Genius is just the threshold for me!

Laboratory No. 78.

On the 200-inch screen flight interface, the altitude parameters of the Hot 4 are rapidly increasing.

Soon, the entire Hot 4 rocket soared to an altitude of 30,000 meters, maintaining a subsonic speed of Mach 0.85.

Lin Dong scanned the parameters on the flight interface, entered a line of automatic flight code, and then activated the Hot No. 4's super aerial photography cannon.

Di-

The image on the main screen flashed briefly.

The next moment, an image of a street scene in Chengdu appeared below.

Cars, pedestrians, the quartz bricks of the sidewalk, the light and shadow cast by the sun, and even the leaves of the green trees are all captured clearly.

"That's a bit perverted."

Lin Dong looked at the image's precision and clarity, and nodded in approval.

Although there is a significant atmospheric disturbance at a distance of 30 kilometers from high altitude to the ground.

However, after algorithmic repair, the entire image is indistinguishable from a close-up shot taken from the ground.

Lin Dong adjusted the focus and continued shooting, with images being transmitted back one after another.

With each subsequent image, the area of ​​the image would increase by one size, and soon, the diameter of the image area would expand to 15 kilometers before stopping completely.

The originally high-definition image now becomes blurry.

Aside from some large buildings and streets that can be distinguished by the naked eye, other trees, cars, and pedestrians can only be identified through algorithmic analysis.

"It seems that this purely optical system is only suitable for long-term fixed-point surveillance and sightseeing. Its reconnaissance and search capabilities are not as good as the synthetic aperture radar of the WZ-8."

Upon seeing this scene, Lin Dong immediately analyzed the differences between optical reconnaissance and radar reconnaissance.

"Qingling, open my laptop, I need to find some coordinates..." At this moment, Lin Dong seemed to have thought of something and turned to call out to Xu Qingling.

"OK."

Xu Qingling nodded and brought over the laptop she had just used to flash the Hot No. 4 firmware.

Lin Dong opened his notebook and found the data record of the last map scanner. Soon, he locked onto a latitude and longitude coordinate.

"Xiao Dong, what are you doing?"

Just then, Wang Xingguo came over from next door and saw Lin Dong suddenly inputting latitude and longitude on the flight control interface. His heart skipped a beat, and he had a bad feeling.

"Please help check my homework."

Lin Dong replied, typed in a few lines of commands, and pressed the Enter key.

boom--

The sound system simulates the roar of an engine.

On the flight interface, Hot 4's speed suddenly increased, and the sound barrier was broken without any resistance.

soon.

Hot4 arrived at the set latitude and longitude coordinates, its flight path automatically entered a circling state, and then the aerial photography cannon was turned on.

Di-

An airport, hidden in the southwestern mountains and forests, was still identifiable despite its heavy camouflage. Images of various aircraft and radar equipment were displayed on the screen.

"I……"

When Wang Xingguo saw this spoofed airport image, he felt as if the sky had fallen, and he covered his head in a terrible headache.

"Laser multi-point assisted focusing offers a significant improvement in both image quality and sharpness compared to radar assisted focusing."

Upon seeing the airport, Lin Dong expressed his approval of the multi-point laser autofocus technology and saved the photo.

Since undergoing a promotion and rectification last year, the MapScanner has flown again, but it can no longer detect airports on the ground.

But now.

With the super aerial photography cannon of Hot4 deployed and multi-point laser focusing, the military airfield below was once again laid bare.

"Ancestors, I'm only good with a pen, I can't beat them with guns..." Wang Xingguo said, his voice trembling as he saw Lin Dong save the photo.

Although they cooperated with headquarters to promote officers in the military, it used to be very satisfying for headquarters to show off and scold people.

He might do this once, but if it happened again, he was genuinely afraid of getting beaten up.

"Then let's film a few typical examples..."

Lin Dong thought for a moment and quickly made a decision: "In that case, Godfather, you can keep this confidential and fax it to headquarters so they can arrange for rectification. We're just filling in the gaps in national defense construction..."

talking.

Before Wang Xingguo could answer, Lin Dong had already pinpointed several latitude and longitude coordinates.

It took more than ten minutes to take high-definition, recognizable photos of each radar station, airport, and log well hidden in the mountains.

Lin Dong put the photos into a folder, encrypted them, and sent them to Wang Xingguo's email address. Then he pulled the control lever and pushed the accelerator lever all the way down.

boom--

The simulated engine sounded.

The real-time simulation of the Hot Air's flight attitude instantly changed from a level flight attitude to a pitching-up attitude.

