Chapter 474: The Bombing of Tokyo (Part I)

The prototype of the H-1 "Mosquito" fighter-bomber is considered to be the first fighter-bomber on Shijie in history, this is because it is not only a very good bomber, but also the air fighting ability is also very good, you must know that there is no over-the-horizon air combat weapons in this era, the air combat ability is basically all the fighter, the "Mosquito" fighter-bomber shot down more than 600 enemy planes during World War II in history, for this total production of only a few thousand, and bombing as the main task of the model, which is a very good record.

It can be seen from this that the "Mosquito" is quite good both as a bomber and as a fighter, the key to which is the super maneuverability brought by the light body and strong power, and compared with the prototype, the H-1 is obviously "blue out of the blue", but because the cost is much more expensive than the average fighter, so Hu Weidong, who was once in charge of the work of the Air Force, specially stipulated that unless it is under special circumstances, in principle, the H-1 is not allowed to be used as a fighter, but even so, Of course, this has a lot to do with the lack of genuine fighter models that can compete with the new Japanese fighters before the J-1 was officially equipped with troops in 1940

In fact, just by looking at the performance parameters, you can know how good the H-1 is, she even flew a maximum speed of 642 km / h in a test flight, breaking the Shijie record for aircraft speed at that time, and becoming the only bomber in Shijie history to break the record of aircraft speed, and its prototype "Mosquito" did not exceed this value until two years later. But by that time, the H-1, which had been replaced with a new engine, had already begun to challenge the 700 km/h mark

Due to China's current unique exhaust gas turbocharging jishu, the H-1 has extremely excellent high-altitude performance, and its practical ceiling has reached an astonishing 12,000 meters, which is a full 1,000 meters more than the 11,000 of its prototype "Mosquito" fighter-bomber, and the practical ceiling of the B29 strategic bomber, which is famous for high-altitude bombing in history, is only a little more than 10,000 meters, which is not at the same level at all, although the B29 strategic bomber is terrible not only because it flies high

Similar to its prototype but even better, the H-1 can be described as "the size of a light bomber, the bomb load of a medium bomber." And unlike the "Mosquito", which only showed excellent performance in terms of load in tests. The H-1, which weighs less than 5 tons, is designed to have the ability to carry two tons of bombs on bombing missions (and the bomb load is reduced accordingly in long-range missions). The later H-1 twin-engine modification (the size was naturally enlarged a lot, and the dead weight increased to about 10 tons, which can be regarded as a standard medium bomber. It can carry a full 8 tons of bombs to take off and land safely, which is even more than the bomb load of many heavy bombers

The lightness of the body has such an astonishing load. It is inseparable from the extremely high structural strength of the H-1 fuselage. The help of German structural scientists has certainly contributed to this. But even more crucial is the amazing effect of epoxy resin on the surface strengthening of paulownia wood. At the beginning of the experiment, the "father of epoxy resin" (he didn't deserve this title in history, but this plane definitely deserves it.) Li Green was amazed at the ultra-high surface hardness of this new material, which is comparable to that of ordinary steel. After countless experiments, this process has been continuously improved and optimized, making the comprehensive performance of this new material more excellent, and a number of derivative varieties have been developed according to different uses such as load-bearing components and fuselage shells, so the H-1 and even the subsequent J-1 made of fuselage materials have even more advantages than aluminum alloy aircraft in terms of robustness, because the density of hardened paulownia wood is much smaller and the thickness of the aircraft shell can be increased, which is also equivalent to a thick layer of armor for the two aircraft, so that it has an amazing survival rate that even Hu Weidong did not fully predict

In addition, the epoxy resin research team led by Li Green also carried out research on improving the flammability of this kind of material, although it is impossible to change its flammable characteristics, but it still succeeds in greatly enhancing its flame resistance, unless it is burned in the fire for a long time, it is difficult to catch fire, which means that as long as it is not hit by a special incendiary bomb, the aircraft produced as a material is basically not burned, which makes its biggest weakness basically make up. After all, the aluminum alloy used in the aircraft during World War II will also burn up after being hit by an incendiary bomb, and the biggest weakness of hardened paulownia wood is only the same as aviation aluminum alloy, which is already a considerable advantage in itself.

As early as the beginning of the design of the H-1, Hu Weidong took into account the serious shortage of Chinese airports, and put forward almost strict requirements for its endurance, but relying on the extremely light fuselage and constantly updated engines, the H-1 is enough to satisfy it in this regard, and the maximum range of more than 3,000 kilometers makes it even after the bombing of Tokyo, Japan, there is enough fuel in the fuel tank to return home, and this is the biggest card that Hu Weidong has the confidence to force the Japanese authorities to make concessions

Because every day of stalemate means a huge consumption of manpower, financial and material resources, so after the first batch of 6 H-1 leaves the factory, Hu Weidong began to prepare for this ultra-long-range air raid that is unprecedented in the history of China and even Shijie, although none of the fighters in active service in the Air Force can escort the bombing mission of H-1 beyond its combat radius, but the safety of 6 H-1 does not have to worry, the pilots only need to rise to a high altitude before approaching the city, and the Japanese fighters and anti-aircraft guns in service are out of reach

It is true that the accuracy of dropping bombs at an altitude of 12,000 meters must be a mess, but these 6 bombers do not need to carry out precision bombing, as long as the pilots can ensure that each plane carries 1 ton (just in case, the initial mission reduced the carrying, and later practice proved that the fuel was completely sufficient, and the bomb load was restored to the design of 2 tons. It was not difficult to drop the incendiary bombs within the city limits of Tokyo, Japan. Although there are fewer 6 bombers, the fire prevention ability of Japanese-style buildings is extremely poor, and Japan also lacks modern fire extinguishing equipment, and once the fire spreads, the destructive power is much greater than the 6-ton bomb itself. As for choosing to drop bombs at high altitudes during the day instead of choosing to drop bombs at low altitudes at night (relatively speaking) as the United States burned Tokyo in history, the main reason was that the pilots who bombed the Japanese mainland for the first time could not find their targets, after all, this kind of special attack that targeted Japanese houses was indeed inhumane, and although China's retaliation was justified, if the comrades of the Japanese Communist Party were forced to mark the ground to guide the way, it would certainly be difficult for people to accept it emotionally, and if someone could not think of defecting, the losses would be great. Hu Weidong, who is acting more and more cautiously, is not willing to take this unnecessary risk (to be continued......
