Introduction
Unmanned aerial vehicles (UAVs) are usually referred to as "drones."These UAVs are capable of flying in the same ways that conventional aircraft (aeroplanes flown by pilots) are.Drones, unlike airplanes, do not always need a human pilot (the Autopilot mode is similar).The industry calls an unmanned aerial vehicle's space position a "Platform".The term "Payload."refers to the hardware or embedded systems.Attaching payloads to drone platforms expands their uses and improves their performance [1][2][3].As the name indicates they eliminate the operators from the boards and permit new mode of exercises.However, Ballistic, cruise and artillery missiles, torpedoes and satellites vehicles with similar characteristics cannot be considered as drones [4,37,38].The technology advancement aspects with fabrication, celestial navigation, higher bandwidth, remote control capabilities and power backup makes easy accessibility of drone where human presence is terrible or hazardous [5,6].
Basically Drones can be classified on the basis of different platform, mission and parameters.Researcher classified the drones' based upon characteristics, such as size, flight endurance, and capabilities.In their drones' classifications, they classified them as MAVs (Micro or Miniature Air Vehicles), NAVs (Nano Air Vehicles), VTOL (Vertical Take-Off & Landing) and drones on the bases of altitude and endurance like LASE (Low Altitude, Short-Endurance), LALE (Low Altitude, Long Endurance), MALE (Medium Altitude, Long Endurance), and HALE (High Altitude, Long Endurance) [7].Researchers classified drones on the basis of weight as nano, micro, mini, small, tactical, HALE/MALE/strike drones [8][9][10][11].Investigator suggested drones classification based on their flying range also [12][13][14].A similar study identified six subcategories: near range, short range, medium range, long range, endurance, and medium altitude long endurance [15,16].Operational purpose, fabrication material, complexity, and control system cost can also categorise drones [16].Today, technology drives researchers to create UAVs for vertical takeoff, landing, and hovering [17][18].Researchers classed drones as single, coaxial, tandem, and quad-rotor.UAV wings separate rotating and stationary wings [19][20].
The engine type of a drone classifies it, along with other parameters.Example: gasoline engine and electric motor.The bio-inspired flying vehicles with recoil propulsion are atypical UAVs like FESTO AirJelly.This helium-filled ballonet drone has a central electric driving unit and clever adaptive mechanism [21][22]36].Drones consist of five varieties based on their operation: UGV (unmanned ground vehicles), UAV (unmanned aerial vehicles), USV (unmanned surface vehicles), UUV (unmanned underwater vehicles), and USC (unmanned space crafts).Ariel vehicles can be remote-guided or autonomous [23].Researchers also classed the unmanned aerial vehicle by working platform as HAP [24] and LAP [25].Table1 [23] lists three UAV classifications according to U.S. report.Features of a system based on drones Here, we'll explain the major pieces and how they work both individually and in conjunction with one another.The drone frame is the most reliable part because it supports all other parts.Depending on product weight, a carbon frame may be better than a plastic one.The drone's flight depends on the motor's torque.The "pusher prop" counterbalances torque to stabilize the drone.Brushless motors are quieter and more efficient.Brushless motors last longer.Your boat's propellers and motors need weatherproofing and high-velocity air.An ESC circuit adjusts and controls a motor's rotational speed and direction.The flight controller, also known as the ground control system (GSC) or ground cockpit, controls the drone's movements from takeoff until landing.The gyroscope and front propeller ensure stable flight in all directions.The boom is long enough to make certain changes while in flight.Signals also coordinate payloads.This is the UAV operation control centre.
With a magnetometer and GPS, you can also determine your latitude, longitude, altitude, and magnetic heading.To boost power supply performance, you need an efficient motor.Remote pilots can effectively use antennas to get a first-person view of the line of sight.Remotely operating a drone requires only a transceiver and five channels.Drone remote controls must comply.A key component is "Payload," which is the equipment the drone can carry to boost performance.This could be a camera or sensors.The camera will take X, Y, and Z images for object detection, photogrammetry, and collision avoidance.Telemetry allows real-time data monitoring and display on handheld devices. 2 Tank materials

Future Aspects of Drone Technology
UAVs have many uses and are of interest worldwide, thus the commercial and civilian drone markets are increasing rapidly.Businessmen, manufacturers, investors, and service providers can benefit from the new drone trend.[24] Researchers have estimated UAV market value.As seen in Figure 2, the market value exceeds $127 billion.Civil and agriculture industries will dominate UAV market value with $45 billion and $34 billion, respectively.According to the Association for Unmanned Vehicle Systems International, unmanned aircraft will provide over 100,000 jobs by 2025 [21].

