readx; The development of the air force of the national army is extremely rapid, Chen Jingyun made up his mind after the war in southern Jiangsu, even if these wooden frame aircraft fighters are still extremely weak, and the bombers have too little bomb load, resulting in the ground bombing, only the first few times have achieved great results, and the follow-up bombing operations in the southern Jiangsu war have not achieved great results, but now the reconnaissance ability of the aircraft cannot be ignored, when the southern Jiangsu war because the national army has aerial reconnaissance, it almost led to the one-sided collapse of battlefield intelligence, so that the national army has a great intelligence advantage. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

It can be said that such an aerial reconnaissance capability has been able to influence the situation of the war.

In addition, the aircraft at this time is more difficult to design in the early stage, once the design is finalized, it will be much easier to build, the most critical component of the engine is directly imported, and then get a wooden frame to install it in, it is simpler than building an artillery, this can be from the cost of the two, the cost of building a 75 mm mountain gun in Fuzhou Arsenal is about 5,000 to 6,000, and the latest model of a D5 single-engine aircraft in Fuzhou Aircraft Factory is only 2,000 Wu Bai Yuan, On the basis of the D5, the D5A fighter, which was modified from the Madsen light machine gun and equipped with an aviation machine gun, was only 3,400 yuan, and even though the latest two-seater twin-engine B3 bomber was more expensive, it was only more than 5,000 yuan. These prices are much cheaper than artillery.

In the early days of aircraft development, the aircraft was not expensive, the only thing that was more expensive was its engine, the fuselage was wooden, and there were not many parts like those later aircraft, and the current aircraft was still in a very primitive stage, and the design and manufacture of the whole aircraft were not as difficult as the later aircraft, and it would not be said that the modern aircraft of later generations would take ten years from design to finalization, and there would not be a country, and the entire air force of a country could only be equipped with a few hundred aircraft. In this era when private workshops can design and build airplanes, airplanes are an expensive toy in someone's eyes.

In this era, the design and manufacture of the whole aircraft is not difficult, but the core components of the aircraft: the engine is not an easy task, whether the engine is modern or 1913, it belongs to those large industrial countries to be able to manufacture, the current Fuzhou aircraft factory has no ability to manufacture engines independently, and the engines used in the aircraft manufactured now are all imported, and most of them are French goods such as Renault V8 engines, etc., and a few are imported from the United Kingdom and the United States. However, the main thing is the Renault V8 series engine, the current Renault V8 series engine in the aviation industry is the world leader, and the later British Rolls-Royce and other companies still imitate the Renault V8 second, and the Soviet Union and the United States are copying Ross's Eagle engines.

In order to solve the engine problem, Chen Jingyun had already asked the Fuzhou Aircraft Factory to start the imitation work of the engine, so as not to be controlled by others in the future. However, this engine is not so easy to develop, and it is okay to let the Fuzhou Aircraft Factory cut a few pieces of wood and build an airplane, but it will be difficult for them to get the engine. This embarrassing situation is like letting Mawei Shipyard and Jiangnan Shipyard develop advanced steam turbines, it can be said that the profession is fundamentally wrong, and they also lack sufficient technical strength.

Under the slow progress of the Fuzhou Aircraft Factory's imitation of engines, Chen Jingyun had no choice but to take this important task out of the Fuzhou Aircraft Factory, and then selected technical experts from various departments of the Fuzhou Arsenal to set up an aero engine research institute and join the Shanghai Power Company, which now involves aero engines in addition to developing steam turbines for marine power. In addition to these two important research projects, the person in charge of the company in order to reverse the company's unprofitable projects, change the situation that has always needed the continuous investment of the head office Huaxia Bank, independently prepared three other research and development projects, namely industrial steam engines, high-power diesel engines and gasoline engine projects, the progress of these three projects is much smoother, Shanghai Power Company has come up with samples, among which the industrial steam engine has received a lot of orders, The Fuhang Textile Company placed an order for 10 large industrial steam engines for the expansion of the silk reeling factory project. And the development of gasoline engine has also been supported by Chen Jinghai, chief financial officer of Huaxia Bank, in view of the rise of the automobile market in China, now there are a lot of cars in Fujian, Zhejiang and Shanghai, so the investment in the establishment of a small-scale automobile factory, many parts are also imported from abroad, ready for small-scale trial production of cars, of course, these produced cars are also self-produced and sold, the national army and political axe need a large number of official cars, even if the production of the surname can be worse, it doesn't matter if it runs slower, As long as the style is good-looking, don't just drop anchor.

The development of Shanghai Power Company can be said to be related to the development of a series of military projects of the future national army, such as warships, such as airplanes, such as tanks envisioned by Chen Jingyun, and even military cars have to rely on their engines.

