Chapter 561

However, Chen Mo did not adjust the shape of the mind force wrapped in the outside of the body to the shape of water drop.

Although the drag coefficient of water droplet is the smallest, it is limited to the case of conventional speed. Once the speed exceeds the speed of sound, the situation will be more complex.

When the aircraft is flying in the air, the front end will disturb the air. This disturbance will propagate in the form of disturbance wave at the speed of sound. When the speed of the aircraft is less than the speed of sound, the disturbance wave will propagate directly in all directions and will not affect the aircraft.

However, when the object is moving at supersonic speed, the propagation speed of the disturbance wave is smaller than the forward speed of the aircraft. In this way, the subsequent disturbance generated by the aircraft will be superposed with the previous disturbance wave, forming a strong wave, and the air will be strongly compressed to form a shock wave.

In a sonic fighter, the shock resistance will account for a large proportion in supersonic flight.

In order to reduce the shock resistance, the fighter needs to be designed to conform to the shape of "area ratio" and the design of "area ratio". In short, the cross-sectional area of the aircraft should be increased smoothly from the nose to the place close to the tail, and then reduced smoothly until the end of the tail.

The overall cross-sectional area of the aircraft should be reduced as much as possible.

That's why we see ordinary airliners that are closer to water droplets, while supersonic fighters are more flat and sharp.

Therefore, after Chen Mo tried according to this rule, he finally controlled his mind power to become a flat shuttle shape that could cover his body. The largest cross-sectional area in the middle of the shuttle shape is basically the same as that of his trunk part, and the front and rear head and foot parts are gradually reduced, forming two sharp corners as sharp as the tip of the sword. The shape of

is the principle of Chen Min's minimum flight resistance adjusted by the principle of minimizing air resistance and shock resistance.

"Jarvis, report speed."

Chen felt that after changing the shape of the mental shell, the speed of flight increased. When the speed increased to the highest level, he asked Jarvis again.

"Sir, you are now flying at Mach 3."

Hearing this, Chen Mo shook his head regretfully, which was a lot higher than before, but the highest speed was still much lower than that of the six Mach of the iron and steel battle clothes.

It seems that long-distance flight depends on iron and steel battle clothes. At least at present, his own flight speed is not as fast as that of iron and steel battle clothes, and he has to continuously consume mental power. Although the consumption range is very small, with his current mental strength, it's no problem to fly with all his strength for several hours, but after all, it's not as simple and convenient as iron and steel battle clothes.

But when he thought of steel battle clothes, Chen Mo soon had a new idea.

He first slowed down and hovered in the air. Then he thought about it, and then he released the steel armor directly from the space.

The dark Edelman alloy steel battle suit appeared in front of Chen Mo instantly, wrapped the first half of his body directly, and then a low mechanical transmission sound accompanied by the crisp metal impact sound sounded continuously. The armor unfolded on both sides of the battle suit quickly deformed and closed, wrapping Chen Mo completely.

Dress up!

The whole process takes less than a second!

From the release of the battle clothes to the deformation and closure of the armor, the speed is extremely fast. Almost in a flash, the clothing has been completed. This is the result of Chen Mo's continuous optimization and improvement, in order to shorten the clothing time as much as possible, so as not to be caught by the enemy.

After putting on the steel battle suit, Chen Mo didn't start the propeller, but still used his mind to hold the battle suit and himself in the air. This time, Chen clearly felt the weight increase. Although he didn't use the power to fly at full speed just now, it was not as easy as at the beginning.

Chen Mo's own weight is about 100 kg. With the weight of 200 kg of steel and war clothes, the overall weight has reached 300 kg.

However, Chen Mo just feels heavier. With his current strength of mind power, it's no problem to lift the weight of 300 kg. Although it hasn't been tested accurately, according to his feeling, the current maximum strength of mind power control object should be able to reach one ton left and right.

will talk about the air adjustment posture. The steel war suit itself is controlled by the thrusters of the hands and feet and chest and abdomen. Although Chen Mo can manipulate and manipulate, it can be manipulated flexibly, but it is far less convenient and faster than the mental power. Chen Mo directly uses the power to control the battle suit to adjust the flight posture, and his hands are still stretched on the sides of the body naturally.

Then, under the control of Chen Mo, the propellers of the feet, hands and chest and abdomen of the iron and steel war clothes were started at the same time, and the white flames were ejected, pushing the war clothes to fly forward rapidly.

When the holographic projection inside the helmet shows that the speed reaches the maximum speed and Mach 6, Chen Mo once again applies his mind power to the battle suit, adding another impetus to it.

The iron and steel battle suit with stable speed accelerates again and continues to improve rapidly. Soon it reaches a new speed limit, Mach 7!

Although the speed is only increased by one mach, in the case of supersonic speed, with the increase of speed, the increase of resistance will be larger and larger, and the later, the harder the speed is to be improved.In the real world, the speed of the fastest fighter is only Mach 3.2. NASA has built a hypersonic aircraft with a maximum speed of Mach 9.8, the x-43. It's just an unmanned test aircraft dedicated to the research of scramjet. It has no practical value at all. Its flight needs to be carried to a height of 100000 feet by a B-52 bomber, and then by a fire The rocket takes it into a higher orbit and accelerates to a very high speed. Finally, it is separated from the rocket. It is powered by a specially developed supersonic ramjet engine. It can continue to fly for about 10 seconds. After reaching the limit speed of Mach 9.8 for a short time, it will lose its power and fall into the sea.

Compared with them, Chen Mo's current speed of Mach 7 is astounding, and it's not over yet.

Although the shape of the iron and steel battle suit has been optimized and the wind resistance coefficient is very low, its main function is to fight, so the shape cannot be changed too much in order to pursue low wind resistance. Therefore, compared with the fighter, its flight resistance is still a little large. Although the powerful power enables it to maintain a high speed, if the shape can be further optimized , we can still make great progress.

Therefore, Chen Mo once again formed a new "armor" on the outer layer of the battle suit, changed its dynamic shape into a shuttle shape, and the flight speed of the battle suit was also increased again, finally reaching eight times the speed of sound! That is 9800 kilometers per hour, nearly 10000 kilometers per hour!
