what are drones

A drone is an aircraft that has no human pilot on board, so they are also called UAVs or unmanned aerial vehicles. Drones are either by default or have remote control for flight. When you use two-person terms such as UAS (meaning unmanned aerial vehicle system), RPAS (meaning long-range air system) or SUAS (meaning small unmanned aerial vehicle) Aircraft system), they are using military terms that describe specific types of drones.

There are different types of drones on the market for recreational and professional purposes. Drones are classified according to four factors.

#1. Multi-rotor Drones

Multi-rotor drones are the most common in these days, they are easiest to use, and the cheapest type of drones available on the market. Multi-rotor drones are classified by the number of rotors: tri copter (three rotors), quad copter (four rotors), hexa copter (six rotors), and octo copter (eight rotors).

The significant downsides of multi-rotor drones that have limited endurance, limited flying time, and limited speed. Multi-rotor drones can fly for only 20-30 minutes with a small payload such as a small camera. Their uses include:

#2. Single-rotor Drones

Single rotor drones are like a mini helicopters. In the same router drone, a large router and a small router are attached to the tail to control its heading. Single rotor drones carry very long blades that enhance their performance with multi rotor drones.In aerodynamics,  the larger the rotor blade, the slower its speed and the higher its efficiency.


Single-rotor drones have the advantage of greater performance than multi-rotor drones and are even more tolerant as they can be gas-powered, which increases flight time. The downside of single-rotor drones is that they are more complex to use, more expensive, and more dangerous because of their larger blades. They are not as stable as multi-router drones. They are usually good for purposes such as:

#3. Fixed-wing Drones

Fixed-wing drones use the aerodynamic principles of aircraft. They use wings in lifting, unlike single and multi-rotor drones that rise vertically. The default wing drones provide high efficiency, long travel distance, and long flight duration. When they are gas-powered, they can fly for 16 hours or more.

The biggest drawback of fixed-wing drones is that they cannot be in one place. This makes launching and landing very difficult. You will need a runway or catapult launcher for takeoff and a runway, parachute, or safety net for landing. However, the smallest fixed-wing drones can be suitable for hand launches and “belly landings” in any open space. They are commonly used for:

#4. Fixed-wing Hybrid VTOL

The Fixed Wing Hybrid is an integration of the advantages of the Fixed Wing Drone, which has the rotating capability of rotary-winged drones that enable it to land and land vertically.

They are commonly used for:
