But this time, they are not making a remote-controlled plane. Instead, they plan to take a different approach and start from the power of the plane to actually make a small, flying plane.
But it was this power problem that stumped the two men. They thought of many methods and tried many different aircraft to assist, but to no avail.
After all, this is not a real plane, and the aviation kerosene used by real planes cannot be used on this small plane.
Their work in the last rematch was a small self-propelled aircraft that could fly without electricity, but the flight time was too short, so it could only be considered a more sophisticated toy.
What the two wanted to make was a small plane that could fly for a long time without any external force.
But after thinking hard for a long time, the two still failed to solve the problem, so they could only pin their hopes on Ji Yue.
The two of them had been harassing Ji Yue, trying to get him to come up with a solution, but suddenly, Ji Yue had no choice, so Chen Mu and An Huai wanted to drag him to study together.
Ji Yue was not very interested in this, so he kept trying to get away.
Su Qingyun listened to Chen Mu and the others' aircraft design concepts without saying anything.
Seeing her expressionless face, Chen Mu felt a little uneasy. He asked cautiously, "You don't think we're just daydreaming, do you?"
"That's not the case." Su Qingyun smiled and shook his head. "Your ideas are very good, and the design is very interesting."
To be honest, in this era, it is rare to see such vigorous imagination and excellent thinking ability. They are talented and dare to think and act, which is already better than most people.
As long as they are trained well, the future of these two people will be limitless.
Su Qingyun didn't want to give them a perfunctory response. She thought about it carefully and said, "Your idea is good, but actually making a small aircraft capable of long-term flight is too complicated."
The expressions of Chen Mu and An Huai both darkened. They knew that their idea was too bold, but this was what they dreamed of creating.
"We will continue to find a way." It was An Huai who spoke. He looked determined and did not back down.
Su Qingyun smiled again. This is the spiritual quality that scientific researchers need to possess. These two people have it, so they will definitely succeed in the future.
"I haven't finished speaking yet."
Su Qingyun continued: "Have you ever played with a bamboo dragonfly?"
"Of course we have." The two nodded affirmatively.
Nowadays, there is a lack of entertainment activities. Whether in the city or in the countryside, the things children play with are similar. Bamboo dragonflies are definitely an indispensable part of everyone's childhood memories.
"The reason a bamboo dragonfly can fly is because the rubbing of your hands gives it a rotational speed, which generates lift, and lift is the driving force that allows the bamboo dragonfly to take off."
"So the rotors of our helicopters are similar to those of bamboo helicopters, right?"
"Why are you so obsessed with making a smaller version of a large airplane instead of a micro version of a helicopter? That's something that's much easier to achieve."
Su Qingyun asked the two of them with a smile, and Chen Mu and An Huai were stunned.
The miniature version of the helicopter she was talking about was actually the drone of later generations.
There is a motor inside the drone. When the motor rotates, the propeller generates lift, which makes the drone take off.
She said these words to point them in another direction.
Chen Mu thought for a moment and asked, "What use is this miniature helicopter you mentioned?"
When Su Qingyun heard this question, many things flashed through his mind.
In later generations, drones are generally divided into military drones and civilian drones. Civilian drones can be further divided into consumer grade and industrial grade. Consumer grade drones are mostly used by photography enthusiasts for aerial photography, while industrial grade drones are generally used in meteorology, agriculture, scientific exploration, security communications, etc.
Military drones can be divided into single-purpose and multi-purpose types. Single-purpose types include unmanned reconnaissance, unmanned combat, communication disruption, and electronic jamming. Multi-purpose types refer to reconnaissance and strike drones.
It can be said that drones have been used in all aspects of life and are extremely useful.
But even after thinking of this, Su Qingyun said nothing. What she had in her mind was just some information from later generations, which would be very difficult to actually realize.
There was no need for her to draw a beautiful blueprint for the two of them now. She only needed to point them in a direction, and the rest was up to her own efforts.
"You have to ask yourself, how far can you go?" She simply said this.
Chen Mu was stunned, as if he didn't expect to get such an answer.
But he still nodded and said thank you sincerely.
An Huai also thanked him sincerely.
