On the east coast of Anyang, in the port, five fully loaded armored ships set off again. Chang Lin was very angry, "This time we play a little strategy, we have been driving to the southernmost coast of Jin Guo, near the coast of Liu Guo, and from there we started to fight north. Opening a gap for Liu Guo, I think His Majesty Liu Guo Will definitely be moved. Haha..."

…………

After Li Xian bid farewell to the armored ship again, he returned to Qingyun Valley with Xu Ren and others to watch the study of the jet aircraft. I wanted to see a few days ago. As a result, the wind tunnel test and technical design were a little problem, and I revised it, which also delayed a few days.

The problem was very sudden. During the wind tunnel test, when the wind speed was up to 800 kilometers, the floating cloud array method and the gathering spirit array on the plane began to strike! In addition, when the speed reached 800 kilometers, the aircraft began to tremble slightly.

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

This sudden change left the personnel of the flight department helpless-the plane shuddered, and it was impossible to find the cause after a long inspection. Li Xian probably knew the reason, but did not point it out, but let Yun Feihong and others study it a little bit. Technology requires accumulation and independent breakthrough.

Finally, Yun Feihong had a whimsy, using spells and different colors of water to test the fluid mechanics at high speed, and finally found the reason. The reason is very simple, it is still the problem of aircraft design. High-altitude aircraft and low-speed aircraft have different appearance requirements.

One of the most important principles in aircraft design is the "constant cross-sectional area" rule. To put it simply, the wing part of a high-speed aircraft needs to be slightly retracted to compensate for the increase in cross-section caused by the wing. This little rule is the key technology of supersonic aircraft. (Now supersonic aircraft are all thin-waisted)

It’s just that I don’t know what the reason is. It may be the reason for the formation method, or it may be the reason for the insufficient technology accumulation, or even the reason for different world laws. In short, the jet aircraft designed by Yun Feihong began to receive this at 800 kilometers. Law interference.

Such recalculation and design delayed the aircraft test for several days. After rushing to work overnight and using spells to help build, new prototypes finally appeared.

The jet aircraft has a completely different appearance from the propeller aircraft; the smart, simple and streamlined appearance is full of inexplicable beauty and power. The first jet aircraft was a single engine. The opening at the front and the air intake were like a magic mouth, which was quite awkward.

In addition, the way to solve the plane against the law is-refining!

Previous flying machines, flying cloud arrays on propeller planes, etc., were all recorded. Burning array method is a method of making magic instruments, with low cost, poor stability and weak anti-interference ability. However, it is obviously not possible to continue this way. Yun Feihong also did a very simple job, directly refining the main parts of the aircraft's shell and skeleton into a magic weapon by means of refining the magic weapon.

In this way, the plane's sturdy mess, and what kind of supersonic thermal barrier in the future, need not be considered at all. The only problem is that the cost is a bit high and messy. More than 200 "magic weapons" were used up and down the entire plane, making it the most expensive machine in Anyang's history. In order to connect these magic weapons, the screws are made of black iron.

Fortunately, this first aircraft is a test aircraft. The main test is aerodynamics and aircraft design, technological progress and accumulation, so the function is relatively single, and the "magic weapon" is also the lowest level.

But even so, after Yun Feihong announced the success of the wind tunnel test, countless people still rejoiced at the scene. An airplane made up of more than two hundred magic weapons, this is really "magic technology", or "fax technology". Anyang's technology accumulation has reached this point and finally crossed a threshold again.

With enough technical accumulation, technology began to merge with the traditional practice array. In the future, Li Xian will no longer have to struggle with power technology or array technology, because the two have begun to merge. The first product of fusion is the jet aircraft.

Faced with the attention of everyone, a tired Yun Feihong announced this miraculous object loudly in an arrogant tone: "The aircraft is 11.6 meters long, the wingspan is 12.8 meters, and the height is 5.2 meters. The wings use a slight sweep angle Design. The speed of the wind tunnel test is 830 kilometers per hour, which is almost twice the maximum speed of the aircraft. The actual test is required next, but it may be life-threatening. It requires the Jindan stage, preferably the Yuan infant stage master test.

According to the current experimental data, the engine thrust is about three tons, which is almost the attack power of the Yuan infantry master. This test data is the data that Xiao Yuquan used the magic weapon to attack in full condition.

Because of the massive use of magic weapons, the aircraft weighs up to 7 tons. If fuel oil is added, the weight will reach 9 tons. Not counting the formation method and magic weapon assistance, relying only on aerodynamics, the maximum takeoff weight of the aircraft is expected to be 13 tons. However, considering the practicality of the aircraft, even with the aid of the array method, it is recommended that the take-off weight be controlled below 15 tons.

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

Finally, a layer of stainless steel was melted on the surface of the aircraft, masking the glory of the magic weapon. "

Li Xian looked at the streamlined aircraft, and his eyes were shining brilliantly; with this technology, Anyang is truly capable of self-protection. Later, Li Xian turned to look at the side of the pale face, some hair scattered, and his eyes full of blood, Yun Feihong, "How can I still persevere?"

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

Really a strong woman. Li Xian said slowly, "In the future, the aircraft department will be established separately and be in parallel with the research department.

"Oh..." cheered everyone in the aircraft department. This is the first departmental upgrade within Bright Star Group! In the past, the aircraft department, locomotive department, and shipping department were subordinate departments of the machinery branch. Today, the aircraft department is the first to go out independently, and to become a department alongside the research department, which can be described as a step forward.

The plane is about to be tested next, and then something went wrong-almost everyone present was scrambling to fly this unprecedented plane. Don't be afraid of danger.

Finally, Li Xian opened his mouth and let Xiao Yuquan and Yuquan live in the co-pilot position. Yun Feihong personally drove. Yu Quan is actually responsible for Yun Feihong's safety. Now Yun Feihong is a master of Jindan period. He is a magic weapon, which is supposed to be less dangerous; but Li Xian is very impressed with the safety of the aircraft-in another world, once the passenger plane has an accident, it is often a disaster.

Yun Feihong sat in the driving position and ignited the engine through the built-in flame array. The aircraft moved forward slowly, sliding to the prepared runway, and everyone held their breath.

This time, not only the aircraft, but also the tailwind ear technology just researched-in fact, it is a thousand miles of sound in the past, but now it is fixed in the form of an array, and is powered by liquid aura-including the aircraft The formation methods above are all powered by liquid aura.
