The idea that had been vague before, now suddenly became clear, and Chen Geng asked Zhang Pengfei: "Zhang Gong, is it technically difficult for us to copy the A-1 attack aircraft?" ”

"It's not high," although he didn't understand what Chen Geng meant, but seeing that Chairman Chen didn't look like he was joking with himself, it seemed that he was discussing it very seriously, and Zhang Pengfei replied seriously: "It's actually very simple."

"Isn't it?" Chen Geng does not know much about aviation technology, but he has his own way of comparison: "Our country's Y-7 is imitated by the Soviet Union's An-24 transport aircraft, if I remember correctly, the An-24 transport aircraft was designed at the end of the 50s, and officially began service in the early 60s, our country officially decided to reverse the An-24 in April 66, and it was not until 84 years that the test flight was completed and the airworthiness certificate issued by the Civil Aviation Administration was obtained, and it took nearly 20 years before and after, although the technical starting point of the A-1 attack aircraft was a little earlier......

"Chen Dong, that's not the case," roughly understood that Chen Geng was using the technical difficulty of the Y-7 attack aircraft to compare the technical difficulty of the A-1 attack aircraft, Zhang Pengfei smiled and waved his hand: "Let's put it this way, the technical difficulty of the A-1 attack aircraft is much lower than that of the Y-7 transport aircraft, although the flight speed of the two is about the same, but in fact, the technical difficulty of the two is not on the same order of magnitude at all." ”

"Oh?" Chen Geng raised his eyebrows and said with an interested expression: "Come on, come on, let's sit down and talk, you can talk about it for me." ”

Zhang Pengfei knew that although Chairman Chen Geng was an expert in automobiles, he didn't understand many common sense things in aviation, and Chen Geng was interested in the A-1 attack aircraft, so he was naturally happy to see it, and nodded and said: "Nacheng, since you are interested, then I will tell you ......about it."

Sitting down at the table, Zhang Pengfei said: "The difference between the Y-7 transport aircraft and the A-1 attack aircraft, let's not talk about other places, but in terms of engine technology, the engines of these two aircraft are fundamentally two completely different things with completely different technical difficulties, if the technical difficulty of the Wright 'Hurricane' R-3350-26WA engine on the A-1 attack aircraft is to climb a mountain with an altitude of 1,000 meters, then the Y-1 - The technical difficulty of a turboprop engine on a 7 transport aircraft is simply to climb a mountain at an altitude of 5000 meters, right? ”

"That's right." Chen Geng nodded.

As a general expert in automobiles, Chen Geng certainly knows how big the technical gap between piston engines and turbo aero engines is, a very simple comparison can be known: Runhua Industry can now produce Wright 'Hurricane 9' and Wright 'Hurricane 18' series of engines, although there is a huge gap between the overall technical indicators and performance and the original, and the durability is not comparable at all, but it can be successfully ignited and operated, which is a huge progress, which is nothing more than a slow improvement in the future. However, for Runhua Industry, the technical difficulty of any turbo aero engine, whether it is turbojet, turbofan, turboshaft or turboprop, is not comparable to that of piston engines.

Zhang Pengfei continued: "Although the birth time of the A-1 attack aircraft and the birth time of the An-24 transport aircraft are only more than ten years apart, the mid-40s was an era of technological explosion in the history of world aviation. You only need to compare the ratio of their engines to the weight of the aircraft, although the empty weight of the A-1 attack aircraft is only 5.5 tons, of which the weight of the engine is more than 1.3 tons, and the maximum take-off weight is only a little more than 11 tons;

The empty weight of the An-24 is 13.3 tons, and the weight of the two engines is only a little heavier than the engine carried by the A-1 attack aircraft, but the maximum take-off weight is more than 21 tons, and the power per unit weight of the engine is dozens of times worse!

This is only the technical gap in the engine, specific to the fuselage, limited by the limitations of the times, the A-1 attack aircraft did not apply any new materials, new technologies, aviation aluminum alloy at that time is the most advanced material above, after all, the A-1 attack aircraft is a rough work coolie; But by the An-24, a variety of new materials, new technologies and new aviation design concepts have been widely used, so although the two aircraft are only more than 10 years apart in terms of birth time, the gap in technology is fundamentally on two levels.

For us, the technical difficulty of imitating the A-1 attack aircraft is certainly not small, but this 'not small' means that we can do it with all our strength, and as for the Y-7, let alone exerting the strength to eat milk, even if we smash the pot and sell iron, we can't do it. ”

Speaking of this, Zhang Pengfei sighed: "It's a pity, there is no market for this kind of slow-moving propeller aircraft, we are actually wasting money in this thing, and there is no point in it except wasting money......

