There is another important reason why Yang Feng chose the Tiger Shark, that is, he can sell freedom fighters.

Modify the air intake, change two small turbojets with a thrust-to-weight ratio of 61 levels, but no more than 2 tons of thrust, such as Rolls-Royce's Orpheus and the like, the freedom fighters will easily come out, and those small countries that are short of money still like this kind of aircraft, such as arming those little brothers around themselves, such as Assamese, Pakistan, Java and the White Army.

If you meet a master who is stupid and has a lot of money, then install radar and infrared detectors and the like, and even the Tiger has come out, anyway, these three types of aircraft are basically in the same vein, but they are upgraded step by step, and he changes it to a downgrade, and there is no pressure on this business for twenty years.

As for the production authorization given to him, Ron didn't care too much, at this time the Britons were still very generous in this regard, originally in history Attlee even sold the Soviets, as long as people with brains understood that Stalin's purchase of Nien must have been used to imitate, but they still sold it. In the early fifties, the Swedes bought the Avon 200, and they sold the production license, and as a result, the Swedes not only built their own, but also modified the afterburner into RM6, not to mention that it is now one of Britain's most important allies in the Far East.

The production authorization is only, and it is sold.

Not only did he sell the production license, but he also obtained a service contract, and within two years he helped the Ming Empire to build an Ebon engine assembly and overhaul plant in Yingtian, and sent engineers to guide the Ming workers until they were able to overhaul the engine.

In fact, in Ron's view, Yang Feng's own development of carrier-based aircraft or the production of jet engines is pure blind toss. Even if he had a few Prussian engineers on his hands. It's not like you can play with these things. This has to be supported by a complete industrial system, if nothing else, does he have a wind tunnel? Is there a high-altitude test rig? Is there a superalloy production capacity? Yes......

He doesn't have anything here, he wants to develop a jet plane, and it's a fighter, and it's the top carrier-based fighter, don't talk about it, you can do it!

But Rolls-Royce doesn't need to worry about that. They just make money.

"Your Excellency, we have a lot of infrastructure that needs to be improved."

After completing the negotiations, Henkel said worriedly.

"Then buy it, if there is something that the Prussian factory can provide, then try to provide it from the Prussian factory, if Prussia does not have it, then make a separate list, and I will solve it for you, and the wind tunnel must also be built at the same time, and someone else's must be used before it is built. But our aircraft, which had to be designed according to such a layout. ”

Yang Feng said as he spread the general structure of the tiger shark on the table in front of him.

"Single shot. Although they were able to provide only three tons of engine thrust, you had to design the airframe with six tons of normal thrust and eight tons of afterburner thrust, with two side air intakes, swept wings with edge strips, a single vertical tail, and at least seven attachment points. The belly and the inner wing of the heavy-duty pylons, which can hang auxiliary fuel tanks and heavy bombs, the outside of the wings are light-load pylons, but they must also be able to bear more than 100 kilograms, and there are also two wingtip pylons, which must be had, no matter how much needs to be solved in terms of aerodynamic design, you must also design the wingtip pylons, as for the cannon, you only need one. ”

"One cannon simply does not meet the needs of the operation."

Heinkel shook his head and said, "It's embarrassing to say hello to anyone who doesn't have four cannons these days."

"You can do it with this cannon."

Yang Feng casually pointed out the window, and not far away was an air defense position, where a fixed six-tube electric Gatling was placed.

"This enlarged version of the Gatling gun, the six-barreled 20-millimeter Vulcan, if you don't feel powerful enough, you can change it to a 25-millimeter one."

Yang Feng said.

Well, Heinkel has nothing to say, he has already seen the power of this Vulcan machine gun many times, if it becomes a twenty-millimeter cannon, it will definitely be even more ferocious, in fact, the United States and the Britons have already remembered it, but Yang Feng must have a patent right, otherwise he will not sell it, so he has been dragging it out. The people of the United States are ambitiously developing the Little Sparrow and the Rattlesnake, the former is said to be almost in production, and they are not very concerned about such backward weapons as machine guns, and it will not be long before they will do such a strange thing as an all-missile fighter.

As for other weapons, naturally needless to say, bombs and missiles are all necessary, otherwise Yang Feng would not need seven external points, anyway, with his relationship with the United States, whether it is a sparrow or a rattlesnake, it is not difficult to buy.

Of course, Henkel didn't know that Yang Feng was not ready to buy that garbage at all.

