Chapter 564: Lin Shengli: Well done, even better than I was when I was young

Lin Zhengcheng let out a breath, a faint smile appearing on his face:

"The first-stage recheck went smoothly, everyone did well. Next, we enter the second stage, pairwise system coordination testing, focusing on checking the smoothness of system interfaces; we must not be careless."

The second-stage test began with the coordination of the avionics and navigation systems.

Chen Mo sat before the avionics console, his fingers rapidly striking the keyboard, issuing control commands; the commands traveled through the transmission channel to the navigation module, while Xiao Zhang stood before the navigation console, real-time monitoring positioning accuracy and command response.

"Avionics command transmission normal, navigation module reception normal, positioning accuracy no deviation, interface smooth." Xiao Zhang reported loudly, his face full of seriousness.

Next came the coordination test between the avionics and cooling systems. Chen Mo sent the engine start command; the engine ran slowly, the cooling system activated accordingly, Lin Zhengcheng stood before the cooling system console, real-time monitoring cooling pressure and temperature, ensuring the cooling system could promptly respond to the engine's cooling needs.

"Engine start normal, cooling system response timely, pressure value 0.008 MPa, temperature normal, interface smooth."

Lin Zhengcheng reported loudly, his tone steady.

The most critical test was the coordination between the stealth coating and the engine cooling system.

Lin Qinhua stared intently at the coating detector; Chen Mo then started the engine, gradually increasing its speed to simulate different flight conditions, the engine's cooling temperature rose accordingly, and Lin Qinhua's heart tightened as well, her eyes fixed on the coating reflectance data on the screen.

"Engine speed increased to 50%, cooling temperature 350°C, coating reflectance 0.01 square meters, normal."

"Speed increased to 70%, cooling temperature 420°C, coating reflectance 0.012 square meters, slight fluctuation, but still within standard range."

"Speed increased to 100%, cooling temperature 500°C, coating reflectance 0.015 square meters, fluctuation amplitude increased, approaching the upper limit of the standard."

Lin Qinhua's voice grew grave as the data changed.

Lin Shengli also came over, staring at the coating reflectance data on the screen, his brows slightly furrowed:

"What's going on? When the speed reaches 100%, why is the coating reflectance fluctuating so much?"

"It should be that the engine cooling temperature is too high, causing the nanomaterial activity in the coating to drop, leading to reflectance fluctuation."

Lin Qinhua quickly analyzed, her fingers rapidly operating the keyboard to adjust the coating monitoring parameters: "I'm trying to adjust the coating's temperature compensation parameter to see if I can reduce the fluctuation amplitude."

Lin Zhengcheng also immediately said:

"Chen Mo, slightly reduce the engine speed, keep the cooling temperature within 450°C; Qinhua, you here speed up adjusting the compensation parameter to find the optimal solution as soon as possible. Xiao Zhang, you help Qinhua verify the parameters to ensure the adjustment is accurate."

"Understood!" Everyone immediately sprang into action; Chen Mo gradually reduced the engine speed, the cooling temperature dropped accordingly, Lin Qinhua focused on adjusting the coating's temperature compensation parameter, while Xiao Zhang stood by helping to verify, daring not to be the slightest bit careless.

Time passed bit by bit; the workshop atmosphere grew tense, everyone's face grave, no one spoke, only the equipment's humming and the sound of fingertips striking the keyboard.

Lin Zhengcheng stood before the console, his gaze shifting between screens, constantly monitoring the data changes, sweat beading on his palms—he knew that if a problem arose in this segment, it would not only affect the joint debugging progress but could also impact the bomber's stealth performance, thereby affecting flight test safety.

Zheng Juan also did not leave, sitting in the workshop corner, clutching a handkerchief, silently praying for the children in her heart.

She didn't understand those complex parameters and systems, but she knew the children were giving their all for the nation's great cause; all she could do was silently guard, handle logistical support, and not let them be distracted.

After about half an hour, Lin Qinhua finally stopped her operation, a hint of smile appearing on her face:

"Adjusted! I optimized the coating's temperature compensation parameter and increased the nanomaterial's antioxidant component; let's test again now."

Chen Mo immediately raised the engine speed, keeping the cooling temperature at 480°C; everyone's eyes focused on Lin Qinhua's detector screen.

"Speed 100%, cooling temperature 480°C, coating reflectance 0.011 square meters, fluctuation amplitude markedly reduced, meets standard!" Lin Qinhua's voice full of joy, her tense nerves finally relaxed.

Lin Shengli let out a breath, patted Lin Qinhua's shoulder, and said with a smile:

"Well done, composed and calm, handled properly, even better than I was when I was young."

Lin Zhengcheng also showed a relieved smile:

"Great, this problem is solved. Next, continue completing the pairwise system coordination tests; we must ensure all systems interface smoothly with no abnormalities." Everyone resumed testing; after over two hours of effort, all pairwise system coordination tests were completed, all systems interfaced smoothly, all parameters met standards, with no abnormalities.

At noon, the joint debugging work temporarily paused; Zheng Juan had already prepared steaming hot dishes: braised spare ribs, stir-fried bok choy, tomato egg soup, and a full pot of millet porridge—all home-style favorites everyone loved.

"Come eat, take a break; this afternoon there's an even more important full-system linkage test, so you need to rest up."

Zheng Juan greeted everyone with a smile, serving each person rice and passing soup.

Everyone gathered around, eating while discussing the morning's joint debugging situation, faces filled with a sense of accomplishment.

"That little hiccup with the coating this morning scared me, but luckily Qinhua reacted quickly and adjusted the parameters in time."

Xiao Zhang gnawed on the spare rib, speaking vaguely: "If that problem weren't solved, the afternoon full-system linkage test would definitely be affected."

"Yeah, Qinhua is indeed impressive, meticulous, and strong in professional ability." Chen Mo nodded, gave Lin Qinhua a piece of spare rib, his tone gentle: "For the afternoon full-system linkage test, you'll need to keep a close eye on the coating side; if any abnormality occurs, report it promptly."

Lin Qinhua's cheeks flushed slightly, she nodded: "Don't worry, I will. Your avionics and navigation systems are the same; during full-system linkage, command transmission and positioning accuracy must not have any issues."

Lin Zhengcheng put down his chopsticks, spoke seriously:

"The afternoon full-system linkage test is the most crucial step, simulating various flight conditions during test flight, including takeoff, cruise, landing, and flight status in complex weather; all systems must work together, no segment can go wrong. After everyone finishes eating, rest twenty minutes, then immediately dive into the testing; we must ensure absolute perfection."
