Boss Yang has to hurry back to get his ultimate propeller fighter, and his first batch of modern replica versions of the Sixth Master has also begun to be delivered, but the quality of this batch of Sixth Masters is much stronger than the previous ones, and even if you look at it with your eyes, you can see the obvious difference.

And because Yang Feng said that it was not bad money, Shen Fei replaced him with a newly produced turbojet six engine, both in terms of materials and manufacturing process, which was much higher than the remaining old goods in the warehouse, not only did the thrust increase slightly, but also greatly extended the lifespan.

Although this is still a certain gap from the five or six thousand hours he expected, considering the strength of the domestic aero engine industry, it is not too demanding of others.

However, the radar is still very good, of course, it should be the most backward radar by current standards, but the search range of thirty kilometers can still be guaranteed, and a small display provides target indication for the cannon, so that in the future it can be used to go out and bully people specifically at night.

In order to satisfy customers, Shenfei Company also specially asked a special test pilot to give Boss Yang a flight performance, looking at the silver war eagle soaring in the sky, this product still couldn't help sighing.

This is a black hole that burns money, just the six six masters have been smashed into hundreds of millions of dollars so far, each light engine has been changed several times, plus the terrifying fuel consumption, you must know that aviation kerosene can not be produced for the time being, all rely on direct transportation back from modern times, flying tens of thousands of dollars, this cost performance is really not comparable with propeller fighters! If he gets another fifty back, he will feel a little sore now.

It's better to get your ultimate propeller fighter out, and you can use the sixth master as a strategic deterrent in the future, and then use it normally or play with propellers.

"Mr. Yang, there is no way to buy the piston aero engine of this level you want in the international market. Not to mention two thousand horsepower, even one thousand horsepower, now they are all turboprops. I heard that Yang Feng wanted to build some piston aero engines with more than 2,000 horsepower, and the engineer Shen Fei, who was in charge of receiving him, kindly reminded him.

"It wouldn't be difficult for me to find an engine factory and ask them to help me replicate the Pratt & Whitney R2800 from World War II, right?" Yang Feng asked.

"It's not easy. Although it is not an advanced thing in technology, you have to understand that our domestic factories have never had experience in producing this kind of thing, and the piston engine manufactured by the domestic aviation industry is only a few hundred horsepower at most, even if it can be manufactured for you, it will take a period of time to conduct various tests, it is really better to buy a turboprop directly, light weight and high power. The service life is not low, thousands of hours can be said to be very easy, even if it is our domestic one. The engineer said.

"What are the models of domestic engines of this level?"

"Turboprop five, there is not only one power, but they can all exceed two thousand, and now the most important model is the E type, and the maximum power has exceeded three thousand."

Then it seems that the only way to use the turboprop is to use it, and besides, he was going to get the turboprop back. It's not a big deal to advance now, but in this case, you still have to make aviation kerosene from the modern era.

Never mind. It's a big deal to buy some technology and go back to the Academy of Sciences to study it. Boss Yang thought helplessly.

It is not difficult to buy aviation kerosene production technology, especially since the six masters and turboprops are now large road goods, which is nothing more than spending a little more money.

But then there's another problem, if you use a turboprop, then the panda will definitely not be able to copy it, just think about the bucket-sized thick waist and know that it is not suitable for this thing.

"Are there any turboprop fighters?" Boss Yang continued to ask the engineer shamelessly.

"Now there's only one. Brazil's toucan attack aircraft, there are no fighters, and even in history, turboprop fighters are only in service with the British Wyvern, and the timing of the birth of this engine is too coincidental. At the height of the piston engine, and the rise of the turbojet engine, no country would be interested in using it for fighter power. The engineer said.

"Toucans seem to be slow, right?" Yang Feng frowned and said that this thing was eliminated in his heart a long time ago.

"More than 500 points per hour is enough as a trainer aircraft and a ground attack aircraft, and no one will use it for air combat anyway." The engineer said.

Boss Yang is very entangled, others don't use it for air combat, but he has to use it, so the speed similar to Zero Battle is absolutely not good, he needs a minimum speed of not less than seven hundred per hour, and he can directly take it back to the production model, if you need to redesign one, it will obviously delay a lot of time.

