Drones - Unmanned Aerial Vehicles

Unmanned Aerial Vehicles (UAV) popularly known as drones that were originally designed for military and aerospace industries have come a long way and have found applications across various sectors like agriculture, infrastructure, transport and delivery, media, telecommunication, security, etc. The enhanced level of safety and efficiency that they offer are leaving a positive impact on market growth. Adding to this, various technologies like RADAR/LiDar, wireless communication, GNSS, satellite communications, and GPS are contributing their bit to make drones all the more popular. Airbus S.A.S, DJI, 3DR, YUNEEC, Kespry, EHANG, Boeing, Delair, AguaDrone, Autel Robotics USA, etc. are some of the companies that are manufacturing UAVs.

Drones

The drone market is gaining traction at a high pace. In the year 2018, the global commercial drones market was valued at about $3.45 billion and is expected to grow to $7.13 billion at a CAGR of 19.9% through 2022. However, due to the economic slowdown across the countries owing to the COVID-19 outbreak, there has been a decline in the growth rate of the global commercial drones market. There are hopes that the growth in market size will be about $6.15 billion in 2023 at CAGR of 19.09%.

The different levels of autonomy and capability of traveling at varying heights and distances are what make one drone different from the other. Talking about the level of autonomy, there are remotely piloted drones with human beings controlling the movements. Besides, there are drones with advanced autonomy (with a system of sensors and LIDAR detectors that help in calculating the movement). Also, different drones are capable of traveling at different heights and distances. These can be categorized as:

  • Very close-range drones that travel up to three miles.
  • Close-range drones that can travel within the range of around 30 miles.
  • Short-range drones that can travel up to 90 miles
  • Mid-range drones that can travel 400-miles
  • Longest-range drones that can go beyond the 400-mile range and up to 3,000 feet in the air. These drones are also known as endurance drones.

With the ability to cover varying distances and go up to different heights, these remotely controlled UAVs are proving to be quite helpful in the surveillance of disaster sites and areas with biological hazards, searching survivors after a hurricane, advancing scientific research in extreme climate conditions, in epidemiology for research and tracking disease spread and likewise. Recently, we witnessed the locust attack in various parts of the country, and drones are being used in different cities for spraying the insecticides to combat the situation. Let’s take a closer look at the different types of drones.

Types of Drones

There are several ways in which drones can be categorized, first one being the usage/purpose (commercial or recreational purposes). Broadly the drones are divided into four categories viz. single-rotor drones, multi-rotor drones, fixed-wing drones, fixed-wing hybrid drones. Other than these, there are small drones, micro drones, tactical drones, large combat drones, target and decoy drones, reconnaissance drones, non-combat large drones racing drones, photography drones, GPS drones, etc. Here’ we are going to discuss some of the drones along with their applications.

Drones

Recreational drones that are also called mini/micro drones are used for just recreational purposes. They are not much expensive and come in the price range of $30-$150. Also, some drones are used by photographers for their high-quality professional work. These drones are a bit expensive and range somewhere between $500 and $2,000. Commercial drones are used for aerial shots for tasks like real estate marketing, collecting data for insurance-related inspections, etc. These drones vary in price range depending upon the tasks for which these are designed (like aerial photography, high-quality aerial photography, television, and movie production, mapping, and surveying). They start somewhere from $ 300 and go up to $25000.

Other than these, the drones can be classified based on their design (multi-rotor drones, fixed-wing drones). Listed below are four types of drones based on their design.

Types of Drones

Single-Rotor Drones:

Single-rotor drones are the basic type of drones that have just one rotor and a tail unit in some cases. These types of drones can generate thrust more efficiently than multi-rotor drones ensuring longer flight times. These types of drones work on the rule of aerodynamics i.e. larger the rotor blade is and the slower it spins, the more efficient it is. The single-rotor drones are costlier than the other types of drones. Besides, the larger rotor blades make these drones difficult to manage and there are chances of accidental injuries. Moreover, these types of drones are often not stable and are difficult to fly as compared to multiple rotor drones that fly in a balanced and stable manner. The price range of these drones is around $25k to $300k.

Multi-Rotor Drones:

A multi-rotor drone is a rotorcraft that has more than two lift-generating rotors positioned at strategic points on the craft. Unlike single and double rotor helicopters that use complex variable pitch rotors for flight stability and control, multi-rotor drones use fixed-pitch blades that make it easier for it to maintain its balance and keep hovering. By varying the relative speed of each rotor, the thrust and torque produced can be changed, thereby controlling vehicle motion.

Multi-Rotor Drones

These drones are perfect for aerial photography as these give great control over position and framing. More the rotors that a drone has, the lesser will be the time it will be able to remain airborne. Offering good stability, the multi-rotors are capable of flying for half an hour. The disadvantage of multi-rotor drones is that these cannot carry a heavy payload and the balance is disrupted if done so. Besides, they have limited endurance and speed, which makes them unsuitable for large scale aerial mapping. Also, to fight gravity and keep flying in the air, it takes a lot of energy. Freefly Alta 8, U49WF FPV Camera DroneYuneec H520, DJI Inspire 2, etc. are the drones that fall into this category. There is a variety of options available with prices ranging from around $5k to $65k.

Fixed-Wing Drones:

As the name hints, these are drones that have fixed-wings and there are no rotors. These look all the more similar to controllable airplanes and not helicopter-style drones. These types of drones are ideal for long-range flights. Their wings provide vertical lift and they just need the energy to keep moving forward. Some fixed-wing drones are gas-powered and are capable of staying in the air for as long as 16 hours.

Fixed-Wing Drones

The major drawback is that these drones cannot hover in the air like the other type of helicopter-style drones. As there is no rotor, these types of drones are difficult to land. Zipline is a medical drone delivery company that is using a fixed-wing drone for delivering blood and other medical supplies to remote areas. senseFly eBee Classic, Parrot Disco, Hubsan Spy Hawk, etc. are some of the fixed-wing drones. The price range of these drones is somewhere from $25k to $120k. The price tag these drones come with is another major drawback and the other one being the level of difficulty one faces to operate them.

Fixed-Wing Hybrid VTOL:

These types of drones have a couple of rotors attached to the ends of fixed wings. The fixed-wing hybrid drones look like aircraft from the 60s. These not available commercially but several companies are working on developing them so we can expect to see them flying anytime soon Amazon’s Prime Air delivery drone is one of the finest example of this type of drone. LP INFORMATION recently released a research report on the hybrid VTOL fixed-wing UAV market analysis, according to which global hybrid VTOL fixed-wing UAV market expected to witness sustainable growth over 2025. Hitec, Ukrspecsystems, Vertical Technologies, DG Intelligent, Threod Systems, Jd.Com Inc, Lockheed, and Martin Corporation are some of the companies that are manufacturing hybrid VTOL fixed-wing UAV. These drones are being used as taxi drone prototypes in Dubai.
