Not only Lin Hongfei, but all the people around him frowned: the power system is the core problem of any aircraft, and for the designers of the aircraft, the saddest thing is that there is no suitable power system.

"Lao Cha, how much power can our nine-cylinder engine squeeze out?" Lin Hongfei frowned for a long time, and definitely thought of a way from himself first, "At most, it won't exceed 1,500, and it won't meet the army's requirement of 2 tons of load at all." ”

"If ......"

"Don't even think about it," Lin Hongfei was interrupted by Chapregin before he could say anything, "Boss, although we can reduce the shape of the power system by improving the aerodynamic shape, but in this way, this is a lot of work, and there is no tens of millions of dollars to definitely not think about it, will the army bear the extra cost?" ”

Lin Hongfei's idea of reducing the requirements for the power system by changing the aerodynamic shape immediately occurred before it came to him: Chaprekin was right, this would work in theory, but when it came to cost, it would become a big problem...... The army will never pay for the extra costs, and this batch of orders in the early stage was completed by the army, the Ministry of National Defense's armament department, and the air force for a long time, and it is said that the boss of the army and the boss of the air force slapped the table.

Only the complete use of the shape of the A-1 and a similar power system, which is the only way, to copy the engine of the A-1 attack aircraft? Lin Hongfei didn't have this idea at all, not to mention the difficulty of this, and what was even worse was that he would lose his underwear properly by doing so.

"I'll go and discuss it with my comrades in the army," Lin Hongfei took a deep breath, "Well, that's right." How much does the Turboprop-5E cost? Is it feasible to put it on? ”

Turboprop-5E is an imitation of AI-24, as the latest model of the turboprop-5 series, the first flip period has reached 3000 flight hours, which is very embarrassing, which one of the same type of engines in the world is not more than 4500 flight hours? But it can't be helped, the 3,000 flight hours of the turboprop-5E is already the best turboprop engine we have produced.

Chaprekin hesitated for a moment, but still spoke, "Lin, I want to advise you, if you change to your self-produced AI-24 engine." The previous part of the cockpit needs to be completely redesigned, which is not a small amount of work, and as for the price...... Well, I guess it shouldn't be more than 3 million. ”

"No more than 3.5 million?" Lin Hongfei was surprised and delighted.

"Ahem......" Wang Bolin coughed lightly, as the deputy director of the Republic Aviation Museum. He knows these things too well, "The price of Dong'an's turboprop-5E is 3.1 million RMB. ”

Lin Hongfei immediately twisted his head towards Xiao Shouting.

"If the cost of the engine can be reduced to 3.1 million. The part behind the engine is completely designed as an A-1 attack aircraft. 10 million is okay, but there is almost no profit. Xiao Shouting thought about it a little in his heart and said to Lin Hongfei. After a brief pause, he added, "And that's not even counting the cost of redesigning the nose part." ”

After a busy circle, it is equivalent to actually losing money? Lin Hongfei's eyes widened. This result was unacceptable to him in any case.

"Forget it, I'll talk to my comrades in the army about this issue." Lin Hongfei was a little depressed.

…………………………………………

"Minister Ding, I've come to complain to you." Lin Hong flew to the front of Ding Science and said with a bitter face.

The army of the republic is too large. Therefore, although the navy and air force units have their own commanders and relevant leading bodies, the army does not, and their leadership functions are in the hands of the three general departments and the Commission of Science, Technology and Industry for National Defense, while the army units are under the command of major military regions.

"Okay, I want to hear what you have to complain about," Ding Ke Ha smiled and stood up, "Speaking of which, I'm very unqualified as the deputy director of the armament department of the armed forces, it's been so long, and your boss Lin hasn't come to me to complain about it, so I have to wonder if I, the deputy minister, am too idle...... Say, what's the problem? ”

"We have found a suitable prototype for the low-altitude, low-speed, high-bomb patrol aircraft proposed by the comrades of the army," Lin Hongfei said, "It is the A-1 attack aircraft that the Americans used in large numbers during the Vietnam War. ”

"A-1 attack aircraft?" Ding Kexue frowned, and then his brows stretched, "Well, I remembered, that plane is really good, the skin is rough and thick, and there are many bombs with it, when I was in Vietnam, the biggest headache was this plane, the bullet of the 14.5mm anti-aircraft machine gun is almost like tickling, and the 23mm machine gun is not much of a threat, your kid has a good eye, and he actually chose this ...... Well, tell me, how are you going to complain? ”

"Engine," Lin Hongfei smiled bitterly, "We don't have such a high-power piston aero engine, and if we import it, the price will not be less than 2 million US dollars...... Whether it can be imported or not is another matter, but the turboprop engine of the Yunqi can also be replaced, but the previous structure of the cockpit must be completely redesigned and the blowing tunnel ...... This price is more than 10 million, I want to ask you, what to do about this problem? ”

"This is indeed a big trouble...... Ding Science frowned.

