Chapter 132: The big problem above the small body

After staying in the laboratory for several days, Wu Hao and Yang Fan have been researching and researching on the small-scale high-speed drone technology of the 'battle sweeper'.

After previous unremitting efforts, Yang Fan and the technical research and development team have come up with a small high-speed four-rotor drone with a speed of more than 300 kilometers per hour.

What is the concept of 300 kilometers per hour, which means that this small quad-rotor drone can fly at a distance of 5 kilometers per minute and 83.333 meters per second.

This means that if our combat boots squad are in close contact with enemy forces. When this high-speed small attack drone is released within one hundred meters, the opponent may only have a reaction distance of about one second, which is too late to evade or intercept.

Even an agile master, when he reacted and found a cover in this second. 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, so that it will choose the best angle to attack the target, and basically will not give the enemy any chance to dodge.

What is the best angle, that is, the most reasonable angle. In theory, there is no dead end at 540 degrees. Other than the land on which you are stepping, other places are likely to strike.

Grenades and grenades can work for the same distance, but far less deadly than this.

If the combat team has enough such high-speed small attack drones during close contact, theoretically it is likely that the battle will be resolved in an instant.

The cluster of high-speed small attack drones took off, flew towards enemy positions, searched for enemy targets through the surveillance system, and attacked. The entire process can be handled by the 'Battlefield Sweeper System' itself, or it can be intervened manually. This can undoubtedly change the rules and forms of combat in future close range operations, urban street battles, and complex terrain operations.

Of course the idea is beautiful, but the real research and development is difficult. The speed of drones has improved, and there is even room for improvement.

However, it encounters very difficult problems in avoiding obstacles on automatic cruise and intelligently identifying and identifying targets.

The first is how to solve this large pile of sensors and equipment installed on a small drone that is only a little larger than an adult's palm and has a very limited load.

This is like concentrating all the equipment and technology on the driverless car on such a small device. It is undoubtedly a huge problem for hardware integration.

In fact, their automatic cruise avoidance technology is similar to driverless car technology, but there are many differences.

The first is unmanned control and automatic navigation, not only to plan routes but to avoid obstacles, and the speed is very high.

However, the speed of cars is still far less than the speed of their small high-speed drones, and the cars actually have routes, and only need to perform two-dimensional plane movement on the road, that is, left and right directions and acceleration braking.

While the drone is flying in the air, its movement trajectory is three-dimensional. The routes are diverse and the obstacles encountered are far more complicated than on the road.

And because of the fast speed, it is necessary to quickly locate the obstacles and re-plan the route and change the direction, all of which must react within a thousandth of a second or even a thousandth of a second. Regardless of the hardware itself, including drones, flight control systems, sensors, etc., there are very strict requirements.

In addition, processing system software is also a very difficult problem. How to process these data quickly or in real time in a very short period of time is a very difficult 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 on-board electronic equipment, it also needs to carry batteries and ammunition for attack. The amount of charge is directly related to the power of your small high-speed attack drone.

Taking the most commonly used throwing weapon grenade for infantry as an example, the domestically produced 82-2 type all-plastic handleless steel ball grenade weighs 260 grams. Its internal charge is about 60 grams, and the rest of the weight comes from 1600 steel **** and plastic injection-molded bodies and detonation devices.

For the weight of 260 grams, you may not have any concept, and the conversion is about half a catty.

Although so many steel **** and all-plastic shells are not needed on the drone, the debris generated by the drone itself after the explosion is a good fragment, which is highly lethal. And in the future development process, the materials of the drone body, including the design, will move closer to this aspect.

On the one hand, it is to increase the power of fragmentation, and on the other hand, it is also to protect the technical secrets of this drone.

But for such a small drone, every gram of weight above is very precious and not rich.

The speed of the drone is inversely related to its own weight. The heavier the weight, the slower the drone's speed. So in order to maintain a high speed, the weight of the drone must be strictly controlled within the allowable range.

This requires drones to be as light as possible, or to increase their power as much as possible. When there is not much improvement in power, its own weight becomes the best choice.

Under the most likely light conditions, it is required that the amount of airborne equipment, batteries, and ammunition must be reduced as much as possible to meet its speed.

There is not much to say about batteries and ammunition, this is a must. In order to ensure its power and range, or lag time, it must be guaranteed at a certain weight.

Therefore, in addition to improving the dynamic performance and increasing the load, it can only be started from the mounted equipment.

Therefore, the equipment that can be carried on such a small drone is actually very limited.

A small device also means that its power is small, which not only affects the drone's ability to process data, but also affects the drone's detection range for surrounding obstacles. UU reading books www.uukanshu.com

Be aware that these sensors must be made small enough within a limited weight. This means that its power will be smaller, so that the distance it detects will be greatly reduced.

The drone is fast and the detection distance is small, so the time left for the drone to deal with it is very limited, even only a few milliseconds or even microseconds.

This not only requires the sensors to have a fast response time, but also requires the system mounted on the drone to process this information in the shortest time and control the drone to change directions quickly.

The entire drone must be perfectly integrated from the hardware to the system and then to the sub-control. There must be no hesitation.

Otherwise, for drones crossing obstacles at high speed, it is an infinite bomber crash.
