After staying in the laboratory for several days, Wu Hao and Yang Fan have been conducting research on the technology of small high-speed drones for the 'Battlefield Sweeper'.
After unremitting efforts, Yang Fan and the technical research and development team have come up with a small high-speed quadcopter drone with a speed of more than 300 kilometers per hour.
What is the concept of a speed of 300 kilometers per hour? This means that this small quadcopter drone can fly up to five kilometers per minute, which is 83.333 meters per second.
This means that if our combat boots team comes into close contact with enemy troops. If such a high-speed small attack drone is released within a hundred meters, the opponent may only have a reaction range of about one second, and there is no time to evade or intercept it.
Even an agile master can react in this second and find a bunker. This high-speed small attack drone is not a bullet with a fixed trajectory. It will quickly change direction according to the movement of the opponent, thereby choosing the best angle to attack the target, basically not giving the enemy any chance to dodge.
What is the best angle, that is to say, the most reasonable angle. Theoretically, there is no blind spot at 540 degrees. In addition to the ground you are stepping on, attacks may come from other places.
Hand grenades and rifle grenades can also work at the same distance, but they are far less deadly than this thing.
If the combat team has enough of these high-speed small attack drones during close contact, it is theoretically possible to resolve the battle in an instant.
A swarm of high-speed small attack drones took off, flew towards the enemy's position, found the enemy target through the reconnaissance system and then attacked. The whole process can be taken care of by the 'battlefield sweeper system' itself, or manual intervention is possible. This will undoubtedly change the combat rules and forms of close combat, urban street combat, and complex terrain combat in the future.
Of course the idea is wonderful, but the actual development is very difficult. The speed of drones has been improved, and there is even room for improvement.
However, it has encountered very difficult problems in autonomous cruise to avoid obstacles and in intelligently discovering and identifying targets.
The first is how to install a large number of sensors and equipment on a small drone that is only a little larger than an adult's palm and has a very limited payload.
This is like concentrating all the equipment and technology on driverless cars into such a small device, which is undoubtedly a huge problem in terms of hardware integration.
In fact, their autonomous cruise and obstacle avoidance technology is very similar to driverless car technology, but there are also many differences.
First of all, they are all unmanned and autonomous navigation. They not only need to plan the route but also avoid obstacles, and the speed is also very high.
However, the speed of cars is still far inferior to the speed of small high-speed drones like them, and cars actually have routes and only need to perform two-dimensional movements on the road, that is, left and right directions and acceleration and braking.
When a drone flies in the air, its trajectory is three-dimensional. There are various routes and obstacles encountered, which are far more complicated than on the road.
And because of its high speed, it is necessary to quickly locate the detected obstacles and re-plan the route to change the direction, all of which must be responded to within a thousandth of a second or even a ten-thousandth of a second. There are very strict requirements for the hardware itself, including drones, flight control systems, sensors, etc.
In addition, processing system software is also a very troublesome problem. How to quickly process these data in a very short time or process these data in real time is a very big problem for system developers, including Wu Hao.
Because this is a small high-speed attack drone, its payload is actually very limited. In addition to the necessary onboard electronic equipment, it must also carry batteries and ammunition for attack. The amount of powder charged is directly related to the power of your small high-speed attack drone.
Take the grenade, the most commonly used throwing weapon currently used by infantry, as an example. The domestically produced 82-2 all-plastic handleless steel ball grenade weighs 260 grams. Its internal explosive charge is about 60 grams, and the rest of the weight comes from 1,600 steel balls and a plastic injection-molded projectile and detonation device.
You may not have any idea about the weight of 260 grams. If you convert it, it is about half a catty.
Although there is no need for so many steel balls and a full plastic shell on the drone, the fragments produced by the drone itself after the explosion are good fragments and are highly lethal. And in the future development process, the materials and designs of the drone fuselage will move closer to this aspect.
On the one hand, it is to increase the fragmentation power, and on the other hand, it is to protect the technical secrets of this drone.
But for such a small drone, every gram of weight on it is precious, and there is no luxury.
The speed of a drone is inversely proportional to its own weight. The heavier the weight, the slower the speed of the drone. Therefore, in order to maintain a high speed, the weight of the drone must be strictly controlled within the allowable range.
This requires that the drone must be as light as possible, or the power of the drone must be increased as much as possible. When there is not much improvement in power, your own weight becomes the best choice.
Under the condition of being extremely light, it is required that the airborne equipment, batteries, and ammunition must be reduced as much as possible to meet its speed.
Not much to say about batteries and ammunition, they are a must. In order to ensure its power and range, or its endurance in the air, it must be at a certain weight.
Therefore, in addition to improving the power performance and increasing the load, what can be deducted can only start from the equipment it is equipped with.
Therefore, the equipment that can be carried on such a small drone is actually very limited.
Small equipment means that its power is small, which will not only affect the UAV's data processing capabilities, but also affect the UAV's detection range of surrounding obstacles.
You know, within the limited weight, these sensors must be made small enough. This means that its power will be smaller, so the distance it can detect will be greatly reduced.
The speed of drones is very fast and the detection distance is small, so the time left for drones to process and respond is very limited, even only a few milliseconds or even microseconds.
This not only requires the sensor to have a fast response time, but also requires the system on the drone to be able to process this information in the shortest time and control the drone to quickly maneuver and change direction.
The entire drone must be perfectly integrated from hardware to system to sub-control without any hesitation.
Otherwise, for a drone that crosses obstacles at high speed, it will be an infinite crash.
