Chapter 601: Matched with turbofan six

Originally I planned to continue to introduce the performance of this aircraft. After changing to air intake on both sides, how powerful the radar is installed on the nose. At the same time, how low the price of this fighter is, since foreign things are so boring. , Then, as the big brother of military aircraft research and development, we must help the Air Force complete its dream of equipping advanced fighter aircraft.
But now, after being so disturbed by Qin Guan, there is no idea at all. What else is going on? If we go on, I don't know what Qin Guan will look like.
In their eyes, Qin Guan was here to make trouble. At the same time, they were holding back a wave of anger. They said they would use digital telex, then let's go, what are we afraid of, can we not do what 6611 can do?
We are big brother!
The next project did not go on. After lunch, a group of people came to the 4410 factory.
As a big brother in the aviation industry, a leading enterprise, in addition to its subordinate 1112 aircraft factory, there is also a supporting engine 4410 factory.
With the lessons learned in the morning, no one will introduce you to the various technical data of Turbofan VI. As soon as a few slides are displayed, maybe Qin Guan will find faults again, so I will show you the real thing directly. It is more visually shocking.
In fact, if the J-8 had a real machine, it would be better for them to make a real machine, but it was too late and could only be introduced with a beautiful hand-painted picture. The result was too detailed, and Qin Guan pointed out the problem. Can't get off stage.
But now, when everyone walked into the factory building, they were immediately attracted by the engine in front of them. On the bench, the cylindrical engine was so conspicuous, and the exposed pipes were even more visible. Despite its ruggedness, under the light, the engine shell reflects light.
"Allow me to give you a brief introduction." At this time, the person in charge spoke.
He glanced at Qin Guan awkwardly, and then turned to the general present.
"Old acquaintances." Xiang Jing said behind him, these people, he knew them, and they gave him a watch before. That watch is still on his arm, let alone this expensive The time is accurate.
Thinking of this, Xiang Jing raised his arms and shook his wrists. The person in charge on the other side suddenly felt a guilty conscience.
Xiang Jing smiled happily.
"As you know, we started the development of the turbofan-6 in 1964. The project code was 910. We completed the program demonstration in 1965 and completed the trial production of the first prototype in 1968 and put it on the test bench. 1969 Completed the second prototype trial production this year."
"In the development of the engine, the experiment is the most important part, including the two changes, and some delays. For the rest of the time, we have been experimenting and overcoming various technical problems. Up to now, we have finally completed After 150 hours of continuous testing, it is a big step forward."
What's the use of the 150-hour test run?
Of course, it means that the engine has been running stably, which is a phased victory. After passing this persistent test, the next step is to install the engine.
What plane is installed? Now it seems that the Raptors are of course the most suitable.
"Let me introduce the data of our engine again. The afterburner thrust is 12 tons, the maximum military thrust is 7.27 tons, the vortex temperature is 1077 degrees Celsius, the full afterburner temperature is 1527 degrees Celsius, the total length of the engine is 5.6 meters, and the thrust-to-weight ratio is 5.93. "The face of the person in charge is smug: "So, compared to our current Spey engine, even if it is a modified version, it can't match ours."
"The turbofan six was originally a supporting project for the J-9 fighter. Now, the J-9 has disappeared, but the new J-9 has been developed. Therefore, it is the most suitable to rely on it to support the new J-9."
In Han's equipment sequence, only fighter models will have engine models. However, the development cycle of engines is much longer than that of fighter aircraft. Therefore, it will not be able to be matched, and the project will end.
Now they are fighting for new projects for Turbofan VI.
Foreign countries are different. Foreign countries first develop the core machine, and then add the core machine after the core machine is developed. The power of the fighter aircraft with small ducts, the power of passenger aircraft with large ducts, etc., one machine with multiple models, one core machine, can drive Many engines are developed.
"At the same time, we also learned that our materials department has developed new high-temperature-resistant turbine blades. Therefore, we can further increase the power of the engine by increasing the front temperature of the turbine."
The person in charge continued to introduce: "Therefore, we also have an improved model. The turbofan 6G has a weight reduction of more than 100 kg while the engine volume remains the same, and the afterburner thrust is increased to 13.8 tons, which is the largest military application. The thrust is increased to 8.56 tons and the thrust-to-weight ratio is 7.05."
The thrust of 12 tons is enough for the Raptors. If the thrust is increased to 13.8 tons, it will give the Raptors unparalleled mobility.
However, this is definitely a great leap forward.
If it is really improved to this index, what does it mean? It has entered the ranks of three generations of high-thrust turbofan engines. In terms of the paper data of the two indicators of maximum thrust and thrust-to-weight ratio, the performance of the three uncles and Taihang engines is at the same level.
If the turbofan six can be used after the modification, why should the turbofan ten be re-developed? You know, Turbofan VI and Turbofan X are a general division. Turbofan X has been in operation for so many years and the troops are unwilling to use it. That is already a thing in the 21st century. There are twenty years.
"If this standard can be achieved, there is no doubt that the Spey engine is behind." Suddenly, someone in the Air Force sighed.
Yes, if this is the case, then Spey should be eliminated and the turbofan six should be used to rematch.
At the scene, there was such a call. There is no way. The Air Force's desire for advanced fighters is quite urgent. It is so easy to have advanced things. How can you not use them?
Pushing everyone away, Qin Guan slowly walked to the front.
"This engine has passed the 150-hour test run?" Qin Guan asked.
"Yes, we have all the test data here." The person in charge on the side said immediately: "Mr. Qin, we have met your last request."
Qin Guan also mentioned the 150-hour test run. This data is the most important. An engine must pass this test run before it can be installed.
"So, was this engine the one that accepted the test task?" Qin Guan continued to ask.
The person in charge nodded: "Yes, this is the engine. It has been running for more than 150 hours now, so if you start it again, it may malfunction."
The life of the current engine is very short. This engine has withstood a test run of 150 hours, so its life is temporarily set at 150 hours. If you want to start it again, it may break down.
Let me talk about this first, you want to start it and then test it, there is a problem, but it is not our cause!
Qin nodded in view: "Moreover, after the test run is completed, will you wipe it clean?"
