Genius is just the threshold for me!

Laboratory No. 78.

The flight path displayed on the 200-inch screen shows that Hot Air No. 5 is circling four or five times at Mach 0.8 at Test Flight Field No. 8.

Lin Dong picked up a piece of twice-cooked pork and put it in his mouth. He then opened the parameters on the flight interface, entered a line of code to activate the high-powered laser under Hot No. 5.

Di-

The attack interface on the flight screen flashed briefly.

The next moment, a blurry radar topographic map appeared. In a certain area in the middle of the map, the accuracy was significantly clearer, clearly showing simulated images of some slightly larger rocks, trees, etc.

This is the laser radar's auxiliary focus lock, ensuring that the laser that can be emitted hits the target in its most powerful beam segment.

The laser emitted by any laser device is shaped like a horizontal hourglass, with the center point of the hourglass being the laser focal point where the power is greatest.

To maximize the destructive effect of laser weapons, focusing accuracy is an essential skill.

Previously, the Hot 2nd and Hot 3rd generations played aerial combat and dogfights within the atmosphere, shooting down blitzkrieg fighters.

Because the maximum distance will not exceed 20 kilometers, and the target speed will not exceed Mach 2.

The laser designed by Lin Dong, along with the garbage radar that comes with the Hot Hot, can help complete tracking, locking, focusing, and attack.

But now, to launch low-orbit satellites in the critical airspace, the distance suddenly increases to hundreds of kilometers, or even one or two thousand kilometers, and at a speed of more than 7000 meters per second.

The mediocre radar that came with the Hot Air was no longer sufficient for tracking, locking, and focusing attacks, so at this point, they could only rely on the laser's own measurement and focusing capabilities.

"It's alright, but it still needs some tweaking..."

Looking at the image's precision and clarity, Lin Dong opened the background debugging interface, eating with one hand and looking at the background data with the other, adjusting the laser's focus and tracking accuracy.

In less than five minutes, the algorithm was optimized twice, and the focus optimization was completed.

Lin Dong locked onto a rock and began to change the height, speed, and orientation of Hot No. 5, but after only a few changes, the locking point drifted away.

"The laser targeting system isn't synchronized enough with the flight attitude..."

Lin Dong looked at the data in the backend, put down his chopsticks, and began typing rapidly on the keyboard.

soon.

Enter the last line of synchronization code to remotely update the system.

Lin Dong locked onto a rock again as his target, and changed his altitude, speed, and orientation once more.

But this time, no matter how it changed, the target point of the attack interface remained firmly fixed on the stone.

"Perfect!"

Lin Dong cheered, picked up his chopsticks, and shoveled the last piece of rice and twice-cooked pork into his mouth. After finishing his meal, he turned to Wang Xingguo and asked, "Godfather, did you ask how the leader is doing?"

Wang Xingguo watched as Lin Dong completed a laser attack debugging task in less than ten minutes, a task that a team might not be able to finish in two months. Even though it wasn't the first time he had heard of it, he still felt a chill run down his spine.

"...You're treated like royalty now, you can hit me if you want."

"However, the leader said to be careful, and only fire one or two missiles while it's still in operation, and do it discreetly as much as possible without being discovered..."

talking.

Wang Xingguo seemed to have thought of something and pointed to the flight interface on the screen, saying, "You should test the speed of the Hot Spicy No. 5, as well as the performance of other engines, range, etc."

Otherwise, if we shoot down the satellite, the other side will immediately pay close attention to the situation, and any subsequent test flights will expose significant risks.

"no problem."

Lin Dong put the empty lunchbox aside, moved the chair to the control panel, pulled the lever, and pushed the throttle lever all the way down.

boom--

The simulated engine sounded.

The flight path of the Hot Star changed from circling to a tangent line rushing into the distance in an instant, and its original level flight posture became a pitching-up posture.

"3 meters altitude, Mach 3.8 speed!"

In just a short while, Hot 5 reached an altitude of 30,000 meters and its speed approached Mach 4.

"The compressor and turbine are disengaging; switching to ramjet detonation mode..."

Jiao You stared at the flight interface, losing his appetite and becoming increasingly nervous.

Although the engine mode of disengaging the compressor and turbine was tested on the ground yesterday.

However, that only supports zero-speed start for the rotary detonation engine, a pure rotary detonation mode on the ground, not a hypersonic ramjet detonation mode.

Ram detonation at hypersonic speeds.

This is a mode that cannot be tested or experimented with on the ground. Now that it's in the air, no one can be sure whether it can be switched smoothly.

"Mach 3.9..."

Lin Dong looked at the flight parameters on the screen, a confident expression on his face, and picked up his cup to take a sip of water.

Di-

next moment.

The speed of Mach 3.9 paused for a moment, then suddenly jumped off the screen at Mach 4.

The schematic diagram of the cycle engine operation on the flight interface immediately switched to ramjet detonation mode.

Boom!!!

A series of intense explosions were emitted from the sound simulation.

The real-time simulation on the flight interface showed the engine's exhaust plume suddenly swell, extending tens of meters outwards.

The speed jumped directly from Mach 4 to Mach 4.2, then quickly to Mach 4.3, Mach 4.4... The entire switching process was incredibly smooth, without a single ripple.

"It went even more smoothly than the supercharged engine!" Jiao You exclaimed, his eyes wide with surprise.

