People from the military have their own stands. Perhaps because of the presence of military people, every inventor of the aircraft seemed very excited.

In the past, the military gave grants to some inventors in the field of hot air balloons to allow them to continue to deepen their inventions. To be honest, these practices made many inventors of non-hot air balloon aircraft drool with envy. Now their opportunity has come.

After Mr. Trueman said a few words to Lynch, he went to the corner to talk quietly with the military personnel. They were discussing some ideas of several inventors who had attracted their attention.

In fact, after the submarine was invented, the military did not take it out immediately. It has been thinking about how to counterattack the submarine.

It's not just the Federation that has submarines. In fact, other countries with more advanced science and technology, such as Gefra, also have submarines.

It’s just that the Federation may be the first country to turn underwater equipment that has always been used for civilian use into weapons of war. Once these submarines begin to show their ferocious and sharp claws in the Eastern Ocean, other countries will soon follow.

Enter.

Sometimes with the changes of the times and the advancement of science and technology, what is missing is an idea and a flash of inspiration.

After many tests, when observing the sea surface from the perspective of standing on a ship, the submarine hidden in the water cannot be seen at all due to the influence of light. However, if it is at a higher angle, the visual difference caused by the refraction and reflection of light on the sea surface can be reduced.

, people can spot submarines under the sea with just their naked eyes.

So in the past two years, the military has allocated a lot of money to hot-air balloon inventors who they think are not necessarily valuable, but can be brought to the battlefield anytime, anywhere, and have developed a balloon that can be loaded on ships and used anytime, anywhere.

The "Quick-Ascent Observation Hot Air Balloon" project for rapid ascent and observation.

But the military has always believed that hot air balloons cannot solve these problems very well. First of all, hot air balloons are easy to be shot down. Even if they already have armored hot air balloons, they can still be shot down easily.

Secondly, once the hot air balloon cannot stay in the air for a long time and becomes a consumable, it will have to be equipped with more hot air balloon equipment and occupy more space on the ship. Once the hot air balloon is used up, the submarine will become a big killer.

.

Therefore, the military has set its sights on non-hot air balloon aircraft, perhaps they can solve this problem.

After Mr. Trueman talked with the military personnel for a while, he sat back next to Lynch, and at this time the aircraft exhibition also began.

The first thing that appeared was a very standard fixed-wing aircraft, at least it was very close to the aircraft that Lynch remembered.

The designer of this fixed-wing aircraft is a well-known inventor in the field of aircraft invention. He first asked his assistant to drag the aircraft around the scene, while he himself stood on the edge of the stand and explained to everyone

Introducing your new design.

"...I used more aluminum alloy in this design. Metro Industries innovated their aluminum alloy formula last year, allowing the new aluminum alloy to reduce its weight while slightly increasing its strength..."

"...Referring to some of the problems we encountered in the previous design, we made modifications accordingly. We expanded the wingspan and at the same time wrapped the wings with sheepskin..."

The method of wrapping the wings of an airplane with real leather... is really amazing. Lynch found it funny when he heard it, and some people even laughed out loud.

Of course, some people are not so happy, not this inventor, but other inventors who have not yet had a chance to show off their works.

Everyone knows the value of the "golden idea" in invention and creation, but its greater value is reflected in the process of deceiving laymen and investors. The inventor who put armor on a hot air balloon just proposed this idea.

He received a large amount of funds for him to realize it.

This shows how important "I have an idea" is to them.

Wrapping aircraft wings in leather is not a bizarre idea. Some people even inserted feathers into aircraft wings before. The reason for this phenomenon must be that it is effective.

There is still no perfect aerodynamics suitable for promotion, and people are still exploring this aspect. However, some private inventors have discovered through continuous experiments that the stability of some animal leather is higher than that of leather during specific use.

Wooden aircraft wing without any coating or outer covering.

They may not know why it works, but they know the benefits.

The inventor continued to explain why he wanted to wrap the wings of the aircraft with a layer of sheepskin. After introducing a lot of data, Lynch roughly understood part of the content.

To put it simply, this design is now lighter than before, more stable when flying in the air, and after redesigning and adjusting the center of gravity, the chance of an accident during landing is also smaller.

He also listed some hypotheses, such as replacing more advanced engines to make the aircraft fly faster, for example, if he could get more funds, he could completely replace the wooden structure in the aircraft design with aluminum alloy...