Drone in sanitizations
Sanitization was excellent with drones at covid 19 [21][22][23][24][25].Several studies support this.Scientific papers will make the COVID-19 epidemic more professional.Kumar et al. [15] examined drone-based disinfectant spraying networks.This investigation sprayed a twokilometer-radius, ten-minute zone without circumstances data.Alsamhi et al. [16] presented a decentralized drone framework.This study also covered drone disinfectant spraying without details.Khan and colleagues [17], Singla [18] say researchers use drones to sterilize and spray disinfectant.In recent studies, a 16-litre drone disinfected 100,000 square meters.According to this knowledge, there is no standard drone disinfection technique, and tank design, size, and nozzle type must be selected to maximize mission success.However, widespread disinfectant use endangers urban animals and people regardless of technology.Dangers may affect both populations.Khan et al. [17] cited material selection-related human difficulties, while Nabi et al. [24] listed several bad urban environment circumstances.These studies indicated that drone sanitization required proper nozzle, tank, and operating mechanism selection.

Tank Materials
Disinfection drone design relies heavily on the tank material.Make sure you use rust-proof metal while constructing the tank.Polyethylene plastic, stainless steel, and fiberglass are currently used for sprayer tanks.Sanitizers can cause corrosion in some materials.Always be sure your parts are going to work together before you buy them.Never use plastic, aluminum, or galvanized steel tanks.As a result of chemical reactions, the tank's sanitizer may lose its effectiveness, and the tank may rust or corrode.Keep tanks clean to prevent corrosion, scale, dirt, and other impurities from causing damage to the pump and nozzles.Chemical flow can be impeded by contamination in the nozzle, leading to undesirable spray patterns and application rates.Pick a container that has a hole in the bottom for complete water removal.A sump in the bottom of a tank is preferable to any alternative.The top access must be generous in size to facilitate inspection, cleaning, and maintenance within.Insecticide dosing requires knowledge about the tank's capacity.Capacity indicators can be seen on the sides of most contemporary tanks.Include a sight gauge for the fluid level in the tank if it is not transparent.This review paper concludes that polyethylene is the best material for tanks since it is inexpensive, widely available, and relatively lightweight.Due to its compatibility with the environment and its lack of chemical transmission into disinfected products, polyethylene tanks are risk-free.Since it's lightweight and replaceable, it helps keep the drone from getting too top heavy.Since these components are easily accessible, the drone's performance will improve.In

Nozzles
Researchers have provided a number of parameters which effect the life of base materials dealing with slurry suspensions [26][27][28][29][30][31][32][33][34][35][39][40][41][42].Components of drone like nozzle are the best examples for such studies.Nozzles are important in drone sanitization because they mark a target zone to spray either COVID-19 sanitizer or pesticide or fertilizer for agriculture.Nozzles control output flow while maintaining internal and external factors such liquid volume, viscosity, and nozzle shape and size.Nozzle turns blended fluid into desired-shaped and inter-droplet space droplets.Nozzle design prefers brass, plastic, nylon, stainless steel, hardened stainless steel, and ceramic.The most popular nozzle is brass, which is cheaper but wears out faster.Harder metal or material nozzles wear less despite their higher cost.Their use is expensive.When exposed to high-quality chemicals, nylon nozzles swell, making them economical and wear-resistant.
The most typical problems experienced during the actual application procedure are streaks and a clogged nozzle.To avoid streaking, it is essential that the sanitizing liquid be consistent so that it is distributed uniformly throughout all nozzles.Each nozzle on a sprayer must be filled with the same quantity of disinfectant solution.If there is a discrepancy between the amounts of sanitizer liquid supplied by neighbouring nozzles, streaks may appear.There must also be consistent monitoring of the flow rates of each nozzle in relation to the other nozzles.There is roughly a 10% discharge tolerance for a nozzle.if the number of discharges is too high or too low to attain this threshold, adjust the nozzle accordingly.One of the most common and annoying problems with sprayers is a nozzle that becomes clogged.Using the appropriate strainers and filters in the appropriate locations helps alleviate this issue while simultaneously decreasing nozzle wear.The sprayer system's nozzle comprises primarily of three strainers: tank fill strainers, line strainers, and nozzle screens.PVC nozzles were selected because they are readily available and resistant to corrosion.The PVC nozzle has the greatest advantage as compared to others since it allows for a constant and steady stream of liquid (water or chemical).The selected material also reduced flow and frictional resistance in the fluid
