiro and sunk the Shozuru, and then he has obtained some other achievements. Fang Renxu became the submarine commander with the largest tonnage of sunk warships in the history of the submarine force.

Even if some of his colleagues have surpassed him in the total tonnage of ships sunk, he is still a unique trump card in terms of the tonnage of battleships sunk. This also made Fang Renxu not very interested in ordinary targets, and his main energy was focused on the battleship.

This time, the Ming Navy and the U.S. Navy are about to start an unprecedentedly powerful showdown near the Hawaiian Islands, how can there be no submarine troops to participate in the war. As the best submarine commander, Fang Renxu and his crew took over a large ocean-going submarine of the latest type, and then set off from Pearl Harbor for combat patrols off the coast of the Americas.

"That's not good." The first mate, who had a bearded face, took the lighter handed over by Fang Renxu and lit a cigarette, and said, "The situation on the battlefield is changing rapidly, who knows what will happen in the next minute?" But I'm sure with you, we won't be empty-handed this time. You're a battleship killer. ”

"Hey~~~" Fang Renxu smiled and opened his mouth, and was about to say something, when the sentry in charge of the lookout suddenly shouted loudly: "There is a situation!" (To be continued.) )