Speaking of this, Zhang Pengfei was stunned for a moment, as if he understood the meaning of Chen Genghe's words, and scratched his head embarrassedly: "Chairman Chen, I know it's wrong, we won't waste the company's funds to do such meaningless things anymore......"

"Who says your work is meaningless?"

"......" Zhang Pengfei blinked, not understanding what Chen Geng meant by this, sneering? It's not like that.

"Do you think there is no room for the A-1 attack plane, a slow-moving, low-speed combat aircraft? On the contrary, I don't think so, no matter how slow this slow-moving low-speed propeller aircraft is, it is still much faster than the speed of a helicopter, right? If this kind of spiral aircraft is a live target on the battlefield, then there is no need for helicopters to develop, but this is not the case at all, helicopters are not only developing, but also developing very well......"

Looking at Chen Geng blankly, Zhang Pengfei felt that he didn't understand what Chen Geng meant: What do you want to say? Do you think that this slow-moving, low-speed propeller aircraft still has its own living space?

Boss, are you mistaken?

Looking at Zhang Pengfei's skeptical eyes, Chen Geng asked with a smile: "What do you think of Brazil's aviation technology?" ”

Although he didn't understand why the boss suddenly asked this question, Zhang Pengfei still answered honestly: "Well, it's still quite powerful." ”

"Did you know that there is a propeller trainer/fighter in Brazil called the EMP-312 'Brazilian Tucano'? What do you think of the hot selling? Chen Geng suddenly asked.

"......" Zhang Pengfei looked confused.

As a practitioner in the aviation industry, Zhang Pengfei naturally knows that there is a military aircraft with a model of EMB-312 in Brazil, which is a military intermediate training aircraft powered by a turboprop, and has a certain air combat and attack capabilities.

As for whether this aircraft is really a hot seller, Zhang Pengfei is completely unclear: as an aero engine R&D and designer, who cares about a non-threatening training aircraft thousands of miles away?

But he didn't think that Chairman Cheng Yan would amuse himself in this matter, so could it be that this aircraft is really hot?

Facing Zhang Pengfei's curious gaze, Chen Geng nodded affirmatively: "I don't know the specific number, but I know that the Brazilian Air Force has set more than 100 planes, the Egyptian government has set more than 100 planes, and it seems that Honduras has also set some of them, adding up to more than two hundred and fifty or sixty planes, I heard that the British Air Force has also set some, but I don't know the specific number."

Oh, by the way, I heard that Colombia is also interested in this low-cost aircraft and intends to use it to clean up drug dealers hiding in the rainforest......"

"......" Zhang Pengfei was completely stunned, and only hesitated for a while to say to Chen Geng: "What do you mean, counting the British Air Force, that is, there are almost 300 smaller ones?" ”

Not to mention the small 300 military intermediate trainers/fighters, even if it is a small 300 two-seat civilian primary trainer aircraft, such as the junior trainer aircraft like the Chujiao 6, it is a lot of money, okay? If you can really receive hundreds of overseas orders from Chujiao 6 at one time, it will be no problem for the boss of Chujiao 6 to kneel on the ground and call the ancestors.

Chen Geng shrugged his shoulders and didn't answer, what he said, do you think I can joke about this kind of thing?

Zhang Pengfei immediately believed it!

Maybe there is a little difference in the numbers, but there will definitely not be too many discrepancies, Zhang Pengfei's heart thumped, and his mouth was dry for a while, and he couldn't help but swallow his saliva: "The fuselage structure of the A-1 attack aircraft is not difficult, and the aviation equipment is also some old-fashioned things, there is no advanced electronic equipment, if we replace the R-3350 engine with a turboprop-5C turboprop engine of the same power, is it ...... Isn't it ......"

Chen Geng said faintly: "This shows that this market always exists, and the maximum bomb load of EMB-312 is only 1.5 tons, and there are only 3 or 5 hardpoints, A-1 is only 3 heavy hardpoints, and there are 12 light hardpoints, if you do not load auxiliary fuel tanks, I heard that the maximum bomb load can exceed 5 tons, and if you hang 3 heavy auxiliary fuel tanks, it is said that it can cruise in the air for more than 10 hours......"

Zhang Pengfei's breathing immediately became short: after some improvements, what EMB-312 can do, Runhua Industrial production A-1 can do, EMB-312 can't do or don't do well enough, Runhua Industry's A-1 can do better: "What do you mean...... It's ......"

"Since the technical difficulty is not high, there are ready-made templates here, and if it doesn't cost a lot of money, there is no harm in trying it, right?" Chen Geng grinned: "By the way, since you don't have to go on an aircraft carrier, you don't need to make folding wings, and the cost is saved, maybe you can decorate more weapons and ammunition, right?"