In short, in his opinion, this aircraft is almost perfect!

Then the inventor and his assistant started the test flight. They had already made preparations before the exhibition started. When they parked the plane at the end of the runway, people in the stands gradually stood up.

This is an exciting time. Human beings' desire and dream to conquer the sky have existed since the birth of human society.

People in ancient times always imagined that humans could fly like birds. Now, federal inventors are making continuous progress on the road to conquering the sky every year.

The plane successfully flew after accelerating, and Lynch was a little surprised, "It's flying!"

Mr. Trueman was very calm, "Yes, it can fly. People could do this ten years ago, but until now, all we can do is fly."

He didn't act as excited as others, he was very calm, and even gave people a feeling of disappointment.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Aircraft have long existed and can fly, but what they can do is that they can fly.

After flying a few kilometers, he fell down. If he was lucky, the pilot would survive to design the next aircraft. If he was unlucky, his work would be destroyed together. There was a time when some people thought that these aircraft inventors were all liars, defrauding investors of their funds.

, what we create is useless, and there are also terrible dangers.

These situations still exist until now. Taking off is easy, landing is always a big problem, and so is the flight distance.

In order to make it easier to take off and fly further, it is important to ensure the total weight of the aircraft. In addition to its own structure, the current largest aircraft can only carry two thin pilots into the sky.

So so far, this may indeed be an industry full of potential, but people still can't see the future in the short term.

Compared with a fast-rising hot air balloon that costs thousands of dollars, a plane that costs tens of thousands of dollars and costs a life seems even less suitable for use in war.

This is also the reason why Lynch subconsciously described Mr. Trueman's description of the aircraft field as "dangerous" at first, mistakenly believing that these inventions were for war, but Mr. Trueman did not agree.

These planes may have no other use than suicide.

Military evaluators are still evaluating, evaluating the shortest acceleration distance for takeoff, evaluating the speed of takeoff, evaluating the angle of takeoff, and evaluating how stable it is when flying in the air.

In the past two years, there was an accident where an aircraft vibrated violently while flying in the air, eventually leading to a direct disintegration. Stability has become one of the criteria for the quality of an aircraft.

Those watching the excitement cheered, but the inventor in the sky began to sweat. He had shown everything he needed to show, and he should land next.

Today's aircraft have two ways to land. If you are confident in your aircraft design, you can land on the runway. This is one of the reasons why the flying wings of fixed-wing aircraft are still wooden. People need its toughness and stretch when gliding.

Performance brings some convenience.

Another way is to land in a grain pile and bet that you won't be crushed to death by the engine or beaten to death by the broken propeller.

In the end, the inventor chose to land on the runway. If he wanted to get funding from the military, he had to land on the runway.

The plane adjusted its angle and height and began to slow down, and people in the stands were nervously clenching their fists.

When the plane's front wheel made contact with the ground, the sound of a flat tire spread throughout the stands. The soldier responsible for evaluating the aircraft directly gave the aircraft a big "X".

But fortunately, the problem at the back was not big. After the front tire blew out, it quickly deformed, the landing gear broke, and after the collapse, the fuselage fell heavily to the ground.

The balance of the aircraft is good. If any wing of the aircraft touches the ground, it is likely to be another plane crash with fatalities, although from the current perspective, this is also an accident.

The inventor stood in front of the stand as if he had just been fished out of the bathtub. He even forced a smile on his face and said, "It is...safe, and I proved it!"

Mr. Trueman shook his head. He was disappointed and had no illusions about what happened next.

At this moment, Lynch suddenly interjected, "Maybe it's because of the runway, which is not flat enough."

Mr. Trueman looked at him curiously, "Do you know this too?"

Lin Qi smiled and said nothing. Neither of them took this matter to heart.

In some later aircraft demonstrations, the contents displayed were basically the same, just doing some work on the wings of the aircraft, until Lynch saw a rotor-wing aircraft appear.

It was a flight cabin that looked like a large egg. The pilot sat on the engine and used the transmission rod to rotate the propeller directly above the aircraft in an attempt to use lift to lift the flight cabin.

Mr. Trueman looked at it very carefully, which was also the purpose of his coming here. This may not be the first rotary-wing aircraft in history, but its degree of completion is very close to the helicopter in Lynch's impression.
