As for the strategic magic mentioned earlier, it is the existence of nuclear bombs, and it can be thrown at will, most of the strategic magic does not have the long-term pollution of nuclear bombs, even some strategic magic with curses can be quickly purified, strategic magic is not the so-called forbidden spell, strategic magic can be released as long as the total magic power is enough, even if you find a sufficient number of first-level magicians, it can be released, but generally speaking, the release of strategic magic is a 5~8 level magician, too high-level waste, too low-level need for the number of people that are climbed in cubic xiangshang, there are too many spell casting materials required for spellcasting, and control, command, coordination what is too difficult.

"Well...indeed...almost..."Su Fan nodded, it was precisely because of the appearance of the plane that the aircraft carrier began to replace the battleship and became a new generation of sea overlords, of course, this process has been on the earth for decades, I don't know how many years it will take to walk here, "By the way, do you know the manufacturing concept of the aircraft or something?"

"I don't know. Sten shook his head regretfully, he just imitated it stiffly according to Su Fan's design drawings, and the improvement was only to enlarge the aircraft in equal proportions and continue to create a more powerful engine, as for the fluid physics or anything, he didn't know, and Su Fan didn't plan to let him know.

"How powerful is your engine now?" Su Fan began to return to the topic, she needs an airplane, for an airplane, the most important thing is the engine, as for the aerodynamic shape Su Fan remembers in detail the aerodynamic shape of countless famous fighters on the earth, especially the propeller aircraft, he has made a lot of models, and there are materials, this problem is not a problem, this shijie's various magical materials can definitely meet or even exceed the strength required by the aircraft.

"There are about 25 magic movements, and the weight is about 600 kilograms, this kind of engine is too powerful, it can't be put on the aircraft you designed, and it disintegrates not long after takeoff, so I enlarge the fuselage and try again. Steng ushered Su Fan into the lab.

"25 Magic?" Su Fan began to convert in his heart, Magic is a power unit, because this shijie has already had a magic engine, so the power unit has also come out, the magic movement is the standard unit stipulated by the Alchemist Association, it is based on the output power of the oldest magic engine, in order to set off the author's noble and glamorous ability to name it, a magic motion is almost equivalent to 100 horsepower.

25 magic is 2500 horsepower, and the weight is only 600 kilograms, after learning about this situation, Su Fan immediately became ecstatic, the engine of this data is an artifact! You must know that the engine of the ace fighter Hell Meow during World War II is only 2100 horsepower, the first problem of the plane is solved, and the remaining two are still problems?

"Great! You're helping me get a few planes, I'll give you the blueprints!" Su Fan gave Steng a suffocating hug, and Sten's face suddenly turned red and purple - of course, this is not the reason for a certain innocent little boy, it was already said earlier that it was a suffocating hug, and Su Fan's arms hugged a man and killed even Lu Bu couldn't withstand it, let alone Sten.

"I'm going to die!" Steng quickly struggled out of Su Fan's arms, gasping for air there.

"That...hahaha..."Su Fan smiled a little awkwardly, "Do you have any paper here?" I'll draw a design for you. ”

Painting is not a problem for Su Fan, the printer on her body is not an ornament, she is a battleship, the things in her memory can be converted into information stored on the hard disk, of course the printer can print out the information inside, but this design is definitely different from the original aircraft, after all, she has only made a model, although the propeller aircraft model is similar to the principle of the real thing, but the internal structure is 108,000 miles away.

Of course, this can only be solved by Sten, the first is the control system, the control of the monoplane is a little more complicated than the biplane, Su Fan wrote the specific design on it, let Sten understand it himself; the second is the weapon system, the weapon of the aircraft is installed on the wing, the internal bomb supply system or something Su Fan does not know, can only rely on Steng to solve, this two problems must be solved, then Olive V's armament can be restored to the normal level.

"So many blueprints?" Sten watched as Su Fan kept placing stacks of paper in front of him.

"That's all, what I need is an aircraft capable of fighting, not the vase that I used to have. Su Fan put a design drawing on the table, the aerodynamic shape of the plane she can only say that it is a copycat, after all, the plane is not a tank, the one who sees five wheels is the T54, some details of the aircraft affect its performance, it is a pity that there is no wind tunnel now, so the general shape can only be made out first, and then slowly improved according to the future battle.

