Chapter 139 Taking Photos of the Aircraft Carrier (Bonus Chapter for Monthly Tickets)

Time flies, and summer vacation is over in the blink of an eye.

The sweltering heat is gradually dissipating. Although the lingering heat of late summer is still raging, there is a hint of early autumn coolness in the mornings and evenings.

Comrade Lin Weiliang and Comrade Zhang Xiali, who had been on a road trip through several provinces and sent Lin Dong travel photos every day, saying how fun this place was and how beautiful the scenery was there, returned home on time yesterday, August 30th, two days before Lin Dong's school started.

"dad."

After finishing dinner, Lin Dong whispered to Lin Weiliang, who had returned from a trip of more than a month and whose complexion and demeanor were noticeably better, and whose newly grown hair seemed to have become darker, "Godfather wants you to come to the lab tonight."

"What are you going to the lab for?" Lin Weiliang looked up.

"I want you to sit in on the proposal."

After Lin Dong finished speaking, he said something to Zhang Xiali and then left the community to go to Laboratory No. 78.

"The option of observing the proceedings?"

talking.

Lin Weiliang, not even bothering to finish his dinner, pulled out a tissue to wipe his mouth and then opened the door to follow him out.

Twenty minutes later.

Lin Dong arrived at the laboratory.

Wang Xingguo and Xu Ziming had already come from the adjacent assembly workshop to wait, and soon after, Lin Weiliang also arrived.

Di-

Lin Dong turned on the lab's server, and the 200-inch screen lit up.

A drawing of an aircraft that resembles the J-20A in shape, but with its canards and main wings integrated into a single unit to form a huge delta wing and more distinct angular edges, appeared on the screen.

"Is this the design blueprint for the WZ-8?"

Wang Xingguo immediately opened his eyes wide and carefully looked at the various details of the aircraft on the screen.

"right."

Lin Dong nodded: "It's not the final design drawing yet, but the plan has been finalized, and the final effect will be similar."

In just over a month, under Lin Dong's impetus, the entire WZ-8 program was officially finalized and entered the final design verification stage.

This is the most tedious step in the entire design process, and also the key step in bringing the design from concept to reality.

Initial technical verification preparation work, scheme determination, design verification.

The current plan only tells people what technologies the WZ-8 will use, what system modules it has, what equipment capabilities it has, what its performance parameters are, and what the approximate size and weight of the aircraft are.

However, the solutions at this stage did not specifically address how to implement these technologies, system modules, and performance parameters.

Only after completing the final design verification stage, can the entire scheme be broken down into actual component manufacturing drawings and process flow diagrams.

Only then is the entire design work considered complete, and can we move on to the next stage of manufacturing and assembly.

If we use a written process as an analogy, the initial technical verification and preparation work is like collecting materials, the solution determination is like writing an outline, and the final design verification is like turning the outline into a complete document.

"The WZ-8 adopts a waverider design, which is a must for hypersonic aircraft."

However, considering the potential need for low-speed reconnaissance in the future, it also retains a tail fin for low-speed directional control.

The external fuselage uses silicon carbide composite material for heat insulation, which can be directly combined with the stealth coating, significantly reducing the weight.

The engine solution uses two pre-cooled variable ramjet engines with a total thrust of 87.3 kN and a maximum takeoff weight, while also achieving a thrust-to-weight ratio of nearly 1.2.

During hypersonic flight, the internal cooling system of the aircraft is directly connected to the engine pre-cooling device.

This allows for electronic regulation of the heat dissipation system, further stabilizing the operation of the precooling unit and reducing its failure rate.

Based on Mach 4 cruising speed, the final cruising range can reach 7200 kilometers from ground takeoff and 9400 kilometers from airdrop with payloads from the H-6…

What?

Wang Xingguo suddenly stood up, and Lin Weiliang and Xu Ziming also widened their eyes in disbelief. The three adults looked at Lin Dong at the same time, as if to confirm something.

"9400 kilometers?"

Wang Xingguo asked in disbelief.

Although he checked emails daily about the project's development progress, he was unaware of data such as the driving range that needed to be calculated.

He had always believed that Lin Dong was designing the aircraft with an 8000-kilometer airdrop range.

After all, this range is already the world's best, among the world's top, and the design difficulty is terrifyingly high.

"right."

Lin Dong nodded, a little regretfully, and said, "I originally wanted to make it 9600 kilometers to match the land area, but no matter how I optimized it, it didn't work. 9400 kilometers is the limit."

"I remember, the WZ-8's detection range for large ships is 300 kilometers..."

