v10 Chapter 3422： Zhao Yus whimsy (1/2)

Of course, Qin Luo did not sit idle while Marco was preparing for the ”stealing of secrets” plan.

After two full days of hard work, a brand-new design drawing was placed before Qin Luo's eyes.

The main structure is prescribed by Qin Luo, and it is still round!

But in the center of the parachute, a hole was added, and ear wing devices were added on both sides.

”Zhao Yu, what's the matter with the hole in the middle?” Qin Luo frowned slightly and looked at Zhao Yu with some confusion.

To be honest, in Qin Luo's impression, none of the parachutes had holes.

Although Qin Luo is not very proficient in aerodynamics, he also has a basic understanding that once the parachute has holes, it will accelerate the flow of air and reduce air resistance.

He really didn't understand what Zhao Yu was thinking.

Didn't sleep for two days, just came up with such a thing?

One thing to say, Qin Luo felt that after two days of nights, they had all stayed on the dog.

”Professor Qin, I call this hole an orifice. The size of the orifice is determined according to needs. Generally, the larger the umbrella area, the larger the diameter of the orifice. His role is also very simple. , Is to make the air form a passage from bottom to top when the umbrella is falling, so that the umbrella remains stable during the descending process.” Zhao Yu said with a smile.

The circular umbrella is very unstable, and the influence of hand air is great.

In order to solve this problem, Zhao Yu consulted countless materials, and finally he found a solution.

Make a small hole in the center of the parachute!

Stroke path to improve the stability of the parachute!

stable?

Qin Luo's mouth twitched. At this moment, he didn't know what to say!

Yes, he first proposed stability to ensure the safety of landing and the lives of astronauts as much as possible.

However, he never said that he made a hole in a parachute!

Stability is important, but the resistance of the parachute is also important.
