When Gu Baozhu saw this, she immediately explained and picked up a modified brushless motor.
"Mr. Hu, this is the motor I modified. As you know, the motor can convert electrical energy into mechanical energy to drive the propeller to rotate, thereby generating thrust.
It's just that our existing brushed motors are relatively inefficient and bulky, so I modified them based on the brushed motors and converted the brushed motors into brushless motors.
The brushless motor is composed of a motor body and a driver. Since the brushless motor operates in an automatic control mode, it does not need to use variable frequency speed regulation. A heavy-load starting motor has a starting winding attached to the rotor and will not oscillate due to sudden changes in load.
Or lose a step..."
"etc!"
Mr. Hu felt that he might be hearing hallucinations, so he quickly interrupted the young comrade's words.
He just heard a young comrade say that he had modified a brush motor into a brushless motor. He must have been hearing hallucinations!
"Mr. Hu, do you have any questions?"
Gu Baozhu looked puzzled. Could it be that there was something wrong with his brushless motor?
"Maybe I didn't hear clearly just now, but you said this is a brushless motor you modified?"
Gu Baozhu nodded, not knowing why, "It's me, is there any problem?"
"No..." Mr. Hu took a deep breath, his breathing a little rapid.
Any questions?
It’s a big problem, let’s get over it!
In less than a day, Comrade Xiao Gu gave himself such a big surprise, which was really scary.
"Are you sure you can use this brushless motor?" Mr. Hu asked uncertainly.
"Of course." Gu Baozhu nodded naturally, otherwise why would she bother to modify it.
Brushless motors have high reliability, no commutation sparks, and low mechanical noise. They are more reliable than brushed motors, which is why she wanted to modify them.
"Mr. Hu, why don't you go aside and take your time? I still have some things on my hands that I haven't finished yet!"
Hu Lao choked, does this little comrade dislike him?
"You're busy, I'm watching from the side."
It can be seen that this little comrade is currently focusing on modifying parts. He is really busy and it seems natural that he dislikes himself.
He looked at the brushless motors. No matter what the result was, it would be better to find someone to keep an eye on them near the laboratory. Who would let this little comrade make a big move?
In just one day, Gu Baozhu completed the production of the body and power system, and the rest was the production of solar panels.
She plans to work overtime and make the solar panels tonight and assemble them directly tomorrow.
As for electric vehicles, it may take a few days.
When he heard that she was going to make solar panels, Mr. Hu couldn't bear it. He asked Li Wei to find someone to keep an eye on the place and not allow anyone to come in or out. This work lasted for several hours.
Looking at the freshly baked solar panels, Mr. Hu was so excited that he almost fainted.
However, Gu Baozhu didn't give him a chance to ask. After all, it was already so late. If he didn't go back, his parents would be worried.
In Mr. Hu's hands, Gu Baozhu turned around and left without any hesitation.
The next day, Gu Baozhu woke up before six o'clock.
After hurriedly dealing with the two of them, they were ready to go out.
Seeing her daughter about to go out again, Zhang Xiuying couldn't help but ask, "Baozhu, what have you been busy with these two days? You went out at dawn and didn't come back until late at night. I see you have lost weight in the past two days."
Gu Baozhu had to comfort her worried mother, "Mom, don't worry, we will be finished in a few days."
Zhang Xiuying sighed after hearing this, "Don't forget, tomorrow..."
"Don't worry, I won't forget it. I'll remember it all."
Gu Baozhu hugged her, then turned and left.
Zhang Xiuying couldn't help but feel sore in her eyes. After today, her daughter is no longer alone.
Now she just hopes that the Song family really loves their daughter, and that will be enough.
Arriving at the laboratory, Gu Baozhu began to assemble the remote control aircraft.
The various parts of the remote control aircraft were either modified by her or made by herself, so it was not too easy to assemble them.
The seven remote control planes only took her less than two hours. Looking at the seven identical planes, Gu Baozhu suddenly felt a sense of pride.
I wonder if the nephews will jump with joy after receiving the gifts.
If time hadn't allowed, she would have wanted to install a camera device on it.
Let’s do this for now, and the remaining functions can be developed slowly later.
The assembly is complete, now all that remains is the test flight.
Because it uses solar cells as the energy source, Gu Baozhu directly carried the plane outside, and then exposed the plane to the sun.
After sunbathing for about half an hour, Gu Baozhu started to control the remote control.
Soon, the small plane began to take off slowly.
Slowly, the plane flew higher and higher. As Gu Baozhu operated, the small plane made various cool movements in the air.
Gu Baozhu was very satisfied with the results of the test flight.
The only dissatisfaction is that the remote control is not very smooth, and there will be occasional pauses. Fortunately, after a pause of one or two seconds, the aircraft will not fall.
Satisfied, Gu Baozhu carried the plane and walked to the laboratory. Before he could reach the laboratory, he was stopped by several old men who hurried over.
"Little comrade, just now, just now..."
"Little comrade, what just flew into the sky?"
"Little comrade, can you show us what you have in your arms?"
"What do you mean?" Gu Baozhu was very generous and directly handed over the plane in his arms.
"This is a remote control airplane I made. It was just tested. Do you want to play with it? I can play with it for you for a while, but you have to give it back to me."
"Just give it to us?" Mr. Wang looked confused.
Is this little comrade too unsuspecting to just give it to them?
Gu Baozhu waved his hand indifferently, "I'm not giving it to you, I'm lending it to you to play with."
She was not a fool. These people looked like they were from the Academy of Sciences, and they looked excited. If she guessed correctly, these people should be on the same level as Mr. Hu. She was very relieved, not to mention her
The sixth sense is always very accurate.
"You guys go ahead and play. I still have things to do. If the plane runs out of power, just put it in the sun. This is the remote control to control it."
"These are the up and down keys, and these are the left and right keys. You can play with it yourself. I'm going back."
It was such a hot day. If it wasn't for the test flight, she wouldn't want to go out to bask in the sun. It was so hot.
"Hey, little girl..."
Before they had time to say anything, they saw the little girl turn around and enter the laboratory building, and then left without looking back.
The three old men who were over fifty years old looked at each other, as if they did not expect such an ending. This little girl must be too worried!
"Mr. Wang, try it quickly."
Didn't they come down just for this small plane? Moreover, this small plane has a body made of aluminum alloy.
This is not the most important thing. The most important thing is that this little plane can really fly, and it is controlled by this gadget.
Mr. Wang carefully placed the plane on the ground and pressed the switch on the remote control.
The next second, the small plane really took off.
Mr. Cheng and Mr. Yang looked at each other and saw the disbelief in each other's eyes.
"It really took off."
"It seems it can be higher." Mr. Cheng looked nervously at the plane in the sky and couldn't help but urge, "Mr. Wang, try how high it can fly."
These people are all big names in all walks of life, and their visions are naturally different. It can be seen at a glance that the technology of this small aircraft is not simple.
Mr. Wang may not dare to operate it at the beginning, but once he becomes familiar with the operation later, he feels more at ease.
The height of the plane also got higher and higher, and finally, it even reached a height where they were almost invisible, let alone one or two thousand meters.
Several people looked a little serious, this was no longer as simple as an ordinary plane.
Mr. Cheng touched his chin and said, "Take the plane back first. If I remember correctly, that little girl should have been brought in by Mr. Hu."
"Let's go and ask Mr. Hu."
Mr. Wang put away the plane, and then the three of them went straight to Mr. Hu's office.
When Mr. Hu came over, she discovered that the young comrade had made another shocking achievement. Is this the gadget she was talking about?
