Huh?" Director Feng was stunned when he heard this: "Replace the engine on the Il-76 with the engine of your COMAC?"

Before this moment, no matter what Director Feng thought, he didn't expect Wang Dazhi to have such an idea: he actually aimed at the engine of the Il-76?

But soon, Director Feng felt that he had guessed the plan of COMAC: there are now a total of 14 Il-76 aircraft in China, and an Il-76 transport aircraft will be equipped with 4 engines, that is, 56 engines, and at least three other aircraft will have to prepare an additional spare engine, and 14 aircraft will be counted according to 15, that is, an additional 5 spare engines will be prepared, a total of 61 engines.

If COMAC can really get this order, it will be a big order, but is it really just that?

Wang Dazhi, his face was solemn, and he said: "Director, I heard that the state is ready to order a batch of D-30KP-2 engines and the overhaul kit of this engine from Russia to meet the needs of the overhaul and backup of the Il-76 transport aircraft engine, but in fact, the overall performance of the 'tay' MK1110 engine produced by our COMAC Group is better than that of Lao Maozi's D-30KP-2."

The most important thing is that not only do you not need to spend foreign exchange to buy our engines, but you don't need to look at Lao Maozi's face, but to achieve the autonomy of equipment, I know, every time we talk to Lao Maozi about procurement, those old Maozi's nostrils have grown to the door of the head one by one......"

Hey?

If Wang Dazhi's words were before, it just made Director Feng feel "hehe...... If you go on", then when Wang Dazhi took out the two big killer weapons of "foreign exchange" and "equipment independence", Director Feng couldn't be calm. He pondered for a moment and asked Wang Dazhi: "How much do you know about the engine on the Il-76 transport plane? Can the power of your engine match the performance of the engine on the Il-76 transport plane? What are the advantages of your engine?"

Hearing this, Wang Dazhi was overjoyed and hurriedly said: "It can be said that with the same thrust, our engine is more advanced!"

"Oh?"

Wang Dazhi's words really aroused Director Feng's ideas and curiosity: "How do you say this?"

"In terms of maximum thrust, the thrust of the D-30KP-2 engine on the 'tay' MK1110 and the Il-76 transport aircraft is the same, both are 110 kN, but the bypass ratio of our 'tay' MK1110 engine is 3.54, which is much higher than the 2.42 of the D-30KP-2.

Because our engines have a larger bypass ratio, our engines are more fuel-efficient, with the D-30P-2 engine having a take-off fuel consumption rate of 0.5 kg/N*h and a cruising fuel consumption rate of 0.71 kg/N*, while our 'tay' MK1110 engine has a take-off fuel consumption rate of 0.436 kg/N*h and 0.571 kg/N* respectively* per hour, that is, if you switch to our engines, the Il-76 transport aircraft can fly much further with the same fuel load.

In addition, the thrust-to-weight ratio of our engine is higher, the weight of the D-30KP-2 engine is as high as 2668 kg, the thrust-to-weight ratio is low, the self-weight, in the case of removing the thrust reverser, there is only a thrust-to-weight ratio of 4.75, if you count the thrust reverser, the thrust-to-weight ratio is only 4.04;

And our engine with thrust reverser also has a thrust-to-weight ratio of 5.1, while the dead weight is only 2115 kg, compared to the original engine of the Il-76, each engine is 553 kg lighter, a simple conversion, four engines equal to the weight of the aircraft 2214 kg lighter......

Director, this weight reduction of more than 2 tons can make the plane fly more distance. ”

The same thrust as the engine on the Il-76 transport plane?

Compared to the engine on the Il-76, the engine of COMAC is not only fuel-efficient, but also lighter?

With lower fuel consumption combined with less weight, how much longer does this allow the Il-76 to fly?

On the other hand, if you fly the same distance, how much fuel can be saved by this engine of COMAC?

The transport plane is made of fuel piles, and every time it goes to the sky, it consumes dozens of tons of fuel, and how much fuel can these 14 Il-76s save in a year?

Director Feng was moved—he couldn't help it!

However, Director Feng was not without doubts in his heart, he groaned for a while, and said: "Listening to what you say, your engine seems to be really good, but your engine should be civilian, right?"

As soon as he heard the meaning of Director Feng's words, Wang Dazhi hurriedly said: "Director, at the beginning of the design, our 'tay' MK1110 engine was designed in accordance with the common standards of military and civilian use, and has passed the national model acceptance, and obtained the type certificate and production license. ”

This engine of theirs was actually designed according to the standards of military and civilian use? Director Feng glanced at Wang Dazhi: "Your company, don't you have a lot of thoughts?" ”

"Hehe......" Wang Dazhi seemed a little embarrassed, he touched his head, and said hehehe: "Director, don't mention that our engine has so many advantages, let's just say that our engine is domestic, not only does it not need foreign exchange, but also does not have to worry about being stuck in the neck, just this, it should also be considered, right?"

Director Feng nodded: "What you said is also reasonable, but you should know that in terms of foreign military procurement, many times it is not only economic accounts that must be calculated, but also political accounts...... Hmm, what do you think? Let me explain to you that from the perspective of national defense and security, your suggestion is not impossible to consider, but it is impossible to replace all the engines at once, and even if economic losses are not mentioned, the guarantee of the army's combat effectiveness is still a problem. ”

Hearing this, he hurriedly said: "Director, we think so, let's change an aircraft first, the main role of this aircraft is to observe the compatibility between the engine and the aircraft, as well as the reliability and advantages of actual use.

If, after a period of use and observation, it is determined that the Il-76 transport aircraft equipped with this engine does have obvious advantages over the Il-76 equipped with a Russian-origin engine, then gradually replace the engine without affecting the combat effectiveness of the army, and at the same time mothball and spare the original engine after repair, what do you think of this suggestion?"

"Ha......" Director Feng smiled: "You don't ask me about this, you can discuss it with the Air Force first, if they have no opinion, you can jointly write a report together." ”

Isn't this a disguised agreement?

Wang Dazhi hurriedly thanked Director Feng.
