Chapter 537

For parachute jumping at an altitude of 3600 meters or more, it is necessary to keep a free fall for more than 40 seconds. Ren He thinks this is a huge pit.

If calculated according to simple physics, 40 seconds of free fall time is to fall to the ground, a pool of meat cake, no doubt.

The sky punishment system infuses a huge amount of information about parachute jumping skills into Ren He's brain. These detailed information make sure Ren He's guess is correct. This task is not so simple!

The altitude above 3600 meters does not mean that it is 3600 meters above the ground. In fact, the average altitude of the whole Henan area is 110 meters, that is to say, when the altitude is 3600 meters, the actual distance from the ground is only 3490 meters.

Let's not talk about the altitude of kengdai for the time being. Let's talk about the marked free fall time. If we really follow the 3600 meters altitude and 40 seconds free fall given by the heaven punishment system, Ren He will surely die.

In high altitude, there is air resistance. The falling posture must be parallel to the ground and the legs are completely backward, which is not only the problem of air resistance. If you encounter the updraft on the ground, you don't have a good falling posture. If you start to turn over in the air, then Ren He doesn't even have a chance to open the parachute.

Therefore, when the cross-section of the human body falls freely in the air, it is impossible to simply calculate the acceleration of gravity. The resistance is too big to imagine, and no one has ever measured it.

However, Ren Hetuo an Si confirmed that professional parachutists, the ground altitude is 110 meters, so how many meters altitude parachute, free fall time can reach 40 seconds?

The other side replied, 4600 meters

Nima, Ren He wanted to spray the natural punishment system at that time. The difference was 1000 meters. He really wanted to jump so foolishly, but he didn't want to die?!

Can you be more shameless?

It was with the technical experience instilled in the system of natural punishment that Ren he realized that there was a mistake in the process of parachuting, that is, most people thought that there would be weightlessness when parachuting. Not really.

Parachute jumping is more like swimming, when you fall in the water. In addition, from the perspective of comparative physical science, the sense of weightlessness is that the pressure of the object on the support is less than the gravity of the object. Parachuting is a process of falling according to its own gravity, so there is no sense of weightlessness. Compared with roller coaster and jumping machine, it is very different. Roller coaster jumping machine is the body itself has a speed, and then take your body forward, so the whole person is backward, right. But skydiving is when you fall according to your own gravity, so it feels totally different.

Parachute jumping has always been an extreme sport for people who are eager for freedom. When people fall down freely, their mood will be as empty as ever. That kind of freedom is hard to experience in most other extreme sports.

Parachute jumping has always been one of the extreme sports with the highest mortality, far more than climbing Mount Everest.

All the equipment is ready-made. Before going to the United States, ANFI was asked to prepare this item. Parachute jumping was one of the items Ren he planned to play. In order to buy these equipment, Ren He spent a lot of money, so there is no doubt about its safety.

After such a long time, Ren He just informed an Si to return the equipment to the factory for inspection again. If there is no problem, he can use it directly.

After all, life is only once. It's best to be on the safe side. Who knows these equipment are not the safest after a few months? Anyway, the money has been spent. It's normal to ask for after-sales service.

Now the question is, how can we get to 4600 meters above sea level?

It is reasonable to say that helicopters should be chosen. However, most civil helicopters actually only fly below 3000 meters above sea level. In previous generations, there was even a record that helicopters stopped at the top of Mount Everest without load in 2005. In fact, before China introduced the Black Hawk, helicopters were not even able to fly above 3000 meters above sea level.

Can't Ren He apply to the military to use the Black Hawk? Isn't that the pain of idleness?

What about giving up helicopters and choosing civil aircraft?

In fact, the sky punishment system only gave Ren He parachute jumping skills, but never told him how to prepare for other matters.

China's parachute jumping industry is still relatively backward. The United States is relatively developed, but Ren He can't go to the United States to jump. After jumping to the ground, he may be taken away by the U.S. government. That's a fart.

In the end, it's up to ANFI to contact professional parachute companies. Although some parachute companies are more flexible, they must have a parachute license, or they must be tied to the coach to jump together. However, Ren He thinks that first, he doesn't need to go to special research, and second, he has money.

In China, a society of human feelings and money, the rich can not let the ghost push the mill.

Ren He believes that in such a big China, he is bound to find a company that can parachute according to his own requirements.

An Si agrees. He has already set out to inspect 23 companies on the list, and will finally choose the most suitable one. Liu Er Bao also plans to start a new shooting.

The deadline is two months. I still have a lot of time to prepare. At this time, Zhang Ming got the script about "Crazy Stone", as well as all kinds of fine human settings and sub lens portraits. The script is very good. Even an experienced and famous director like Zhang Ming will be a little excited when he gets the script. Every character in the script is a small person in the current society. Because of money, fame and wealth and faith, he unfolds a series of black humor stories, which is very interesting. Ren He also has his own suggestions for the actors in the script. For example, roommate Zhang Jinglin can play the international Avenue Mike who plays cool all day long. This guy is usually quiet and his figure is more in line with the script. Besides, Mike's part is not too much, and he can't have any acting skills. It's just suitable for students like Zhang Jinglin to continue to polish their acting skills. Yang Runrun plays Xie Xiaomeng, the son of the boss of the factory. He is a black sheep with a lot of scenes. Although not as fat as the original role, Ren He felt that his acting skills were enough to support the role. Li Shuaizhen and Ren He hope that he can make another breakthrough in the original superb acting skills, and play the ruthless boss played by Xu Zheng. Zhang Ming thinks there is no problem with these suggestions, because to be honest, these roles belong to the category of supporting roles. An investor only requires to arrange such a few actors, and they all have their own acting skills, which is nothing.
