Rhema Horton was visibly stunned when he heard this, this was a little different from what he expected!

If Kurt Tanck's jet project was approved, why didn't he continue working on his project when he arrived?

"What do you mean by my project being too far ahead? Didn't you just say that our project gained stealth performance? ”

Fang Lang smiled and pointed to the chair behind Rhema Horton's desk, motioning for the other party to sit down and chat.

"I would say that your project is full of genius imagination, but the current scientific foundation is not complete, and it will take a process to monetize your imagination.

I've seen the product you developed, and now this product is in the American Research Institute, and the Americans are also doing research, and I have to say that it is very beautiful.

But I think you should also know very well that the flying wing structure you are pursuing has inherent defects in lateral stability, which is the inevitable result of not having a vertical tail.

And if you want to solve this problem, with the current level of science and technology, it is basically an impossible task. Otherwise, several of your prototypes would not have crashed one after the other.

As for the stealth performance you are talking about, do you know why your aircraft has such an effect?

Obviously, you don't know it yourself, and I have some guesses about it in my mind, but I don't think it's time to say it.

When the state of technology is enough to support us to restart this project, I will not hesitate to share everything I know with you without reservation.

Since this project can't be carried out right now, you can't just waste time here, can you?

I think that starting a new study from a different perspective may or may not be pleasantly surprised! ”

Fang Lang's words made Ruima Horton speechless, he was very aware of his flaws in the products he researched, as Fang Lang said, the whole aircraft because there was no vertical tail, the lateral stability was extremely poor, and even the steering was difficult, which made their prototype collapse and sink.

Now Fang Lang's meaning is not to ask them to give up completely, but to wait for the further progress of science and technology, although this is a suspicion of painting cakes, but he is also very clear in his heart.

Fangyuan Aircraft Manufacturing Company is only a private enterprise, not a state-owned institution, and it is impossible to come up with a large amount of money and unreservedly support them to spend money on research.

It is impossible for me to really do nothing, just insist on my insistence on the structure of the flying wing.

So, in the end, Rhema Horton sat down in the chair with some weakness, and the whole person was a little depressed.

Seeing this, Fang Lang didn't know how to comfort the other party, thinking of a very interesting sentence in the future, the best way to cure a broken love is to start a new relationship.

The current state of the other party seems to have the same effect. So he simply spoke:

"As you can see, one of our company's biggest businesses now is to modify military transport aircraft and deliver them to civil aviation for use as civil airliners.

It is obvious that the civil aviation market will be a huge cake in the future, and most of the passenger aircraft are still in the propeller stage.

Of course, some airlines in the United Kingdom and the United States have begun to enter the jetliner market in a big way, and major aircraft manufacturers are investing heavily in the research and development of jetliners that are faster, have a longer range, carry larger passengers, have higher safety, and are even more fuel-efficient.

As a newly established aircraft manufacturing company, if our company cannot seize this opportunity and enter this field one step ahead, then we will fall behind step by step.

The company's development will also be hindered, not to mention whether it will be able to complete my promise - to restart your research project. It is estimated that there will be big problems in the production of our company.

So, I would like to appoint you as the chief designer to develop our own jet airliner, quickly occupy the booming civil aviation market, and obtain more funding to support our follow-up research.

I don't know what you think. ”

Ruima Horton looked at Fang Lang with a surprised expression, and said in disbelief:

"You want me to lead the study of civil airliners? But I've never had any experience with that! ”

smiled and waved his hand, looked at the other party with a serious face, and said in a sincere tone:

"It doesn't matter if you don't have experience, I will make specific R&D requirements, and I will also explain to you the information on the main aircraft types of other aircraft manufacturers.

The company's resources will also be tilted towards you, and we can also start recruiting immediately. In short, your civil airliner project will be the most important project of our company in the next few years.

I hope that you can use your genius mind to develop excellent aircraft for us that can occupy a place in the civil aviation market. ”

Fang Lang's meaning is very clear, that is, to concentrate the company's strength to research new civil airliners.

Ruima Horton could also clearly feel Fang Lang's determination, which made him feel Alexander, but he was not someone who would be scared by pressure, Fang Lang's trust made him have to start taking this task seriously.

For a person like him, the pressure will not make him back down, but will only make him rise to the challenge, so he didn't think long before he got up directly, looked at Fang Lang with a solemn face, and said in a serious tone:

"Thanks to the trust of the boss, I took this task.

Rest assured! I will do my best to not let you down. ”

Seeing this, Fang Lang suddenly got up with a smile on his face, stretched out his right hand towards Rhema Horton, and held it tightly with the other party.

"Okay, then I'll go to Ante Polman and announce the start of our civil airliner project.

Before that, I would like to discuss with you the design ideas of civil airliners. ”

As he spoke, he took out a blank piece of paper directly from the other party's desk and began to teach Rhema Horton about his requirements and understanding of civil airliners.

