The ups and downs of life in the Siheyuan

In the following days, Li Yuan's schedule was full, and he kept moving between the three projects of photolithography machine, upper limb prosthesis, computer, and flight control system.

From time to time, I have to go to Kyoto Institute of Technology to participate in the technical review of communication equipment.

In order to improve the working stability and reliability of flight control modules and communication equipment.

After completing the ground static test in the laboratory, a set of modules (flight control module and communication module) were loaded into the car, and two sets of modules were placed at the highest point of the school.

Two sets of modules, one set of simulated relay units and one set of simulated ground control units.

The car then circled the school playground.

When encountering a problem, everyone works together to study, analyze and solve the problem.

After half a month of getting along, the two parties became more and more understanding and agreed that in the fourth quarter, Li Yuan would fulfill his duties as an honorary professor.

Time passed quietly, and soon the day for joint coordination came.

On this day, Li Yuan appeared at a base southwest of Kyoto.

The first is the static power-on test of the flight control system.

When designing the plan, the modules are divided, and all interfaces are defined in the overall design stage for approval by several parties.

Therefore, communication is successful when connected and powered on for the first time.

According to the test procedures, after all use cases have been tested, it will be installed on the front of the Red Arrow 1 drone fuselage.

At this time, three small stealth drones similar to "B3 bombers" were parked quietly in the hangar.

A group of people are busy installing various modules and connecting lines.

The busiest among them is Li Yuan. He originally had a complete installation manual and there was no need for him to intervene.

But Li Yuan was worried and applied for a prototype to complete the installation.

His request was exactly what Mr. Chu wanted, so they hit it off immediately.

Within one day, the flight control systems and reconnaissance modules of three UAVs were installed.

Li Yuan used his telekinesis to scan the entire bodies of the three drones to ensure there were no flaws.

Next, there is the static ground and runway rolling test of the drone.

A week later, one of the drones quickly taxied on the runway, easily detached from the ground after 100 meters, and then flew at low altitude around the base.

Li Yuan and a group of engineers looked at the various data fed back on the monitor and constantly adjusted the handles and buttons on the control panel.

The drone immediately made various movements.

Then the three aircraft took off together to implement functional tests such as air networking, air relay, and ground communication.

This low-altitude test lasted for a month, during which various parameters were continuously adjusted to ensure flight safety.

Next, continue to carry out speed test, control distance test, communication distance test, and reconnaissance test.

Another half month passed like this.

Today is the stage test report meeting. I saw an officer giving instructions continuously, and three "pilots" controlling three drones.

"Tower, Unit 1 passed the self-inspection and applied for takeoff."

"Tower, Unit 2 passed the self-inspection and applied for takeoff."

"Tower, Unit 3 passed the self-inspection and applied for takeoff."

"I am the tower, authorizing takeoff. The takeoff sequence is No. 1, No. 2, and No. 3."

"Plane No. 1 has been received, and the take-off order is Plane 1, Plane 2, and Plane 3."

"Plane No. 2 has been received, and the take-off order is Plane 1, Plane 2, and Plane 3."

"Plane No. 3 has been received, and the take-off order is Plane 1, Plane 2, and Plane 3."

. . .

At this time, the No. 1 aircraft quickly began to glide, and then jumped into the air lightly within 100 meters, screaming into the sky.

Soon, Unit 2 and Unit 3 took off in sequence.

A group of experts and officers standing behind the console kept looking at the console and looking up in the air.

At this time, the military officer serving as the commentator introduced to everyone:

"There are two modes for drones to take off, one is automatic mode and the other is manual mode. The first one just now was in manual mode, and the next two were in automatic mode."

"Everyone, please look at controller No. 1. He is using the handles, buttons and monitors (drone panel) on the console to control the flight of Red Arrow 1."

"As for Unit 2 and Unit 3, just now, their controllers just entered the predetermined parameters and pressed the take-off button. The drones completed the rest of the take-off and aerial flight control."

"Please look at the monitor. They have automatically stopped climbing. The current altitude is 5.6 kilometers and the speed is Mach 1.5. They are circling and climbing rapidly above our heads."

The lower half of the three monitors are displaying various information about their respective drones.

For example, altitude, speed, fuselage pitch angle, radar information, drone status, etc.

A red dot is flashing on the upper half of the monitor, and two green dots are flashing next to it.

"The red dot in the middle represents the aircraft, and the other two green dots are the other two drones."

At this point in the introduction, the crowd began to whisper.

"Is it so smart? With just one command, it can take off and fly automatically?"

"Yes, No. 1 is constantly controlling the controller, and the flight path of the aircraft is also reflected on the monitor. The other two did not move the controller."

"Yes! This is amazing!"

. . . . . .

"Tower, aircraft No. 1 has entered the scheduled airspace, please give instructions."

"Tower, aircraft No. 2 has entered the scheduled airspace, please give instructions."

"Tower, aircraft No. 3 has entered the scheduled airspace, please give instructions."

"Unit No. 2 and Unit 3 enter fully autonomous mode. Unit No. 1 controls Unit 2 to move forward 5 kilometers at cruising speed, and controls Unit 3 to move forward 10 kilometers at cruising speed."

"Unit No. 1 received!"

"Unit No. 2 received!"

"Unit No. 3 received!"

The commentary continues:

"At this time, Plane No. 1 is circling above us, and Plane No. 2 and Plane 3 are entering the predetermined airspace according to the order of Plane 1 and are circling."

"Unit No. 1, Unit 2, Unit 3, switch to video mode."

The operator pressed the button as ordered, and the upper half of the monitor switched to a video window, which displayed ground images.

Suddenly, the monitor of unit 3 flashed several times, the image disappeared, and several large red words appeared on the monitor: signal lost, link being established. . .

"What's wrong?" Everyone asked questions one after another.

Before the commentator could explain the situation, Unit 2 also had the same problem.

Suddenly the discussion became louder.

The commentator quickly explained:

"Commanders, Unit 2 and Unit 3 are out of the ground control range, and are now controlled by Unit 1."

"Controller No. 1, please switch to the monitoring interface of Unit No. 2."

Controller No. 1 presses the switch button, and the video screen and various signals of Unit No. 2 appear on Monitor No. 1.

Then, as required, I switched to machine No. 3, and the picture was also clear.

“2、3号机与1号机保持距离，3架无人机同步向前移动10公里”，塔台继续命令。

"Commanders, please note that after the drone exceeds ground control, the following test will automatically return to base based on the inertial navigation system."

Soon, the screen on monitor No. 1 suddenly disappeared, showing the reconnection message.

After dozens of seconds, monitor No. 1 flashed several times and the screen reappeared.

The operator kept switching interfaces, and the three drones showed that they were flying normally.

"Unit No. 1, control Units No. 2 and Unit 3 to return home together."

In less than half a minute, the roar reached everyone's ears, and three drones appeared in everyone's eyes in a triangular formation.

"Ground radar, please report sky status."
