Qu Sen and the other two were happy enough to get the official approval from the school. They didn't have time to think about money.
Professor Wu naturally approved of his two students participating in the general assembly organization's recruitment activities. He was also very optimistic about the possible use of small drones in the military.
The two master's students had no problem, but Qu Sen had a problem. He still had five professional courses to pass at the end of the semester. Qu Sen used the approval from the school's leaders as an endorsement. He even pulled Professor Wu out. After promising countless times to the tutor, Jiang Mei, that the exam would not be delayed, they finally got the approval.
As soon as the formal design began, the three of them encountered the first problem – the control chip of the drone.
The three drones that were going to participate in the competition were all for paramilitary purposes. Whether it was function expansion or data interaction, they all needed professional control chips to meet the expected design requirements.
Although the "toy" that the three modified Zhou Li's drone was also equipped with video and audio signal acquisition and transmission, it was only on the basis of the original functions of the drone. The two components with wireless signal transmission functions were integrated.
When the drone flew, the remote control, video, and audio signals actually worked separately. They were operated together through the production control software.
This kind of thing was okay for fun. If it was really used for military purposes, not to mention the anti-interference ability and real-time transmission speed, the energy consumption was a big problem that couldn't be overcome.
In order to solve these problems, and at the same time add more functions to the drone, they would need to provide a variety of professional control chips to carry out the main control calculation.
After realizing that with the current ability of the three of them, it was impossible to get a professional control chip, Zhou Li's first thought was to ask her mother for help.
Zhou Li's mother naturally supported her daughter's research with both hands and feet. In fact, the country had already developed a main control chip that was mainly suitable for UAVs. However, that thing, aside from the sexual aspect, was not something that normal military school students could come into contact with due to the level of secrecy involved.
However, Zhou Li's mother still gave an option. Texas Instruments developed a high-performance, high-integration embedded processor for mobile multimedia information processing and wireless communication applications.
At the beginning of this year, the company produced a batch of OMAP17 series of open multimedia application platform chips on a small scale. This chip was designed to meet the needs of mobile multimedia information processing, which was for mobile phones.
Not long after the chip began to be produced, it was discovered that there were many problems with practical applications, and production was quickly halted. Later, our country bought (obtained) all of them through some special channels.
Don't think that these chips are useless just because they have problems. The so-called defects are only problems that exist when applied to the phone's processor. As an open multimedia application platform chip, it still had many redeeming qualities in other aspects, not to mention the technology involved.
Although the relevant technologies are protected by patents, it doesn't affect our research and absorption.
Our country brought back a bunch of 'waste products', and we don't have a production line. Apart from some of them being used for research, the rest are basically useless.
After Zhou Li's mother's evaluation from a technical point of view, this chip could be used as the main control chip of a multi-function drone. His daughter was also using it to create a product for the competition. A few pieces were enough.
Of course, it was impossible for Zhou Li's mother to apply for the chip in the name of her unit for her daughter to use. Qu Sen and the others couldn't apply in their own names, so they could only ask the Information Engineering University.
Since the school leaders had already approved the applications of several students, there was no problem in applying for a few chips in the name of the school. After the report was submitted, it was quickly approved. A week later, five pieces of OMAP1703 chips were sent to the school through the military's confidential express mail.
Qu Sen, Zhou Li, and Li Ying faced five chips that they had never touched before. With the thick and detailed introduction sent with the chips, it took almost a month for Qu Sen, Zhou Li, and Li Ying to study their various performance parameters.
After they figured it out, the three of them couldn't be described as excited. From the performance of this chip alone, it was a luxury to use it to control drones.

With the control chip, the design of the three planned drones could finally enter the practical operation stage.
With the outline of the preliminary design, the high-definition zoom camera, thermal lens, and a series of required components applied by the three of them were also in place.
As these components were tested in the laboratory with the 1703 chip, the original design plan was gradually being perfected.
At the beginning of December, the first engineering aircraft without an outer shell was successfully tested.
Although this engineering drone was still far from the final design plan, it proved that with the support of the 1703 chip, the expected functions of the three drones could be fully realized.
The University of Information Engineering had only been established for a few years after the merger. Compared to other universities in the military, it was still a "little brother". The school leaders urgently needed results to accumulate capital for the school.
The so-called capital could be the nurturing of more outstanding graduates, the research results of the professors, and of course, it could also be the ranking of the students in the military competitions, especially the large-scale and high-tech competitions.
If the three students could stand out in the military "drone design proposal collection", it was exactly the result that the school wanted to see.
Therefore, after the engineering drone was demonstrated, the school leaders were amazed by the three students' imagination and execution ability. They were very optimistic about their proposal. There was no need to apply at all. They happily approved a 200,000 yuan research funding.
The principal personally encouraged the three of them and told them not to be afraid of difficulties. If they needed anything, they could ask the school. If the school could solve the problem, they would immediately solve it. Even if they couldn't, they would help contact the military research institutes and factories to find a way to solve the problem.
There was only one goal, which was to demonstrate the quality of the students at the University of Information Engineering in the official selection in April next year.
With the support of the school, Qu Sen and the other two students' enthusiasm reached an unprecedented level.
After passing the engineering tests and confirming the possibilities of the three types of drones in the design, the two girls got together and discussed for a long time before naming the three types of drones.
The first model was equipped with a thermal lens and was mainly used for small area reconnaissance. It was named Swift. The second model was mainly used for covert reconnaissance. It was named Hummingbird. As for the third model, which was used for battlefield surveillance and anti-sniping, Qu Sen finally got the right to name it after an uncompromising fight.
Originally, he wanted to name it Hawkeye, but he didn't think there was anything special about it. Later, he remembered that in his original design, he also wanted to add a combat department to the drone. However, the school didn't allow him to touch dangerous explosives, so he could only keep the idea on the design level.
Although it was only on the design level, once this plan was adopted by the final assembly, there was a high chance that the combat department could be realized.
In the end, Qu Sen named the drone – Qin Crossbow.
After the component problems of the three drones were solved, although it sounded like the rest of the work was not difficult, in fact, they all had their own difficulties.
The biggest problem the Swifts faced was their endurance and the distance they could control. On top of the two problems the Hummingbird faced with the Swifts, they also had to consider their size and the most important issue of silence.
Qin Crossbow expected that as long as it was equipped with a high-definition zoom camera, it wouldn't be a big problem. However, in a real battle environment, the drone didn't have the ability to hover or cruise at low speed to capture the target.
