"Your reference is C-17?!"

Wang Dazhi was really shocked by the ambition of flying west: instead of using the more familiar Il-76 as a frame of reference, they aimed at the C-17, the new generation of the main force of the US Air Force?!

"Yes," Wang Xiaodong took over with a smile and said: "After all, we have mastered the manufacturing technology of 150-ton aircraft in Xifei, if it only rises from 150 tons to 190 tons of Il-76 (Il-76MD), the technical span is actually not large......

Wang Dazhi couldn't help but say: "But it's safer this way." ”

"It's really safe," Wang Xiaodong nodded: "But after the successful development of this aircraft, it may be the main transport equipment of our Air Force in the next 30 or even 50 years, do you think 'relatively safe' will work?"

“......”

Wang Dazhi stopped talking, he only felt a fever on his face!

Yes, the West Flying side is very thoughtful, after the successful development of this aircraft, it may have to be in service for 30 to 50 years, then at the beginning of the design, we must fully consider the situation of our newly developed equipment in 20 or even 30 years, rather than making this aircraft become a shackle to the development of equipment after twenty or thirty years, so that the equipment development unit in the development of a new equipment, first consider whether our transport aircraft can be transported.

Compared with Xifei, I am indeed a bit too conservative.

After settling down, Wang Dazhi asked Sun Changhong: "Little Sun, what are the approximate main indicators of this large transport plane that you envisioned?

"The first one is tonnage," Sun Changhong said: "The maximum take-off weight of the C-17 transport aircraft is 285 tons, and the result we consider is that the maximum take-off weight of our aircraft can reach 250 tons to 260 tons;

The second is the maximum load, the maximum load of the C-17 is 77 tons, considering that the Type 99 main battle tank already has a dead weight of 55 tons, and the future modification will be heavier, our initial idea is to set the maximum load at 65 to 68 tons......"

Wang Dazhi nodded again and again.

If the maximum load is 65 to 68 tons, it means that the aircraft can make an effective trade-off between range and load, after all, if the maximum load is used, then the range of the aircraft will be very impressive, but if there is some leeway in terms of load, then the range can be greatly increased, or, in the case of low range requirements, the cabin can be equipped with a master tank and then transport some other supplies, in short, there is a lot of flexibility...... From Sun Changhong's words, it can indeed be heard that they have put in a lot of hard work to study this matter.

Sun Changhong didn't notice that so many thoughts flashed in Wang Dazhi's heart, and he continued: "In terms of cabin size, we hope that the width and height are fully on par with the C-17, but considering that the single thrust of the RB211 engine of COMAC is more than 40 kN larger than that of the P&Whitney F117 engine on the C-17 transport aircraft, our idea is to leave sufficient design margin for the future, that is: the current cabin length can be a little shorter than that of the C-17, but in the future, our material technology, The level of craftsmanship has gone up, and the fuselage can be lengthened!"

Hearing Sun Changhong's words, Wang Dazhi's heart was shocked, and he hurriedly asked Sun Changhong: "Your ultimate goal is to make a 300-ton large transport aircraft?"

He was frightened by Sun Changhong's words: the design goal of the first phase of the West Flight is to make a large transport aircraft with a maximum take-off weight of 250 tons to 260 tons.

The 300-ton transport aircraft, the maximum take-off weight of the C-17 is only 285 tons, if it is really made into a "complete body" by the west, this is a real large-scale transportation integrating strategic transportation and combat transportation, right?

The current air transport system of the US military is a three-level transportation system of "C-5→ C141/C-17→ C-130", that is, C-5 completes the "hub-hub" strategic transportation, and then C-141 and C-17, two large transport aircraft, complete the transportation from the hub to the theater airport, and then the C-130 medium-sized transport aircraft completes the transportation from the theater airport to the front-line airport.

And this three-level system, even the wealthy US military can not bear it, so they engaged in a C-17, and will gradually retire C-141, in the future, the US military planned air transport system will become "C-5 / C-17 →C-130" two-level system, in which the role of the C-5 "Galaxy" transport aircraft should be weakened, and the role of the C-17 transport aircraft should be strengthened, so that C-17 has both strategic transport and campaign transport capabilities, and the final tactical air force will be completed by C-130.

Of course, we are also very envious of this set of US military troops, but envy is envy, and we even have only a few dozen medium-sized transport planes at the tactical level: How many Y-8s? There are only a few dozen of them, and as for the large transport planes Il-76, the number is even worse, so at this stage, we are still only coveting the Americans, but when did the West Fly already have such great ambitions? Is it really as Chairman Chen Geng said, to "cross the river by touching the United States"?

After a while, Wang Dazhi took a breath and exclaimed: "Old Wang, your ambitions to fly west are very great. ”
