After looking at Haiyun's footsteps, he hurriedly turned around the area of the test data center full of computers, and then bypassed a rest area composed of three fabric sofas, and his eyes suddenly opened up.

Except for the array of plants on his side that served as a partition or the frosted glass low wall, Gu Haiyun was in front of him a large open space.

At the farthest corner of the large space, there is a huge metal box surrounded by silver metal walls and various pipelines, and the recessed space on the other side of the metal box has been transformed into an open spare parts warehouse, and several rows of orange shelves extending to the plant partition area are placed with many special accessories for aero engines such as pumps, pipelines, valves, blades, etc.

On the side of the metal box facing Gu Haiyun, there are two pieces of 3M*3M bulletproof glass, Gu Haiyun knows that these two large pieces of bulletproof glass that act as observation windows are 5 cm thick, which can not only resist direct fire from RPGs, but also resist shell fragments below 75mm caliber, and it is natural to deal with engine fire and explosion.

This huge metal box installed in the new gas turbine workshop is the aero engine bench test system that Brilliance Power has been building for two years.

Due to the danger of aero engine testing, generally speaking, major power factories will build an independent workshop as a special workshop for aero engine bench testing.

However, this matter has encountered a little problem on Brilliance's side.

As Liang Yuan has made every effort to promote the application of microelectronic chips in the field of aero engines, the establishment of a new aero engine test data center with high-speed network as the core that can analyze and process a large amount of data in real time has become the goal of Brilliance Power's full construction since its establishment.

The core concept of this test center is to adopt the popular big data concept in the future, and strive to achieve the online diagnosis function of the world's top aero engines in the first decade of the new century in five to seven years.

The so-called online diagnosis means that before the occurrence of aero engine failure, the main chip that controls the operation of the engine will screen and compare the real-time operation data with the large database, so as to prevent the occurrence of micro problems and warn the failure in advance.

After the new century, the service life of the world's top aero engines has been moving towards the order of 100,000 hours, and the concept of the so-called scheduled overhaul is on the verge of elimination.

In addition to the aero engine design from the perspective of easy maintenance, the ultra-large database composed of detailed operation data of various engines is the cornerstone of the existence of the whole system.

Strictly speaking, the development of this set of diagnostic technology actually depends on technological progress in the field of electronics, and before Yuanjia thoroughly understands the single crystal alloy and countless difficult aviation materials of the same pit, it can compete with the international mainstream aero engine in a unique way.

In other words, this is the real hardware is not enough software, relying on technology to achieve corner overtaking.

In the early 90s, the international mainstream power manufacturers just tried to introduce computers into the field of aero engine design, as for the network, big data or anything did not even produce a concept, how could Liang Yuan not grasp the advantages and completely amplify.

The problem is that at this time, the electronics industry is also in the ascendant, and in addition to supercomputers that can process large amounts of data in real time for aero engines, large-capacity optical fiber networks are also the core.

Although Brilliance Power's test data center benefited from the development of the Gangbase supercomputing project to solve these two difficulties, due to the use of a distributed supercomputer, all data sources must be within 60 meters, once the time difference caused by the data entering the various processing nodes of the distributed supercomputing system exceeds 60 meters, there will be conflicts and even collapse of the supercomputing system.

Generally speaking, the range of 60 meters is enough for each computing node in the supercomputing system, but the Brilliance Power Test Center requires real-time processing of aero-engine operation data, which leads to the entire test data center can only be built near the aero-engine test bench that generates data.

Eventually, the large, sturdy metal box was built inside a botanical garden-like gas turbine garage.

Of course, with the advancement of software and hardware technology, the distributed supercomputing system will solve the defect of strict requirements for the connection distance of sub-computing nodes in the future, but Liang Yuan dare to waste time waiting for this, in case he is stuck on this technical threshold for ten or eight years, he will not cry to death.

Seeing Li Yuanling staring thoughtfully at the aero engine that spewed out a few meters long fiery jet on the test bench, Gu Haiyun shook the folder in his hand and walked over quickly.

Out of the corner of her eye, she realized that Gu Haiyun was coming, Li Yuanling gave up observation and reached out to take the document in Gu Haiyun's hand.

"Why did Xiao Gu come over so early, after the shutdown at eight o'clock, I had to stay up all night, and I was afraid that I wouldn't be able to hold on if I didn't sleep much. ”

"When I was dreaming just now, I dreamed that a data was miscalculated, which scared me into a cold sweat, and I didn't feel anything. ”

"Sister Li, where are the Red Guards?"

"My whole group was taken to bed by me and will come over tomorrow morning. ”

Quickly flipping through the documents in her hand, Li Yuanling asked while taking a quick look, "How is the data?"

