Chapter 32 Flying into Critical Airspace

"Xiao Dong!"

Lin Weiliang's expression changed subconsciously when he saw the scene of the plane taking off from the ground.

Without waiting to see what would happen next, he rushed through the air currents from the model drone and quickly stood in front of Lin Dong.

As an expert who once developed aircraft and even participated in the J-20 project, which successfully completed its test flight in January of last year, Lin Weiliang understands very well how demanding it is for an aircraft to perform a takeoff from a dry ground.

If there were even the slightest flaw in the design or performance, the entire aircraft might not be able to withstand such a violent impact and would crash out of control, turning the more than one ton of aviation kerosene on board into a giant fireball.

But before he could say anything, the Hot Shot soared hundreds of meters into the air. Lin Dong pressed a button, and the engine throttle valve was fully opened, activating the engine's afterburner mode.

There was a bang.

It looked like fireworks exploded overhead.

An even stronger gust of air swept over us from above, making the trees along the entire test site rustle loudly.

Upon hearing this sound, Lin Weiliang's eyes widened suddenly, and he braved the fierce wind to look up at the sky.

As the sun set, the two Hot Air planes began to blur, and white smoke appeared around their fuselages.

The next moment, the two model drones accelerated sharply to the left and right and shot into the sky, then turned into two black dots and quickly disappeared from sight, leaving only two slowly dissipating sonic boom clouds in place, revealing what had just happened.

"This... is supersonic?"

Lin Weiliang watched the clouds slowly disperse in the sky and felt the strong wind blowing down from the sky. He couldn't believe it and shouted.

Although he had seen Lin Dong's blueprints and personally participated in the assembly of the model drone, he knew that these were two supersonic aircraft.

But who would do this on their first test flight of a supersonic aircraft?

It takes off like a spring rising from the ground, then the engine accelerates to break the sound barrier...

This kid is really not afraid that if his model drone has even the slightest design or assembly flaw, it will disintegrate and explode in the sky, causing a dangerous accident...

Thinking of this, Lin Weiliang's expression suddenly hardened, and he looked at Lin Dong with a dangerous glint in his eyes, his right hand instinctively reaching for his belt.

"Dad, as long as I verify the calculations before I participate in the assembly of the aircraft, there will be no design or assembly defects."

Lin Dong noticed Lin Weiliang's actions, shrank his neck slightly, and then confidently nodded his head the next second: "This is my ability."

When a long-endurance professional aircraft takes off at its maximum takeoff weight, half or even more of its fuselage weight is aviation kerosene, which in some ways makes it a flying bomb.

As a professional who has studied for several years, Lin Dong has always been extremely vigilant about safety accidents caused by defects in aircraft.

So every design, every assembly.

He would use his soul vision to check for any defects, thus ensuring that there were absolutely no mistakes.

"Go back and memorize the procedures and regulations for safe test flights of aircraft." Lin Weiliang stared at Lin Dong for two seconds and said in a deep voice.

"Yes, sir!"

Lin Dong agreed without hesitation.

Memorization is his greatest talent; he only needs to read it once.

"If you violate the test flight regulations in public again, you will have to copy it ten times by hand," Lin Weiliang added sternly.

"what?"

"I will make sure that in the future, when testing the limits, I will go to the unmanned extreme test flight area to conduct the test flight."

Lin Dong hesitated for a moment but still agreed, without asking for special treatment.

Because he knows that in a system, safety procedures and rules are the most fundamental guarantees.

Although he knew he was special and that the aircraft he designed and assembled would have no safety flaws.

However, as a qualified R&D engineer, one may become the chief engineer of R&D projects in the future.

He understands that following procedures means following his own authority, and only when he himself follows the procedures and rules will his subordinates follow his rules.

"Dad, could you keep an eye on the specs for me? I'm going to test the top speed and maximum altitude."

Lin Dong shouted, maintaining the engine's acceleration, and adjusted the control stick down an angle, changing the drone's attitude from straight to angled upwards, flying it out of the CD city area.

"Speed ​​1.4M, altitude 6800... Speed ​​2.1M, altitude 8900, fuselage temperature 103℃... Speed ​​2.4M, altitude 14300, fuselage temperature 189℃..."

Lin Weiliang came to Lin Dong's side and stared at the screen, professionally and quickly broadcasting the parameters of the model drone.

As the drone continues to accelerate, the temperature on its surface increases, and in the real-time simulated diagram of the fuselage, the nose area begins to turn red.

"Speed ​​2.9M, Altitude 29800m, Body Temperature 343℃..."

Lin Weiliang continued broadcasting, then suddenly shouted, "We're about to enter the heat barrier!"

Lin Dong's expression hardened, and he slightly reduced the throttle, shifting his gaze from the control interface to the drone's detailed parameter interface.

At this moment, the data of all components of the drone were constantly changing.

The infrared sensors equipped on drones have even detected infrared radiation emitted by the fuselage due to high temperatures.

At this point, after breaking the sound barrier, the drone reached the second speed barrier for aircraft—the heat barrier.

Thermal barrier refers to the temperature buildup of an aircraft's fuselage exceeding 360°C after it reaches Mach 3 speed due to high-speed friction from airflow.

Due to the high temperature, the entire aircraft began to experience a series of problems, including structural deformation, instrument failure, fuel evaporation, and even spontaneous combustion.

"No problem!"

"This time, I used titanium alloy for the outer shell of the device, which is more heat-resistant than aluminum alloy. The internal cooling system is well-designed, and all sensitive parts are thermally insulated. The device is over four meters long and its thermal expansion and deformation are not affected."

Lin Dong stared at the detailed parameter interface for a while, and after confirming that all data fluctuations were within a safe range, he breathed a sigh of relief.

Although his calculations showed that the performance of the new Hot Aircraft was sufficient to handle the thermal barrier, he was still a little nervous about breaking through the thermal barrier for the first time.

"Next comes the extreme altitude..."

Lin Dong glanced at the altitude, which had exceeded 35000 meters, and without hesitation, activated the engine's variable overpressure mode.

Click!

The real-time simulated engine operation diagram shows that the angle of the intake fan blades, including the internal compressor and turbine blades, has been deflected, a clear intake channel has been opened, and a clear overpressure combustion structure has been formed between the blades.

At this moment, the engine fan blades, which had begun to generate noticeable resistance at Mach 3, were released.

The surging air no longer needs to pass through the blades; it is directly sucked into the engine and then ignited by high-speed ram air...

boom!

The drone, which had lost power due to the thin air at high altitude and the drag of the fuselage, was suddenly propelled by a violent thrust and soared into the air at an altitude of 40,000 meters.

Then came 42,000, 43,000, and finally stopped at 45,000 meters...

"With a maximum altitude of 45,000 meters, this can definitely be called a critical airspace aircraft."

Lin Dong watched as the drone lost power again and began to descend, nodding in satisfaction. He then opened an aircraft test flight application form and turned to look at Lin Weiliang.

"Dad, there's one last mobile combat test."

"Please send this application form to the Chengdu Military Region and request their cooperation in conducting a combat test."

What?

Lin Weiliang's eyes widened suddenly as he looked at the application form Lin Dong had opened: "You want the military's fighter jets to cooperate with your experiments?"
