In addition, although the exhaust gas turbocharger produced by the border area is powerful, it is smaller and lighter than the historical supercharging device during World War II, which further reduces the weight of the aircraft. As a result, the H-1 Aircraft was finalized
It actually weighs less than 5 tons, which is lighter than some single-engine dive bombers...
It is precisely because of such a light weight and the high strength of structural materials that the H-1 can not only carry out horizontal bombing like the historical "Mosquito" bomber, but can also safely carry out the "Mosquito" bomber in history.
Unable to complete the large-angle dive action, use dive bombing to accurately attack enemy warships, warehouses and other larger targets, which is different from the "mosquito" in history.
Compared with the excellent maneuverability and combat capabilities of a bomber that is almost as good as a fighter jet, the H-1 is also "outperforming the old and better than the old" in these two aspects. Even the J-1 cannot guarantee the chance of winning one on one.
Of course, considering that the H-1 is almost twice as expensive as the J-1, occasional guest appearances in air combat work are fine, but if you are full-time, forget it...
What's even more rare is that because the air-cooled engine is powerful and the fuselage is lighter and stronger, although the H-1's weight is much smaller, its load capacity is actually stronger than that of the Mosquito bomber. The first type
It can carry 2 tons of bombs. This is standard configuration. If you want to challenge the record, later models of H-1 can even carry it.
8 tons of bombs can be safely lifted into the air and landed, and the largest record of the "Mosquito" bomber in history is less than 5 tons. This gap is even greater. It is more than the model with the largest bomb carrying capacity among the "Mosquito" bombers.
It's 4,000 pounds more, and it's even more frightening when you consider that it can dive bomb...
Even with the relatively weak high-altitude performance of the air-cooled engine, thanks to its ultra-light weight and ultra-powerful turbocharger, the ceiling of the first type of H-1 exceeds 10,000 meters, with a full load of ammunition and fuel and an auxiliary fuel tank.
Compared with most types of bombers and even some fighter jets during World War II, the H-1 in this situation did not suffer any disadvantages. Therefore, it can not only benefit from
It can penetrate defenses at low altitudes at high speed, and bomb targets from high altitudes that are beyond the reach of anti-aircraft firepower. Both of these attack methods are much less dangerous than dive bombing. The "Mosquito" bomber has the advantage of having a long range.
-1 has also been inherited, especially the later models, which are even more amazing. Even without an auxiliary fuel tank, the range can exceed 3,000 kilometers...
In addition, it is similar to the historical "Mosquito" bomber. The H-1's body structure is mainly made of non-metallic materials, and the reflection rate of radar waves is much lower than that of the metal shell. Therefore, it was almost impossible to be detected by radar during World War II.
The stealth bombers of this era are still inferior to the stealth bombers of later generations due to the limited speed of piston aircraft and the visual targeting of anti-aircraft guns or aircraft guns. This is naturally a huge problem that cannot be ignored.
Advantages...
It is also worth mentioning that since the design was improved by two Soviet designers, the new H-1 inevitably bears the imprint of the Soviet style. This can be seen from one detail.
The requirements for conditions are incredibly low. Basically, you just need to find a piece of flat land with not much gravel, and then use Luoyang Heavy Vehicle Factory to separate it from the original Luoyang Automobile Factory.
As soon as the giant road roller produced rolled out, a usable field airport was formed, which only took 2-3 days. Although the life of the landing gear was greatly reduced as a result, and rainy days were increasingly hated by pilots Note 1,
During the counterattack into the occupied areas, countless frontline airports that were quickly built like mushrooms after rain greatly ensured the air superiority at the forefront of the battle...
The two world-class aircraft designers had very clear ideas for improving the H-1 prototype. Even a layman like Hu Weidong could understand at a glance why Sukhoi had to significantly modify the original design of the J-1. Hu Weidong did not know until later that After gaining a deeper understanding of aircraft design, I gradually figured it out. It turned out that although the historical La-5 had the same wooden structure as the "Mosquito" fighter-bomber, there was a huge difference between the two. The British The "Mosquito" fighter-bomber is made using a method similar to plywood, using special strong glue to bond the wooden boards together, so the size can be made larger. Although the La-5 fighter is also made of wood, it is fixed with nails. and connecting wood components, but because the ductility and elasticity of wood are not as good as metal, the size cannot be increased. In fact, the size of the La-5 fighter is slightly smaller than the Japanese Zero fighter, which is also famous for its compactness in history. Some. This resulted in it not being able to install a large engine like the Zero fighter. In fact, this also showed that the Soviet engine technology was stronger than that of the Japanese at that time. "Small engine + rough workmanship" could still compete with the strongest P51 Mustang in World War II. If the Japanese fighter can compete with this level, the Zero will not decline so quickly. However, the epoxy resin-reinforced paulownia wood material used by the J-1 and H-1 is equivalent to the "wood + glue" used by the "Mosquito" fighter-bomber. "It is an enhanced version of the craftsmanship, so there is no need to design it so compactly..."
The most direct change after the engine was enlarged was the increase in power. Within just half a year, Luoyang Aircraft Manufacturing Factory, which could only produce 900-horsepower aero engines, launched a new product with 1,500 horsepower. By the end of 1939, the basic power had been increased. That is to say, excluding the influence of the supercharger and water injector, the power has increased to 1800 horsepower. There is still a certain gap compared with the newly developed Pratt & Whitney R-2800 Double Wasp air-cooled engine by the Americans. However, taking into account the advantages of the supercharger, It is not inferior, and is even slightly stronger at medium and low altitudes. If we also take into account China's advantages in high-temperature resistant alloys, the potential for upgrading and improvement is far greater. And because of the simplification of the process, the cost has dropped significantly. Fewer. It is worth mentioning that these improvements were achieved under the premise that the engine size is fixed and there will be no major changes. Sukhoi’s suggestion is of great benefit to the coordination of the design of the aircraft, engine and supercharger. , after the first model was successfully put together, we basically only tapped into the details internally, which undoubtedly greatly saved the limited scientific research power of the border area and allowed good steel to be used on the blade...
Note 1: Even after light rain, the field airport has to wait until it dries out before rolling again. If it rains heavily, the delay will be even longer, and the aircraft must hide in the hangar during this period, if there is one. Transition, but in general, this method of quickly building and repairing field airports still has more advantages than disadvantages.
