When Zhang Tie slowly drove the human-powered plane down from the sky, a large number of people surrounded it at once.
As a citizen of the Republic of Horn, I can see the miracles related to gliders here in a short period of time, and the engineers of this glider base in the Republic of Horn feel so happy.
A few months ago, Zhang Tie created a miracle by running here, and today, Zhang Tie created a miracle while sitting, and this second miracle is even more exciting than the first miracle.
"Can the weight of this human-powered aircraft be reduced a little more?"
As soon as he got off the human-powered plane, Zhang Tie asked those experts in the Republic of Hohn.
"Now this human-powered aircraft has been manufactured using very expensive lightweight alloy materials, in the shape of this human-powered aircraft, although it is similar to the wind whisperer, but in fact, in the internal and external structural composition and materials, we have done a lot of optimization, it is precisely because of these optimizations that we can add a variable gear set and some control mechanisms and mechanisms inside this human-powered aircraft, and at the same time, the weight of this human-powered aircraft has been reduced to 670 kilograms, which is already the limit."
An expert explained to Zhang Tie.
With the expert's explanation, Zhang Tie learned that in a country like the Republic of Hoane, which loves flying, in fact, a long time ago, someone proposed the concept of human-powered aircraft, and many people fantasized about using the method of pedaling bicycles to provide a power for the glider, so that the glider can become a real human-powered aircraft.
In fact, all the people who put forward this idea failed in the end, and there are two main reasons for its failure, the first is that the human-powered aircraft manufactured is too heavy, and almost no one can make such a human-powered aircraft really fly into the sky, and the second reason is that even if a very light human-powered aircraft is barely manufactured, the flight performance of that human-powered aircraft is completely like chicken ribs, and even a glider is inferior, and the people of the Republic of Hhorn do not think that such a human-powered aircraft can be regarded as an airplane.
A few years ago, the Republic of Hhorn had made a human-powered aircraft out of canvas and some light alloy materials, and the weight of the human-powered aircraft was successfully controlled within 150 kilograms after it was manufactured, and during the test flight, the best result achieved by the human-powered aircraft was that it successfully flew 37 kilometers at an altitude of less than five meters above the ground.
After the failure of the test of the light human-powered aircraft, the engineers and glider enthusiasts of the Republic of Hhorn came to a conclusion that the human-powered aircraft of this era must be built on the basis of an excellent glider architecture with an excellent lift-to-drag ratio and aerodynamic layout to make sense, and the weight of a glider that meets these conditions is generally more than 700 kilograms, and it can continuously drive and drive such a human-powered aircraft, and its requirements for the pilot are not ordinarily high.
In addition to being a top glider, the pilot must also possess great strength and stamina.
It can be said that in the future, what really determines whether a human-powered aircraft can go to the sky is not whether such a human-powered aircraft can be manufactured, but whether it can find such a person who can fly such a human-powered aircraft.
The Republic of Houn is only a pocket country, and the total population is not as large as that of the previous Black Flame City, and in such a small country, masters above level ten are very, very rare.
In one sentence to describe Zhang Tie's advantage, that is, those who are stronger than him in strength and endurance do not have him who can fly gliders, and those who can fly gliders do not have as much strength and endurance as him.
And in the eyes of many masters, glider sports is a low-end, civilian sport, really like this sport, most of them are ordinary people, few strong warriors above the person will go idle and boring to play what glider, in the eyes of ordinary people to play glider is sports, but in the eyes of the master, it is purely the same as playing mahjong, it is completely a boring pastime, really have that bit of effort, and strive to break through to the next level or advanced knight as soon as possible, better than anything else.
It is under the combined effect of these various factors that Zhang Tie became the first person in this era to fly a human-powered plane into the blue sky with his own strength.
After removing 1,000 full-potency potions from the Fool airship and leaving them for the Horn Republic Glider Base as his thanks, Zhang Tie left the Glider Base.
The experts and engineers of the Republic of Hoen built a total of three human-powered planes for Zhang Tie this time, but one of them was a verification aircraft, although it could also fly, but there were still some places that were not too perfect, so they stayed at the glider base, and Zhang Tie took away the two of the last completed version, as well as a bunch of detailed manufacturing drawings and some parts used to replace maintenance.
The only thing that needs to be paid attention to in the human-powered aircraft is the gearset inside the aircraft, but the geargroup usually pays attention to the maintenance with lubricating oil, when it comes to replacement, according to those experts and engineers in the Republic of Honn, even if Zhang Tie steps on the human-powered plane to the sky for ten hours every day, the geargroup inside the human-powered aircraft will not have any problems within ten years The geargroup is the most sophisticated industrial product from the Eastern Continent, and its durability and accuracy, With the gear on the differential machine is a grade thing.
After staying at the glider base in the Republic of Horn for almost a day, by the time Zhang Tie returned to the Crystal Battle Fort on the Fool, there were already two bright moons hanging in the sky.
Major General Fude had been waiting for Zhang Tie for four hours at the Crystal Battle Fort, and almost as soon as Zhang Tie returned, Major General Fude boarded the Fool airship.
Zhang Tie and Fu met again in the command room of the airship.
"Hello, Major General Fude, looking at your appearance, it seems that you have brought me a gift" As soon as he saw Major General Fude, Zhang Tie's eyes were fixed on the box that Major General Fude was carrying, it was a metal box, and there was a metal chain on the box that was directly buckled on the wrist of Major General Fude's right hand like a handcuff, which was very valuable.
Major General Fu glanced at Zhang Tie, directly put the box on the table, entered the code to open the box, and then took out a diamond-shaped crystal that was also wrapped in a layer of silver metal shell and handed it to Zhang Tie.
Zhang Tie didn't speak, and after taking the thing that looked like a cheat book in his hand, a spiritual power punched into it, and in an instant, several big characters in Chinese appeared in Zhang Tie's mind