"So far it's not bad, at this stage, the fuel consumption is 1.07 percent higher than the original, I don't know if it is necessary to continue to run in. ”

Li Yuanling nodded, frowned slightly, and continued to look at the file data in his hand.

"Sister Li, if you count today, we have already completed twenty-one cycles, even if there is a shutdown and overhaul now, this result is revealed, and a large number of people in China will still be frightened. Gu Haiyun said with a bit of pride.

Brilliance Power's aero engine bench test is absolutely super level in China, and the twenty-one cycles in Gu Haiyun's mouth actually mean that the aero engine running in front of the two people has undergone twenty-one stops and restarts.

According to Brilliance Power's aero engine test standard (provisional), each engine model developed by Brilliance Power must complete 28 standard cycle tests before being finalized, and each standard cycle means that the model must run continuously for 12 hours without failure after start-up.

In other words, before the finalization and production of each aero engine model of Brilliance, 336 hours of trouble-free testing must be completed, although it has not reached the requirements of the top power manufacturers in Europe and the United States after the new century must pass the 400-hour test before the model is finalized, but at this time it is only 90 years, and the buildings of GE, Pratt & Whitney, and Rolls-Royce were not built in a day, and the 336-hour long-term test currently carried out by Brilliance is definitely enough to be the top in the world.

"It's not that exaggerated, the first 20 cycle tests of the domestic aviation development finalization are also often done. ”

"Sister Li, what you say is to deceive Dashao's level. ”

Hearing Gu Haiyun mention Liang Yuan, the corners of Li Yuanling's mouth curled up in a curved arc.

A few days ago, because Li Yuanling has been working overtime recently, Liang Yuan called to ask the reason, and was sent away by Li Yuanling with the concept of a common domestic cycle test.

How can Liang Yuan, a two-knife like this, think of the difference between the domestic cycle test and the Brilliance cycle test.

Although the domestic cyclic test is also done for 20 cycles, it is limited to the small short legs of the Republic's fighters, and in addition, during the big movement, the air refueling technology is regarded as the exclusive use of imperialist aggression, so in the circular test of the Republic's aero engine, it is enough for the aircraft to be tested to run for only two hours, and it is meaningless to run for any more time, after all, the republican aircraft can only be equipped with fuel that can run for two hours.

This is also the origin of the need to pass 40 hours of verification before the Republic of China Aviation is finalized.

Whether it is the United States imperialism, British imperialism, or French imperialism, the strategic needs of imperialism are all global deployments, and the transatlantic or Pacific support and warfare like the F14 fighter is a very practical and realistic demand.

The difference in strategic needs has led to the finalization and verification of aero engines in European and American countries, which is based on a six-hour voyage across the Atlantic to support Europe, which has gradually escalated to 12 hours with technological progress and the development of the international situation, and has even become a 24-hour cycle after the new century.

The development and design of the Soviet-style aero engine was based on the design idea of the world war, and there was no need to consider the old Maozi and the Republic of Korea who crossed the ocean to support the global deployment, fell into a pit, and in the eyes of the Soviet Union, the war together did not take more than 20 sorties, and the plane would have been destroyed long ago.

The so-called wrong direction, no matter how much knowledge there is, the reason why European and American aviation engines are calling for wind and rain in the civil aero engine market, and the civil promotion based on military aero engines is fundamentally in the right direction.

If Brilliance Power wants to make a difference in the global civil aviation market, then it is destined to be unavoidable to take the road of imperialism in the research and development of military aircraft engines.

"There is still a week to go, everyone is focused on working hard, and if there are no problems in these seven days, the new fan will be truly finalized. ”

"Sister Li, in fact, this new model also meets the requirements. ”

"The original thrust ratio of Spey aero engine is only 5.05, although we only changed the fan and high-pressure compressor blades, but the intake air flow has increased by 9.7 percent, the five-stage fan has been changed to three-stage, the high-pressure compressor has also been reduced by one level, and the military thrust has increased by 13 percent, which is enough for a new model. ”

In the original design of Spey obtained by Brilliance Power from the navy, the military thrust is 54.5KN, the afterburner thrust is 91.1KN, and the overall mass of the aero engine is 1850KG.

Although Li Yuanling did not move Spey's core machine, he increased the air intake by 9.7 percent on the original basis, adjusted the oil circuit to increase the fuel supply, and the removal of the two-stage fan and the one-stage high-pressure compressor is equivalent to reducing three turbine discs, and more than 200 blades are attached to a small section of bearings, which alone has reduced 190 kilograms.
