"Everyone evacuates." Professor Zhao gave the order outside. After fixing the engine, all staff evacuated immediately.
No one will be retained in the test workshop.
Because it is a new engine, a new design, and the performance testing of many components has not been done, so most people still have to stay away from a safe distance, because no one knows whether it will explode directly, and of course the possibility of this is extremely low.
But for safety reasons, everyone was in a safe room nearby during the test drive.
Old Zhao has also seen the overall design structure and knows that there is no problem, so the explosion is probably not going to happen.
But it's really hard to tell how long it can last without problems.
A professional engine testing place like this can handle it even if it does explode. These places have been professionally designed. No one knows whether such a thing will happen to new engines, including engines designed by Taihang. The testing process of new engines is the same.
"Ignition!" Following Old Zhao's command, Jiang Yan Hai did not grab the button for the first test run. There was no need. He only cared about the results, not the process.
When Old Zhao pressed the button, the entire engine immediately roared, and then its tail instantly sprayed out a huge flame, and everyone's emotions instantly became tense.
"The test ignition was successful! The current status is running smoothly."
"The power output is stable! The structural strength data of the body is stable!"
"The airframe is in stable condition! Fuel output is stable!"
"No structural hazards have been found so far!"
"All sensor data are normal!"
Professor Zhao did not speak, but quickly walked to the side of the electronic screen where all the data could be viewed and quickly checked it.
A minute later, Professor Zhao stood up excitedly. "I announce! The test run was successful!"
"Wow!" All the operators couldn't help cheering loudly, followed by warm applause!
Although they did not achieve anything, they just produced it, but they were also very excited when they saw a new engine successfully tested.
Because no matter whether it can succeed or not, as long as we continue to study and experiment, then sooner or later it will have new results! Aren't countless researchers making these results bit by bit in this process?!
Doing scientific research is not about doing arithmetic problems. You can just follow the steps to solve them and get the answer.
Countless scientific research searches for the unknown among the known, the impossible among the possible, and explores directions that humans have not discovered yet.
"Xiao Jiang! It worked!" Jiang Yan Hai didn't seem too excited, and Professor Zhao came over and repeated it.
"I know that we have a tight schedule and a heavy task. We will directly conduct a long test run and conduct data tests on maximum thrust and other related aspects at the same time. If there are no problems, we will directly let them start producing the second or even the third unit."
"We still have life test, 150-hour long-term test, damage test and other test work to do in the future. One engine is definitely not enough." Jiang Yan Hai spoke simply.
Isn't it just about money anyway? Money is no longer an issue now. Once we have that material, it is normal to spend tens of billions on an engine. At the current progress of Jiang Yan Hai... is this called smashing?
No, it's like no money was spent! You must know that the tens of billions of dollars spent on the engine mentioned above are purely spent on the research process.
As for the finalization and manufacturing itself, this is not considered a research expense.
Professor Zhao hesitated for a moment, then 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 begin next. After a 10-second countdown, the fuel output will be adjusted to the maximum. Everyone pay attention to all data and report any abnormalities as soon as possible!"
"Yes!"
"10, 9, 8..." Professor Zhao is counting down continuously, and at the same time, the number of buttons to control the engine's fuel output is also increasing.
Fuel output is not unlimited, it has a limit, and this limit, after it is installed on a fighter jet, is when you push the throttle valve to the maximum position!
It's like pressing the accelerator to the floor in a car.
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 hotter!
"Fuel output to reach maximum, report the situation!"
"Smooth power output!"
"The body structure is stable!"
"The machine is running smoothly!"
"All sensor data are normal!"
"Report the thrust data!" Professor Zhao's tone was trembling.
"Report! The current thrust data is 177 kilonewtons!" The inspector over there who was testing the maximum thrust data also had a trembling tone.
"Great!" Professor Zhao couldn't help but wave his right hand! 177 thousand cattle! When converted, it is equivalent to a thrust of more than 18 tons!
This thrust is incredible! You have to know that it is small! Its volume is a little more than one-third smaller than the latest WS15A engine currently used on the J20!
The weight is about less than three-quarters of the WS15A engine. It weighs just over 1 ton. It can almost be said that it weighs only 1 ton! The thrust-to-weight ratio reached a terrifying 18! If you tell this number, it will probably be outrageous!
"Test its middle thrust!" Professor Zhao suppressed his excitement and said quickly.
The so-called intermediate thrust is the thrust at which the engine runs smoothly, and the maximum thrust just now, which is the afterburner thrust, is the thrust at which the engine fuel output is maximum. When placed on a fighter jet, it is commonly known as turning on afterburner.
The intermediate thrust data affects the cruise capability of the fighter jet.
Here we immediately started to adjust the fuel output power. When the fuel output was adjusted to a stable state, the intermediate thrust also came out.
"Report! Its intermediate thrust is 152 kilonewtons!" The operator over there gave a number that made everyone cheer.
152 kilonewtons is 15.5 tons of thrust. With two engines, it is a full 31 tons of thrust!
According to J20 calculation, its empty weight is 17 tons and its air combat weight is 25 tons. According to 25 tons calculation, this data is enough to allow it to cruise at supersonic speed without slowing down, not to mention that its maximum thrust reaches 18 tons.
Also, its size! volume! Its reduced size means that the J20 can have more space to enlarge the magazine and other aspects of the design.
"However, this data seems to have not reached our scheduled data." An operator couldn't help but remind him.
