This engine, from the inside to the outside, from the turbine impeller to the smallest screw, including the control chip, is all domestically produced.

More importantly, all materials, from turbine shaft materials to integrated impeller materials, are all domestically produced.

Even all the designs have been optimized by domestic technicians based on the Black Hawk engine. In addition to the most basic principles, they have been completely different.

It can be said that this is a pure domestic product. In formal language, this is a domestic turbine shaft engine with completely independent intellectual property rights.

More importantly, the design performance of this engine is so excellent, making people full of unlimited expectations.

The Black Hawk engine itself is the best helicopter engine with excellent plateau performance. It is not only equipped with the Black Hawk series helicopters, but also the core power of the Apache armed helicopter.

This engine is 50 more than the t700ge701c Black Hawk helicopter's 1341 kilowatt power, 20 weight reduction, 25 fuel savings, and more than 50 sub-components. The reliability and maintenance performance are directly improved by one level.

Intuitively speaking, using this engine on the Blackhawk helicopter can increase the range by 161.

Payload more than doubled.

Similarly, the Apache improvements are equally jaw-dropping, with a new engine that can increase its range by 115.

Ultimately, the new engine may mean that the Blackhawk can be equipped with 10 more warriors or 93 shells, while the Apache can increase its flight time by 79 minutes.

It can be said that the performance of this engine will surpass all existing engines in the world, and it is no exception to describe it as the world's number one in the same specification.

If our Martial Arts Ten can use this engine, we may have to face an embarrassing situation, that is, the design performance of the helicopter itself is far from being able to bring out the performance of this engine. We may have to redesign it, or design an armed helicopter or general-purpose helicopter with better performance.

However, these are expected performance, and all of this is based on the successful completion of this engine meeting the design performance requirements.

And the success of ignition is the basis of all this.

Now that the ignition is successful, it means that the most important step has been taken.

Everyone was excited, their eyes focused on the engine that looked normal, and they looked at it without blinking, and no one wanted to look away.

The engine runs smoothly without changing its power without any abnormality.

It was not until thirty minutes later that Zhao Yanyan closed again.

Overall testing is a rigorous and complex process, very cumbersome.

You should know that the stable operation of the engine is related to the performance and safety of the helicopter in the sky, and no one can be careless.

For this test, in addition to Guo Tailai and Zhao Yanyan working hard, the entire design team and testing team also have a maintenance team to prepare a few months ago to ensure that the engine can be launched on the ground interview table and ignite the fire immediately as soon as the engine arrives.

The test steps are very cumbersome, with normal ignition and smooth operation. Will there be problems with the "throttle" being increased or reduced? Can it support ten minutes, thirty minutes, one hour, three hours or even longer.

After each test, you must maintain and check to see if the turbine shaft has deformed, whether there are cracks in the impeller, whether the creep during operation is reasonable, and whether it has affected the overall performance. You must be very careful and strictly inspected at every step.

This is still a ground-based interview. In addition to testing the stability of the engine operation, performance calibration tests are also required to test continuous power, intermediate power, emergency power, maximum continuous fuel consumption, intermediate fuel consumption, power-to-weight ratio, turbine inlet temperature and other series of parameters.

During the engine test, various emergencies such as engine turbine blades may also occur, such as breaking of the blades, breaking through the receiver, engine oil leakage, and test line failure.

All of these require on-site adaptability and quick response, and a strong maintenance team is also very necessary.

Fortunately, this team has started to practice model simulation a long time ago and can stand up at any time.

Possible failures also require a lot of testing space and maintain sufficient safe distance.

This is also one of the main reasons why Guo Tailai’s studio cannot be used as a testing place.

In addition, every inspection test must also record the cumulative life.

Although the material has been tested for a long time and its cumulative service life is as long as thousands or even tens of thousands of hours, in actual applications, it is still necessary to record the cumulative service life. This test cannot be calculated and estimated. It is said that the life is 10,000 hours, so it depends on the operation of 10,000 hours to draw conclusions. How to calculate and estimate other things is not as convincing as this one.

Of course, a long-lasting test drive program is usually used, with 1:1 hours of benches and field.

There are other methods, but they all need to be calibrated for a long time.

This alone can show the gap with foreign countries.

The cumulative service life test of 10,000 hours will take more than 400 days even if it comes up and keeps turning.

But is this possible?

Obviously it is impossible. Each time, it only takes a few hours or dozens of tests to stop and enter the semi-disassembly maintenance and inspection state. Even if it is an average of three hours a day, it will take 3,333 days to draw this conclusion, more than nine years.

Or if the test time doubles, a high-intensity test of six or even ten hours a day will take at least three years.

In other words, it takes several years to launch a new engine, which claims to have a lifespan of 10,000 hours from the start of the engine's ability to reach a lifespan conclusion.

Why do foreign aircraft engines have advantages over domestic ones? They have decades of first-mover time than us. This stable operating life alone requires catching up.

"Sixty minutes of continuous running time!"

"Remaining power less than thirty minutes, 2000 kilowatts!"

"Continuous power, 1860 kilowatts!"

“Emergency power, 2170 kilowatts!”

"Continuous fuel consumption rate..."... After the maintenance semi-disassembly machine is detected, it is installed again and started, and the testing instruments are connected for testing. Data begins to be released one by one.

With each data release, the enthusiasm in the designer and testers' hearts increases by one point, which also means that success is closer.

The things made by Guo Tailai himself were indeed extraordinary. At first, everyone was careful, but after holding a simple material and parts test report and carefully testing it for two days, everyone found that this engine was really powerful.

After a simple communication between Zhao Yanyan and Guo Tailai, it was decided to increase the test intensity and increase the test time every day, striving to obtain the data of the ground interview as soon as possible, and then enter the field installation test stage as soon as possible.

A week later, the test data of the preliminary ground interview bench was released. In addition to the fact that the operating life has not been calibrated, three consecutive failure-free runs have been completed for fifteen hours. The excellent performance makes people want to change the clothes immediately.

The preliminary test report was immediately delivered to General Chu, who was the chief assemblyman. Seeing this report, General Chu could no longer sit still.
