Chapter 563

Just as dawn was breaking, the thin mist of deep autumn had not yet dispersed, the gate of the Research Workshop was pushed open, Lin Zhengcheng entered first, still carrying the morning chill, holding an insulated bag—that was the breakfast Zhang Xiaoran had sent early that morning, still warm, containing two meat buns, a cup of soy milk, and a small plate of pickled vegetables she had made herself, crisp and refreshing.

He did not eat breakfast right away, but went straight to the front of the fuselage, his gaze slowly sweeping over this stealth bomber that was just taking shape.

The silver-gray skin showed a matte sheen in the morning light, the engine cowling was tightly sealed, the fuselage lines were sharp and smooth, every joint of the skin was flat and smooth, every bolt was tightened evenly and firmly.

This was the result of countless days and nights of hard work, the crystallization of the team's joint effort, and moreover the hope of breaking through the United States' technological blockade; as his fingertips lightly brushed the skin, that heavy sense of responsibility and pride once again spread in his heart.

Not long after, Chen Mo, Lin Qinhua, Xiao Zhang and others arrived one after another, each face showing some fatigue, the red bloodshot in their eyes not yet faded, yet everyone was full of spirit, hurrying to their respective posts.

Although yesterday's basic debugging went smoothly, everyone knew that today's comprehensive joint test was the real trial—it required the avionics, navigation, cooling, stealth coating and all other systems to work together; any lapse in any link could cause the joint test to fail, and even affect the subsequent flight test plan.

"Everyone, make a brief preparation; in ten minutes we will officially start the comprehensive joint test."

Lin Zhengcheng walked to the console, opened the computer, called up the joint test procedure list, his tone calm and firm: "The joint test consists of three stages. First stage: independent recheck of each system to ensure each is in optimal condition; second stage: pairwise system cooperation testing, focusing on the smoothness of system interfaces; third stage: full-system linkage testing, simulating various flight conditions to ensure all parameters meet flight test requirements. Remember, every datum must be recorded in detail, every abnormality must be reported promptly, absolutely no negligence."

"Understood!" everyone replied in unison, immediately diving into the pre-joint test preparations.

Lin Qinhua reconnected the detector to each monitoring point on the fuselage stealth coating, carefully checking the instrument's connections to ensure smooth data transmission;

Chen Mo led the team in a final recheck of the avionics system, repeatedly testing the command transmission channels, confirming no stalling, no delay;

Xiao Zhang, together with the technicians, checked the navigation system's satellite signal docking, calibrated the positioning parameters, making full preparations for the joint test.

Lin Shengli also arrived early at the workshop, holding a notebook, with Zheng Juan following behind—she carried an insulated bucket filled with hot ginger tea and steamed buns, a breakfast specially prepared for everyone.

"Kids, eat something first to fill your stomachs; the joint test consumes energy, don't go hungry."

Zheng Juan smiled as she set the insulated bucket on the makeshift table, handing out ginger tea and buns to each person: "You worked late yesterday and came early today; you must look after your health—your body is the foundation of revolution."

Lin Zhengcheng took the ginger tea, sipped a mouthful; the spicy warmth slid down his throat into his stomach, dispelling the morning chill and the fatigue of recent days.

He picked up the meat bun Zhang Xiaoran had sent, took a bite; the fresh, fragrant broth spread in his mouth, the familiar taste warming his heart.

"Thanks, Mom." He said with a smile, his eyes unconsciously falling on the bookmark in his pocket, recalling the message Zhang Xiaoran had sent him last night, the corners of his mouth involuntarily turning up.

Chen Mo and Lin Qinhua also came over, picking up buns and ginger tea, eating while discussing possible problems that might arise during the joint test.

"My biggest worry is that the coating, during full-system linkage, will be affected by engine cooling, causing its reflectivity to fluctuate."

Lin Qinhua took a bite of the bun, her tone tinged with concern: "During yesterday's basic debugging, even under high-temperature simulation the fluctuation was minor, but in full-system linkage the engine cooling will be more pronounced, the temperature higher, so there might be a change."

"Don't worry, I've already communicated with Xiao Zhang and the others; during the joint test we will monitor the engine's cooling temperature in real time, and if it exceeds the threshold we will immediately adjust the cooling system's parameters to keep the coating in a suitable temperature environment."

Chen Mo set down the ginger tea, speaking firmly: "Moreover, we optimized the coating's formulation yesterday; after adjusting the proportion of nano aluminum oxide, the coating's high-temperature resistance has improved somewhat, so it should be able to cope with the impact of engine cooling."

Lin Zhengcheng listened to their discussion, nodded and said:

"Qinhua's concern is quite reasonable; the coating's stability is key to stealth performance and must not be taken lightly. Chen Mo, you need to focus on the coordination between the avionics and navigation systems, ensuring control commands are precisely transmitted to the navigation module so positioning accuracy is unaffected. Xiao Zhang, you are responsible for monitoring the navigation system's positioning error during full-system linkage; if any deviation occurs, correct it immediately."

Ten minutes later, preparations were complete, everyone in position, monitoring instruments all activated, the screen filled with dense parameters; the workshop fell silent instantly, leaving only the faint hum of the instruments and everyone's steady breathing.

Lin Zhengcheng took a deep breath, walked to the console, and lightly pressed the joint test start button with his fingertip—the comprehensive joint test officially began.

First stage: independent recheck of each system.

Lin Qinhua kept her eyes on the coating detector's screen, monitoring in real time the coating's reflectivity at different temperatures—from room temperature to high temperature, from dry to humid—recording each set of data in detail and accurately.

"The coating's reflectivity is normal: 0.008 square meters at room temperature, 0.01 square meters at high temperature—both meet the standard, with no abnormal fluctuation." She reported aloud while recording, her voice tinged with relief.

Chen Mo's team meanwhile conducted a recheck of the avionics system, repeatedly testing the transmission of communication and control commands—once, twice, three times… each test they carefully recorded the command response delay, ensuring no stutter.

"Avionics system recheck complete: communication normal, control command response delay 0.003 seconds, meets standard, no abnormality." A technician announced loudly, a smile appearing on his face.

Xiao Zhang and the technicians also completed the navigation system recheck, simulating positioning accuracy under various simple conditions; the error was kept within 0.5 meters, fully meeting requirements.

"Navigation system recheck complete: positioning accurate, no abnormality."

Xiao Zhang held the recheck report, quickly walked to Lin Zhengcheng's side to report; although the wound on his hand still ached faintly, his eyes were full of determination.

Besides these, the cooling system, fuel system, and weapons mounting system also successively completed independent rechecks, all parameters meeting the standard, with no abnormality.
