Chapter 608 : Chapter 18 The Birth of the Human-Personal Plane - Castle of Black Iron

Ever since Zhang Tie was chased and killed by the Winged Demon last time driving a glider, and he had to drive the glider into the water to escape, the engineers at the glider base in the Republic of Horn have been busy helping Zhang Tie build a new glider .

In order to manufacture a new glider for Zhang Tie, Colonel Hauersen, the chief officer of the base, even contacted the country in person. The Herne Republic finally sent a team of experts to Cerne with equipment and tools from several train cars. s.

Zhang Tie didn't know it at the time. When he found out, the expert team from the Hern Republic had already arrived. Zhang Tie was a little embarrassed about the mobilization of the Hern Republic. His fame, in the Republic of Horn, is actually very famous.

After the matter about him and the glider base spread to the Hern Republic, and after the Hern Republic’s domestic media played up it, almost every citizen of the Hern Republic knew that in the Sernes War Zone, there was a person who had acquired the Sernes The brave air cavalry with the honorary title of Eagle are flying the glider of the Horn Republic in battle, and they have achieved a lot of fruits, which made the winged demons of the demon race fearful.

In the current Herne Republic, Zhang Tie is definitely an idol.

Therefore, after Zhang Tie's second glider crashed, the Hern Republic, who learned of the situation, raised the matter to the height of national honor and sent a very strong team of experts to Cerne with equipment and machines Si, to build a brand new glider for Zhang Tie.

In the words of Colonel Hauersen, it is the honor of the entire Herne Republic that the Eagle of Cernes can drive a glider of the Herne Republic to fight for the protection of the human race in the sky.

At that time, after the expert team from the Hern Republic came to Cernes, they met Zhang Tie twice and had some communication with Zhang Tie, because it was the rainy season at that time, and when flying a glider in the sky, thermals would often be lost. The power brought by it, and the weather is also a great test for this unpowered flying device. When the experts in the Hern Republic asked Zhang Tie what kind of glider he needed, Zhang Tie once told those experts that a paragraph.

"For me, the wind and air currents in the sky have been able to use them to the extreme. In this regard, I think it will be difficult for you to help me make breakthroughs, but the situation on the battlefield is very complicated. Sometimes, as in the past In the past two months, due to the heavy rain, when I cannot take advantage of these natural conditions, as a glider driver, I will be very passive on the battlefield, and flying a glider will become a very dangerous thing, if I can , I hope that the glider I will drive in the future can also have other power sources when I can't rely on airflow and wind. Can I let the glider fly freely in the sky like pedaling a bicycle? This is my request.

When Zhang Tie said this, he didn't imagine whether the expert team in the Hern Republic could do it. He just said what he wanted. If those people couldn't do it, Zhang Tie couldn't do it. What will be lost, if it is achieved, it will definitely be a huge surprise for Zhang Tie, which means that he will be more free in the sky.

A few days after he said this, the expert team of the Hern Republic invited Zhang Tie to the glider base for two very comprehensive physical fitness tests.

Zhang Tie didn't know the relationship between flying a glider and his physical fitness at the time, but he went anyway. During the physical fitness test, he only remembered that the members of the Herne Republic's expert team looked at him with bright eyes... …

Since then, the expert team of the Hern Republic rarely contacted Zhang Tie at the glider base,

It was not until these two days that Zhang Tie was notified that a new glider had been manufactured and he was asked to take a look.

On the 7th of July, the glider base of the Hern Republic...

Zhang Tie once again appeared in a hangar of the base. The final product, which took dozens of expert engineers and hundreds of technicians from the Herne Republic for more than a month, appeared in front of Zhang Tie.

The appearance of that glider is somewhat similar to that of the Windtalker II, but the biggest difference between the whole glider and the Windtalker II, or the biggest difference with all gliders, lies in its head, which has an extra Biplane propellers.

Zhang Tie sat in the cockpit and found that the layout and settings in the cockpit had also completely changed. The steering pedal under his feet was gone, replaced by a mechanism similar to the pedals of a bicycle, and there were some changes on the elevator. Zhang Tie found out that the elevator of the previous glider could only be pulled up or pressed down, but Zhang Tie found that in addition to being able to pull up and push down, it can also be like the steering wheel of a car. Turning the left and right sides about 90 degrees, there is an extra push rod of unknown purpose under the elevator.

In addition to these, the whole glider still retains a very obvious Zhang style-the seat of the glider is foldable, and there are still two seats on the left and right sides of the cockpit that allow him to "lift" the glider with his hands. The concave handle, the bilge cover of the glider cockpit is still slidable.

Zhang Tie looked around in the cockpit of the glider with some excitement, and finally couldn't help but put his feet on the pair of bicycle pedals and started to move, wanting to see what effect it had.

For ordinary people, it may be very strenuous to step on that pedal, and those with lesser strength may not be able to step on that pedal many times with all their strength, but for Zhang Tie, he steps on that pedal. I feel that it is really not much more difficult than ordinary people riding a bicycle.

As soon as the pedal was stepped on, the two propellers at the nose of the glider began to spin with a whirring sound. Zhang Tie's feet slowly increased the speed, and the propeller at the nose of the glider rotated faster and slowly. Yes, Zhang Tie found that the entire glider started to move, and began to slide slowly forward on the ground.

When the glider was running in the hangar, Zhang Tie's heart moved, and he operated the rudder to turn to the right. When the glider was sliding, it also started to slide to the right. Zhang Tie operated the rudder to turn to the left. Start turning left.

Zhang Tie was very excited. He finally understood the thoughts of the experts in Hern Republic. Since the propeller can push the glider on the ground to make the glider move forward, then this thrust also exists in the sky. The extra power you can get in the sky.