However, the development of Shanghai Power Company is limited to the development of the domestic basic material level, it is easy to design the engine, but you have to manufacture it, and you need those high-quality materials to meet the harsh working environment of the engine. At present, only Southeast Iron and Steel is responsible for the research and development and manufacturing of basic steel in China, but Southeast Iron and Steel has only been established for more than a year, and even heavy equipment and workshops have not been completed, and the focus of development and production is also on artillery steel, and it is still time for the research and development of other special steels.

Based on this situation, Shanghai Power Company can only import these high-quality raw materials abroad. Fortunately, in these years, no country has imposed a technological blockade on China, and you can buy whatever you want, but the price is extremely expensive.

After purchasing these expensive raw materials, Shanghai Power Company was able to carry out a series of development and production work, and the steam turbine project and aero engine project were carried out in an orderly manner.

Naturally, the Fuzhou Aircraft Factory could not wait for the Shanghai Power Company to toss slowly, and it was impossible for the domestic engine to be used in a short period of time, and the production task of the Fuzhou Aircraft Factory was very heavy, and the orders of the Equipment Department had already filled Qin Guoyong's desk.

Fuzhou Aircraft Factory currently produces two types of aircraft, one is the D5 single-seat single-engine biplane, and the other is the B3 two-seat twin-engine biplane.

The aircraft research and development process of Fuzhou Aircraft Factory began at the end of 1911, and up to now many aircraft models have been tested and manufactured, and many aircraft models were produced in the early stage, from D1, D1A, D1B to D2 series, and then to D3 series, basically only one or two or three models of a model, all of which were only used for testing, and it was not until a year later that the D4 aircraft was initially finalized, and on this basis, the reconnaissance type, fighter type, and bombing type were improved. The prototype that the National Army began to purchase was fine when it was used as a training aircraft, but the various models that were modified later, such as the D4C reconnaissance aircraft and the D4A fighter and the D4B bomber type, were not ideal, and the breakdowns were frequent, and crashes occurred from time to time during any or training, and the various types of aircraft produced have fallen by more than half so far, and the pilots have sacrificed a lot. For this reason, Wu Shizhong has asked the armament department to re-purchase a stable aircraft, and has proposed to specialize in the research and development of specialized aircraft, such as reconnaissance planes are reconnaissance planes, fighter planes are fighter planes, and bombers are bombers.

For this reason, the armament department issued a new aircraft model to the Fuzhou Aircraft Factory and stopped purchasing old models, thus forcing the Fuzhou Aircraft Factory to concentrate on developing new models of aircraft.

Fuzhou Aircraft Factory re-developed on the basis of the D4 type, improved the main structure of the fuselage, and adopted a higher power engine, further improved the flight surname at the same time, but also optimized the safety of the aircraft, put the safety surname of the Air Force in the first place, and finally designed a new model of the D5 type aircraft, the aircraft inherited the D4 single-seat single-engine double-wing structure, the horsepower increased to 110 horses, the ceiling of 3,000 kilometers, the maximum speed of 160 kilometers per hour, and the endurance reached 3.5 hours. The range can reach about 550 kilometers, and the combat radius reaches more than 200 kilometers.

After the Air Force came to test the flight, they spoke very highly, saying that this aircraft was easy to operate, the flight was smooth, and the safety was greatly improved compared with the previous D4 aircraft, and because it was easier to operate, it was easier to train pilots. At that time, more than 30 orders were placed to purchase the D5 basic type, in addition to half of the supplementary aviation school for training cadets, the remaining half was supplemented with the reconnaissance squadron of the first wing.

Not long after, the Fuzhou Aircraft Factory developed the D5A fighter model on the basis of the D5 basic model, added the Madsen aviation machine gun, and created the surname of the use of the cam shooting synchronous coordinator, relying on the rotation of the propeller to control the shooting of the machine gun, so that the aviation machine gun can be arranged to the nose position, and the pilot can fire directly by remote control, instead of the previous modified models of fighters can only be arranged on both sides, relying on the recoiler shooter for manual shooting. In this way, the air combat capability of the D5A will be greatly increased.

As for the good things, and Chen Jingyun was slightly biased in favor of the Air Force, the Air Force had sufficient funds for equipment procurement, and at once issued an order for two squadrons, which was to prepare to retire and dispose of all other fighters in active service of the Nationalist Army. The other active D4A fighters of the National Army are simply a lot of trouble, and the pilots have to write a suicide note in advance when they perform the mission, and the safety surname is too poor, and now that there are substitutes, Wu Shizhong did not hesitate to clean up all the D4 planes that killed more of his own people than the enemy.
