Chapter 1330： A reborn void (1/2)
Slide 1330
Biplanes are good at turning in circles because of their light load on the wings. Good performance at low altitude and low take-off speed. But because the windward area is relatively large, the speed is worse. Moreover, the strength of the biplane is also a problem because the wings are not thick.
What about monoplanes? The circle is definitely worse than the biplane, but it has higher speed and better vertical maneuverability, and is more active in combat. But it is more difficult to manufacture. Apart from anything else, simply processing the wings is more complicated than biplanes.
Prince's requirements for the J-5 fighter are very simple. When equipped with an engine of about 450 horsepower, it can fly at a speed of more than 260 kilometers per hour, and the climb must ensure a climb rate of at least 400 meters per minute. . The weapon system is the same as the K-3, the fuel capacity is guaranteed to be around 350L, the battery life is 4 hours, and the flight range is 800 kilometers. There are 5MM armor protection on the front and back of the pilot!
Taking into account the difficulty of research, the prince did not choose to use this aircraft as the main fighter, and will not even officially enter service this year. If the plan is not going well, it will be used as a technical reserve. If the plan is going well, it will be gradually replaced next year. But it is estimated that the end of the war has come, and the prince’s plan is to end this war in three years!
If it is said that the J-5 has at least 60% of the chance to emerge in the war, then the possibility of another experimental aircraft being put into the battlefield is only about 30%. While pre-researching a single-wing all-metal fighter, it is in the Prince’s Under the impetus, he began to study single-wing four-engine bombers at the same time, which was another willingness of the German Emperor to agree to accept three-engine bombers. ——It’s not that we don’t build four-round bombers. The German Empire will definitely be able to produce the best large aircraft, but because the cycle is too long, we first use a three-round bomber to top the guard. At least that's what the prince said and did the same.
Simply stacking 4 engines, or even frantic, wanting to make a big news, stacking 6 engines is actually meaningless, it is still mainly wooden structure, it is still biplane, and it is still backward structural design. What is the point? ? The cost will be very high, the stability and technological improvement will be very advanced, and the price/performance ratio will be very low. In Ruprecht's view, for the huge aviation program, the war is just a cutscene, so some forward-looking Design must begin to accumulate, you can not make it, but you have to study!
And if this thing is improved, it can be the first-generation airliner... Well, the aviation industry is estimated to be losing money, and the country has to compensate... Let's not talk about safety and speed. Simply comfort is definitely not enough. After all, there is no pressurized cabin in this era. It is normal to take out a fur coat before boarding a plane and taking out a fur coat after boarding. Of course, this is something later, not to mention it for now.
For this bomber numbered K-8, the prince put forward several requirements. First, work hard with the engine to see if you can get 600 horsepower. If the 600 horsepower DB301 can’t get it, use 500 first. Make do with the horsepower level.
Second, it must be an all-metal monoplane, and the engine layout is a normal 4-engine layout. Never engage in a heretical layout like V1500. Not only will it not be allowed now, but will definitely not be allowed in the future...
Third, the shape of the aircraft must be scientific! As for how scientific? At least don't make a balcony-like nose like the current bomber? It's best to be rounded and streamlined. Of course, all of this must be built in wind tunnel tests. The leader’s likes and dislikes cannot be used as the standard.
