Chapter 1219 (1/2)

After coming to this world, Chirac used the knowledge in his brain as a golden finger to make the rapid development of German science and technology. Under the leadership of Chirac, German military science and technology is ahead of this era.

In the cutting-edge fields, rockets, atomic bombs, long-range bombers and Germany have begun to make steady progress. In conventional weapons, tanks, fighters and artillery avoid all kinds of detours and directly manufacture the most suitable ones.

However, shirek cannot cover everything. The whole world War II expanded and involved too many aspects.

Chirac pays attention to the development of fighter planes, such as fw190 with air-cooled engine and jet aircraft, which have appeared earlier than history. However, Chirac ignores another aircraft that is not very common in this era, that is, helicopter.

Speaking of the originator of the helicopter, there will be a lot of debate. The earliest saying is Leonardo da Vinci. In his painting, the helicopter has appeared. Of course, the scientific and technological level at that time could not be realized.

It was not until recent decades that the idea of helicopters became popular again.

In 1904, Professor Zhukovsky, a Russian scientist at that time, published a paper entitled ”load capacity of rotor”, which caused great repercussions in Russia. Then the development of helicopters began to prevail in Russia, among which Sikorsky and yuryev were the most famous.

Meanwhile, in Germany, baumgarto was the first to manufacture helicopters. He began to manufacture coaxial helicopters in 1913, but this type of helicopter can not be left blank for a long time. The subsequent outbreak of World War I interrupted the development of German helicopters.

So in 1927, Flett began to study helicopters. He built a helicopter, which uses a large rotor to provide lift, is propelled by a propeller and is equipped with a 20 horsepower engine. In the test, the helicopter took off successfully, but the stability was not good. The sudden crosswind made the aircraft lose its balance, land and crash, and the test was terminated.

Without the promotion of Chirac, the development of German helicopters is almost in accordance with history.

Flett won't give up his helicopter. He's just waiting for a chance. It's 1935.

This year, the German Navy proposed to develop a helicopter that can be used on the ship. For the Navy, if they want to investigate the enemy situation, they can only rely on shipborne seaplanes. There is no big problem with ejection take-off. The main thing is landing. They want to land on the water and then be recovered by the ship's crane.

In combat, recovery will be delayed at any time. If there are planes that can take off and land vertically, it will be much more convenient for the Navy.

So, after receiving the news, Flett immediately invested and built a factory specializing in the production of Shipborne helicopters near Berlin. It was not long before he developed the fi-184 helicopter, which used a 150 HP sh14a engine and three blade with a blade diameter of 12 meters. During the test flight, he found that the performance of the aircraft was poor, so he developed the fi-185. The development of fi-185 was completed in 1936. Its appearance is similar to that of fi-184, but its performance is still not ideal.

During this period, another aviation expert in Germany also started the development of helicopters, that is, Fogg Wolff. He had a greater pomp and invited all aviation scientists in Germany, including Dr. Jack and Dr. Gast, to jointly overcome the difficulties.

A few years later, their fw-61 was also built and won the favor of the German air force.

However, up to now, their helicopters can not be said to be completely mature. They still have great technical problems, which is also the reason for the delay in finalizing the service.
