In fact, supporting Zhao Wei to reopen a turboshaft engine project is very risky.

Not to mention the investment required in the design team, the various wind tunnels in the design process to optimize the selection of various options, which requires great cost. Not to mention the design itself, the light is the material used, the cost is high enough to make people stunned.

It should be known that the process of this yttrium-containing superalloy is not yet determined and can only be prepared in the laboratory. The cost of R&D and testing that was previously invested is directly one billion. In the case of separate preparation, the cost per ton of material may exceed tens of millions of dollars. It’s just the cost of materials. The cost of a turboshaft engine is probably more than $20 million, ten times higher than the $2 million Black Hawk helicopter engine.

This is only the cost of materials, and the fat man does not mention the processing costs. It should be noted that most of the impellers of this turboshaft engine are manufactured in one piece. Before the matching 3D printing technology has been developed, only the fat man can process this precision.

Perhaps after the completion of the material production process and 3D printing technology, the cost can be greatly reduced, but the current two prototype test samples, the research and development cost investment is more than 1.5 billion yuan. Even if the material cost of the largest head is currently paid by Zhengfang Technology, the state can't always take advantage of the company's cheapness, and it still has to pay. At most, it can be delayed for a period of time.

This is not counting, there is another project of the same type of vortex shaft 9 in China, which is repeated, which is a taboo for research and development.

Under the current situation, it is necessary to spend a lot of money to decisively set up this turboshaft engine, and the leadership of the generals and the final assembly is also under tremendous pressure. On the one hand, they have confidence in Zhao Wei and her team, on the other hand, because Guo Tailai.

A marine turbine engine already has mature products, and the optimization principle of the Black Hawk engine has been discussed. It has great enforceability, and processing technology that is in the process of processing even the most powerful CNC machining centers in China. Let the generals and general assembly leaders have a strong reassurance. Since this is possible, why not try it?

At the end of the day, under the pressure of the top and the parties questioned, the students of the project insisted on more than a year, and got this huge good news before the end of this year.

Although the off-site test has not been done yet, although the operating life has not been calibrated, according to the current test situation and Zhao Wei's estimate, the initial 1000 hours is not a problem. However, this statement is not dare to say that the actual support can only be given by the test bench for a long-term test. Zhao Wei has attached a follow-up test plan after the test report, and will start a 50-hour continuous long-term start next week. Test the car.

While eating a reassurance, the generals were also amazed. Isn't China the first independent production of aero engines? Every time, whether it is introduced or designed by myself, when there is a trial run, there will always be such problems, and there has never been a successful time. Zhao Yi’s design team apparently created a record.

The generals took the test report to the leader's office for reporting. Looking at this test report, the leader looked at it for ten minutes, and the first sentence that looked up was to suppress the surprise and the general asked: "This test report, no problem?"

“The design team was involved in the test process, but the test team was another unit, and the maintenance team was the third unit.” The general gave the perfect answer in one sentence.

Not a unit's test team, is it not necessary to join the design team to make a fake? Moreover, there are maintenance teams of different units. How likely is the collective fraud of the three units? This is a military project, who dares?

The leader stood up, his face with an excited smile, and a few back and forth in the office with his hands on his back and forth. The generals sat on the sofa and could hear the deep breathing in the nose as the leader walked.

"Who can see who can still question this?" The voice of the leader is full of relief and ease, and persists in the final pride: "Who else?"

The generals fully understood the mood of leading the moment. This year, the total military expenditure of the whole country did not exceed 200 billion yuan. In a project, it was thrown into more than one billion. In the face of many doubts, the pressure is not ordinary. It’s good now, and I can finally breathe a sigh of relief.

“Organize a meeting right away!” The leader thought about it and finally stopped to indicate: “The chief of the Wu Zhishi’s chief and unit leaders must participate, as well as the experts of the Army and the Air Force, to assemble here, no! Go to the test site. We encourage our heroes on the spot and work with the engine design team to study the engine installation test plan."

At this time, no one at the scene knew that such a thing would happen. When a group of senior leaders with generals and several non-military figures appeared at the test site, Zhao Wei and others were working with the test team for 50 hours of continuous long-term effect. The test drive has reached the final stage, and it will be completed for the first time in four or five hours.

All the experts who saw the test report felt completely unbelievable and felt incredible. At the moment, they saw the two engines in the actual test site, looked at the series of data curves on the test equipment, and watched the scene at any time. The data they measured and adjusted to measure were all stunned.

The ears are imaginary, and the eyes are seeing the truth. No one now thinks that it is exaggerated. No one thinks that this is a sensation, only the incredible and full of ecstasy.

Every expert who is qualified to stand here is a determined patriot. Who does not want to see the country's independent research and development of self-produced aero engines? In front of these two engines, I am afraid that it is not only the independent development of independent production, the key performance parameters hang the same level of engine of the same type, and our helicopters no longer have to worry about being stuck by others.

The current Wuzhi 10 prototype uses the PT6C series turboshaft engine from Pratt & Whitney Canada. It is definitely impossible for the Americans to set up the card. It is impossible to use it directly after the use. If the domestically produced engine vortex shaft 9 is being developed, the power will be reduced. 20%, it is not enough. But now, looking at this engine with higher power consumption and lower weight, what else can you say? change!

"In the past, we were afraid that the engine power couldn't keep up with some features that can only be regretted. Now it can be added!" The chief engineer looked at this engine, which had not been measured in terms of service life, and his eyes shook like a strange light, as if The bulb is normal.
