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 was running here to create a miracle, and today, Zhang Tie is sitting and creating a miracle, and this second miracle is more exciting than the first miracle.

"Can this human-powered aircraft be lighter?" As soon as he got off the manpower plane, Zhang Tie asked those experts in the Republic of Hoane.

"Now we have used very expensive light alloy materials to manufacture this human-powered aircraft, 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, we have also reduced the weight of this human-powered aircraft to 67o 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 Horn once used canvas and some light alloy materials to build a human-powered aircraft, and the weight of the human-powered aircraft was successfully controlled within 15o 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 tests of that light human-powered aircraft, the engineers of the Republic of Hhorn and glider enthusiasts came to a conclusion - the human-powered aircraft of this era. It 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 7oo kilograms, and it can continuously drive and fly such a human-powered aircraft, and its requirements for the pilot are not generally high. In addition to being a top glider. It also requires unparalleled 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 Black Flame City before, in such a small country. Masters above level 10 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 are a low-end, civilian sport, and those who really like this sport. Most of them are ordinary people, and there are very few people who are above the strong warrior who will go idle and bored to play what glider, in the eyes of ordinary people, playing glider is sports, but in the eyes of masters, it is purely the same as playing mahjong, it is completely a boring pastime, and it really has that bit of effort. Strive to break through to the next level or advanced knight one day sooner, which is stronger 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 1ooo full-effect potions from the Fool airship and leaving them to the Hangder Base of the Republic of Hhorn as his thanks, Zhang Tie left the Glider Base.

The experts and engineers of the Republic of Hhorn built a total of three human-powered planes for Zhang Tie this time. But one of them is a verification aircraft, although it can also fly, but there are still some places that are not too perfect, so it is left in the glider base, Zhang Tie took away the last two of the finished 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 variable gear set inside the aircraft, but the gear set usually pays attention to the maintenance with lubricating oil, when it comes to replacement, according to those experts and engineers in the Republic of Hoane, even if Zhang Tie steps on the human-powered plane to the sky for ten hours every day, the internal gear set of the human-powered aircraft will not have any problems within ten years - the gear set is the most sophisticated industrial product from Dongfang Da 6, 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 the way you look, 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 handcuffs, 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 secret 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 - "Five Elements Earth Image Sutra".

……

ps: First of all, thank you for the support of the tiger from the entrustment of the book friend God, thank you!

Let's talk about the tiger these days, like all Chinese, the wife and daughter have been on holiday these days, but they have taken the holiday earlier, on the 29th, the wife asked for leave from the company, the daughter asked for leave from the kindergarten, the wife wants to go back to her mother's house, the daughter wants to feel the nature with her little friends, the tiger was caught, the travel plan is to stagger the peak, try to save time on the road.

Zhuang Ding is going with the computer, ready to take care of both ends, so on the 29th and 3o, although the tiger is on the way, but still try to seize the time to update, but the 1st and 2nd, both ends can not be taken care of, these two days can touch the computer every day for only 3o minutes, even connecting to the network to explain to everyone is called a luxury, so it stopped for two days, I hope you understand, these days owed back the tiger will make up.
