readx; With these considerations, Chen Jingyun just ordered to go down, technology can be bought, but it must be bought together with airplanes, buying technology can't make a lot of money, selling hundreds of planes out is a profitable business. Pen? Interesting? Pavilion wWw. ｂiquge。 At the same time, after the Fuzhou Aircraft Factory moved to Bengbu, the Bengbu Aircraft Factory could not obtain engines because of the outbreak of war in Europe, so it put forward the requirements for imported engines and related technology patents, after all, it is not possible to build aircraft with engines.

In these years, the technology of aero engines was dominated by France, and the aero engine technology used by the British aircraft was imported from the French aero engine technology, while the Americans imported the technology of the British, so it is not an exaggeration to say that the French are the source of the development of aero engines.

During the war, everything is easy to say, in the face of the front-line planes falling one after another, the French refused to sell the patented technology of aero engines immediately thrown in front of China, after getting this valuable technical information, the aero engine department of Shanghai Power Company on the development and imitation of aero engines can be regarded as really on the formal, and even the American enterprises that jointly developed aero engines with Shanghai Power Company have benefited a lot. Experts from the aviation department of Shanghai Power Company believe that with this technical information, together with the precision manufacturing equipment and raw materials provided by the United States, the first aircraft engine imitated by Shanghai Power Company will soon be equipped on the aircraft of the Chinese Air Force.

According to the agreement between the two sides, Britain and France each placed an order for 100 D5A fighters at the Bengbu Aircraft Factory, which is as high as 2 million yuan at a unit price of 10,000 yuan, and the Bengbu Aircraft Factory has at least half of the profits, because the cost price of the D5A fighter will not exceed 3,000 yuan, and the unit price of the D5A fighter provided by the Bengbu Aircraft Factory to the Chinese Air Force and China Navy is about 5,000 yuan. And now that the war in Europe has broken out, it is not difficult to sell it for 10,000 yuan when the price of ordnance has doubled. Of course, the more important thing is that this batch of orders was not a normal commercial ordnance order in the first place, and the British and the two countries basically directly threw out two million in exchange for the technology of the machine gun fire coordinator.

As many as 200 orders, the Bengbu Aircraft Factory could not build them for a while, and according to their monthly output of up to dozens of aircraft, it was difficult to meet the order demand for 200 aircraft in a short time. However, although the order was placed, and even the money was paid in full in advance, Britain and France did not expect China to provide a large number of D5A fighters in a short period of time, so after negotiation, Britain and France directly bought some of the D5A fighters in service in the Chinese Air Force.

As soon as Britain and France bought these more than 30 fighter planes, a large number of technical experts began to study them, and then a large group of people finally found out the firing coordinator after looking at it for a long time, and then directly reported the relevant information and technical parameters to Britain and France through telegrams.

As a result, when these more than 20 D5A fighters had not even been loaded and left Shanghai, the French aircraft factory had already begun to produce fighters equipped with shooting coordinators, and even in order to be able to put them into battle as soon as possible, they directly copied the D5A fighters while designing and developing new aircraft.

The Chinese Air Force was originally going to prepare to upgrade the aircraft in service, and the technological development of the aircraft in recent years is too fast, and the current D5A fighter is still ahead, but it is estimated that it will not take a few months to lag behind, and in another two or three years, all the aircraft now equipped by the National Army will have to lag behind.

It is precisely because of the rapid upgrade speed of the aircraft that Chen Jingyun has long instructed the Air Force to carry out the research and development of the next generation of aircraft, and even to carry out the pre-research work of the next generation of aircraft, in order to develop more advanced aircraft, the Ministry of the Air Force has even invested heavily in the construction of a large wind tunnel, and signed a research and development contract with Shanghai Power Company for the development of aero engines.

It can be said that the vast majority of the Air Force's military budget is used for the research and development of various projects, including new fighters, new long-range bombers, and new reconnaissance aircraft.

The Air Force fighter project, codenamed F1, began as early as the second half of 1913, when the Air Force had just been equipped with the D5A fighter. The D5A fighter is actually a fighter modified from the D5 reconnaissance aircraft, and its surname can deal with the original and backward aircraft of the previous no problem, but with the continuous emergence of various aircraft on the European battlefield, the surname of the D5A fighter will soon become outdated, and as the successor of the D5A fighter, the fighter codenamed F1 was designed as a full-time fighter from the beginning, in order to make the F1 fighter achieve better flight surname, the Air Force even invested heavily in the construction of a large wind tunnel, Provide various test data for the development of new aircraft.

However, the F1 fighter project did not go well, first of all, the Air Force proposed that the aircraft should have excellent air combat capabilities, so it proposed to equip the aircraft with a new aviation machine gun, instead of the current aviation machine gun improved from the Madsen light machine gun. In addition to the difficulties in the development of new aviation machine guns, the progress of aero engines has also been troublesome, at first it was to prepare to import engines, and then after the outbreak of the war in Europe, the source was cut off, so it began to look for other engine sources, and these many problems have been delayed again and again, resulting in the F1 fighter project has not been officially finalized until now.

However, the Air Force still maintains great interest in the F1 fighter, and continues to invest in research and development, the problem of aviation machine guns in Nanjing Light Weapons Arsenal after more than a year of research and development, finally succeeded in developing one, but also the world's first aviation machine gun, now the world's air forces are equipped with aviation machine guns are mostly modified from other machine guns.

The fighter design department of the Air Force has determined the basic shape and parameters of the F1 aircraft after almost two years of research and development and design according to various existing technical conditions, and has built several prototypes to use the hoarded imported engines for test flights, and the results of the test flights have made the Air Force extremely satisfied.

The F1 fighter adopts a single-engine single-seat layout, and abandons the previous two-wing and adopts a medium-single wing design, and at the same time, in order to supplement the medium-single wing, the wing is not strong enough, and it is strengthened by tension line. The design of the fuselage is entirely about how to achieve air combat superiority, and after a large number of wind tunnel tests, the final shape was determined, and its climb, instantaneous disc and other surnames can be better than the D5A fighter in all aspects, while the top speed reaches 170 kilometers per hour, the maximum range is 600 kilometers, and the nose is equipped with a 7.92 mm aviation machine gun. In terms of speed and range, the F1 fighter is not much higher than the D5A fighter, but the air combat ability of the two is very different, so specific that even the F1 fighter faces the D5A fighter as the D5A fighter faces the B3 bomber.

And this is the difference between full-time fighters and part-time fighters, which is also why the French Air Force was equipped with D5A fighters with a speed of up to 160 kilometers in the early days, but in the European theater and Germany's Fokker E3 fighters with a speed of only more than 120 kilometers per hour, they are on par with each other, because after the two are entangled, the Fokker E3 fighters occupy too much advantage, and the D5A fighters can only rely on speed unilaterally, but many times it is not said that they can go if they want to. For example, when you want to go to a specific area for reconnaissance or bombing, you can't just turn around and leave, and when the Luftwaffe is equipped with the faster Fokker E4 fighter, the speed advantage of the D5A fighter is quickly offset and shot down in large numbers, but at that time, the first generation of full-time fighters designed by the French Air Force itself are also in service one after another, and it can save the situation. This is also the reason why the two hundred D5A fighters in the Anglo-French coalition were only in service on the front line for less than half a year, and then quickly retreated to the second line.

While the prototype of the F1 was undergoing intensive test flights, the development of several other aircraft in the Air Force was also underway, such as the improvement of the B3 bomber, the main improvement work was to replace the engine and increase the range. Although the speed of the improved B3 bomber has not been increased, the range has been increased to 800 kilometers, and the bomb load has been further increased to 650 kilograms.

The research and development of the new long-range bomber, which began at about the same time as the F1 fighter project, is more progressive than that of the F1 fighter because there is no great urgency, and the development and production of large aircraft are more expensive.

As far as the Air Force and the Navy are concerned, the bombing missions of the planes are not too mature, and although the Air Force has carried out many bombing missions, it is limited by factors such as the amount of bombs dropped and the flight range, and in fact, with the exception of a few specific wars, the bombing units of the Air Force play an extremely limited role in the entire domestic reunification war, and are far less important than the reconnaissance aircraft units; it can be said that the Air Force reconnaissance aircraft units of the Nationalist Army have provided the Nationalist Army with a great deal of military intelligence and have played a vital role in the process of the domestic unification war.

Compared with the two, it is understandable that the bomber force is not much valued, of course, there is a more important reason that the research and development and production of bombers are more expensive than fighter aircraft, limited by the rise in prices of various materials during World War I, the factory unit price of B3 bombers has exceeded 7,000 yuan, which is still in the case of Bengbu Aircraft Factory did not add much profit, the price is twice as expensive as the D5A fighter.

Expensive cost and limited combat effectiveness, that is, the Air Force does not have much determination to develop new bombers, anyway, for the Air Force, the current B3 bomber is enough to meet the needs of the Air Force, as for Chen Jingyun's dive bomber designed by the Air Force, the Air Force modified a D5A fighter and carried bombs to carry out a dive bomb test, the D5A bomber disintegrated on the spot during the lifting process after the dive, resulting in the death of an Air Force test pilot, so the Air Force concluded, The current aircraft structure is not strong enough to support the need for dive-drop bombs. And when Chen Jingyun proposed the trial production of metal aircraft, and even told them to use aluminum to make aircraft, the air force department began to conduct preliminary research on metal aircraft, and this preliminary research was concretely manifested in the construction of an aluminum plant, after all, only after having aluminum can we make metal aircraft, but now even the aluminum plant is still in the preliminary preparations, and it is no longer possible to achieve it in one or two years to wait for qualified metal aircraft to be built.

The dive bomber is not good, the horizontal bomber efficiency is average, and the current B3 bomber can also be used after improvement, so the Air Force has invested the main funds in the research and development of new fighters and reconnaissance aircraft.
