"Do you mean that the state has allocated you an Il-76?" Director Feng asked Wang Dazhi: "Comrade Dazhi, you should know that there are only a few Il-76s in our country, and the troops regard those Il-76s as precious as eyeballs, do you think they will allocate one for you to convert into an aero-engine high-altitude test bench?"

As for Wang Dazhi's statement that he wanted to test other engines under test on their platforms in the subsonic segment, Director Feng didn't take it seriously at all: you can get this done first.

Seeing that Director Feng didn't seem to be very opposed to this matter, Wang Dazhi breathed a sigh of relief and hurriedly said: " Director, of course, we know that the comrades of the army attach great importance to the only Il-76s in the country, and these Il-76 transport planes also bear very heavy tasks, we all know this, I mean, if the state allows, we will find a way to buy an Il-76 transport aircraft abroad to refit, but some of the testing and testing equipment of the aero-engine high-altitude test bench still need the state to help us coordinate. ”

Why did Wang Dazhi say these things to Director Feng, and was it not because the equipment on the aero-engine high-altitude test bench was very wrong, and it was all highly sensitive state key control equipment? If there was no special approval, even if Wang Dazhi bought the plane back, he would not be able to buy the testing equipment with the money.

"That's ......"

Director Feng groaned, this matter was a bit big, and he couldn't make up his mind for a while: "Comrade Dazhi, I can understand your thoughts, but you also know that there are some things involved......

"Director, we all know what you said," Wang Dazhi hurriedly said, "What we mean is that we welcome the secrecy department to send a special working team to our project, and when this engine platform is completed, we also welcome the necessary regulatory means." ”

"That's ......"

Hearing Wang Dazhi say this, Director Feng was suddenly shocked, he didn't expect that COMAC would take the initiative to propose that the state secrets department send a working group, so that there would be no problem. However, he still couldn't agree immediately, but nodded and said, "Then let's do it, you write a report and I'll take a look, and I want to be more detailed." ”

Wang Dazhi nodded busily and thanked Director Feng repeatedly.

Although Director Feng didn't agree to it, how could he agree to this kind of thing? Director Feng asked Wang Dazhi to write a report to him, and he was already naked #naked #naked to express his willingness to help. Wang Dazhi naturally understood this truth, which is why he was so excited to express his gratitude to Director Feng.

Director Feng, who was still a little curious, couldn't help but ask: "By the way, why did you choose to use the Il-76 as a platform? Isn't it okay to produce the improved Tu-204 yourself?"

"Director, that's right, the carrier aircraft used as a high-altitude test bench for aero engines is preferably a large four-engine aircraft," Director Feng didn't know about the situation, Wang Dazhi was not surprised at all, and he patiently explained to Director Feng: " For example, the United States and Russia have done this, and the advantage of using a large four-engine aircraft as a platform is that one of the engine mounting positions can be used as a fixed engine test point, so that the aircraft can also ensure that the aircraft has enough thrust, and the height above the ground is high enough to test the engine with a relatively large duct ratio.

But if it is a twin-engine aircraft like Tu-204 or our H-6, it can only find another way, compared to our H6 engine high-altitude test bench, we can only install the installation point of the test engine in the belly, because the ground clearance of the belly is limited, so there is no way to test the engine with a large bypass ratio. ”

"Understood. ”

Director Feng nodded, which can be regarded as an eye-opener: also, since it is an aerial test platform used to make an aero engine, it must be that the large platform has more advantages than the small platform, not to mention the large platform changed from a large aircraft, the first advantage is that the internal space is large, the internal space is large, and the large aircraft can naturally install more test equipment, and the large aircraft also has obvious advantages in terms of endurance, the same is the last day, the small platform intelligently flies for three or four hours, but the large platform may be able to fly for seven or eight hours, which means that you can test more items once you fly......

There are so many benefits.

While nodding his head to show that he understood, Director Feng casually asked, "Xiao Wang, do you Chairman Chen have any instructions for this test?"

Director Feng didn't feel that there was anything wrong with calling Chen Geng "Chen Dong", and Wang Dazhi was the same, hearing this, he said very naturally: "Our Chen Dong doesn't pay much attention to the specific work now, and he now regularly understands the company's situation, and then makes some strategic instructions, such as this test, generally speaking, we just need to report this matter to him in advance, and we don't need his approval...... Chen Dong said that now his identity is more sensitive, which is a good thing for everyone. ”

Director Feng nodded again and again when he heard this, and said with emotion: "Chen Dong is high-spirited." ”

Wang Dazhi also thought so, so he nodded and admired: "Our Chen Dong is indeed very thoughtful in many things, and there is no problem in all aspects...... By the way, director, I heard that the engines of some of the more powerful aircraft in our unit's batch of Il-76s already need to be overhauled?"

Huaxia has introduced a total of 14 (another version is 15, here is 14) Il-76 transport aircraft, these more than 10 Il-76 constitute the core of our army's strategic mobility capability, but because the number is extremely limited, so the use intensity of these more than 10 Il-76 is very high, in addition, after the high-level decided to transfer 4 Il-76 as our self-developed airborne early warning airborne aircraft platform, we can carry out transport missions of the Il-76 only 10.

Our country has such a large army, but the number of large jet transport aircraft is only so 10, you can imagine how busy the transportation of these 10 Il-76 is, what level of use intensity, in such a high-intensity use situation, and after using it for so many years, the engine needs to be overhauled smoothly and normally.

"That's the case," Director Feng nodded, and then asked casually......, "What's the matter?" You don't have what it takes, do you?"

"Director, that's not what I meant," Wang Dazhi said with a smile: "I mean, have we considered replacing the D-30KP-2 engine on the IL-76 transport aircraft with our COMAC's 'tay' MK1110?"
