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

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

But soon, Director Feng felt that he guessed the plan of COMAC Group: There are now 14 Il-76s in China, and one Il-76 transport aircraft must carry 4 engines, that is 56 engines, and at least three aircraft must prepare an additional backup engine. The 14 aircraft are calculated based on 15 aircraft, that is, 5 additional backup engines are prepared, and a total of 61 engines are prepared.

If COMAC could really get this order, it would be a considerable order, but is it really just that?

However, Wang Dazhi looked solemn and said seriously: "Director, I heard that the country is preparing to order a batch of D-30KP-2 engines and overhaul of this engine from Russia to meet the needs of overhaul and backup of the Il-76 transport engine. But in fact, the overall performance of the 'tay' MK1110 engine produced by our COMAC Group is even better than the Russian D-30KP-2.

The most important thing is that when buying our engine, not only does not need to spend foreign exchange, but also does not need to look at the face of the Russians, but also achieves the autonomy of equipment. I know that every time we talk to the Russians about purchasing, the nostrils of those Russians all grow on their foreheads..."

Huh?

If Wang Dazhi's previous words only made Director Feng feel "hehe...you continue" then when Wang Dazhi took out the two killing weapons of "foreign exchange" and "equipment independence", Director Feng was calm. He pondered for a moment and asked Wang Dazhi: "How much do you know about the engine on the Il-76 transport aircraft? Can the power of your engine achieve the performance of the engine on the Il-76 transport aircraft? What are the advantages of your engine?"

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

"oh?"

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

"In terms of maximum thrust, the thrust of our COMAC Group's 'tay'MK1110 and the D-30KP-2 engine equipped on the Il-76 transport aircraft are the same, both 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 engine has a larger bypass ratio, our engine is more fuel-efficient. The take-off fuel consumption rate of the D-30P-2 engine is 0.5 kg/Da Niu* per hour, and the cruising fuel consumption rate is 0.71 kg/Da Niu* per hour. The take-off fuel consumption rate and cruising fuel consumption rate of our 'tay'MK1110 engine are 0.436 kg/Da Niu* per hour and 0.571 kg/Da Niu* per hour, which means that if we change to our engine, under the same fuel capacity, the Il-76 transport aircraft can fly further.

In addition, the thrust-weight ratio of our engine is higher. The weight of the D-30KP-2 engine is as high as 2668 kg, with a low thrust-weight ratio and a large self-weight ratio. When the thrust-reverse device is removed, it is only 4.75. If the thrust-reverse device is included, the thrust-weight ratio is only 4.04;

The thrust-weight ratio of our engine with thrust-reverse device is 5.1, while its own weight is only 2115 kg. Compared with the original Il-76 engine, each engine is 553 kg lighter. To sum it up simply, the four engines are equivalent to making the aircraft weigh 2214 kg lighter...

Director, the weight of more than 2 tons can be reduced, so how much longer can the plane fly?"

Does it have the same thrust as the engine on the Il-76 transport plane?

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

Lower fuel consumption and lighter weight, how much longer can the Il-76 fly?

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

The transport aircraft is made of fuel. Every time the sky goes into the sky, it consumes dozens of tons of fuel. How much fuel can these 14 Il-76s save in a year?

Director Feng was moved - he couldn't help but feel moved!

However, Director Feng was not without doubt. He pondered for a moment and said, "I heard that you said, your engine seems to be really good, but your engine should be civilian, right?"

As soon as he heard what Director Feng said, Wang Dazhi hurriedly said: "Director, at the beginning of the design, our 'tay'MK1110 engine was designed according to the common standards of the military and civilians, and had passed the national model acceptance and obtained a model certificate and a production license."

Their engine was actually designed according to the common standards of the military and civilians? Director Feng glanced at Wang Dazhi: "Your company is not very thoughtful."

"Hehe..." Wang Dazhi seemed a little embarrassed. He touched his head and said, "Director, don't mention that our engine has so many advantages. Just say that our engine is domestic. Not only does it require foreign exchange, but you don't have to worry about being choked. Just this, you should also consider it?"

Director Feng nodded: "What you said makes sense, but you should know that in foreign military procurement, in many cases, it is not only economic accounts, but also political accounts must be settled... Well, what do you think about it? Let me explain it clearly. From the perspective of national defense and security, your suggestions are not impossible, but it is impossible to replace the engine at once. Even if you do not mention economic losses, the guarantee of the combat effectiveness of the army is also a problem."

Wang Dazhi didn't understand what Director Feng meant? He clearly had already let go. Hearing this, he hurriedly said: "Director, this is what we think about, first change an aircraft. The main function of this aircraft is to observe the compatibility between the engine and the aircraft and the reliability of actual use, and its advantages.

If after a period of use and observation, it is confirmed that the Il-76 transport aircraft equipped with this engine does have a clear advantage over the Il-76 equipped with a Russian engine, then gradually replace the engine while ensuring that it does not affect the combat effectiveness of the army, and at the same time, the original engine will be sealed and reserved for repair. What do you think of this suggestion?"

"Ha..." Director Feng smiled: "Don't ask me about this. You should discuss it with the Air Force at the same time. If they have no objection, you can jointly write a report."

Isn't this just a change of agreement?