"In addition, here are some performance data of new alloys, when you design this aircraft, in the main structure, you can use a small amount of these alloys, which includes their scope of application, but the amount of use is as controlled as possible, these alloys are very expensive."

Yang Feng then took out a large book and said.

"What alloy is this?"

Henkel looked at the data on Alloy One in shock.

"Secret, and these materials can also be used in engines."

Yang Feng shrugged and said.

No. 1 is a titanium alloy, the kind developed by the people of the United States in the fifth and fourth years, Yang Feng is already preparing for small-scale production here, and even the factory has been built on a small island near Ambuna Island.

Around this archipelago, there are a bunch of various small islands, which are basically set up by Yang Feng as a forbidden area, under the heavy guard, by a large number of his personal cronies, leading those prisoners of war to be responsible for the production of secret factories, including his napalm qi oil bombs are also produced on one of the islands. In addition to the titanium alloy factory, there are more than a dozen factories of various kinds, including the pesticide factory and the circuit board factory for tape recorders, and he earns hundreds of millions of dollars a year from these factories, and he will need a composite material factory in the future.

"In addition, when you design this aircraft, you have to make sure that its body can adapt to 1.5 times the speed of sound."

Yang Feng continued.

"One and a half times the speed of sound?"

Heinkel was taken aback by him, until now the speed of supersonic speed has only been achieved in special tests, and the Führer actually wants to build a fighter with a speed of five times the speed of sound?

"But we don't have data at these speeds, and we probably don't have wind tunnels in other countries that can be tested."

Then he said.

"You don't have to worry about this, I will provide you with a part of it, and I will also provide you with a supersonic verification machine, you can get the test data yourself, don't look at me with this kind of eyes, it's just a high-speed verification machine, our family has already done it, of course, you have to keep these things secret from me, including flight tests, I will also build a test ground for you."

However, it is difficult for fighters to do any maneuvering when they fly so fast, so this ability must be had, but it is not essential, you still have to focus on medium and low altitude combat capabilities in the design, and one and a half times the speed of sound is not the most critical indicator. ”

Yang Feng said.

"Your Excellency, thank you very much for the trust you have placed in us."

Heinkel said with some emotion, of course he knows very well what this kind of data means, and the value of such a verification machine is also immeasurable, it can be said that Yang Feng unreservedly disclosed his secret technology to them, and this trust is indeed touching.

"There is no doubt about employing people, no suspicion is needed, since I asked you to be in charge of this project, I naturally have to believe you, if you think that this trust is worth anything in return, then design this fighter well, and at the same time bring out those young people under you, and when this fighter is really put into production, our Ming fighter designers can also meet my expectations for them, then I will send you back to Prussia, and build an aircraft manufacturing company there to be managed by you."

Yang Feng said.

"Your Excellency, we are forbidden to build any aircraft."

Henkel said with some bitterness.

"The world will change, believe me, it won't be long before you regain the former Prussian Confederation, you will become the strongest in the European economy again, you will have your own army, you will have an army, a navy, and even an air force, you will have everything again, and all you need is to wait quietly."

Yang Feng patted him on the shoulder and said meaningfully.

M1 is not a big deal, the mystery of supersonic speed is only to break the sound barrier, as long as the sound barrier is broken, there is a vast and smooth road behind, his fighter is now starting to develop, and it will take at least five or three years to officially put into production, because everything needs to start from scratch, maybe the time will drag on longer, at that time the MiG-21 is about to enter service, and the ghosts have begun to develop, a light carrier-based aircraft, at most, it is surprising, not to be frightened.

Then the jet fighter developed by leaps and bounds, enough to hide his glare.

As for this verification aircraft, this is not worth mentioning, just drag a J-6 from Hyundai casually.

"So what do you want for the combat radius of this fighter?"

With a vision for the future, Henkel asked.

"The maximum combat radius should not be less than 600 kilometers, preferably more than 700 kilometers, and it should not be less than 400 kilometers when taking off at full load to carry out ground or sea attack missions."

Yang Feng thought about it and said that his carrier-based aircraft was ready to be used until the late sixties and early seventies, and such a combat radius was sufficient, and he was such a small aircraft with a maximum take-off weight of more than ten tons, and it was impossible to fly out of a combat radius of thousands of kilometers.

"It has to be a folding wing!"

Then he added a word of nonsense. (To be continued......)
