Why is a drone called drone?

The reason why the man-machine is called "drone" is related to a number of aspects:

I. History and Origin
"Drone" originally referred to drones in English, especially drones that do not participate in honey harvesting. These drones play a passive role in the bee colony, with the main task of mating with the queen bee and dying soon afterward.
In the early days of drone development, people began to use the word "drone" to describe these aircraft because they were also designed and remotely controlled by humans to perform specific tasks without the need for direct pilot control like manned aircraft.
2. Sound characteristics
When a drone is flying, its propellers or engines tend to emit a low, monotonous humming sound that is quite similar to the buzz that drones make when flying. Therefore, the word "drone" is also associated with drones because of its sound characteristics.
3. Functional similarity
Drones and drones also have certain similarities in functionality. Drones are mainly responsible for mating tasks in a bee colony, while drones are aircraft designed by humans to perform specific tasks, such as reconnaissance, filming, logistics, etc. Although their tasks are very different in nature, they have something in common when it comes to "unmanned operation" and "performing a specific task".
Fourth, wide application and acceptance
With the continuous development of UAV technology, its application in military, civilian and other fields is becoming more and more extensive. The word "drone" was gradually accepted as a synonym for drones, and it is still used today.
To sum up, the reason why "drone" has become a common name for drones is because the word is associated with drones in several ways. It is not only similar to drones in terms of sound characteristics, but also has certain commonalities with drones in terms of function, and also has a deep historical background.