Zhang Tie jumped out of the stance cabin of the glider, and happily asked the experts and engineers of the Herne Republic, "How did you do it?"

"What you said to us at the time gave us a lot of inspiration and inspiration. After serious thinking, we borrowed the design ideas of early human aircraft before the catastrophe, and used a variable speed gear set and chain to step on your feet. The power generated when the pedals are moved is transmitted to the front propellers, giving this glider the ability of the early human aircraft before the catastrophe, and it can get extra power when the glider cannot rely on the updraft and wind."

"Thank you, you are truly amazing!"

"Such a glider is specially designed and manufactured for you. If it is replaced by someone else, such a design may not be very useful to them, because their strength and physical strength may not be able to support such a flight for a long time. Remember the test we did on you earlier, we found that the strength in your legs is very powerful, and your physical strength and endurance are also extraordinary, if you convert the strength in your legs into the power of the machine, your double The legs are roughly the equivalent of a good 20-horsepower engine, and that's why we came up with this idea."

"Ah, the power on my feet is equivalent to the power of a 20-horsepower engine, and how much is that?"

"Ordinary people who don't ignite the light can generally produce a maximum power of only one horsepower in one minute, and within ten minutes, the maximum power that ordinary people can produce is only about half a horsepower. The so-called 20 horsepower engine Power, roughly speaking, is equivalent to when you are lying down, your feet are against a 1500 kg object, and within one second, the object is lifted by one meter, and it can be repeated continuously This process. This is not an instant explosive force, but a continuous and repeated force. In terms of explosive force, many people can easily exceed 1,500 kilograms on both feet, but if a person is required to do it for half an hour or There are very few people who can repeat the process of raising a 1,500-kilogram object by one meter in one second with both feet within one hour."

"Oh, so that's how it is!" Zhang Tie suddenly realized, he didn't expect his feet to be able to match a 20-horsepower engine at this moment, which made him a little proud. Not everyone has such an ability.

"Can I step on this pedal now to make the glider fly directly into the sky?"

"Although we have set up an assistant device that uses the pedals to drive the glider to run, the requirements for your strength will be very high, but if you reach the sky, the situation will be different. As long as your physical strength can support you, let The propeller maintains a minimum speed of more than 800 revolutions per minute, and it can provide a steady stream of power for this glider, so that this glider still has very good flight and handling performance regardless of weather conditions. We think Now, this glider can no longer be called a glider, but should be called a human-powered plane!"

"Human-powered aircraft, the name is very interesting!" Zhang Tie laughed. Thinking of the former aircraft brotherhood, Zhang Tie felt that such things as aircraft seemed to be too predestined for him, and he did not expect that he could really fly an aircraft now.

"Can I try it now?"

"certainly!"

"I still don't understand what the push rod under the elevator is for. I see that there are several numbers written here, which are 50, 30, 15 and 5. There is also a space and a ground. What does this mean? "

"This is the transmission lever. It can adjust the speed ratio between the power pedal and the propeller and the power output direction of the pedal under your foot. There are two power output directions and four gears. Among the four gears, the highest The gear position means that you can turn the propeller of this human-powered aircraft 50 times by stepping on the pedal a circle, the next gear is 30 times, and so on, the higher the speed ratio, the force you need to step on a circle The higher it is, it can be flexibly adjusted according to your physical strength, and the empty space and the ground represent the power output direction of the pedals, and the empty word corresponds to the power transmission to the front propeller when you step on the pedal, providing the glider with a The power in the air, and the word ground, means that when you step on the pedal, the power will be transmitted to the landing wheels on the glider, just like riding a bicycle, let the glider run on the ground..."

A few minutes later, after Zhang Tie thoroughly understood how the so-called human-powered plane was operated, the human-powered plane was pushed onto the runway.

Zhang Tie sat in the cockpit again, without even thinking about it, he pushed the shift lever to the floor position, and then stepped on the pedal hard with his feet...

There was no tractor towing, and Zhang Tie didn't lift the glider to run. Zhang Tie just stepped on the pedal like riding a bicycle, and the speed of the glider on the runway became faster and faster. Finally left the runway and flew into the sky...

After flying into the sky, Zhang Tie pushed the gear to the 50 position below the empty character, and then began to step on the starting power pedal quickly, and the front propeller quickly turned,...

In the end, Zhang Tie relied on the strength of his own feet without the help of wind and updraft, so that the human-powered plane really flew freely in the sky like an airplane.

For Zhang Tie, the feeling of flying this human-powered plane in the air is really indescribable. If he is flying an ordinary glider, he needs to pay attention to the direction of wind and airflow at all times. But when driving this man-powered plane, Zhang Tie feels really free, completely free in the sky.

In Zhang Tie's opinion, this thing can't be called an airplane at all, but should be called a sky bicycle. As long as the body still has strength, as long as the pedals under the feet are constantly stepped on, this human-powered airplane can fly in the sky. Fly freely.

When flying freely, Zhang Tie can fly it as a glider when encountering an updraft that can be used, so that he can take a rest and recover his strength. When there is no airflow available, Zhang Tie Stepping on it again, it can still let it fly as it wants, without considering the influence of the weather.

If Zhang Tie stepped on the power pedal while flying with the airflow, and let the propellers work together, Zhang Tie found that his flying speed could be increased by about 20 to 30 percent.

With such a manpower plane, Zhang Tie is more confident in the task he promised to take over...

ps: On the earth, human-powered aircraft powered by human power can fly more than 100 kilometers in the 1980s. Have you ever thought that one day the human-powered aircraft competition will become an Olympic event? Ha ha……
