Starting with twin fighter school beauties, I am invincible

First of all, it is Ye Lingyue's J-20 stealth fighter, from the appearance, it is still painted in silver-white paint, and the overall size has not changed, but the weight is much lighter.

The same is true of Ye Lingxing's H-20 strategic bomber, due to the use of Luna titanium alloy for integrated modification and strengthening, not only the fuselage structural materials have become tougher, the protection force has been greatly enhanced, and the weight of the fuselage has also been greatly reduced and become lighter.

Of course, in addition to their appearance, the engines of Ye Lingyue and Ye Lingxing have been upgraded to the continuous rotary detonation engine made for Li Zichen, which he named the Xingyue-1 engine, which mainly uses gaseous fuel and liquid hydrocarbon fuel! The Xingyue-1 engine uses

a special annular combustion chamber that can be started at zero speed.

When the propellant is injected from the closed end of the annular combustion chamber, one or more detonation waves will be generated, which will carry out continuous rotational propagation at the top of the annular combustion chamber, and finally be discharged from the other end at high speed, and form a repeated detonation process, so as to generate a huge driving force.

detonation

engine, and Li Zichen did not disassemble Ye Lingyue and Ye Lingxing's original turbofan-15 engines, but instead added the Xingyue-1 engine to the outer duct of the original engine, combining the two together, and greatly improving the thrust-to-weight ratio.

According to computer calculations, with the new combined turbofan detonation engine, Ye Lingyue and Ye Lingxing's maximum speed has exceeded Mach 5 per hour.

You know, their previous top speed was only about Mach 2~3, which was fully doubled.

This is far from its upper limit, as their level increases, the performance and attributes of the airframe improve, and the engine efficiency will be further enhanced, and it is not impossible to even reach Mach 10!

The most important thing is that Li Zichen also changed the take-off and landing mode of Ye Lingyue and Ye Lingxing, relying on two turbofan-15 engines and Xingyue-1 engines in series front and rear to achieve vertical take-off and landing!

Among them, the turbofan-15 air intake as the front engine is arranged on the back of the fuselage, and the jet ports are arranged on both sides of the fuselage in two;

the Xingyue-1 air intake as the rear engine adopts the method of abdominal air intake, and the design of the tail nozzle also has the function of horizontal and vertical downward vector deflection to achieve backward or downward thrust output.

In this way, Ye Lingyue and Ye Lingxing, who have vertical take-off and landing capabilities, can completely act as Yu Shengwan's carrier-based aircraft

! "Zichen, you are really amazing! This kind of continuous rotary detonation engine is definitely an invention ahead of an era!" Although

he does not know much about the field of aero engines, Yu Shengwan can still understand how great the birth of the Xingyue-1 engine is!

If the relevant technology is announced, I am afraid it can cause a lot of shock in the entire Tianlong Empire and even the Blue Star Alliance, after all, which airplane girl doesn't want to have faster speed and better performance?

Li Zichen nodded, in the past few days, he has also considered developing the side business of mechanics, he can engage in more patented technologies

, and then cooperate with those consortium companies, gate valve families, and even military officials, so he will not have to worry about income in the future.

"Shengwan, when I collect more advanced materials in the future, I will also modify and strengthen your body.

Li Zichen said.

"Can I

also use my airframe?" Yu Shengwan originally thought that Li Zichen was a senior mechanic specializing in the field of fighter aircraft, but listening to him say this, it seems that his own airframe can also be modified and strengthened?

Li Zichen smiled mysteriously and didn't reveal anything more.

On the other hand, Ye Lingyue and Ye Lingxing, who had completed the modification and strengthening, also returned to the form of the machine girl, and at this time they were also full of surprise, feeling the changes in their bodies carefully, and they only felt several times stronger than before!

Now they are also very different from other J-20 or H-20 machine girls of the same model, maybe the body model can be rated as higher quality, at least S+ level!"

Let's go, I also made an appointment with our school's flight drill ground, so you can get a good feel for the changes now.

Li Zichen said hello, and left the machine repair factory with Ye Lingyue, Ye Lingxing and Yu Shengwan, who were eager to try, and rushed to a flight training ground specially used for airframe test drive and debugging.

After the appointment time arrived, Li Zichen and the four of them came to a fighter runway, and took the lead in changing from Ye Lingyue to the J-20 fuselage, and Li Zichen quickly sat in her cockpit.

With Li Zichen's current silver-level physical strength, he can easily adapt to the requirements of flying the J-20 without the protection of safety anti-load clothing or flight helmets.

!!When

Li Zichen was ready and pressed the start switch of the aero engine, the body of the J-20 suddenly sounded a high-pitched and loud dragon

roar! Pushing the throttle lever, the powerful thrust from the combined Xingyue-1 engine made the J-20 burst out at an astonishing speed in an instant, and it took off directly in place with a roar vertically without running assistance, quickly climbing in height, and soaring into the sky!

"Accelerate!".

After climbing to a certain height, Li Zichen began to test the maximum speed of the J-20 fuselage, quickly pulled the push-pull rod to the end, opened the afterburner, and controlled the throttle to reach the maximum

! "Boom, boom, boom——!!"

Immediately after, accompanied by the deafening roar of the dragon, the flight speed of the J-20 began to soar sharply

! Mach 1!Mach 2!Mach

3!

Mach

4!

Mach 5

! However, in just a dozen seconds, the J-20 accelerated to the peak level, breaking through the violent sound barrier, and reaching the ultra-hypersonic realm of five times the speed of sound! Of course, this ultra-hypersonic realm

will produce great load and pressure on the J-20 fuselage and fuel consumption, so it can not be maintained for a long time.

However, at this time, the J-20 can easily reach Mach 2 at a speed of Mach 2 without cruising with afterburner, and there is no problem in continuing to fly for half an hour or even an hour.

Li Zichen fully controlled the J-20 in the vast sky, and then continued to test drive Ye Lingxing's H-20 fuselage.

In the end, it was not until the end of the appointment time that he reluctantly walked down from the cockpit, I have to say, this is the real

speed and passion! In the future, with more advanced and cutting-edge technology, it may not be impossible for Ye Lingyue and Ye Lingxing to have Mach 10, Mach 100, the speed of light or even the speed of light!