"Civil aircraft and military aircraft have a lot in common, but there are big differences, first of all, the most important thing is definitely safety, whether it is a civil aircraft or a military aircraft, the most important thing is to ensure absolute safety and reliability.

The difference between civil airliners and military airliners is that they have special requirements for economy, and you must know that airlines do not buy airliners for charity, but to make money.

So, in addition to safety, they are most concerned about economy, and in short, they want to be able to consume the least amount of fuel and transport as many people as possible to the farthest places.

And this is an important basis for our research and development of civil aviation passenger aircraft.

This meant that we had to use the jet engine with the highest fuel economy first, and this was the first challenge we had to solve.

As far as I know, the current British Rolls-Royce company is researching an engine that installs a fan in front of the turbojet engine to achieve the purpose of increasing the frontal area and increasing the air flow.

According to the latest intelligence, the ground take-off thrust of this engine has increased by about 40 percent, while the fuel consumption during high-altitude cruising has decreased by 15 percent, and the efficiency of the engine has been greatly improved.

I heard that as early as 1943, Mercedes-Benz had begun to develop a turbofan engine codenamed DB670. Unfortunately, at that time, they installed the position of the fan behind the turbojet engine, and the experiment was not successful.

Is that so? ”

As a German aircraft designer, Rhema Horton is obviously very familiar with the situation of German aircraft engines, and after hearing Fang Lang's question, he also nodded slightly disappointed and said:

"Yes, I have also heard about this research project, but unfortunately it was not successful."

Hearing this, Fang Lang patted the other party's arm with a smile and said:

"It's okay, now we still have a chance to catch up, you can see if you can use your network to get the engineers of this project together again.

Combined with the successful experience of the British, restart the study of our own turbofan engines. ”

In fact, Fang Lang panicked here, that is, the current British Rolls-Royce company did not start to study turbofan engines, and they did not officially start the research of this project until 1950.

The purpose of Fang Lang is to take the lead in completing the research and development of turbofan engines.

Of course, this kind of confidential information Rema Horton has no way of knowing, but since what Fang Lang said is reasonable, he can't have any doubts, if it is really like what Fang Lang said, the turbofan engine has such great benefits, it must be very practical.

After thinking silently in his heart for a while, he raised his head a little embarrassedly and said embarrassedly to Fang Lang:

"Boss, but I'm not familiar with Mercedes-Benz's engine researchers!"

Hearing this, Fang Lang scratched his head a little helplessly, you guy doesn't look very smart! It's no wonder that someone Kurt Tanck can take an entire company's design department with him, while you can only flee alone.

Fortunately, I have a cooperative relationship with Mercedes-Benz, although I don't know whether the people in the automobile R&D department and the aircraft engine R&D department are familiar with it, but I can only try.

"Then I'll get in touch! It seems that our power laboratory needs to be further expanded! ”

Seeing that the Rhema Horton in front of him was a little unreliable, Fang Lang could only add another fire and draw the appearance of the civil airliner he had seen in later generations on the drawings in front of him.

Of course, Fang Lang is not a professional aviation professional, and can only depict the aircraft shapes he has seen the most, and he has the most contact with Boeing 737 and Airbus A320 series.

To a layman like him, the difference in appearance between the two aircraft is not particularly huge, and even the layout of the engines is the same under the wing.

However, there are certain differences in the tail and wing, but the difference is not particularly huge. Therefore, Fang Lang could only slightly combine the two according to his impression, and as for whether it was accurate, Fang Lang did not dare to guarantee it.

However, Fang Lang drew a separate schematic diagram of the cross-section of the wing, which was introduced in a video that he accidentally saw when he was watching a short video in his later life, what is the technology of supercritical wings.

】

It seems to be a very remarkable technology from Airbus.

As for the other aspects, he didn't know much about it, and even in the aerodynamic layout, it was necessary for Rhema Horton and them to go to the wind tunnel to blow it to know if it was suitable.

However, even if it is such a concept map, Fang Lang believes that it can save them a lot of detours and directly lead the trend of private aviation.

As Fang Lang's drawings gradually took shape, Rhema Horton's eyes were staring at him, and I have to say that this aircraft looks very beautiful. The slender fuselage and the slightly upturned wing tips look very beautiful.

The arrangement of two engines suspended on the wings reminded him of the German heavy bombers. The shape of the swept wing reminded him of the TA-183 project, and he knew that this technology was the first of its kind by Professor Kurt Tanck.

Now he was of course very surprised to see him appear on the civil airliner, after all, he hadn't heard the conversation between Fang Lang and Kurt Tanke today, so he directly wondered:

"This kind of swept wing layout will cause the wingtips to stall, is your design suitable?"

Hearing this, Fang Lang smiled and said:

"Don't worry, I've had a serious discussion with Professor Kurt Tanck today, and we've found a way to overcome it.

When the time comes, you and Professor Tan Ke will communicate more. ”