"If you really need a high-speed fighter with a turboprop engine, you can buy an aircraft converted from an old water-cooled propeller fighter, such as a Mustang, the Americans modified it during the Vietnam War, and sold it to the military as a PA48 enforcer attack aircraft, but it didn't get an order, but the prototype has been manufactured, and with their design, remove the redundant part of the design for ground attack, and use the turboprop five engine, it is completely possible to create a high-performance propeller fighter, Of course, this kind of aircraft is basically ineffective in the face of jets. The engineer said.

Boss Yang's eyes lit up, this is simply tailor-made for himself, if you replace the Mustang with a three-thousand-horsepower turboprop engine, let alone seven hundred, it is easy to fly to eight hundred, not to mention others, and with such a large power, it can even increase armor protection for the Mustang, so that its performance is even more terrifying.

I didn't care about anything else, first through Li Fatzi, I ordered a hundred turboprop five engines from Dong'an Company, of course, the kind of three thousand horsepower, and then went to his jewelry seller Philip, who was still very well connected in Europe and the United States, so he asked him to contact and buy the design drawings of the Mustang to change the turboprop, and if he could, he would also get the prototype.

Then there was the technical information on the purchase of aviation kerosene, the transportation of his first batch of twenty Liuye, and a hundred new spare engines, which tired him enough to choke until a month later.

Philip did have a lot of energy, and even went to an aviation museum and really got him a PA48 enforcer, but this one added a lot of weapon pylons, and the strange-looking enforcer disappointed Yang Feng, obviously he couldn't bring such a monster to the Republic of China.

"I like the original Mustang look, what does it look like?" The goods said dissatisfied.

"Yang, it's not difficult, we just need to find a few engineers in aircraft manufacturing and remove the parts you don't like." Philip said that Yang Feng is his god of wealth, and all needs must be met.

This work is really easy to solve, found a few people from South Africa, and it took him less than two days to dismantle the pile of bits and pieces, and then according to Yang Feng's requirements, all kinds of instruments and electronic devices in the cabin were removed, and from the hands of aviation enthusiasts, he bought an original Mustang D-type, and dismantled all the bits and pieces on it and replaced them with law enforcers, and even according to his requirements, six large-caliber machine guns were also installed, so a turboprop version of the Mustang was refitted.

However, at this time, Yang Feng also found a problem, his turboprop five engine seems to be slightly larger than that used in this aircraft, which is normal, after all, the level of domestic aero engines is decades behind the Americans.

"Just change the design drawing slightly, it will not affect its flight performance, in fact, after replacing this engine, the structure of this Mustang must also be strengthened, otherwise it is easy to have accidents if the speed is too fast." Said the designer he had invited.

Since this is the case, the changes to the drawings are handed over to this guy, but it is a very small change, and it was made in the next night with the assistance of the computer, and then the modified law enforcer test flight was carried out, and the result made Yang Feng so excited that he almost fainted, and the law enforcer after dismantling all the pieces and greatly reducing the weight, the fastest speed even exceeded eight hundred, and the maximum flight altitude exceeded ten thousand, which was still with the original two thousand five hundred horsepower engine, if it was replaced with three thousand, even if the weight increased slightly, this data could definitely be guaranteed.

There is such an aircraft, which can basically sweep the entire World War II, and the ultra-long combat radius after hanging the auxiliary fuel tank, close to the high speed of jet fighters, what kind of gale, Feiyan, purple lightning, even if you get the shock and lightning, you have to kneel.

Boss Yang, who was satisfied, sent a reward to send away his designers, and then took this ultimate mustang, twenty six masters, more than 5,000 tons of aviation kerosene, more than 10,000 tons of aviation aluminum, more than 1,000 tons of ethylene oxide, 40,000 tons of explosives, and 30,000 tons of miscellaneous goods, and wore them back to the Republic of China with trepidation.

It is fake not to tremble, although in order to avoid accidents, the beauty avatar closed the part containing dangerous goods, and then took out the air to inject liquid nitrogen into it to freeze all the explosives, but when he thought that he was guarding 40,000 tons of explosives, Boss Yang couldn't help but be shocked.

Of course, he is just a psychological effect, in fact, there will be no danger on the way through, after returning to the Dagukou wharf, or like last time, the whole railway line is closed, and then the plane is loaded onto the train, covered with a tarpaulin and transported directly to Nanyuan Airport, the sixth master and the supporting engine are loaded on the transport plane and transported to Sichuan by air, as for the ultimate Mustang will stay in Beiping, his purpose is to make this kind of aircraft here, naturally it can't be hidden, anyway, the appearance of the turboprop fighter is no different from the water-cooled fighter, and it won't cause too much sensation. (To be continued......)
