Chapter 2525 The Meaning of Marcel One

Ruprecht still admires Dassault and his company. Perhaps the aircraft produced by Dassault can only be said to be excellent, which is not as good as the top level, but it is largely due to France's own national strength and The results of economic problems, such as the production of Mirage 3 and Mirage 2K by the French, are largely due to limited economic strength and cannot be equipped with twin-engine fighter jets.

The Phantom 2K’s tragic maneuverability can largely be blamed on the engine. (Of course, the aerodynamic design is definitely not as good as the F16.) The M53 engine is completely sad to a certain extent except for its stability. As a turbofan engine, is the fuel consumption rate in the non-afterburning state higher than that of the Russian AL21? The latter is a turbojet! The only thing in the history of the engine that is described as a leaky fan is the M53.... Of course, Dassault is not responsible for the production of engines, and it is entirely possible to blame Snecma!

So, what is the value of Marcel Dassault to Germany? If it is just a propeller fighter aircraft, then this value is not so great. After all, even if it is the historical F190, if it can be equipped with a Griffin engine (the ultimate modification of the British Moline engine in World War II.) Then the performance will definitely be better. high lift. The 190D9 can be used to make do with it, and after providing an engine of nearly a grade, its performance is almost the same as that of the American and British later aircraft. So, even in the worst case, the fighters of German history can make do. So it's not a lot of pressure.

(The F190 is fine, but the BF109 is not good. The aircraft is too small, the torque is too large after the high-power engine is installed, and the wing load is too large, the handling performance is too bad. In terms of firepower, because the aircraft is inherently compact , the equipped weapons are very limited, and even can only meet the space by adding drum kits, so although it can fly very fast, the actual combat performance will be compromised.)

What Ruprecht really valued was Marcel's accomplishments in jet aircraft and transport aircraft. To be honest, although Germany has produced many bombers in history, there is no medium-sized transport aircraft that can compete with MB220. History The most famous transport aircraft in Germany is the JU52, which is equipped with three 710-horsepower engines. Its load is similar to that of the MB220, but its speed is only 265 kilometers per hour, and its cruising speed is 211 kilometers per hour. The French MB220 is equipped with two With a 915-horsepower engine, the top speed is 350 kilometers per hour, and the cruising speed is 300 kilometers per hour...

If it is fair to say, MB220 can definitely be regarded as a top-notch transport aircraft before World War II, and its performance is worse than DC2. After all, the engine power of the latter is smaller, and B220 is not as good as DC3. Because the latter uses a more powerful engine and a larger body, the DC3 uses a P1830 engine with a maximum output of 1,200 horsepower, and the empty weight and gross weight have also increased to 7650KG and 11430KG respectively. The top speed and cruising speed have also been improved somewhat. The maximum speed has been increased to 370 kilometers per hour, and the cruising speed has been increased to 333 kilometers per hour.

But from a design point of view, MB220 is on the same level as DC2 and DC3.

The performance gap between the two parties can be said to depend entirely on the engine technology. The so-called vigorously producing miracles refers to this! In other words, if Marcel is provided with two engines with a decent output, then it will have no problem making a German version of DC3!

As for the JU52? This thing is obviously a grade worse than the previous ones! The total power is actually not low, but the slow speed can be described as a snail. The difference between the maximum speed and the cruising speed is nearly 100 kilometers, what do you think? ! Of course, you can say that the JU52 came out earlier and was relatively backward in technology, but in history, Germany did not produce a better twin-engine transport aircraft.

Some people may have said, are bombers the same as medium transport aircraft? This is obviously different! Don’t think that everyone is a twin-engine aircraft. After all, the design requirements of the two sides are different. Bombers like the JU88 emphasize high speed and transport bombs, so the airframe design is like a flying pencil. And the wing load is relatively high. The requirements for the length of the runway are also relatively high.

But the transport aircraft is different. First of all, it does not require a high speed. What it requires is to transport people, so the design of the airframe cannot be made into a slender flying pencil, and it emphasizes a low wing load. Emphasis on the take-off and landing performance is not bad. For example, the wing load of MB220 is only 131KG per square meter. And the wing load of JU88G1 is as high as 240KG per square meter! The take-off and landing performance is obviously different. By the way, the wing load of Japan's Zero Type 21 fighter is 107KG per square meter.

As for, can the Germans build a good twin-engine transport aircraft? This Ruprecht can only say that there is no problem with the subsystems and that the German technology is sufficient, but whether it can be built well is another matter. After all, the performance of the Germans in transport aircraft in history is very average. And Marcel's performance is very good. In this case, for the sake of safety, before there is no better solution, Ruprecht would rather choose Marcel's MB220 improved version as a guarantee option!

Even before the war broke out, it could be used as a civil aviation aircraft in Germany. After all, the MB220 is considered one of the more mature civil aircraft in history. It cannot be used in this plane. Germany still uses the JU52...

If the twin-engine medium-sized transport aircraft is a weak point of the Luftwaffe in history, then the mature large 4-engine aircraft is another weak point. In fact, in World War II, Germany only equipped a large number of two large bombers, one is F200 and the other is HE177. The former is actually used as a hybrid of maritime patrol aircraft and bomber, the latter? Because of the brain-dead shooting requirements of the Luftwaffe, the HE177 was forced to use the DB606 and DB610 engines with complex structures and poor heat dissipation. Just a single stability is enough to make the German Air Force a headache. So do the French have anything to refer to?

First of all, let’s talk about 4-engine patrol aircraft and transport aircraft. In fact, the MB160 produced by the French and the subsequent derivative bomber MB162, which have not been put into mass production, are very good aircraft. Historically, the MB160 was developed as a 14-seat civil aircraft. If you look at the performance of the aircraft, it is actually very average. The empty weight is only 9400KG, the total weight is only 14500KG, and the maximum flight speed is only 350 kilometers per hour. Cruising speed is 310 kilometers per hour. This data is not even as good-looking as some of the last twin-engine aircraft of World War II, but you have to know that the engine used by this aircraft is only 740 horsepower! Then it is easy to understand such poor performance. After all, the engine is too watery, and you can't expect high performance!
