v10 Chapter 3411： Ear wings (2/2)

”Tell me, why is the square umbrella more accurate than the round umbrella? And it is not affected by the wind direction?” Qin Luo asked.

Yes, why is the square umbrella more accurate than the round umbrella and is not affected by the wind direction?

Qin Luo was really curious.

why?

Zhao Yu was taken aback for a moment, he had never thought that Qin Luo would raise such a question.

Before Qin Luo said that he was not good at aerodynamics, Zhao Yu also felt that Qin Luo was bragging, but now, after Qin Luo's question, he is finally convinced.

Qin Luo is really not familiar with aerodynamics!

Otherwise, he couldn't ask such a question anyway.

”It's very simple, because of the design of the square umbrella.”

”His area is relatively large, and he has added ear wings!” Zhao Yu said.

Ear wings?

Hearing this word, Qin Luo's eyes suddenly narrowed, this word is quite strange.

”What is the ear wing? Tell me carefully.” Qin Luo asked.

”In fact, it's nothing, similar to a dog-skin hat with ears on both sides.” Zhao Yu said with a smile: ”This thing can keep warm when worn on the head.”

”But when used on a parachute, you can better control the direction.”

Ear wings!

Qin Luo silently remembered in his heart, he had a kind of intuition, this thing is likely to be the key to solving the problem!

Controlling direction, in other words, is to reduce the impact of risks on parachutes!

Well, this is a good cut!

After thinking for a while, Qin Luo picked up paper and pen and threw himself into the design of the parachute.

Although he is not professional, it does not hinder his whimsy!

At the Yanjing Aerospace Technology R&D Center, Yin Guodong kicked the phone back into his trouser pocket.

Just now, he sent it to Nasa's phone.

On the phone, the other party confirmed the time to go to the United States, and the words insinuately asked Qin Luo for information.
