Chapter 135 Gallium Nitride, A God-like Figure in One Battle

Lin Dong was calculating how to fit all these devices of this size and weight into the fuselage of the WZ-8 while ensuring sufficient fuel space, engine location, and low-speed stealth design.

It simultaneously meets the speed requirements of an altitude of 4 meters, a cruising speed of Mach 4, a maximum speed of Mach 7, and a ground takeoff range of 6000 kilometers...

How should the airframe structure and external aerodynamic layout of the WZ-8 be designed?

Ten minutes or so passed.

The first design for the fuselage structure and aerodynamic layout was completed.

Lin Dongbi paused for a moment, looked at the calculated parameters and data, frowned, and then flicked his wrist, striking out a large cross.

This plan leaves too little room for fuel consumption.

The maximum range from ground takeoff is only 4300 kilometers.

Lin Dong thought about it carefully, then started writing down the new formulas and data on the paper, beginning the second round of verification...

Twenty minutes later, Lin Dong put down his pen, looked at the calculated parameters and data, and frowned.

"5300 kilometers... that's the limit."

His perception through his soul vision told him that this range was the limit for the current 12-meter size and 7.5-ton weight.

To improve further, you either need to increase the weight or increase the size.

However, with the increase in weight and size, the WZ-8 can no longer be mounted on the H-6 bomber, and the advantage of an extra 2,000 kilometers of air-dropped range cannot be fully utilized.

"Does this mean we should abandon the low-speed stealth design and, like the brand-new Hot Air, create a purely hypersonic reconnaissance aircraft?"

Lin Dong picked up a pen and did a quick calculation.

If the low-speed stealth design is removed, some weight can be reduced in the body, while also increasing the body space.

This approach, which combines open source and cost-saving measures, allows for a range of approximately 6200 kilometers, which is sufficient to meet reconnaissance range requirements.

"This is my first time leading a research and development project, and it has to be perfect without any flaws..."

Lin Dong thought for a moment, then set aside the plan that removed the low-speed stealth design and wrote a name heavily on a piece of confidential white paper.

Gallium nitride!

Gallium nitride is the key cornerstone that has changed the situation in which China's radar technology, optoelectronic technology, and electronic reconnaissance technology have lagged behind the United States.

This technology, combined with the rare earth resource advantage of gallium, is a key advantage.

In later generations, China directly dominated the world in fields such as radar and electronic reconnaissance, with no rivals around it.

In the 1990s, the United States used a Growler electronic warfare aircraft to break through the defenses of the entire eastern coastal region of the country.

After the J-16D, which uses gallium nitride technology, was born, the "Roaring One" was transformed from an electronic air overlord into a whimpering one with its tail between its legs.

In a covert electronic warfare engagement that took place at sea in later years, a domestic J-16D fighter jet chased down three opposing Growler fighter jets.

That day, over the entire ocean.

Apart from ships equipped with Beidou navigation systems, all other ships using GPS navigation systems became blind, and could only wander around in circles at sea.

Apart from domestic wireless communication frequencies, all other communication channels in the sky were blocked, and only bursts of electronic noise could be heard.

On that day, the J-16D achieved legendary status in one battle, becoming invincible.

"Gallium nitride, that's familiar to me."

"The chargers I used in later generations were all these things..."

Lin Dong muttered to himself, picked up the water that Xu Qingling had quietly poured and took a sip. He then carefully looked at the various emails that had just been sent, noting the dimensions and weight of the components on them.

Gallium nitride is known for its formidable performance in optoelectronics and electronics, as well as its thermal conductivity, which is many times stronger.

If gallium nitride technology can be mastered, then these reconnaissance aircraft must be equipped with synthetic aperture radar, electronic reconnaissance instruments, high-precision infrared instruments, optoelectronic instruments, hyperspectral imagers, and high-resolution visible/infrared cameras.

Aside from requiring the use of a high-resolution visible light/infrared camera with a lens group, the optimization effect is relatively average.

Other instruments, without changing their performance, can all be reduced in size to one-third to one-tenth of their original size, and their weight can generally be reduced to one-half to one-third of their original weight.

So much weight and size have been reduced.

With the WZ-8's range, it can be optimized to more than 7000 kilometers from ground takeoff in no time.

Not only does it meet the project's requirement of 6000 kilometers of range, but it also provides an additional 1000 kilometers.

"But this stuff is difficult to get right now..."

Lin Dong frowned slightly, his right hand about to write but then stopped.

Gallium nitride is a simple material to manufacture optoelectronic and electronic instruments.

The performance improvement is so dramatic not because of the technology itself, but because of the exceptional performance of gallium nitride.

However, the problem is that manufacturing gallium nitride itself is not simple.

Like third-generation single-crystal nickel-based alloys, this thing is a single-crystal material, which is not suitable for ordinary production methods.

Even though gallium nitride will become ubiquitous in the future, and every household can buy a gallium nitride phone charger, this small device can achieve 100 watts of charging.

However, in 2012, how to produce high-purity gallium nitride was still a major challenge in the field of materials science.

Lin Dong carefully recalled the reports about gallium nitride from his previous life.

Because of its application in the field of electronic semiconductors, gallium nitride was once promoted by many mobile phone manufacturers as a major selling point.

Thanks to these experiences, he gained a certain understanding of the gallium nitride manufacturing process.

However, in his calculations, the third-generation single-crystal nickel-based alloys mainly rely on the Czochralski growth process, while gallium nitride relies on the vapor deposition process.

"The conventional method is the same as silicon carbide, using a vapor deposition process."

"To produce large-size single-crystal wafers, we need the molecular epitaxy technology reported in the previous life... but for radar devices, the vapor deposition process is sufficient."

"Yes, vapor deposition process... I'm very familiar with it."

Thinking of this, a hint of surprise appeared in Lin Dong's eyes.

While helping to advance the third generation of single-crystal nickel-based alloys, he gained an in-depth understanding of various materials science-related knowledge and single-crystal material manufacturing processes.

Although I am not familiar with molecular epitaxy technology, which only came into existence in later generations.

However, they have considerable expertise in the three conventional processes: vapor deposition, Czochralski growth, and high-temperature, high-pressure growth.

Otherwise, it would be impossible to analyze and verify the third-generation single-crystal nickel-based alloy, which requires the Czochralski method and gradient temperature control.

Moreover, at that time he was preparing to design a brand new Hot Hot, and was considering using silicon carbide with vapor deposition process as the stealth coating for Hot Hot. He had also conducted in-depth research on the vapor deposition process.

"Yes, we should go back and focus on studying gallium nitride materials. Combined with our existing knowledge of vapor deposition, we should be able to find a solution soon..."

Lin Dong has never doubted his learning ability and technological breakthroughs.

It's open now, after all.

One effect of Soul Vision is that it enhances abilities such as memory, concentration, and comprehension.

One effect can perceive the flaws and balance of everything, directly finding the thread that hides the perfect path among thousands of threads.

Because there were no technical obstacles for him, and he had a clear idea and direction, he was confident in his solution.

Lin Dong didn't delay any longer and directly recalculated a preliminary plan for the fuselage structure and aerodynamic layout of the WZ-8 based on the accurate prediction of gallium nitride devices.

After confirming with Wang Xingguo that no one else was in the office, he began editing emails, breaking down the plan and assigning it to departments and laboratories under Chengdu Aircraft Industry Group. He started arranging various stress tests and wind tunnel tests for components, collecting data to improve the overall plan.
