All About Drones and UAVs- For Research Purpose

WHAT ARE DRONES?

Drones are flying robots that can be controlled through software with the help of sensors and GPS. These can be controlled remotely and autonomously. 

More formally, drones are referred to as UAVs that is an unmanned aerial vehicle. Now, these three words are sufficient to define a drone. Unmanned which means that there is no person inside the drone, aerial means it flies in the air and it's a vehicle. 

TYPES OF DRONES

1. Single-Rotor Drones

2. Multi-Rotor Drones

3. Fixed-Wing Drones

4. Fixed-Wing Hybrid Drones

5. Micro Drones

6. Tactical Drones

7. Reconnaissance Drones

8. Combat Drones

9. Target and Decoy Drones

1. Single Rotor Drones- A single-rotor drone has one rotor along with a tail to support its flight. It has a better efficiency over multirotor drones. 

                                     

Note: It is a general rule of aerodynamics that the larger the rotor blade is and the slower it spins, the more efficient it is.

If you need to hover with a heavy payload (e.g. an aerial LIDAR laser scanner) or have a mixture of hovering with long endurance or fast forward flight, then a single-rotor heli is really your best bet.

But they seriously cause large damage to the obstacles. 

2. Multi-Rotor Drones- As the name suggests, these drones have multiple rotor blades which help in maintaining a good balance and stability. 

They don't cause large damage, unlike single rotor drones. Multi-rotors are fundamentally very inefficient and require a lot of energy just to fight gravity and keep them in the air. With current battery technology, they are limited to around 20-30 minutes when carrying a lightweight camera payload. 

3. Fixed Wing Drones- They have nonrotational wings. They can carry heavy payloads for longer distances and have a long flight time.

This makes them well-suited for long-distance missions, such as mapping, surveillance, and defense, where long-endurance can be an important factor.

4. Fixed Wing Hybrid Drones-

they combine the benefit of multi-rotor and fixed-wing drones. The highly suitable to take off and land without any runaway or launcher

5. Micro Drones- They are called spy drones. They are used for spying on the enemies.

 They take different shapes and visualizations like a butterfly, mosquito, etc. They are really Tiny that sometimes it becomes difficult to see them with the naked eyes. 

6. Tactical Drones- They are trained for public safety and other military operations. 

They are highly complex and need a lot of time to train them. They have a special antenna system for ground communication. We will discuss them in detail later on. 

7. Reconnaissance Drones - They have a slightly large size than the commonly used UAVs. These drones are among the most commonly employed by militaries around the world. 

Reconnaissance is a mission to obtain information by visual observation or other detection methods, about the activities and resources of an enemy. And the drones used for them are called Reconnaissance Drones.

8. Combat Drones- Fighter drones are called combat drones. They are significantly used in wars and strikes and carry missiles, ATGMs, and/or bombs

Some of the famous Combat drones are Predator C Avenger, Heron TP, MQ-9B SkyGuardian 

9. Target and Decoy Drones- 

they are used for training anti- crafts. Some of the Target Drones are DRDO Abhyas, DRDO Fluffy, DRDO Lakshya, DRDO Ulka

10. Research and Development Drones-

This type of UAVs are mostly used for conducting research with a specific purpose, especially to develop further drone technologies to be integrated into other UAVs
