Chapter 21 Encountering Spies on the Return Journey
Laboratory No. 78.
Lin Dong was unaware that Lin Weiliang was about to be promoted to deputy chief engineer.
He remotely controlled the Hot 001 model drone, maintaining an altitude of 8000 meters and an optimal speed of Mach 0.7 as it flew towards the Guangdong province.
"Wow, Lin Dong, look! What city is that down there? There's such a huge expanse of lights!"
About half an hour after the model airplane flew out, Xu Qingling suddenly seemed to see something and pointed in surprise at a large area of lights below in the camera's view.
"Chongqing is one of the four municipalities directly under the central government in China."
Lin Dong glanced at the map and replied, "More than ten years ago, this was part of Sichuan. It was separated from Sichuan in 1997. Uncle Xu must have taken you to Chongqing when you went on a trip, right?"
"Yes, I've been there, several times."
Xu Qingling yawned and counted on her fingers, saying, "I've been to Hongyadong, Jiefangbei, and even stayed at Shibatidi for a week. My dad also told me stories about the Chongqing Anti-Japanese War while he was at Jiefangbei."
"So you can say you saw Chongqing from the sky today, even though it was at night."
Lin Dong smiled and looked at Xu Qingling yawning: "If you're sleepy, you can take a nap over there. There's a recliner behind the door, and a box and a blanket next to it."
"Mmm, I'm so tired from the drive home today, I'm going to sleep."
"Lin Dong, call me when you get back, don't leave me behind."
Xu Qingling yawned, went into the laboratory, dragged out a recliner, lay down next to Lin Dong, closed her eyes, and soon fell asleep.
"..."
When Lin Dong saw Xu Qingling drag out a chair to sleep, he shook his head and moved his laptop to the side so that the screen light wouldn't shine into her eyes.
With Xu Qingling's various questions gone, Lin Dong set up automatic cruise control and began to examine the test flight data collected that day.
"The performance of the servo motors still has a lot of room for improvement, and the performance of the twin engines has never been fully utilized."
"With further improvements to the control algorithm, the shape and aerodynamic layout of the aircraft can be adjusted, upgrading the model aircraft from subsonic to transonic and entering the field of supersonic aircraft."
Although in the aerospace field, there has always been the saying that there are large flying bricks.
Even now, the fastest man-made object in human history is not an intercontinental ballistic missile or a space rocket, but a nuclear-powered manhole cover.
However, for a proper aircraft, engine thrust is crucial for stable supersonic flight, as are fuselage shape and aerodynamic layout.
If the fuselage shape and aerodynamic layout are not up to standard, the air resistance of the fuselage will be too great.
So, when faced with the air shock waves generated at supersonic speeds, the entire fuselage would be torn apart by the shock waves, making stable flight impossible.
In addition, when facing the powerful air pressure at supersonic speeds, the aircraft's servo performance must keep up, and the control program must be adapted to the aerodynamic layout of supersonic speeds.
Otherwise, if the aircraft enters supersonic speed, it will either be unable to turn around, or turning around will result in loss of control.
time flies.
Soon, Hot001 traveled more than a thousand kilometers and arrived in the offshore area of Guangdong Province.
Lin Dong began to descend, activating all the low-light cameras, high-speed cameras, and infrared cameras. A nighttime sea view, synthesized from multiple lenses, was projected onto the screen.
"The communication technology is still a bit lacking; the communication bandwidth is seriously insufficient, so the transmitted images are all compressed."
Lin Dong looked at the screen and suddenly typed in a line of code, causing the screen to immediately stop displaying the message.
Apart from the necessary model aircraft control commands, all other communication bandwidth is occupied by the code program.
After waiting for about ten seconds, a high-resolution image popped up on the screen, the bandwidth was released again, and the avionics display was restored.
This is a seascape photo taken at night.
The moon shines in the sky, and the waves on the sea roll. Some waves are smooth, reflecting the image of the full moon, while others are broken, shimmering with a silvery-white hue.
A group of dolphins leaped out of the water, creating countless splashes, seemingly chasing the moon.
Based on the moon's position, in the distance of the image, one can also see the silhouettes of some fishing boats, cargo ships, and even yachts.
"Beyond that is the South China Sea..." Lin Dong looked at the scene, his gaze fixed on the farthest point of the screen. He stepped on the rudder, pushed the throttle and the control stick.
boom--
The avionics interface suddenly changed the aircraft's attitude.
The model drone circled once on the sea surface, its nose pointing northwest, and began to fly back.
The model aircraft still has fuel left over, enough to fly a little further before returning.
But Lin Dong understood that the southern sea area at this time was not the South China Sea before his rebirth.
At this time, an unfamiliar aircraft from the mainland entered the South China Sea. Once discovered, it will inevitably cause many troublesome disputes.
"Therefore, it's better for aircraft to be stealthy."
"Ideally, it would be a combination of radar stealth and optical stealth, so that one could wander around freely without being detected... Hmm, if such technology existed, even if one were discovered, there would be no fear."
Lin Dong, feeling a sense of anticipation, increased the altitude of the model drone and began its high-altitude return journey.
"Once we return to Chengdu Aircraft Industry Group, we'll head to the dedicated test flight area to begin testing extreme maneuverability and the laser strike effects..."
After setting up the automatic return, Lin Dong glanced at the remaining fuel level, estimated the amount of fuel left upon returning to Chengdu Aircraft Industry Group, and took out paper and pen to begin designing the procedures for the extreme maneuver test.
"The engine has enough thrust, but it's not a vectoring nozzle."
"Maneuvers like the Falling Leaf, the Bell Maneuver, the Herbst Maneuver, and the Cobra Maneuver, which involve post-stall maneuvers, cannot be tested..."
"Hmm, it seems there's another area to upgrade for the next model airplane upgrade."
Lin Dong noted down the vector engine feature. When the model drone returned to the test flight area of Chengdu Aircraft Industry Group, he was about to descend to a lower altitude to begin testing.
Suddenly, a beep sounded.
A red dot suddenly appeared on the avionics interface displayed on the laptop screen, warning of a potential risk below.
Ok?
Infrared signal? Large mammals?
Lin Dong paused for a moment, then zoomed in on the signal.
A humanoid infrared image appeared in the lens... not an animal, but a person.
"Is there anyone else doing test flights this late besides me? But why is there only one person for a test flight mission?"
A hint of doubt and wariness appeared in Lin Dong's eyes. He quickly activated multiple cameras, including a low-light lens, and entered a code to request high-definition image transmission.
As a family member of Chengdu Aircraft Industry Group, Lin Dong has a certain understanding of the test flight rules.
Because it's a new aircraft, nobody knows what risks it might pose.
To ensure the safety of the pilots and the aircraft, test flights are usually conducted during the day when the weather is good, and it is impossible for only one person to conduct a test flight.
After waiting for about ten seconds, a high-definition image popped up. It showed a middle-aged man with an ordinary appearance whom Lin Dong did not recognize.
"Why are they acting so suspiciously... Wait, is someone else here?"
Lin Dong carefully examined the image. Suddenly, he paused, turned his head to look at the animated model airplane interface.
A new infrared signal entered the range of the model aircraft's infrared camera. Judging from the direction of movement, the two people were about to meet.
"At Chengdu Aircraft Industry Group's test range, instead of sleeping at night, two people were meeting alone..." Lin Dong's eyes widened: "This is a spy!"