Lin Weiliang remained silent for a moment before saying, "So, if the flight path is planned well, and we take into account the distance to the coastline and land, it could reconnoiter and search an area of ​​200 million square kilometers of sea in a single sortie?"

"almost."

Lin Dong smiled and nodded, looking very excited and interested, saying, "Once the research and development is completed, I will build one myself. Then I will go out to sea every day to take pictures of the American aircraft carriers and share their updates."

"..."

Lin Weiliang was speechless at Lin Dong's interest. Looking at the aircraft on the screen, he took a deep breath: "How did you do that? Did you install a nuclear reactor on it?"

Lin Weiliang knew very well that conventional methods could not achieve this level of success.

Lin Dong must have innovated some technology within it to achieve an airdrop range of 9400 kilometers while maintaining a weight of 7.5 tons.

But there's a problem.

He only went on a trip for a little over a month, not ten years. How come his skills have changed so much in the blink of an eye?

"Um... gallium nitride!"

At this moment, Wang Xingguo seemed to realize something, turned to Lin Dong and said with some shock, "...Is the enhancement effect on reconnaissance equipment like radar really that exaggerated?"

"Incredible! For the same radar performance, the equipment size is reduced by an average of 86.2%, the weight by an average of 48.9%, and the power consumption by 45%..."

In other words, disregarding weight, the performance of the equipped radar can be improved by approximately 10 times within the same space.

Lin Dong nodded and said seriously, "But this gallium nitride radar and the complete set of reconnaissance equipment are not yet in use."

I had already figured out the basic mass production technology for gallium nitride by early August, and now we are waiting for the chip suppliers and radar component manufacturers from the electronics industry to start production.

"Godfather, you need to urge them on this. If they keep dragging their feet, we'll just build it ourselves."

"We can even build our own radar?" Wang Xingguo asked, his expression momentarily stunned.

"certainly."

Lin Dong casually opened a radar manufacturing process flowchart and carefully analyzed each step, saying, "We can synthesize gallium nitride directly in the laboratory, and the cost difference for small-batch production is not significant."

This antenna substrate is quite challenging. We don't have equipment big enough for it. Splicing it into segments would result in a 10% performance loss, but we can compensate by making the segments larger.

For chip mounting and stable control base, our Chengdu Aircraft Industry Group's processes are more than sufficient, and the gold wire bonding laboratory can also complete them.

Initially, the lab would manually manufacture each set according to the established procedures, taking about a month to complete. Later, with standardized components and readily available equipment, several sets could be made per day.

"The most important aspects of radar are signal tuning and algorithms..."

Wang Xingguo said instinctively, but shut up before he could finish.

Because he knew how freakish Lin Dong was when it came to debugging and algorithm-related technologies. In his words, he could directly "see" where there was a problem with the equipment or where there was a defect in the algorithm.

Although the actual debugging of the radar requires a microwave anechoic chamber, the synthetic aperture radar this time is not very large, so Chengdu Aircraft Industry Group was able to easily find the resources.

"I'll go and urge them."

Looking at Lin Dong's serious expression, which didn't seem like he was joking, Wang Xingguo rubbed his forehead and said helplessly, "I'll take a military plane tomorrow and go to their door to urge them."

As for doing it ourselves, we'll avoid doing it if we can.

If they really can't handle it, then we'll take over... After all, Chengdu Aircraft Industry Group (CAC) can't do all the work, and we don't have that many employees or that much space.

"Alright, Godfather, it would be best if you came to urge us."

Lin Dong casually printed out a list: "The synthetic aperture radar is from the 607 Institute of CETC in Jiangsu, and the electronic reconnaissance equipment is from the 51 Institute of CETC in Shanghai."

High-precision infrared instruments, optoelectronic instruments, hyperspectral imagers, and high-resolution visible/infrared cameras are all products of the Xi'an Institute of Optics and Precision Mechanics.

As for the remaining laser rangefinder, we made that ourselves. In recent years, Chengdu Aircraft Industry Group (CAC) has been number one in the domestic laser research and application field, and my father is an absolute authority…”

"..."

Lin Weiliang's lips twitched; he had absolutely no desire to deal with this unfilial son.

Holding the list handed to him by Lin Dong, Wang Xingguo said with a wry smile, "After decades of building aircraft, we've unknowingly become the No. 1 in the laser device field..."

"Alright, that's the general plan for the WZ-8."

"Over the next few days, I will break down the plan, start distributing tasks to the labs below, conduct final experiments and tests, and design the verification process. Godfather, come back soon, otherwise it will be inconvenient to use your email."

After Lin Dong finished speaking, he waved his hand, opened the door, and walked outside: "You adults can chat anytime. I'm going back to sleep now. I'm starting junior high tomorrow..."
