The people of the military have their own stands, perhaps because of the presence of people from the military, and every inventor of the aircraft seems to be very excited.

The military had given grants to some of the inventors in the field of hot air balloons to continue to deepen their inventions, and to be honest, these practices made the inventors of very non-hot air balloon aircraft drool with envy and jealousy, and now their opportunity has come.

Mr. Trueman and Mr. Lynch spoke a few words before going into a corner with the military to whisper a conversation about some of the ideas of several inventors who had attracted their attention.

In fact, since the invention of the submarine, the military has not taken it out at the first time, but has been thinking about how to counter the submarine.

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

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

Sometimes the changes of the times and the progress of science and technology lack an idea and a light.

After many tests, if you look at the sea surface from the angle of standing on the ship, you will not be able to see the submarine hidden in the water at all, but if you look at it at a higher angle and reduce the visual difference caused by the refraction and reflection of light on the sea surface, people can find the submarine under the sea surface with the naked eye.

So in the past two years, the military has allocated a lot of money to the inventors of hot air balloons who they think are not necessarily valuable, but can be pulled to the battlefield anytime and anywhere, and have come up with a "rapid ascent observation hot air balloon" project that can be loaded on ships and quickly lifted into the air for observation anytime and anywhere.

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 shoot down, even if they already have armored hot air balloons, but they can still be easily shot down.

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

So the military is looking at non-hot air balloon aircraft, maybe they can solve this problem.

Mr. Trueman talked to the military for a while and then sat back down next to Lynch, and the exhibition began.

The first to appear was a pretty standard fixed-wing aircraft, at least it was close to the planes that Lynch remembered.

The designer of this fixed-wing aircraft is a well-known inventor in the field of aircraft invention, and he first asked his assistant to drag the aircraft around the scene, and himself? He stood on the edge of the stands to introduce his new design.

“...... Did I use more aluminum alloy in this design? Mitro Industries revolutionized their aluminum alloy formula last year to make the new aluminum alloy slightly stronger? Weight loss ......"

“...... Referring to some of the problems we had in the last design? Modified for this, we expanded the wingspan? At the same time, the wings of the aircraft were wrapped in sheepskin ......"

Wrapping the wings of an airplane in leather, this practice ...... Really amazing? Lynch thinks it's funny when you hear it? Some even burst out laughing.

Of course, there are also people who are not so happy, not the inventor, but other inventors who have not yet had time to show their work.

Everyone knows the value of "golden ideas" in invention and creation, but its greater value is reflected in the process of fooling laymen and investors? The inventor named Hot Air Balloon Armor just came up with the idea? He got a lot of money for him to make it happen.

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

Wrapping airplane wings in leather is not a bizarre idea, and there have even been people who have put feathers in airplane wings before, and the reason for this phenomenon must be that it works.

Now there is no perfect, suitable for promotion of aerodynamics? People are still exploring this research, but some folk inventors have found that some animal leather is in the process of specific use through continuous experiments? The stability is higher than that of wooden airplanes without any coating and coating.

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

The inventor goes on to elaborate on the reasons why he wrapped the wings of the airplane in sheepskin. After introducing a lot of data, Lynch roughly understood part of the content.

In layman's terms? Is this design now lighter than ever? More stable when flying in the air? After the redesign has adjusted the center of gravity, there is also a smaller chance of accidents during the landing of the aircraft.

He also listed assumptions such as that replacing the aircraft with more advanced engines would make the aircraft fly faster, and that if he could get more money, he could completely replace the wooden mechanisms in the aircraft design with aluminum alloy......

In short, in his opinion, this flying machine is almost perfect!

Immediately after the inventor and his assistant began the test flight, they had prepared for the show before the show began, and when the plane was parked at the end of the runway, the people in the stands gradually stood up.

It was an exciting time, and the desire and dream of human beings to conquer the sky had existed since the birth of human society.

In ancient times, people always fantasized that humans could fly like birds, and now, the inventors of the Federation are constantly advancing on the road to conquering the sky every year.

The plane accelerated and flew successfully, and Lynch was a little surprised, "It flew!"

Mr. Trueman was calm, "Yes, it flew, people could have done this ten years ago, but until now, all we can do is fly." ”

He doesn't act as excited as the others, he's calm, and even a little disappointed.

Flying machines have existed for a long time and can fly, but what can be done is that they can fly.

After flying a few kilometers and falling headlong, if the pilot is lucky to live to design the next plane, if he is unlucky, he will be destroyed with his work, and at one time some people thought that these aircraft inventors were liars, defrauding investors of their funds, and that what they came up with was useless and there was a terrible danger.

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

In order to take off more easily, in order to fly a little farther, it is important to ensure the total weight of the aircraft, and now the largest aircraft can only carry two thin pilots into the sky in addition to its own structure.

So far, this may indeed be an industry full of potential, but people still can't see the future for a short time.

Compared with a fast-rising hot air balloon that costs thousands of dollars, this kind of plane that costs tens of thousands of dollars and costs a life seems to be more unsuitable for use in war.

This is also the reason why Lynch subconsciously described Mr. Trueman as "dangerous" in the field of aircraft at the beginning, and mistakenly believed 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 assessing, assessing the minimum acceleration distance for takeoff, assessing the speed of takeoff, assessing the angle of takeoff, assessing how smoothly it flies in the air.

In the past two years, there was a violent tremor when an aircraft was in the air, which eventually led to a direct disintegration accident, and stability has become one of the criteria for the quality of the aircraft.

The people who watched the excitement cheered, but the inventor in the sky began to sweat, and he had finished showing all he needed, and it was time to land.

Nowadays, there are two ways to land, if you are very confident in your aircraft design, you can land on the runway, which is one of the reasons why the flying wing of fixed-wing aircraft is still wooden, and people need to glide when its toughness and stretching performance bring some convenience.

Another way is to land in a haystack and bet that you won't be crushed by the engine or killed by a shattered propeller.

In the end, the inventor chose to land on the runway, and he had to land on the runway if he wanted to get a grant from the military.

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

When the front wheels of the aircraft made contact with the ground, the sound of a flat tire spread throughout the stands, and the military personnel in charge of evaluating the aircraft directly gave the plane a big "X".

But fortunately, there is not much problem in the back, the front wheel is quickly deformed after the puncture, the landing gear is broken, and the fuselage falls directly to the ground after the collapse.

The plane was well balanced, and if any of the wings touched the ground, it was likely to be another crash, although from the current point of view, it was also an accident.

The inventor stood in front of the stands as if he had just been fished out of the bathtub, and he squeezed out a smile, "It's ...... Safe, I proved it!"

Mr. Trueman shook his head, disappointed and less disillusioned about the rest of the world.

Lynch suddenly interjected at this time, "Maybe it's not smooth enough because of the runway." ”

Mr. Trueman looked at him with some curiosity, "You know this too?"

Lynch smiled and didn't say anything, neither of them took the matter to heart.

In some later aircraft displays, the content of the display was about the same, nothing more than making some fuss on the wings of the plane, until Lynch saw a spiral-wing plane appear.

It was a large egg-like flight compartment, and the pilot sat on the engine and used the transmission rod to rotate the propeller directly above the aircraft in an attempt to lift the flight compartment by lift.

Mr. Trueman looked very carefully, and this is what he came here for, it may not be the first propeller-wing aircraft in history, but its degree of completion is already very close to the helicopter in Lynch's impression.

In the end, though, everyone was disappointed, and despite the hard work of it and its designers, it still didn't fly.