Last year's supercharged engine experienced a slight lag during the switching process, with the speed decreasing and then increasing again.

But now, this knock engine rushed straight through with almost no hesitation.

"Uncle Jiao, the knock engine itself has a self-boosting characteristic."

Lin Dong put down his water glass without any surprise, looked at the flight interface and said with a light laugh, "As long as the front air intake and detonation models and the fuel injection model are matched, it will be more stable than the supercharger engine."

"Teacher Xiaodong."

Upon hearing this, Jiao You shook his head with a wry smile: "These are the core problems you mentioned, aside from the combustion chamber thermal protection solution and the rotary detonation engine..."

"It's alright. Control models are mainly based on experimental data."

Lin Dong nodded calmly and said, "Once the experimental data is available, the control model is ready. It doesn't involve any entirely new technical challenges."

"..."

Jiao You was speechless.

The experimental data is available, so the control model is ready. How come he didn't know about this?

most of the time.

Faced with a vast amount of experimental data, they had no idea where to start or what the key data was.

"Xiao Dong, you've reached Mach 8! You'll be breaking Mach 10 soon..."

At this moment, Wang Xingguo, who had been staring at the flight interface, saw the speed reach Mach 8 and couldn't help but ask with concern, "Can the communication solution and attitude stabilization control keep up with the blackout?"

At speeds above Mach 10, aircraft will inevitably encounter communication blackouts and the core challenge of attitude control.

The former is a physical phenomenon, while the latter is an extreme control scheme.

Under normal circumstances, when an aircraft reaches Mach 3, it will generate extremely high temperatures around the control surfaces due to intense aerodynamic heating, which will change the thermodynamic properties of the gas and cause the control efficiency of the control surfaces to drop sharply.

At speeds above Mach 5, the efficiency of conventional control surfaces for aircraft becomes almost zero. At this point, aircraft must rely on waverider systems combined with engine vector torque for control.

In addition to reducing the efficiency of the control surfaces, high temperatures also cause the center of pressure of the aircraft to shift forward, generating an unbalanced pitching moment at the front of the aircraft, further increasing the difficulty of control.

At this point, due to the failure of the control surfaces, the entire aircraft can only be controlled by the engine's vector thrust.

The level of difficulty, complexity, response time control, and proactive prediction required here is outrageously high.

Even the slightest deviation could cause the aircraft to stray thousands of meters, or even lead to extreme risks such as stalling, crashing, or disintegrating out of control.

Lin Dong had previously mastered the control of a Mach 10 aircraft, but now he was about to reach Mach 16, and he was genuinely a little nervous.

"The communication scheme has been verified to meet Mach 16, and the control scheme is in the same condition..."

Lin Dong, controlling the Hot Spicy, flew towards the uninhabited northwest region, saying with a smile, "As for whether it can pass the actual test, we'll find out soon enough."

Hypersonic control solutions are a global challenge, not only in the design of hypersonic aircraft but also in the precise terminal control of ballistic missiles.

In response to this challenge, in addition to vector thrust, some ballistic missiles have also developed RCS (Reaction Control System).

By arranging micro-engines in multiple directions on the missile body, precise control of the missile's terminal reentry can be achieved through such multi-directional attitude adjustment.

There are even more advanced variable center of mass control systems, such as Russia's Topol-M missile, which has a nearly 100-kilogram movable mass block designed directly inside the missile body.

By moving the position of the mass block, the missile's center of mass is changed, altering the aerodynamic torque to achieve precise hits during the terminal phase of maneuvering...

"Xiao Dong, I'm a little worried about you suddenly flying towards the uninhabited northwest region. You've never flown like this before. Twelve billion..."

Wang Xingguo noticed the Hot Spicy's change in direction immediately. Sweat suddenly beaded on his forehead as he clenched his fists, staring intently at the parameters on the flight interface: "It's already Mach 12... Mach 13... Mach 14..."

Lin Dong also stopped smiling at this moment. He looked at the Hot No. 5, which was accelerating and slowly coming to a stop, picked up the keyboard and began to input the control code for the knock engine afterburner mode.

The afterburner mode of the rotating detonation engine is different from that of turbofan and scramjet engines. Simply put, it doubles the detonation.

By increasing the detonation frequency, the combustion rate can be further increased, thereby increasing the thrust of the detonation engine...

The cost, however, is that the lifespan of the combustion chamber and the overhaul life of the engine will be consumed at a rate of tens or even hundreds of times.

soon.

After Lin Dong finished typing a series of explosion and afterburner codes, he glanced at the Hot No. 5 on the 200-inch screen, which had completely reached the Northwest No Man's Land, and pressed the Enter key.

Rumble!!!

In an instant, a deafening explosion rang out in the speakers.

The blue engine exhaust flames simulated on the flight interface instantly surged to over 150 meters, and the speed, which had slowed down after reaching Mach 14, began to increase again.

The temperature on the fuselage surface, nose and wing leading edge has exceeded 3,000 degrees Celsius, gradually approaching the temperature resistance limit of the high-entropy tantalum hafnium carbide protective layer.

At this moment, the entire Hot No. 5 was like an extremely dense red torch, or as if it were draped in the Nine-Tails' chakra cloak from the Naruto anime, streaking across the northwestern sky at a speed of more than 5 kilometers per second...
