"Evacuate everyone." Professor Zhao gave an order outside, and after fixing the engine, all the staff immediately evacuated.

There will be no reservations in the test room.

Because it is a new engine, a new design, and the performance test of many components has not been done, so most people still have to leave a safe distance, because no one knows whether it will explode directly or something, of course, the possibility of this is extremely low.

But for safety reasons, everyone was in the safe house next to it during the test drive.

The overall design structure, Zhao Lao has also seen it, and it knows that there is no problem, so the explosion is estimated to not explode.

But how long it can last without problems is really uncertain.

Such a professional engine test place, even if it really explodes, it can be handled, these places have been professionally designed, no one knows whether the new engine will have such a thing, including the engine designed by Taihang, the new engine test is the same process.

"Ignition!" With Zhao Lao's order, Jiang Yanhai didn't grab the button for the first test drive, there was no need, he just cared about the result, and he didn't care about the process.

When Zhao Lao pressed the button, the entire engine immediately let out a roar, and then its tail instantly erupted with huge flames, and everyone's emotions instantly became tense.

"The test ignition was successful! At present, the state is running smoothly. ”

"The power output is smooth! The structural strength data of the body is stable! ”

"The body is in good shape! Smooth fuel output! ”

"No structural hazards have been found at the moment!"

"The data of each sensor is normal!"

Professor Zhao didn't speak, but quickly walked to the side and quickly checked the electronic screen where he could view all the data.

A minute later, Professor Zhao stood up with some excitement: "I announce!" The test run was successful! ”

"Wow!" Everyone in the operator couldn't help but cheer loudly, followed by a round of applause!

Although they didn't do anything and just produced it, they were also very excited when they saw a new engine successfully tested.

Because no matter whether it succeeds or not, as long as we continue to research, as long as we continue to experiment, then sooner or later it will have new results! Aren't countless researchers making these results little by little in this process?!

Engaging in scientific research is not about doing arithmetic problems, you can get the answer by directly following the steps to solve them.

Countless scientific research is to look for the unknown in the known, look for the impossible in the possible, and explore the direction that human beings have not yet discovered.

"Xiao Jiang! It worked! Seeing that Jiang Yanhai didn't seem to be too excited, Professor Zhao also walked over and repeated.

"I knew that we were short on time and had a heavy task, so we were going straight to a long test run and at the same time testing the data on the maximum thrust and other related aspects. If there is no problem, just let them start producing a second, or even a third. ”

"We still have life test, 150 hours of long-term test, destruction test and other test work to do. One engine is certainly not enough. Jiang Yanhai spoke very simply.

Isn't it a matter of money anyway? Money is not a problem now, after having that material, it is normal for an engine to smash tens of billions, and Jiang Yanhai's current progress is ...... Is this called smashing?

No, it's not even money spent! You must know that the engine mentioned above is tens of billions, which is purely spent in the research process.

As for the shape manufacturing itself, it is not considered a research expense.

Professor Zhao hesitated for a moment, but he still nodded directly, "Since you are confident, of course we have no problem, we can start now, let's test its maximum thrust first." ”

"Attention everyone, the maximum thrust test will start next, and the fuel output will be adjusted to the maximum after 10 seconds of countdown, everyone should pay attention to the data, and report any abnormalities as soon as possible!"

"Yes!"

"10, 9, 8......" Professor Zhao is constantly counting down, and the buttons to control the fuel output of the engine are also increasing.

The fuel output is not unlimited, it has a limit, and this limit, after being installed on the fighter, is when you push the throttle valve to the maximum position!

It's like you were in the car and you just pressed the gas pedal to the end.

As the fuel output continues to increase, you can see from the video that the flame at the rear of the engine gradually begins to lengthen, and then the color becomes more hot!

"Fuel output to the maximum, debriefing!"

"Smooth power output!"

"The structure of the airframe is stable!"

"The body is running smoothly!"

"All sensor data is normal!"

"Report thrust data!" Professor Zhao's tone trembled slightly.

"Report! The current thrust data is 177 kN! The inspector over there, who was measuring the maximum thrust data, was also a little trembling in his tone.

"Great!" Professor Zhao couldn't help but wave his right hand directly! 177 thousand NN! That's equivalent to more than 18 tons of thrust!

That's a lot of thrust! You have to know it's small! It's a little more than a third smaller than the latest WS15A engine currently used on the J20!

It weighs less than three-quarters of the WS15A engine, and it weighs just over 1 ton, so it can almost be said that it weighs only 1 ton! The thrust-to-weight ratio has reached a terrible 18! If this number is said, it is estimated that it will be against the sky!

"Test its middle thrust!" Professor Zhao held back his excitement and said quickly.

The so-called intermediate thrust, that is, the thrust of the engine running smoothly, and the maximum thrust just now, that is, the afterburner thrust, is the maximum thrust of the engine's fuel output, which is commonly known as afterburner when put on the fighter.

And the intermediate thrust data affects the cruise capability of the fighter.

The fuel output power is immediately adjusted, and when the fuel output is stabilized, the intermediate thrust also comes out.

"Report! It has a thrust in the middle of 152 kN! The operator over there gave a number that made everyone cheer.

152 kN is 15.5 tons of thrust, and if it is double-engined, it is a full 31 tons of thrust!

According to the calculation of J20, it has an empty weight of 17 tons, and the air combat weight is 25 tons, according to the calculation of 25 tons, this data is enough for it to cruise at supersonic speed and not be slow, not to mention that its maximum thrust reaches 18 tons.

And there's the volume of it! Volume! The reduction in its size means that the J20 can have more space to enlarge the magazine and other aspects of the design.

"However, it doesn't seem to be up to what we intended." An operator couldn't help but remind.
