Genius of the Rules-Style System

Chapter 797: Chapter 428: It’s Too Early to be Excited Now!

The maximum temperature a turbine blade can withstand is a crucial indicator of turbine engine technology.

Ordinary turbine engine blades must bear temperatures above 700 degrees Celsius, and most turbine blades are made of nickel-iron alloy. The melting point of nickel-iron alloy, based on different alloy formulations, fluctuates around 950 degrees Celsius.

The standards are higher for aviation turbine engines. The higher the temperature turbine blades can withstand, the better, and the maximum thrust of the engine directly depends on this temperature.

For instance, the F119 engine of the M country’s F22 fighter jet has a turbine inlet temperature of about 1700 degrees Celsius, which gives the engine a hefty thrust of 15.6 tons.

The turbine inlet temperature of Country E’s AL31F engine sits around 1400 degrees Celsius, generating thrust worth 12.5 tons.

Our domestic high-end fighter planes are equipped with the 99M1 engine, which is the second batch of imported AL31F engines. The turbine inlet temperature clocking in at 1420 degrees Celsius, affording a maximum thrust of 13.5 tons.

According to an international formula, under the prerequisite of the identical design level of engine turbines and fans, for every 100 degree Celsius increase in turbine inlet temperature, the maximum thrust increases by fifteen percent.

The previous highest temperature the K03A could withstand was 1250 degrees Celsius. Now, with a melt point increased by one hundred degrees Celsius, it has reached 1350 degrees Celsius.

Although this number cannot catch up with the international advanced level, it doesn’t fall far behind the imported high-end turbine engines.

He Guilin and the entire research and development team were thrilled at validating the data. They excitedly discussed, "An increase of one hundred degrees! We’re almost catching up to the performance of high-end engine blades!"

"We’re so close!"

"I really didn’t expect that a change in one mid-level process could yield such an excellent result. The K03A hasn’t shown progress in over a decade, but now it’s taken a significant leap forward! With this data, I assume, both Kunlun and Wangwu engine project will no longer suffer from blade issues. We can manufacture them directly!"

"Right, let’s write a report, let’s write a report!"

"Shall we make it public?"

"Of course, this is a significant breakthrough. It needs to be publicized. However, I’ll consult with the leadership first..."

There’s no need to keep the progress of K03A secret because it doesn’t exceed international standards. It still falls short when compared to the material of imported high-end engine blades.

The joy among the R&D team of 307 Steel Factory stems from the leap in progress that K03A has suddenly taken. This improvement presumably satisfies the demand for domestic engines, not just out of patriotic sentiment but also considering the pressure from superiors.

K03A’s performance has always been an issue and hasn’t seen any progress.

The metal research institute within the Science Academy and Capital Aviation Material Research Institute have always been researching the latest Single-Crystal Nickel Alloy. They’ve regularly achieved results, like DD5 and DD6, both melting above 1100 degrees Celsius and exhibiting excellent strength. If research continues, it seems K03A is about to be replaced.

This thought leaves the research team feeling irrelevant.

Although they haven’t produced any related results, each member of the team feels a sense of frustration.

Now that an improvement has been seen in K03A’s performance, with a jump of a hundred degrees Celsius in melting point, they all feel relieved, as for a short while, they won’t feel any pressure, and they won’t have to worry that "external research findings" will replace K03A.

Team members from the steel factory research team returned to their office, He Guilin assigned tasks regarding the report and subsequently held an internal meeting to discuss Zhao Yi’s following suggestions for improving the K03A manufacturing process, "From now on, everyone will be busy, and I will assign duties."

"We need to verify the improvements suggested by Academician Zhao as promptly as possible, every single one should be validated, all should be validated together."

"This is currently the most crucial task!"

"Do you understand?"

...

At the same time.

Metal Research Institute of the Science Academy.

Academician Peng Engui’s team was also discussing the latest achievements in turbine blade research. They developed a new high-strength heat-corrosion-resistant nickel-based single-crystal high-temperature alloy, which not only boasts excellent heat and corrosion resistance, but also exhibits high mechanical properties at elevated temperatures and excellent structural stability.

The team published their findings in the domestic "Material Alloy" journal, Peng Engui accepted an interview from an academic reporter, and several researchers and students of Peng Engui sat by his side.

Peng Engui sat in the central position, introducing the nickel-based single-crystal high-temperature alloy, "This new nickel-based alloy material has a melting point around 1150 degrees Celsius, fifty degrees higher than DD5. It has excellent corrosion resistance, similar strength to DD5, and can be used in high-temperature components of land and naval gas turbines, as well as high temperature components of aerospace and aeroengines."

The reporter asked, "As far as I am aware, the ultimate goal of developing single-crystal nickel alloys is to apply them to aviation turbine blades. Can this new alloy material be used for aeroengine blades?"

Peng Engui paused and then used a term, "Extremely close!" freeweɓnovel.cѳm

He explained, "Right now, for instance, the Kunlun engine uses K03A nickel-iron alloy, which is technology from over a decade ago and has limited potential for further research."

"The strength of K03A is acceptable. It can withstand a maximum temperature of 1250 degrees Celsius."

"As you mentioned, our ultimate purpose of researching single-crystal nickel alloys is to hope to develop an alloy capable of withstanding higher temperatures and having greater strength. That is, it can be used for aeroengine blades. The new nickel-based alloy can withstand 1150 degrees Celsius, only a hundred degrees Celsius short."

"In terms of the material properties of aeroengine turbine blades, a difference of a hundred degrees Celsius is still significant, but something should be noted..."
