Chapter 373 The Jet Age (Fourth update, please subscribe)

"Experts from Germany are present in all walks of life in Nanyang, and they play an extremely important role in various fields. Most of today's scientific achievements in Nanyang are directly related to these German experts."

Whether it is the analysis of intelligence agencies of major powers or external news reports, when mentioning Nanyang, most people will mention this, and even some experts will be mentioned. In addition to several Nobel Prize winners, Kurt Tank, That is, the designer of the famous FW190 fighter jet has also been mentioned frequently.

As early as 46, Kurk led his team to Nanyang. Although the equipment dismantled from Italy and France had not yet been installed, with the efforts of Kurk and others, the aviation industry had already begun. Basic preparation work, such as the establishment of research facilities such as wind tunnels, finally, after two years of hard work, a large wind tunnel was finally built - driven by a pair of counter-rotating wind turbines with a power of up to 88 megawatts, and a test section with a diameter of 8 meters, the maximum wind speed can reach Mach 1.

As Asia's first supersonic wind tunnel, it played an extremely important role immediately after its completion, the most important of which was the design of the FX-1 fighter jet.

"...the prototype of the FX-1 fighter is the Ta-183 Raven developed at the end of the war,"

In the Tank Center, a design institution named after himself, Kurk introduced the research progress to the visiting Air Force Commander Lukwu. Last year, the design center received a research request from the military to develop a jet fighter.

Tank is very familiar with the design of jet fighters. Starting from the end of 1944, he and his colleagues at the Focke-Wulff Design Bureau began to develop a second-generation jet aircraft for the Nazi Luftwaffe - the Ta-183 Raven. Although the Ta-183 failed to create a prototype, the finalized data was all in Tank's mind. All Tank had to do was to restore the data with his colleagues and build the prototype as usual.

This is almost equivalent to the continuation of the Ta-1945 development work that they were forced to interrupt in 183. Because Nanyang Aviation Industry has invested in Rolls-Royce's Neen engine project, Kurk used the Neen-II centrifugal jet engine provided by the British Rolls-Royce Company to replace the HeS-011A. The Nien turbojet engine has a greater power output than the HeS-011A, but uses a centrifuge instead of an axial compressor, so it is larger and longer, requiring a completely new airframe to accommodate it. This determines their working procedure - designing the fuselage around the engine, and then designing the entire aircraft with the fuselage as the core.

The result is... basically a redesign.

But it cannot be said completely. After all, there is the early design of Ta-183 as a basic template. Therefore, in theory, it is still a further development of Ta-183. Thanks to the early design based on Ta-183, They quickly completed a preliminary design, which was further refined through extensive wind tunnel testing using wooden models.

"...The wing is a thin airfoil upper monoplane with a sweep angle of 40°. It also adopts a thin wing design. This is the research result of the German aviation industry during the war. We found that reducing the airfoil thickness not only reduces drag, but also reduces airfoil thickness. It can also delay the appearance of shock waves. Shock waves have an important impact on transonic and supersonic flight..."

When Kurk introduced the wing design of the FX1, he did not know that after the war, the United States, Russia and other countries only introduced swept wing technology instead of thin airfoil design when developing their first-generation jet fighters. Later, it had to go back to achieve higher flight speeds.

Thanks to the Malthorpe design team brought by Kurk, the development of the FX1 fighter has been at the forefront of the world from the beginning. This is just a detail, but it is also a good start.

Lukwu, who was a pilot, looked at the full-size model in front of him, observed it carefully for a while, thought for a moment, and then said.

"Although I am a bomber pilot, I have also flown fighter jets. Theoretically speaking, the upper monoplane is better than the lower monoplane. In fact, the layout will have a serious impact on the pilot's downward field of vision. Therefore, can we use the wing Have modifications been made? After all, in air combat, line of sight is very important."

