With advancements in UAV technology, applications for unmanned aircraft are rapidly being developed for
civilian uses, although the military has been using them for over a decade.
Solutions are being hammered out by the FAA to accommodate their use within national airspace and
Lumenosys technology has advanced control systems and sensors small enough for miniature helicopters
and fixed-wing UAVs. For your general information we have provided a summary with research articles
about UAVs and UAV control systems.
CHARACTERISTICS OF UAVS
- UAVs (unmanned aerial vehicle), can have organic parts or hybrid insect micro-electro mechanical
systems. Some UAV projects envision 'cyborg' insects with tiny electronics which can be controlled
remotely.
- Speeds of UAVs may vary from hovering flight for urban 'perch and stare' activity to Mach 6 and
beyond.
- The size and weight of UAVs vary greatly. Currently, very small ones are not regulated and have full
access to the airspace.
MAJOR ISSUES INVOLVING UAVS
Individual privacy is one of the issues that regulatory agencies are trying to resolve for future UAV flight
over civilian airspace. This will unlock the civilian market potentially worth billions. It will also bring flexibility
in development, deployment and training for military customers.
For in the future, one of the most critical places for UAVs to work will be over the densely populated urban
battle fields. However, UAVs already been flying regularly in controlled airspace for many decades as model
aircraft.
The official term used by the FAA (Federal Aviation Administration) for UAV systems is UAS (unmanned
aircraft system). This is used in the place of unmanned aerial vehicle (UAV) because it encompasses
elements beyond the UAV itself. UAS includes the: 1) Unmanned aircraft, which can be a helicopter, fixed
wing or wingless vehicle; 2) Control system 3) Datalink or other support equipment.
Also known as the drone, the UAV is usually without a human pilot, although some military vehicles can be
interchangeable. The flight of the UAV is controlled by computer communication control system within the
vehicle or remotely on the ground or in another aircraft. Today, an increasing number are controlled
autonomously.
USES AND FUNCTIONS OF UNMANNED AERIAL VEHICLES (UAV)
UAVs (unmanned aerial vehicles) control systems (UAS) come in a variety of sizes, shapes and
characteristics. Their function primarily determines the size and shape a UAV (unmanned aerial vehicle) will
take.
The military is the largest user of UAVs (unmanned aerial vehicles) control systems (UAS) although
historically, their prototypes were first used by hobbyists. The variety and uses of unmanned aerial vehicles
by civilian agencies for surveillance and firefighting has grown rapidly.
Basically, UAVs are being used in reconnaissance operations, as target simulation, in combat attack for
high risk battlefield maneuvers, various logistics operations, and for commercial civilian applications.
Two of the most exciting areas UAVs are being developed for are in remote sensing and commercial aerial
surveillance. Electromagnetic sensing mechanisms carried on board the UAV (unmanned aerial vehicle)
encompass radar systems, infrared, near infrared or visual spectrum cameras. Microwave and ultraviolet
spectrum sensors are sometimes used.
The presence of airborne microorganisms and other biological matter can be detected by biological
sensors carried on UAVs (unmanned aerial vehicles) and control system. Laser spectroscopy is used as a
chemical sensor to evaluate concentrations of the various elements in air.
Commercial aerial surveillance using UAVs (unmanned aerial vehicles) control systems (UAS) is rapidly
expanding. Low cost UAVs (unmanned aerial vehicles) or UAS are generally utilized in commercial
surveillance systems to monitor wildfire mapping, home security, anti-piracy operations, livestock monitoring
and policing of the roads. Currently, UAV payloads can carry sensors capable of detecting the movement of
a person taking a breath. See Research Article 1 below.
USE OF UNMANNED AERIAL VEHICLES IN WEATHER PREDICTION
UAVs (unmanned aerial vehicles) are capable of providing atmospheric phenomena observations which
have been difficult to obtain with current weather technology. This is why advances in unmanned aerial
vehicle (uav) technology has become a high priority for researchers working in the atmospheric sciences.
For instance, the 2007 National Research Council Decadal Survey has reiterated that unmanned aerial
vehicle (uav) technology will be included in all strategic plans for the future.
The NOAA (National Oceanic and Atmospheric Administration) has been utilizing UAVs (unmanned aerial
vehicles) control systems to hunt for and monitor hurricanes. UAVs are being designed to actually fly into a
hurricane and transmit real-time information back to the National Hurricane Center.
RUSSIAN COMPANY IS DEVELOPING MINIATURE UAVS
The Russian company Nelk showed for the first time a collapsible aerial reconnaissance complex made on
the basis of the miniature remotely piloted vehicle [RPV] Bumerang. The device was shown at the 5th
International forum and exhibition "Unmanned multirole complexes" which opened in Moscow in 2011.
Bumerang makes in possible for the commander to lift his eyes to an altitude of up to 500 m. and survey a
distance of up to 3 km to carry out tactical reconnaissance, process promptly the information received and
take the right decision. It's unnecessary to look higher or further," the company's representative Sergey
Litvinyuk, has told Interfax-AVN.
He said that in 2010 the Russian military department purchased two complexes within the state defence
order. The complexes include mini-helicopters Kolibri-4 and Kolibri-6. Orders from the country's other
forces and federal structures are expected this year too.
The engineer said that the use of this complex greatly reduces risks. Thanks to noiseless electrical motors,
the vehicle becomes almost invisible and silent at an altitude of 100 m. Kolibri is literally capable of flying
into a small window and inspecting closed premises when it has a payload such as a video or a photo
camera.
THE FUTURE OF UAVS
Research and development scientists are actively searching for other valuable uses for the UAVs
(unmanned aerial vehicles) control systems (UAS), and once the legal issues involving individual privacy
issues concerning their use within the national airspace have been resolved, the development and
production of UAVs will skyrocket. They will eventually be used to scout our national border, hunt for
fugitives and patrol streets.
