Drones
How Do Drones Work
An unmanned aerial
vehicle, commonly known as a drone, is an aircraft without a human pilot
aboard. UAVs are a component of an unmanned aircraft system; which include a
UAV, a ground-based controller, and a system of communications between the two.
One
of the most popular drones on the market is the DJI Phantom 3. This drone
was very popular with professional aerial cinematographers. While slightly old
now, it uses plenty of advanced technology which is present in the very latest
drones. This UAV is ideal to explain drone technology because it has everything
in one package. It includes the UAV, gimbal and camera and uses some of
the top drone technology on the market today.
Unmanned
aerial vehicle technology covers everything from the aerodynamics of the drone,
materials in the manufacture of the physical UAV, to the circuit boards,
chipset and software which are the brains of the drone.
How Drones Work
A typical unmanned aircraft is made of light composite materials
to reduce weight and increase maneuverability. This composite material strength
allows military
drones to cruise at extremely high altitudes. Drones are
equipped with different state of the art technology such as infra-red cameras
(military UAV), GPS and laser (military UAV). Drones are controlled by remote
control system also sometimes referred to as a ground cockpit.
An unmanned aerial vehicle system has two parts, the drone itself
and the control system.
The nose of the unmanned aerial vehicle is where all the sensors
and navigational systems are present. The rest of the body is complete
innovation since there is no loss for space to accommodate humans and also
light weight. The engineering materials used to build the drone are highly
complex composites which can absorb vibration which decreases the noise
produced.
DRONE APPLICATIONS
Drones
are used in many areas and what’s more, there is no end when it comes to their
possibilities. Therefore, the areas of applications are numerous today and
there is the growing use of drones all around the world.
Main areas of applications:
·
Search and rescue – Drones are very useful in searching and
rescuing operations. For example, they are used in firefighting to determine
the amount of the certain gasses in air (CO, CO2, and the like) using
the special measuring equipment.
·
Security – Many authorities use drones to protect people during
various emergencies. For instance, they are able to help coordinate a variety
of security operations and can preserve evidence alike.
·
Inspections – Many systems such as power lines, wind turbines, and
pipelines can be checked by drones.
·
Surveillance – A drone allows recording and monitoring from the
sky, and therefore, they are suitable to monitor public events, protests, or
any suspicious happening without being heard and seen. A great tool for the
police!
·
Science & research– They help scientists a lot in research works
to observe different occurrences in nature or a particular environment from the
sky. For example, drones are used to document the archaeological excavations, in
nuclear accidents (measuring contamination), in glacier surveillance, to
observe a volcanic eruption, etc.
·
Aerial photography & video – With a drone that is equipped with an
HD camera, you can take the fascinating photos and shot footage of great quality
from the sky.
·
Surveying & gis (mapping) – Using
multi-spectral cameras and laser scanners, drones are able to create
high-quality 3-D maps. Therefore, they found applications in various areas,
including remote sensing, surveying & mapping, photogrammetry, precision
agriculture, etc.
·
Unmanned cargo system – Drones also serve in delivering of
lightweight packages and bundles of all sorts. This way, you can have a safe,
environmentally friendly and fast transport of goods by air
