UAV: A non-manned aircraft operated by a radio remote control device and a self-contained program control device, or operated autonomously by the onboard computer completely or intermittently; referred to as UAV for short.
Model: It is an air-heavy, size-limited aircraft with or without an engine that cannot carry people.
Aircraft model: A model that is scaled down by a certain scale of the aircraft and cannot fly.
Model aircraft: A toy that can fly and can control the aircraft by remote control.
UAV composition: At present, we can regard the whole UAV system as composed of multiple subsystems. The whole UAV system includes navigation and control system, link system, ground station system, power system and mission load system. And the body platform
1, by power
According to different power sources, drones can be divided into oil and electric. As the name suggests, the oil-powered drone uses fuel (gasoline) as the drive, and the electric drone uses the battery (lithium battery) as the drive. The obvious advantage of the oil-powered drone is that it has a long battery life, but there are safety hazards, and the crash may cause a fire. The electric drone is much safer, but it is limited by the battery and has a short battery life.
2, according to the appearance structure
According to the appearance of the drone, we can roughly divide them into three types of drones: fixed-wing, helicopter, and multi-rotor. Due to their different structures, they also have their own characteristics.
Advantages: long battery life and large load
Disadvantages: take-off must run, landing, taxiing, non-stop hovering
Helicopter Advantages: vertical takeoff and landing, fixed point hover
Disadvantages: complex structure and difficult maintenance
Multi-rotor Advantages: vertical take-off and landing, fixed-point hover, simple structure
Disadvantages: short battery life, low load, high flight control requirements
