Chapter 272

On the east coast of Anyang, at the port, five fully loaded ironclad ships set off again. Chang Lin was high-spirited, "This time we will play a little strategy. We will drive all the way to the southernmost coast of the state of Jin, close to the coast of the state of Liu, and start to fight north from there. Open a gap for the state of Liu. I think His Majesty of the state of Liu I will definitely be touched. Haha..."

…………

After Li Xian bid farewell to the ironclad ship again, he returned to Qingyun Valley with Xu Ren and others to watch the research of jet aircraft. I wanted to see it a few days ago, but it turned out that there was a little problem with the wind tunnel test and technical design. I modified it and delayed it for a few days.

The problem was very sudden. During the wind tunnel test, when the wind speed was as high as 800 kilometers, the floating cloud array, gathering spirit array, etc. on the plane actually started to go on strike! In addition, when the speed reached 800 kilometers, the plane began to tremble slightly.

This is actually the same problem, because the tremor of the aircraft caused the formation to fail.

This sudden change made the personnel of the flight department helpless - the plane actually trembled, and the reason could not be found after a long time of inspection. Li Xian probably knew the reason, but he didn't point it out, but asked Yun Feihong and others to study it a little bit. Technology requires accumulation and independent breakthroughs.

In the end, Yun Feihong had a whim and used spells and water flows of different colors to test the fluid mechanics at high speed, and finally found the reason. The reason is very simple, or the issue of aircraft shape design. High-altitude aircraft and low-speed aircraft have different requirements on the shape.

Among them, in aircraft design, there is a very important principle, which is the law of "constant cross-sectional area". Simply put, the wing part of a high-speed aircraft, the fuselage should shrink slightly to compensate for the increase in cross-section caused by the wing. This small rule is the key technology of supersonic aircraft. (The current supersonic aircraft are all thin-waisted)

It’s just that I don’t know the reason, it may be the reason of formation, or it may be the reason of insufficient technology accumulation, or it may even be the reason of different world laws. interference with the law.

Such recalculation and design delayed aircraft testing by several days. After another overnight rush and the use of spells to help with the construction, the new prototype finally appeared.

Jet aircraft has a completely different appearance from propeller aircraft; its capable, concise and streamlined appearance is full of inexplicable beauty and power. The first jet aircraft was a single engine, with an opening at the front and an air intake like a magic mouth, which was quite hideous.

In addition, the solution to the plane's battle method is--refining!

The previous aircraft, the floating cloud array on the propeller plane, etc., are all recorded. Burning array is a means of making magical instruments, with low cost, poor stability, and weak anti-interference ability. But now it is obvious that this cannot continue. Yun Feihong did it very simply, and directly used the method of refining magic weapons to refine the main parts of the aircraft, such as the shell and skeleton, into magic weapons.

In this way, this aircraft is a mess of solidity, and there is no need to think about supersonic thermal barriers and the like in the future. The only problem is that the cost is a bit high and messy. More than 200 "magic weapons" are used in the whole aircraft, which can be called the most expensive machine in Anyang's history. In order to connect these magic weapons, the screws are all made of black iron.

Fortunately, this first aircraft is a test aircraft, mainly testing aerodynamics, aircraft design, technological progress and accumulation, so the functions are relatively simple, and the "magic weapons" are also the lowest level.

But even so, after Yun Feihong announced the success of the wind tunnel test, countless people at the scene were still rejoicing. An aircraft pieced together from more than two hundred magic weapons, this is a real "magic technology", or "Fallen technology". Anyang's technological accumulation has reached this point, and finally crossed a threshold again.

With sufficient technology accumulation, technology began to integrate with traditional practice formations. From now on, Li Xian no longer has to worry about whether to use electric power technology or array technology, because the two have begun to merge. And the first fusion product is jet aircraft.

In the face of everyone's attention, Yun Feihong, who was exhausted, announced this miraculous object loudly in a proud tone: "The plane is 11.6 meters long, with a wingspan of 12.8 meters and a height of 5.2 meters. The wings adopt a slight sweep angle. Design. The wind tunnel test flight speed is 830 kilometers per hour, which is almost twice the maximum speed of the aircraft. Next, the actual test is required, but it may be life-threatening.

According to the current experimental data, the thrust of the engine is about three tons, which is almost the attack power of a Nascent Soul stage master with all his strength. This test data is the data of Xiao Yuquan attacking with the magic weapon hammer in a complete state.

Because of the extensive use of magic weapons, the weight of the aircraft is as high as 7 tons. If you add fuel, etc., the weight will reach 9 tons. The maximum take-off weight of the aircraft is estimated to be 13 tons, excluding the assistance of formations and magic weapons, relying only on aerodynamic force. However, considering the practicality of the aircraft, it is recommended that the take-off weight be kept below 15 tons even with the assistance of the array.

With two tons of fuel and maximum thrust, it is expected to last for about an hour. We are currently exploring storage array technology.

Finally, a layer of stainless steel was melted on the surface of the plane, hiding the brilliance of the magic weapon. "

Li Xian looked at the streamlined plane, his eyes shone brightly; with this technology, Anyang truly has the ability to protect himself. Then, Li Xian turned his head and looked at Yun Feihong, who was pale, with disheveled hair and bloodshot eyes, "How about it, can you continue?"

Yun Feihong raised his hand to cover his mouth, and yawned gracefully, "The next target is a supersonic aircraft and a high-altitude exploration rocket."

What a strong woman. Li Xian said slowly, "In the future, the aircraft department will be established separately, alongside the research department."

"Aww..." all the personnel in the aircraft department cheered. This is the first department upgrade within the Brilliant Star Group! In the past, the aircraft department, locomotive department, and ship department were subordinate departments of the machinery branch. Today, the aircraft department is the first to go out independently and become a department parallel to the research department, which can be said to have reached the sky in one step.

It was time to test the aircraft, and something went wrong - almost everyone present was scrambling to fly this unprecedented aircraft. Don't be afraid of danger, it's true to have fun.

In the end, it was Li Xian who spoke and let Xiao Yuquan and Yuquan Daoist sit in the co-pilot seat, and Yun Feihong drove it himself. Yuquan real person is responsible for Yunfeihong's safety. Now Yun Feihong is a master of the Golden Core Stage, with a magic weapon, so it is said that the danger is not great; but Li Xian is deeply impressed by the safety of the plane-in another world, once an accident occurs on a passenger plane, it is often a disaster.

Yun Feihong sat in the pilot's seat, ignited the engine through the built-in flame array, and the plane moved forward slowly, taxiing to the prepared runway, everyone held their breath.

This time, not only the planes were tested, but also the Shunfeng ear technology that has just been researched-in fact, it is the thousands of miles of sound transmission in the past, but now it is fixed in the form of a formation and powered by liquid aura alone-including planes The formations on it, etc., are all powered by liquid aura.
