Now that the difficulties were listed, the next step was to solve the problem.
It seemed like the lithium-ion polymer battery was the best solution for the endurance problem. Since the drone was for military use, there might not be time to charge it. Therefore, the battery compartment was designed to be quickly replaceable. When necessary, fuel cells could be used.
The battery could be customized after the design of the three drone shells was completed. Then, the university would contact the New Energy Research Institute to customize the battery compartment.
The problem of control was a big problem for Qu Sen and the other two. However, the school they were in specialized in teaching information engineering. Wireless technology was an important part of information engineering, so there was no shortage of talents in the school.
Professor Wu, who often came to watch the progress of the drone, was a professional. The three of them could rely on him, so the control distance was not a problem.
The last problem was the Hummingbird's silence problem and Qin Nu's image capturing problem.
The difficulty in the silent design mainly came from the noise of the propeller blades and the drive motor. The solution to this problem was thought of by Jiang Mei. That was to find a way to contact the manufacturer of the electric fan.
That's right, the electric fan used to cool down in the summer. This kind of thing was not difficult to manufacture, so there were many domestic manufacturers. The more manufacturers there were, the more intense the competition.
In order to occupy more market share, the competitors sought advantages from price and appearance. On the other hand, they focused on noise control.
After all, when two products with similar price were put together, the brand and quality were similar. When the consumers saw the fan, other than the appearance, they also wanted to see which one had the lowest noise.
Coincidentally, quite a few of the well-known large home appliance manufacturers in the country were military manufacturers. Although these manufacturers had moved, they were still inextricably linked to the military.
After the school helped to contact a well-known manufacturer in the Sichuan region, they happily expressed that whether it was the silent fan blade or the silent motor, they had unique technical reserves.
Also, they had been paying attention to the popular four-propeller drone for a while. Considering that the drone could be used as a toy and a powerful tool, the relevant technical accumulation was underway. They just needed to reduce the production cost and launch the product at the right time.
In response to the demands of the University of Information Engineering, the manufacturer happily expressed that they already had several laboratory samples of the motors and could provide them to the university for free. But in terms of the paddles, because their factory's paddles were produced by other factories, they could only provide the technical specifications.
Because the drone's blade had high requirements for the material, and they needed to contact a professional manufacturer to open the mold, the problem was temporarily put on hold.
Qu Sen and the other two began to focus their attacks on Qin Nu.
Qin Nu's hardware was the best he could find, so if he wanted to solve the image capture problem, he could only work on the software.
In response to this problem, Qu Sen and Li Ying began to search for information on the Internet. Zhou Li, on the other hand, sent the problem back to the School of Wuyi for support.
The problem persisted until after Christmas. Finally, the engineers from Room 4 of No.51 High School came up with a solution. That was to equip Qin Crossbow with two cameras. One was for guiding the flight, and the other was for high-speed capture during the drone's flight.
Finally, a set of connected high-definition images was formed, and the enemy's sniping position was captured from the high-definition images.
This plan was completely feasible, but the high-speed camera needed to have good anti-shake performance if it wanted to take high-definition pictures when the drone was moving quickly.
In order to achieve the expected effect, both software and hardware anti-shake had to be worked on at the same time.
The engineers from Room 4 could help with the software anti-shake, but the hardware anti-shake required more sophisticated gyroscopes and matching drivers.
In addition to the military's software design, the School of Wuyi would also continue to accumulate technology. After the director of Room 2 learned of the situation, he offered to help find a suitable gyroscope and be responsible for the matching driver development.
However, the final ownership of the technical results must be clear.
As for the ownership of the technology, Qu Sen and the other two naturally had no problem at all. They very happily reached a consensus with Office 2. Then, the director of Room 4 also made the same request as the director of Room 2. Then, the software anti-shake problem quickly changed from the engineers' "private work" to Room 4.
Therefore, Qin Nu's technical problem was solved.
After the big problems were solved, it was the end of December. The three suspended the exterior design of the three drone models. Zhou Li and Li Ying began to design the control software. Qu Sen took the time to review and focus on the upcoming final exam.
On the 10th of January, which was the day of the Laba Festival, Qu Sen finally finished the three days of final exams. He once again focused on the drone research. Because Chinese New Year was early, the three discussed and decided to use the time before Chinese New Year to complete the software design.
As for the rest, he could continue after he returned home for the New Year.
When the three of them wrote the control program for Zhou Li's "toys", they already had some technical experience. Although the control platform for the Swift, Hummingbird, and Qin's crossbow was more complicated and more professional, the overall project was still quite smooth.
Because the OMAP1703 chip provided better integration and a rich set of instructions for the drone, in some ways, the control program was easier to create.
The three spent their energy mainly on the various hardware drivers.
When they were busy, it always felt like the days flew by quickly. The three control platforms with their own characteristics were just released and it was close to the end of January.
Li Ying was so busy that she could not wait to call home three times a day to urge her to come back to work until the Lunar New Year. On the 26th, they stepped on the train home. Qu Sen and Zhou Li persevered until the 28th. During the day, the two of them spent most of the afternoon on the streets to buy new clothes and gifts for their families.
In the early morning, they got on the train together and rushed back home before Chinese New Year's Eve.
Qu Sen's mother was very dissatisfied that her son came back so late. She was even more dissatisfied that her son didn't bring Zhou Li back.
The only thing she was satisfied with was the thermal underwear that Zhou Li bought for her and Father Qu.
With the start of the Spring Festival Gala, the Chinese New Year came as promised. When the clock struck midnight, it marked the end of the Year of the Horse and the beginning of the Year of the Sheep.
On the morning of the first day of Chinese New Year, Qu Sen wished his parents a happy Chinese New Year. His parents gave a very formal response. However, when Lady Zhou called to wish them a happy Chinese New Year, the couple's faces almost bloomed with smiles.
After Zhou Li greeted Qu Sen's parents, according to the principle of reciprocity, Qu Sen also greeted Zhou Li's parents, "Happy Chinese New Year."
Perhaps it was because of the Chinese New Year, but Zhou Li's mother's attitude towards Qu Sen over the phone was quite cordial. However, Qu Sen didn't know if it was because of his imagination, but he still felt that the other party's cordial response was filled with a strong sense of distance.
However, Zhou Li's father, whom Qu Sen hadn't met, was very enthusiastic over the phone. He sincerely invited Qu Sen to come over and play when he was free.
When Zhou Li's father sent a second invitation over the phone, Qu Sen heard Zhou Li's mother's voice in the background. "How many days do you stay at home in a year? It's as if you can see people coming. "
When her son first came home, a certain mother showed all kinds of dissatisfaction. However, starting from the third day of Chinese New Year, Qu Sen's mother would drag Qu Sen along with her wherever she went.
At other people's houses, she would listen to friends and relatives saying things like she had a good son with a "humble" face.
Originally, Qu Sen and the other two's plan was to go back to school after the eighth day of Chinese New Year at home to continue the project. However, the three of them encountered strong resistance from their respective families. After communicating over the phone, they reluctantly decided to change the time to the 15th day of Chinese New Year.
Therefore, on the afternoon of the 18th day of Chinese New Year, Qu Sen and Zhou Li took the same train back to school. Li Ying came back almost six hours earlier than Qu Sen and Zhou Li.
