When Zhang Tie slowly and steadily drove the human-powered plane down from the sky, a large number of people suddenly surrounded it.
As a citizen of the Republic of Hernand, being able to see all the miracles related to gliders here in a short period of time, the engineers of this glider base in the Republic of Hernand really feel that they are so happy.
A few months ago, Zhang Tie created a miracle while running here, and today, Zhang Tie created a miracle while sitting down. Compared with the first miracle, this second miracle is even more exciting.
.
"Can the weight of this human-powered aircraft be reduced further?" Zhang Tie asked the experts from the Republic of Holland after getting off the human-powered aircraft.
"We have now used very expensive lightweight alloy materials to manufacture this human-powered aircraft. In terms of the appearance of this human-powered aircraft, although it is similar to the Windtalker, in fact, in terms of internal and external structural composition and materials,
We have done a lot of optimizations. It is precisely because of these optimizations that we have been able to add a transmission gear set and some control mechanisms and mechanisms inside this human-powered aircraft, and at the same time reduce the weight of this human-powered aircraft to 670 kilograms.
This is already the limit." An expert explained to Zhang Tie.
Following the expert's explanation, Zhang Tie realized that in the Republic of Hernandez, a country that loves flying, someone had actually proposed the concept of manufacturing a human-powered aircraft a long time ago, and many people had fantasized about using bicycles to do so.
The glider provides a power source, turning the glider into a true human-powered aircraft.
In fact, all those who proposed this idea failed in the end. There were two main reasons for their failure. The first was that the human-powered aircraft produced was too heavy. Almost no one could make such a human-powered aircraft truly fly.
The second reason for flying into the sky is that even if a very light-weight human-powered aircraft can be barely made, the flight performance of that human-powered aircraft is completely useless, even worse than a glider. No one in the Republic of Hernandez thinks that is the case.
Human-powered aircraft can be considered aircraft.
A few years ago, the Republic of Holland built a human-powered aircraft using canvas and some light alloy materials. After the manufacture, the weight of the human-powered aircraft was successfully controlled within 150 kilograms, and during the test flight
, the best result achieved by that human-powered aircraft was that it successfully flew thirty-seven kilometers at an altitude of less than five meters above the ground.
After the failure of the test of that light human-powered aircraft, engineers and glider enthusiasts in the Republic of Hernandez came to the conclusion that the human-powered aircraft of this era must be based on excellence, with excellent lift-to-drag ratio and
The structure of a glider with an aerodynamic layout makes sense. The weight of a glider that meets these conditions is generally more than 700 kilograms. If it can continuously drive and fly such a human-powered aircraft, its requirements for the driver are:
It's not ordinary high. In addition to being a top master at controlling gliders, the pilot must also possess immense strength and endurance.
It can be said that later on, what really determines whether a human-powered aircraft can fly into the sky is no longer whether such a human-powered aircraft can be built, but whether a person can be found who can fly such a human-powered aircraft.
The Republic of Hoenn is just a pocket country, and its total population is not as large as that of Black Flame City before. In such a pocket country, masters above level 10 are very, very rare.
To describe Zhang Tie's advantage in one sentence, that is, no one with greater strength and endurance than him can fly a glider, and those who can fly a glider have less strength and endurance than him.
In the eyes of many experts, glider sports are a low-end, civilian sport. Those who really like this sport are ordinary people. There are very few people who are strong warriors or above to play idle and boring games.
In the eyes of ordinary people, playing glider is a sport, but in the eyes of experts, it is just like playing mahjong. It is a completely boring pastime. If you really have that kind of effort, try to break through to the next level as soon as possible.
Or an advanced knight, which is better than anything else.
It was precisely under the combined effect of these various factors that Zhang Tiecai became the first person in this era to fly a human-powered aircraft into the sky by his own strength.
After moving 1,000 full-effect medicines from the Idiot airship and leaving them at the Hern Republic glider base as a token of his gratitude, Zhang Tie left the glider base.
Experts and engineers from the Republic of Holland built a total of three human-powered aircraft for Zhang Tie this time. But one of them was a demonstration aircraft. Although it could fly, there were still some things that were not perfect, so it was left as a glider.
At the base, Zhang Tie took away the two final versions of the aircraft, as well as a bunch of detailed manufacturing drawings and some parts for replacement and maintenance.
The only thing that you need to pay attention to in a human-powered aircraft is the transmission gear set inside the aircraft. However, just pay attention to maintaining the gear set with lubricating oil. When it comes to replacement, according to the experts and engineers of the Republic of Hernandez, even Zhang Tie
I ride a human-powered aircraft around the sky for ten hours every day, and the gear set inside the human-powered aircraft will not have any problems within ten years - that gear set is the most sophisticated industrial product from the Eastern Continent, and its durability is
And the accuracy is on the same level as the gears on the differential engine.
After spending almost a whole day at the glider base in the Republic of Hernandez, when Zhang Tie returned to the Crystal Battle Castle on the Fool, there were already two bright moons hanging in the sky.
Major General Ford had been waiting for Zhang Tie at the Crystal Battle Castle for four hours. Almost as soon as Zhang Tie came back, Major General Ford boarded the Idiot airship.
…
Zhang Tie and Fu Fu met again in the airship's command room.
"Hello, Major General Ford, it looks like you have brought me a gift?" As soon as he saw Major General Ford, Zhang Tie's eyes were fixed on the box that Major General Ford was carrying.
, it was a metal box, and there was a metal chain on the box that was fastened directly to the wrist of Major General Ford's right hand like a handcuff. It looked very valuable.
Major General Ford glanced at Zhang Tie, put the box on the table, entered the password to open the box, and then took out a diamond-shaped crystal also covered with a silver metal shell and handed it to Zhang Tie.
Zhang Tie didn't say anything. After taking what looked like a secret book in his hand, he poured his mental power into it. In an instant, several large Chinese characters appeared in Zhang Tie's mind - "Five Elements and Earth Image Sutra".
…
PS: First of all, I would like to thank the Book Friends God for your support of Tiger, thank you!
Let’s talk about Tiger’s affairs these days. Like all Chinese people, my wife and daughter have been on vacation these days, but they took their vacation earlier. On the 29th, my wife asked for leave from the company, and my daughter asked for leave from the kindergarten.
, the wife wants to go back to her parents’ home, and the daughter wants to experience nature with her friends, so the tiger is caught in its prime. The travel plan is to stagger the peak hours and try to save time on the road.
The young man went with his computer and was prepared to take care of both ends. So on the 29th and 30th, although Tiger was on the road, he still tried his best to make time to update. However, on the 1st and 2nd, he could not take care of both ends. He could touch every day in these two days.
The computer time does not exceed 30 minutes. Even connecting to the Internet and explaining it to everyone is a luxury, so I stopped updating for two days. I hope everyone understands that I will make up for what I owe in the past few days.
