Chapter 2526 The meaning of Marcel 2
But then the mb162 bomber modified by the French based on the mb160 had very good performance. After replacing the 4 1100 horsepower engines, the empty weight increased to nearly 12 tons, and the maximum landing weight was as high as 19 tons. (Because there was only one aircraft, which had been tested but was not actually in service, the maximum take-off weight was unclear.) The fastest flight speed was as high as 550 kilometers per hour! (When the author saw this data, he was shocked and thought that Wiki might have errors. As a result, after checking the 2-War Military Aircraft published by Armour, the above description of the speed of the mb162 was 550 kilometers per hour. Even though the test problems or the data were too scarce, it can be confirmed that this speed is also based on the basis of)
So, let's compare. What is the performance of the long-range patrol aircraft FW200 that the Germans also used passenger planes to change to? The air weight is actually similar to the mb162, about 13 tons. (Note, don't believe in this point. The data on the Wiki are wrong. I have a German version of the FW200 flight manual. Although I don't understand German, after reading the chart, the empty weight of 17 tons is absolutely impossible!) The maximum take-off weight is about 22.7 tons. The maximum flight speed is 450 kilometers per hour. When everyone's engine level is similar, the speed of the fw200c3 is 100 kilometers slower than the mb162! (That's right, this data is also wrong with the Wiki. I understand it very clearly in my manual!)
In terms of performance, if the mb162 can continue to develop, it will become a better aircraft than the fw200. It can even be considered as a full-time bomber.
If you do a horizontal comparison, how do you compare with the B17 and Lancaster bombers? It's hard to say. But if you analyze it roughly, the size of the two aircraft is similar. The empty weight of the B17 is 4 tons heavier than the MB162, and the maximum landing weight is 5 tons. The b17g uses a 1200 horsepower engine, and the total power of the four units is 400 horsepower. In the case of 455,000 pounds, the maximum speed is 480 kilometers per hour. It should be noted that the 455,000 pounds weighs only 20 tons, which is definitely not the weight of the b17's bombing mission!
If mb162 is willing to pay a price to reduce the speed and make improvements, it should not be a big problem to obtain load data similar to b17. In fact, if it is really in service, the weight increase of mb162 is almost inevitable, because you have to add a large number of facilities, such as various self-defense cannons and turrets, which will increase weight and increase resistance. Speed reduction is inevitable. Of course, the engine power may also be increased. After all, mb162 is just a semi-finished product in history. After improvement, specific things need to be analyzed!
As for comparison with Lancaster, unless it is replaced with a very amazing engine, you can't think about speed. After all, they use the famous Molin XX engine, which is a liquid-cooled engine, with the advantage of drag reduction, and the maximum output power is close to 1,500 horsepower! This power system is completely the top configuration before the B29-level bomber was put into service! It can fly at a speed of more than 500 kilometers at a weight of 620,000 pounds! This performance is indeed amazing! You know, this 620,000 pounds can be regarded as the weight load of the aircraft during the mission!
So what about comparing with the German He177? From paper, the data of the db610 is also good, but please, you can solve the overheating and stability problems before you talk about it. As for the subsequent improvements of the He177 equipped with 4 BMW801 engines, it is hard to say, after all, the number is very small. Moreover, the engine level is at least 2 levels higher than that of the mb162! How to compare this?!
So are there any larger mass-produced aircraft in Germany's history? Of course, there are, for example, the ju290, which is equipped with less than 70 aircraft, so it must not be equipped with mass production. The maximum take-off weight of this aircraft is as high as more than 40 tons, and is generally used as an ocean-going patrol aircraft, and no special bomber version has been created. If this aircraft is very good from the load alone, its speed is reasonable.
The only problem is that the engine requirements are relatively high, because this aircraft uses a bmw801h engine with a output of up to 1800 horsepower. The engine is relatively difficult and overall cost, so it is obviously not very suitable for use as a first-generation heavy bomber. After all, the engine with stable operation of 1800 horsepower is very difficult to deal with. In history, the Japanese cannot say that they have completely solved it in the end of the second battle!
Overall, it is a bit difficult for aircraft of the Ju290 level as a first-generation strategic bomber. After all, the 1800-horsepower engine is released late and the cost is relatively high. The time point of appearance will be relatively late, but compared with real NB bombers, such as the B29, it is far behind. Because the latter has a more mature design and a more abundant power system!
Therefore, the safest route for German strategic bombers should be to first create a bomber of similar to the B17 class, and then consider the b29 class. Aircraft such as the ju290 with a weight between b17 and b29 is a bit useless. Compared with the former, the ju290 is later, and the cost is relatively high. Compared with the latter, the performance is not enough.
Maybe some people have said that this is also inferred and compiled? There is no way. The design of the four-engine heavy aircraft in Germany in World War II is quite tragic, especially at the beginning, there are no more mature models like B17 and Lancaster that can be copied directly. The fw200 is a half-way product, and its comprehensive performance is worse than that of MB162.
Although the subsequent 4-shot version of he177 has been released, and the paper performance is good, it can be attributed to the engine's powerful miracle. The engine is already a bit difficult, and it is hard to say whether it can catch up with the development of the first-generation bomber. After all, we can't let the aircraft design and other engines be allowed? When the war comes, it is the most important to create a heavy bomber that can be mass-produced based on the existing subsystem!
Therefore, for Germany today, the safer way is to choose one of the future French mb162 and the 4-engine models of the He177 in history (the engine may not be able to be 1,800 horsepower at the beginning, and it may only be 1,500 horsepower at most, which will definitely lead to performance degradation.), as its first generation strategic bomber! Of course, if Italy is willing to participate, the p108 can also be one of the alternative options!
What? You say ju290? If the He177-level aircraft can use 1500 horsepower or even a low point engine, then the wings spread over 40 meters and the 28-meter-long Ju290 will use a low-end engine, then the performance will definitely be terrible! Using the BMW801 engine, it is only a maximum speed of 460 kilometers per hour (the specific weight conditions are not clear.), if you reduce the power, the maximum speed will probably not drop to the 300 kilometers level? This speed is slow and unacceptable.
