If the J-5 Sparrowhawk designed by Lilienthal and Daimler could be used as the main force of the German World War 1 fighters and light bombers in the future, it would bring some small surprises to the prince. Pen Fun Pavilion www.biquge.info then the K-4 bomber they brought with them completely overjoyed Ruprecht!

"How does this look a bit like the Gotha bomber of history?" The prince came to the giant plane, which was 14 meters long and 4.3 meters high. Wing spread width 22 meters. If you look at the appearance alone, it is similar to the Gotha aircraft, but if you look at the details, the technology used in this aircraft is completely ahead of its time.

First of all, from the wing point of view, the general early aircraft used the upper and lower concave aircraft wings, under the current technical conditions, such wing strength will be very low, so a large number of pillars and cables are needed to maintain strength, thus giving people a more chaotic feeling, and the K-4 bomber for the first time used the wing shape of the lower part of the wing straight and the upper protrusion, which increased the wing strength, thereby reducing the weight of the support structure, which is why this K-4 bomber gives people a simple and bright feeling, At the same time, with the addition of some metal structures, the strength of the wing of this aircraft has been greatly improved. Historically, this technology was only applied in 1912, so it is not too much to say that it is cross-generational.

And the most NB point is that after a little prompting from the traverser, Baron Lilinthal and others actually made a slit flap! This technology can greatly improve the stall elevation angle and the lift coefficient of the aircraft, which is why the K-4 bomber looks about the same size as the historical Gotha bomber with a wing, but has a theoretical maximum take-off weight of 4.5 tons. Relatively speaking, the wing area of the K-4 bomber is not too large, but it has a performance that surpasses that of Gotha, and the most important thing is to improve the wing design.

The only thing that made the prince feel a little depressed was that the engine of this aircraft had not yet landed....... Historically, Gotha bombers used 260 horsepower engines, and even the engines used by bombers in this plane did not exceed 200 horsepower, that is, although this frame was very good, the engine was still not in place. Of course, if you can get the 375 horsepower Eagle-3 engine produced by the British Rolls-Royce, then the performance will be even better.

But now this aircraft only has a 200 horsepower engine that can make do with it, so with a bomb load of 300kg, the range is only 400 kilometers, and the maximum take-off weight is also limited to about 3800kg. But even so, this is still a bomber ahead of its time.

The prince was also very pleased with the firepower layout of the new bomber, there was a spherical machine gun tower in the nose of the aircraft, this machine gun tower could be equipped with two 12.7mm machine guns or three 7.92mm machine guns, because the position was at the front, so the firing range of this machine gun was very good, and the bombardier was responsible for controlling the front machine gun, and was also responsible for throwing bombs.

Behind the bombardier is the pilot, who is responsible for piloting the aircraft. At the same time, there were two 7.92mm machine guns in the upper part of the cockpit, which were placed on the annular gun carriage to compensate for the dead spots of the front and rear machine guns. Behind the wings was a telegraph operator and rear-firing machine gun shooter, and two 7.92mm machine guns or one 12.7mm machine gun could be mounted on the annular gun mount. The machine gun has a wide firing range, allowing it to fire from the ground if necessary.

The aircraft's bomb pylons were placed slightly behind the fuselage to balance the weight of the nose, and theoretically up to 300kg of bombs could be carried in the middle of the belly. (after the engine change) and pylons on the sides of the wing, close to the fuselage, could hang bombs weighing no more than 150 kg per shot. And the two pylons on the outside could hang 50kg bombs. In order to improve the accuracy of bombing, this bomber is also equipped with the first generation of low-altitude horizontal bombing sights jointly developed by Bavaria Precision Instruments and Zeiss, which is said to have good performance, entering from a height of 200 meters, and the speed is controlled at about 100 kilometers per hour, bombing targets such as warehouses and freight yards should be pretty good.

At the same time, in order to ensure the firing effect of the spherical machine gun turret, the bombardier is equipped with a very primitive reflex sight. In principle, it is very high, but in reality, it is said that the experimental effect is not good, and although it is better than visual aiming, it seems that it is not very cost-effective considering the cost......

In general, this bomber is definitely worthy of the title of gunboat machine in World War 1, even if the bomb power is not considered, with 3 12.7mm machine guns and 2 7.92mm machine guns and a reserve of about 3,000 rounds, which is enough to dwarf other aircraft of this era. Although theoretically the amount of bombs is not too good, but if you consider the armament of machine guns, then this firepower is still amazing, not to mention the use of the first generation of horizontal bombing sighting equipment and very primitive and immature, but theoretically bombing the sky reflection sight! Add to that the fact that there is probably a tall telecom-free transmitter on an airplane, and this aircraft is just too powerful, at least technically!

In short, it needs to be summed up that the future is bright, but the road is tortuous, especially the engine problem, and the German engine ...... less than 300 horsepower at the end of World War 1 in history. And if the engine is not up to par, the aircraft design will not be good. Compared to the J-5 fighter, which can be mass-produced and can be used almost on the Eastern Front, the K-4 bomber will take a long time to perfect, so it will not be mass-produced in a short time.

"The problem of the engine should be solved as soon as possible, if Germany cannot solve it at home, we can go to the United States, and even Britain and France to find a suitable engine prototype, we can do whatever it takes, the problem of funds and personnel can be directly found to me, I hope that in six years, our fighter engine can be increased to 240 horsepower, and the bomber engine can be about 400 horsepower." The prince said.

As an old industrial power, the British and even the French still have considerable accumulation in some new industries, not to mention Rolls-Royce's existence until the 21st century, even in World War I, the French engine is stronger than the Germans. For things that he couldn't get for the time being, the prince didn't mind using some extraordinary means to get .......

"My request was simple: I wanted to get a 250 hp bomber engine in two and a half years, and then go into mass production three years later. Of course, pilots should start training as early as possible, and they can also continue to produce several aircraft for training first. If I could, I would like to have a squadron of pilots before the end of the year. In the end, the prince gave a timetable, three years later, that is, in 1909, there are probably less than three years before the start of the war, and the expansion of aviation is definitely enough.
