UAV and UAS

We believe one of our best areas of focus for UAV and UAS systems is in the Vertical Take Off and Landing (VTOL) using our Coaxial Drive System (CDS) technology.

Secondly, we will excel in high speed UAV applications. Utilizing the Barger Tech Ltd. PowerMax propulsion systems, we can adapt to the various applications you currently have or desire to design, build, and commercialize in the public or private market spaces.

At Aerovation Tech, we know that the Barger Tech Ltd. PowerMax engine technologies we used in our Alien RX2 project can be used to propel UAV and UAS systems. Please contact us for any needs you may have in these areas so we may respond with a solution that meets your requirements.

In the United States, the United States Navy and shortly after the Federal Aviation Administration have adopted the name unmanned aircraft (UA) to describe aircraft systems without a flight crew on board. More common names include UAV, drone, remotely piloted vehicle (RPV), remotely piloted aircraft (RPA), remotely operated aircraft (ROA). These "limited-size" (as defined by the FAI) unmanned aircraft flown in the USA's National Airspace System, flown solely for recreation and sport purposes such as models, are generally flown under the voluntary safety standards of the Academy of Model Aeronautics, the United States' national aero modeling organization. To operate a UA for non-recreational purposes in the United States, users must obtain a Certificate of Authorization (COA) to operate in national airspace. At the moment, COAs require a public entity as a sponsor. For example, when BP needed to observe oil spills, they operated UAVs under a COA granted to the University of Alaska Fairbanks. COAs have been granted for both land and ship borne operations.

The term ‘Unmanned Aircraft System’ (UAS) emphasizes the importance of other elements beyond an aircraft itself. A typical UAS consists of the:

• unmanned aircraft (UA)
• control system, such as Ground Control Station (GCS)
• control link, a specialized data link
• other related support equipment.

The term UAS was since adopted by the United States Department of Defense (DOD) and the British Civil Aviation Authority (CAA).

UAVs typically fall into one of seven functional categories (although multi-role airframe platforms are becoming more prevalent):

• Target and decoy – providing ground and aerial gunnery a target that simulates an enemy aircraft or missile
• Reconnaissance – providing battlefield intelligence
• Combat – providing attack capability for high-risk missions (see Unmanned combat air vehicle)
• Logistics – UAVs specifically designed for cargo and logistics operation
• Research and development – used to further develop UAV technologies to be integrated into field deployed UAV aircraft
• Civil and Commercial UAVs – UAVs specifically designed for civil and commercial applications
• They can also be categorized in terms of range/altitude.

UAVs perform a wide variety of functions. The majority of these functions are some form of remote sensing; this is central to the reconnaissance role most UAVs fulfill. Less common UAV functions include interaction and transport.

UAV remote sensing functions include electromagnetic spectrum sensors, gamma ray sensors, biological sensors, and chemical sensors. A UAV's electromagnetic sensors typically include visual spectrum, infrared, or near infrared cameras as well as radar systems.

Commercial aerial surveillance

Aerial surveillance of large areas is made possible with low cost UAV systems. Surveillance applications include: livestock monitoring, wildfire mapping, pipeline security, home security, road patrol and anti-piracy.

UAVs are increasingly used for domestic police work in Canada and the United States (a dozen US police forces had applied for UAV permits by March 2013).

UAVs can be used to perform geophysical surveys, in particular geomagnetic surveys where the processed measurements of the differential Earth's magnetic field strength are used to calculate the nature of the underlying magnetic rock structure. Knowledge of the underlying rock structure helps trained geophysicists to predict the location of mineral deposits. The production side of oil and gas exploration and production entails the monitoring of the integrity of oil and gas pipelines and related installations. For above-ground pipelines, this monitoring activity could be performed using digital cameras mounted on one, or more, UAVs.

UAVs can transport goods using various means based on the configuration of the UAV itself. Most payloads are stored in an internal payload bay somewhere in the airframe. For many helicopter configurations, external payloads can be tethered to the bottom of the airframe.

Unmanned aircraft are unique for penetrating areas which may be too dangerous for piloted craft.

UAVs will likely play an increased role in search and rescue in the United States. This was demonstrated by the use of UAVs during the 2008 hurricanes that struck Louisiana and Texas. Micro UAVs, such as the Aeryon Scout have been used to perform Search and Rescue activities on a smaller scale, such as the search for missing persons.

In June 2012, WWF announced it will begin using UAVs in Nepal, to aid conservation efforts, following a successful trial of two aircraft in Chitwan National Park, with ambitions to expand to other countries, such as Tanzania and Malaysia.

Another application of civil UAVs is prevention and early detection of forest fires. The possibility of constant flight, both day and night, makes the methods used until now (helicopters, watchtowers ...) becoming obsolete.

Because UAVs are not burdened with the physiological limitations of human pilots, they can be designed for maximized on-station times. The maximum flight duration of unmanned, aerial vehicles varies widely. Internal-combustion-engine aircraft endurance depends strongly on the percentage of fuel burned as a fraction of total weight, and so is largely independent of aircraft size. One of the uses for a high endurance UAV would be to "stare" at the battlefield for a long period of time to produce a record of events that could then be played backwards to track where improvised explosive devices (IEDs) came from.