As for the type of aircraft that Su Fan chose? Needless to say, of course, it is the most haode! The jishu required for the propeller plane has been absolutely mature in this shijie, and the only thing missing is theoretical support, the flying objects on this shijie still rely on the magic array and the propeller xiangxia to blow the air, and the relatively advanced physical knowledge of aerodynamics is still washed and slept...

"Linna, can this thing fly?" asked Sten more than once, he could only imitate it bluntly and not understand it fundamentally, which made him very uncomfortable.

"Didn't I say it? The principle of this thing is confidential, if you want to know...give you this, just sign a contract. Su Fan took out a ring, this ring is for Olive, put Steng under the skirt...but she has been under her for a long time, Sten's alchemy can be said to be very rebellious after this period of observation, what is lacking is theory and practice, after some time of hard work, he will definitely be able to become a top alchemist, but it is strange that he did not accept any Shili's solicitation, but he is not short of money.

"...forget it..."Sten shook his head, he still can't accept becoming Su Fan's slave, Su Fan's ring needs people to be willing from the bottom of their hearts, if they are unwilling in their hearts, it is impossible to succeed.

"By the way, after you make the plane, destroy it immediately, and you must not show it to others, you can't reveal any news, you know, don't you? Otherwise, even if I don't make trouble for you, there are people who are looking for trouble for you, and when the time comes, don't blame me if someone is looking for you to talk and laugh!" Su Fan pulled Sten aside, and warned in a low voice, the plane is the main force in her fleet in the future, she doesn't want to leak it, if it weren't for her own ability to go home, she didn't want to entrust Sten at all.

"Okay..."Sten looked at the drawings in front of him, then at Su Fan, and finally the curiosity in his heart overcame the fear of trouble, and nodded in agreement.

The fighter chosen by Su Fan is the Mustang fighter that Sister Shake because of Ah Mei, although the "Mustang" is named after the Great Yin Empire, but it is produced by Ah Mei You See, in fact, P51 is not Su Fan's favorite choice, this kind of aircraft is not as good as Hell Meow in low-altitude fighting...Even zero eggs can't be beaten, the only advantage is multi-functional, and the other advantage of high range is exposed in front of the magic crystal engine, P51 can fight in the air, can dive and drop bombs, can aerial reconnaissance, It can sell cute and stupid, it can make readers ignore something strange, and the operation is very simple.

Now that two months have passed, there are less than four months to go to the battlefield to fight hard, originally Su Fan wanted to use several professional combat fighters and bombers, but although each aircraft has a design drawing, but some of the internal details are ultimately completed by Sten, and it also needs to be mass-produced, Oliver can be equipped with 100+ planes away, so many planes If there are several of them, four months is not enough time, so let's get a multi-functional fighter first.

P51 is not a carrier-based aircraft, but for aircraft in the propeller era, the wings of the aircraft are folded, plus a tail hook is a carrier-based aircraft, and it is also used as an accessory for mechanics, and the shortcomings of some land-based fighters can be perfectly overcome, as for the design of the aircraft Su Fan in addition to designing the memory to be folded, that is, the weapon has just been replaced, originally P51 is six machine guns, Su Fan replaced with two three-barreled Gatling-style machine guns (Gatling does not refer to m134, but refers to a turn-tube machine gun, just like a tethered gun does not only refer to 98K。 ), so that the bomb supply system is much simplified.

After repeatedly telling Steng to keep it secret, Su Fan left Steng's laboratory, but before leaving, she didn't forget to install a special camera in a hidden corner of the laboratory, P51 is not the copycat two-wing version of Fokker, according to Su Fan's calculations, if Stenn can really make a plane, this kind of plane can beat the air knight without any temper.

And the most important thing is that the airplane is an industrial product, and the advantage of industry is that it can be produced quickly, when you see that more than 200,000 planes have exploded in two years, it is not a joke, the growth cycle of the most common griffin of the air knights is ten years, and the wulong has twenty years, as for some high-level dragons, although they can fly the aircraft, but the two are not the same positioning at all! P51's positioning is completely a replacement for the conventional air knights.

If such an important thing leaks out, it will not only be Steng who will be unlucky, but Su Fan will also be unlucky, it has been demonstrated in the previous book, so Su Fan must definitely prevent the loss of the design drawings, if Steng leaks the secret, Su Fan will not be soft.