The aerial footage displayed on the 200-inch screen became a blurry blur due to the inability to focus at high speed.

But the next moment, the intelligent mode was automatically activated, and the drone switched from continuous aerial photography to intermittent snapshots, capturing a series of photos.

Although the captured image is somewhat blurry, thanks to the laser autofocus, the overall image still maintains basic clarity.

"Mach 3 speed, ramjet engine activated!"

In just a moment, the Hot 4 reached Mach 3, and the variable cycle engine switched to ramjet mode, causing the speed to surge again.

"Speed ​​Mach 4... Mach 4.3... Mach 4.5... Mach 4.7..."

At some point, Xu Ziming and Jiao You also came over from next door, and everyone watched intently as the flight interface on the screen synchronized in real time.

When they saw Hot No. 4 reach Mach 4.7, everyone held their breath, waiting for the super-exciting start at Mach 5. Jiao You couldn't help but start counting down.

"Mach 4.9..."

Lin Dong looked at the flight parameters on the screen, a hint of anticipation in his eyes.

next moment.

The speed of Mach 4.9 paused for a few seconds, then suddenly jumped, and the speed of Mach 5 leaped off the screen.

Di-

The newly added engine working diagram in the corner of the flight interface immediately switched to super-powerful mode.

But at the moment of switching, the speed that had reached Mach 5 suddenly dropped, returning to Mach 4.9.

This is!

Jiao You's expression changed instantly.

But before he could react, he shouted out.

There was a bang.

The real-time simulation on the flight interface showed the engine's exhaust plume suddenly surging.

The speed, which had been decreasing, suddenly jumped forward, leaping from Mach 4.9 to Mach 5.1, then to Mach 5.2, Mach 5.3...

Almost every few seconds, the flight speed displayed on the screen would jump forward.

"It's started!"

Jiao You watched the rapidly fluctuating flight speed on the screen, and then looked at the various parameters that remained stable without any signs of fluctuation or loss of control. He could no longer contain his excitement and shouted.

"Supercharged! Teacher Xiao Dong, Supercharged! This acceleration, this thrust... it's incredible!"

"We've built the world's first scramjet engine...we built it even before the American SR-72!"

As he shouted, Jiao You's voice choked with emotion, but his tone conveyed a sense of relief.

Although the supercharged engine device that Wang Xingguo brought last time was said to be the supercharged device for the SR-72 project, it was eventually determined that this old guy was trying to cover up Lin Dong's existence by using the name of SR-72 to deceive people.

But the project codename SR-72 remains a dark cloud that has lingered in their hearts for many years.

After all, they've been working on a small-duct turbofan engine with high thrust for so many years and still haven't figured it out. The Emei project has been delayed for a long time, and the J-20 has been going into battle with a heart condition.

Meanwhile, the enemy was already developing hypersonic engines and Mach 10 aircraft. This pressure was constant, as they feared falling behind and that the enemy was moving too fast.

But now, this super-powerful engine, accelerating at Mach 7, no, Mach 8, has shattered most of the gloom in their hearts.

"That's fucking awesome!"

Wang Xingguo, his eyes also reddening, clenched his fist. Seeing the screen display Mach 9.2, where acceleration began to noticeably slow, he hurriedly cheered, "Xiao Dong, test the top speed! Turn on supercharger and test Mach 10!"

"good!"

Seeing the engine he had researched and designed for over a year, costing hundreds of millions of yuan to develop, successfully start up in the air, Lin Dong's eyes showed a hint of joy. He picked up the keyboard and began to input the control code for the supercharger.

The afterburner of a supercharged engine is different from that of a regular low-bypass turbofan engine.

In a typical small bypass turbofan engine, extra fuel is injected into the exhaust section after the turbine and ignited to generate additional thrust.

The supercharged engine increases fuel injection in the combustion chamber while simultaneously supplying oxygen through the tailpipe, reigniting the fuel that hasn't been fully burned yet, thus achieving afterburning...

Soon, Lin Dong finished entering the code for the supercharged boost and pressed the Enter key.

Boom!

The simulated engine exhaust plume on the flight interface suddenly surged to nearly 100 meters, and the speed, which had slowed down after accelerating to Mach 9.2, rapidly increased again...

The surface temperature of the fuselage, the nose and the leading edge of the wings has exceeded two thousand degrees Celsius, and the temperature of other parts has also reached more than one thousand degrees Celsius and two thousand degrees Celsius.

The entire Hot No. 4 was like a giant torch, streaking across the sky at a speed of more than 3 kilometers per second, leaving a trail of intense heat.