Lin Hongfei's problem is indeed very real, there is no suitable engine in China, and this type of engine has been discontinued abroad, if you want to produce and manufacture this aircraft, you must either imitate the engine yourself, or replace it with turboprop power, but imitate such a backward engine? It is better to directly match the turboprop, and the engine alone can reduce the weight by nearly one ton.

There is also a problem with the replacement of turboprop power: the nose needs to be redesigned! The cost is no small either.

Theoretically, Lin Hongfei can afford this expense, and it is not even impossible to sell it to the military at a loss, but doing so will break the rules.

"Yes," Lin Hongfei smiled bitterly, "The comrades of the army still have a demand for this kind of low-altitude and low-speed combat aircraft with a large bomb load that is between helicopters and jet combat aircraft, but I don't estimate that it will be very large, and there is no way to reduce the cost through mass production." ”

"So, Chairman Lin, what if we relax the restrictions on the external sales of this aircraft?" After thinking about it, Ding Keke thought of a way, "Since the Brazilians can sell so much EMB-312 for more than 2 million US dollars, your imitation of the turboprop-powered A-1 attack aircraft should also be possible, right?" I think that just because this A-1 is so much more powerful than the EMB-312, it will not be a problem to sell it for at least $3 million. ”

After seeing the most useful use of the border patrol planes handed over by the border guards, Ding Kexue became concerned about equipping the border troops with patrol planes, whether it was the so-called "patrol planes" that were more like toys than military planes produced by the Chujiao Sixth or the Guqi Provincial Industrial Manufacturing Co., Ltd., they were all temporary improvised things, and since the troops did have requirements for this kind of low-altitude and low-speed aircraft, it was not impossible to equip a small batch of equipment.

But now the question is, what should I do if the purchase price of 10 million RMB given by the army cannot be realized? Since the purchase price cannot be raised, there is only one way: to achieve a balance between the two sides through the price increase of export products, and if it can really achieve the level of export sales of more than 100 aircraft, maybe the second AVIC group can make a small profit.

"Export?" Hearing this, Lin Hongfei was really shocked, and said with a bitter face, "Minister Ding, the EMB-312 is a medium-sized trainer/attack aircraft, one of the countries that bought the EMB-312 is poor, and the other is the idea of buying one and two tops, and the A-1 in the aviation museum is a single-seat ground attack ......."

"Then you're going to do a two-seater attack/trainer!" Ding Science waved his hand, "Let's also have one on top of two, not only can I teach, but the actual combat effect is even more effective...... I remember that the Americans even made a four-seater A-1? ”

"This ......" Lin Hongfei smiled bitterly, "Well, let's do research first to see how much demand for this aircraft is in the market." ”

He admitted that what Ding Kexue said was right, and in the past two days, Lin Hongfei had people find a lot of information about the A-1 attack plane, and found that this plane was indeed a very good plane, not only had a basic model for ground attack, but also developed a variety of models such as night combat type, early warning type, and electronic warfare type on the basis of this aircraft, and this electronic warfare model was a four-seater. Well, there is even more outrageous, is there even a nuclear bombing type, Lin Hongfei has always been very strange, just with the maximum speed of 560 kilometers on the A-1, let this cargo drop a nuclear bomb? What the hell is going on in the head of that Pentagon bastard?

Ding Science wants to say what are you investigating, what is there to investigate? Since the Brazilians have been so successful with EMB-312 and have developed to EMB-314, there's no reason why you shouldn't succeed! But when he opened his mouth, he swallowed back when the words came to his mouth: This time Lin Hongfei helped the army so much, which has made the air force very dissatisfied, after all, he doesn't understand business, if he makes a mess for this kid, his old face will be lost.

Thinking of this, he nodded, "It's okay to investigate and investigate, Taizu once said that without investigation, there is no right to speak." (To be continued......)