His suggestion made Kurk frown slightly. In fact, the Ta-183 originally used a mid-monoplane. After many blowing tests, it was changed to a high-monoplane. Now the air force commander proposed the impact of the high-monoplane. sight.

Although I am a little dissatisfied with the general's intervention, Party A's father has always been Party A's father since ancient times. This has been true at all times and in all countries. Moreover, whether the FX1 fighter jet can be mass-produced in the future mainly depends on the support of the Air Force. , and the development of aircraft itself requires a lot of funds.

So, after thinking for a moment, Kurk said.

"This requires further research, general. We are currently manufacturing the No. 1 prototype. If the test pilot reacts in this regard during the test flight, then we will make further modifications. After all, it is still in the design stage."

Kirk's answer made Lukwu laugh. "I'm just making some personal suggestions. You are still responsible for the design of the aircraft, but the military's requirements are very simple, which is jet type, good maneuverability, and long range. Of course, the specific design is completed by you. The military only cares about the specific parameters. .”

Although Lukwu was full of expectations for jet fighters, he did not supervise the progress. After all, it was the first time for everyone to fly jets, so it was better to make steady progress. Besides, now Nien The authorized production of engines has just begun, and the first batch of domestic engines will not be delivered until the end of next year according to schedule.

The Air Force is not anxious about this. After all, propeller aircraft are still used all over the world. The performance of the Air Force's FW190 and P51D is still very good. With more than aircraft, it can bully the surrounding small countries. No problem at all.

In fact, let alone a small country, even if it encounters a big country, it can give it a try. And judging from the current situation, the Nanyang Air Force is definitely the most powerful air force in Asia.

At the end of the inspection, Kurk couldn't help but ask.

"General, there is a question that we are all concerned about. The newspaper said that the Air Force will participate in the Berlin Airlift and deliver supplies to Berlin. How many planes will we send there? What kind of planes will we send?"

"Giant and Super Giant, they are our best transport aircraft with large load capacity. The Giant transport aircraft can transport 18 tons of supplies at a time, and the Super Giant can transport 35 tons at a time. In addition to leaving the necessary few, we will send all Giants."

The "giant" Lukwu refers to is the Me323 transport aircraft. This transport aircraft was Germany's largest transport aircraft during World War II. When it acquired France's Southwest Airlines, there were 1820 nearly completed aircraft in its factory. Because there were no engines, they were replaced with The American R58.1 engine has been adopted. Due to the increase in power, the performance has been amazingly improved. The maximum take-off weight has increased to 18.3 tons, and the maximum carrying capacity has reached tons.

Because the structure is simple and easy to manufacture, the Air Force is equipped with 78 "Giant" transport aircraft, and the "Super Giant" is the Me323 transport aircraft. During the war, Zeppelin Company cooperated with French Southwest Airlines to develop the model, which was completed before the German army was defeated in France. The basic design has been further improved in Nanyang Aviation Industry. It uses 6 R2200 engines with a power of 2800 horsepower, a wingspan of 70 meters, a length of 40.25 meters, and a load capacity of an astonishing 35 tons. As the world's largest transport aircraft, it can definitely play an amazing role in air transportation.

As an aircraft engineer, Kurk certainly knew the powerful transport capacity of the Giant transport aircraft, so he said with words full of gratitude.

"General, I think every German will be very grateful to you. Please convey our gratitude to the soldiers of the Air Force."

Lukwu has long been accustomed to such gratitude. After all, there are many consultants, instructors and pilots from Germany in the Air Force. Their gratitude is indescribable, and some pilots even expressed their hope to participate in the operation. After all, they are all Germans, so how can they cover the mission of rescuing their compatriots?

While feeling their concern for the motherland, Lukwu could also feel the changes in those people. They truly identified with Nanyang. After announcing their participation in the airlift, a succession of German pilots were naturalized.

On the way out of Tanke Design Bureau, Lukwu couldn't help but talk to himself when he thought about the changes in the mentality of the Germans in recent times.

"Humans, after all, are emotional animals..."
