Chapter 565: Simulated Takeoff

After the meal, everyone didn't linger, took a short twenty‑minute break, then immediately returned to their posts to prepare for the afternoon's full-system linkage test.

Lin Qinhua rechecked the connection of the coating detector, verifying the parameters adjusted in the morning;

Chen Mo and his team performed the final debugging of the avionics system, optimizing the command transmission algorithm;

Xiao Zhang, together with the technicians, checked the navigation system's satellite signal docking and simulated positioning under complex weather; Lin Zhengcheng organized the procedure for the full-system linkage test, devised contingency plans for sudden issues, and ensured the test would proceed smoothly.

At 2 p. m., the full-system linkage test officially started. Lin Zhengcheng pressed the start button; instantly, the workshop's machinery roared again, the engine began to turn slowly, and all systems—avionics, navigation, cooling, and stealth coating—activated simultaneously. The instrument screens filled with rapidly jumping parameters, as if narrating the hardship and hope of this tough endeavor.

"Simulated takeoff conditions, engage!" Lin Zhengcheng commanded loudly. Chen Mo immediately sent the takeoff control command; engine speed rose quickly, the cooling system kicked in, Lin Qinhua watched the coating reflectance data closely, while Xiao Zhang monitored the navigation system's positioning accuracy.

"Engine speed normal, cooling temperature normal, coating reflectance 0.01 square meter, navigation positioning precise, no abnormalities!" Each reported in turn, their tones full of seriousness.

"Simulated cruise conditions, engage!"

Lin Zhengcheng gave the command again; Chen Mo adjusted the avionics parameters to simulate cruise speed and altitude, the navigation system updated position info in real time, the coating system continuously monitored reflectance, and the cooling system adjusted its intensity according to engine speed. "Cruise speed normal, altitude normal, coating reflectance stable, navigation positioning without deviation, all systems working together smoothly, no abnormalities!"

Next, the simulated flight conditions under complex weather were activated: the heavy rain, strong wind, and heavy fog simulation systems were turned on to test how each system performed in adverse weather.

The heavy rain simulation started; water poured down the workshop's simulated pipes, scouring the fuselage skin. Lin Qinhua watched the coating detector closely, ensuring the coating's reflectance did not fluctuate under the rain's scouring.

The strong wind simulation started; the workshop's simulated fans whistled, the fuselage swayed slightly, and Chen Mo monitored the avionics' command transmission to ensure it was unaffected by the wind.

The heavy fog simulation started; visibility dropped sharply, and Xiao Zhang monitored the navigation system's positioning accuracy, making sure the positioning error stayed under 0.5 meters in the fog.

"Heavy rain condition: coating reflectance normal, avionics command transmission normal, navigation positioning precise, no abnormalities!"

"Strong wind condition: fuselage stable, avionics system normal, cooling system normal, no abnormalities!"

"Heavy fog condition: navigation positioning error 0.4 meter, meets standard, all systems working together smoothly, no abnormalities!" As everyone reported, Lin Zhengcheng's worried heart gradually eased.

Just then, Xiao Zhang suddenly shouted:

"Something's wrong—the navigation system's satellite signal has a slight interruption, positioning accuracy has deviated to 1.2 meters!" Everyone's eyes instantly focused on the navigation screen; sure enough, the positioning signal flickered, the error value kept rising, exceeding the standard range.

Lin Zhengcheng's face instantly turned grave: "What's happening? The heavy fog simulation was fine just a moment ago—why did the signal suddenly cut out?"

Xiao Zhang quickly inspected the navigation module, his brows furrowed tightly:

"I don't know—the satellite signal suddenly became unstable, as if interfered with; I tried to re‑dock the signal, but couldn't."

Chen Mo also immediately said: "Let me check the avionics system—could its signal transmission be affecting the navigation system?"

Saying that, he quickly operated the avionics console, checked the signal transmission channels, but found no abnormalities.

Lin Shengli also walked over, stared at the navigation screen, pondered for a moment, and said:

"Could it be that under the simulated heavy fog, signal transmission suffered interference? Or perhaps the navigation module's interface has poor contact? Xiao Zhang, immediately check the navigation module's interface to see if it's loose; Chen Mo, assist Xiao Zhang in inspecting the signal transmission lines; Qinhua, keep monitoring the other systems to ensure they work normally and aren't affected."

"Understood!" Everyone sprang into action; Xiao Zhang and Chen Mo hurried to the navigation module on the fuselage's underside, carefully opened the interface, and examined the wiring connections.

Xiao Zhang gently tightened the interface's mounting bolts with a screwdriver, examined the wiring closely, and suddenly noticed that one wire's connector was slightly loose—likely caused by the fuselage shaking during the strong wind simulation earlier.

"Found it! The wire connector is loose, causing unstable signal transmission and the interruption." Xiao Zhang shouted excitedly, immediately used a tool to tighten the connector and reconnected the wire properly.

Chen Mo immediately restarted the navigation system, re‑docked the satellite signal; shortly after, the positioning signal on the screen stabilized, the error value gradually decreased, and finally returned to 0.4 meter, meeting the standard.

"Navigation system back to normal, satellite signal stable, positioning accuracy meets requirements!" Xiao Zhang reported loudly, his face full of accomplishment.

Lin Zhengcheng let out a breath, patted Xiao Zhang's shoulder, and said with a smile:

"Well done, you observed carefully and handled it promptly; otherwise, if this problem persisted, it would affect the entire joint‑debugging schedule."

After resolving the navigation glitch, the full‑system linkage test continued. Next came the simulated landing conditions: Chen Mo sent the landing control command, engine speed gradually decreased, the navigation system precisely located the touchdown point, the cooling system slowly shut down, the coating system kept monitoring reflectance, and all systems worked together in orderly fashion. "Landing condition simulation completed, all systems operating normally, no abnormalities whatsoever!"

Afterward, the team ran multiple full‑system linkage tests, simulating various flight conditions, repeatedly checking all parameters to ensure every system could work together smoothly and that all parameters met the flight‑test requirements.

The sun set westward; golden afterglow streamed through the workshop's glass windows, bathing the fuselage in a warm golden edge, and also fell on each person, making the sweat on their faces sparkle especially bright.
