  • Hurricane cleanup, shark patrol top UAV applications

    Another month, another hurricane in the southern United States. News channels showed drone-captured video of the mess left behind in Northern Florida, Georgia and the Carolinas. More useful is the video damage assessments UAVs are providing for first responders.

    A basketball hoop and backboard hang forlornly while both front and back walls of a school gym are gone, huge buildings are nothing but matchsticks, fallen trees and powerlines blocking roads — familiar scenes from hurricane Michael’s devastation of Panama City and area — video provided by drones operating in the disaster zone.

    Although the videos have now largely gone from the TV news, Panhandle residents will be living through this nightmare for months to come.

    Working with emergency teams — including the North Carolina Surf City Fire Department, Airborne Response, Florida FEMA Task Force and Missouri Task Force FEMA — Edgybees’ AR drone software was able to provide collaborative, real-time, situational visualizations of the areas affected by Michael. Status and location updates were available during critical missions, and key geographical data was provided to teams on the ground.

    Beach Patrol

    Another life-saving drone application comes from the other side of the Pacific – finding and deterring sharks which threaten bathers off the beaches of Australia.

    An artificial intelligence application on-board a SharkSpotter UAV monitors for shark attributes as it overflies inshore areas where the predators are known to hunt. If there is a match for typical shark behavior — size, shape, color, and movements in the water — an alert is transmitted to enable lifesavers to respond. The drone can even drop a flotation device to swimmers in trouble. A number of beaches in New South Wales were patroled this past summer, and many more UAV beach patrols are planned to be added for the coming season.

    Other work is underway to deter the animals using devices in the water which create electric fields aimed at interfering with shark sensory systems. Another cell-phone application estimates the probability of the presence of sharks based on a number of environmental factors. Several U.S. agencies are keenly watching these developments as shark attacks have increased here, off both Atlantic and Pacific beaches.

    Meanwhile, there has been another important step forward for drone integration into the US National Airspace System (NAS) and for integration in other countries’ airspace. Enabling drones to fly over people and property is a key part of potential airspace operations, and a safe recovery system which avoids possible injury to people is becoming essential. Most drones have a return-to-base fallback in the event of loss of the control signal, but this doesn’t help in the event of a fundamental mechanical failure.

    Parachute Recovery Systems

    Effective auto-release parachute systems may be key to solving this problem. Another supplier has emerged with a lightweight automatic system for the DJI Matrice 600 multicopter.

    Drone Rescue (DR) from Austria has announced its DR-10 parachute recovery system,for drones weighing 5-20 kg (11-44 lb). The DR-5 system is for lighter UAVs (8kg – 17.6lb).

    The DRS-M600 system has apparently been derived from the DR-10 specifically for the DJI Matrice drone.

    The parachute is mounted in a carbon cage and is released when a self-contained electronics system automatically detects an imminent crash. DR claims that their system works even in the event of control data link failure, and that incident data is collected in an on-board UAV flight-data recorder for subsequent analysis.

    It was previously announced that an FAA waiver for flight over people was granted to North Dakota UAS operator, Botlink using a ParaZero Israel drone recovery parachute system.

    Initial flights were conducted during a tailgating event prior to the North Dakota State University vs South Dakota State football game in North Dakota. The drone flew over crowds in the stadium’s parking lots and provided real-time video for local law enforcement and media companies.

    This drone parachute safety system includes a fully autonomous triggering system that deploys quickly and reliably without being dependent on any manual operator’s response. During FAA testing it was necessary to demonstrate that the descent rate was slow enough to provide acceptably low impact energy and that the system would operate correctly in multiple types of failure conditions.

    DHL Drone Delivery

    Meanwhile, DHL has joined other drone delivery companies to establish a medical delivery trial in Africa. DHL’s trial is in the Lake Victoria region of Tanzania.

    The six-month trial has focused on delivered medicines by UAV within 40 minutes to an island in Lake Victoria — the trip normally takes six hours by road.

    Over the course of 160 proving flights, using a 4-kg-capacity Wingcopter, medical supplies were successfully transported over the 60 kilometers between Mwanza and the hospital on the island of Ukerewe.

    The medicines reach their destination at least 3 hours earlier than by any traditional mode of transportation, and as a result of these tests, 400,000 people in the Ukerewe District will now have access to medical care and support in hours rather than days.

    Conclusion

    Drones helping out hurricane Michael recovery efforts in the Florida Panhandle, specialized drones tracking sharks to mitigate possible attacks off beaches in Australia, parachute recovery systems enabling drone flights over people, the integration of drones into regular airspace moving ahead, and more medical delivery trials in Africa. These are a few recent UAV applications that appear to be supporting even further drone use around the world.

  • Parachute system for drone rescue to debut at Intergeo 2018

    Drone Rescue will present its parachute systems DRS-5 and DRS-10 to the professional public for the first time at Intergeo, at stand 12.0B.112 in Hall 12, Oct. 16-18.

    Parachute rescue system DRS-5 is designed for multicopters with a total weight of up to 8 kg. The system consists of a carbon cage in which the parachute is stored, as well as the associated electronics.

    The electronics, including the sensors, monitor the flight status of a drone independent of the flight controller. A sophisticated algorithm merges this sensor data, through which an automatic crash detection can be realized, the company said. In an emergency, the pilot no longer needs to react and press an eject button. (Often, this is technically no longer possible anyway, such as with a failure of the radio link.)

    Furthermore, the algorithm reacts faster than the pilot: the system ejects the parachute itself. All flight data and movements are recorded in a black box. In an emergency, these can be read out at the request of the customer and made available to insurance companies or authorities.

    “Our goal is to ensure that even in an emergency beyond visual line of sight the drone can be safely intercepted. With our parachute system, that is always possible, due to the electronics that are completely separate and independent of the flight controller,” said Andreas Ploier, CEO and co-founder of Drone Rescue. “In addition, our system has the advantage that it manages completely without explosive, pyrotechnical solutions. Consequently we have a system that is considerably lighter, and functions even in a worst-case scenario.”

    The reliability of the system has been verified in extensive tests by Joanneum Aeronautics in Graz, Austria. In the framework of the tests, 100 flights were conducted during which the parachute system was ejected.

    Half of the flights were conducted with a DJI F550 weighing 1.6 kg. The rest of the tests were performed with the 3.8 kg Vulture, which was developed by the FH Joanneum.

    In both cases, the DRS-5 was attached to the side of the main body of the drone. In each of the tests the parachute was ejected at a height of 30 meters. Every test was documented.

    Furthermore, the data were saved both in the flight controller as well as in the DRS-5 sensor system. After every 10th test, the parachute system was subjected to a visual examination and checked for possible damage or wear.

    “After conclusion of the tests, it can be recorded that all 100 flights were successfully completed,” Ploier said. “In every test the multicopter landed safely. Thereby, the kinetic energy was significantly below the limit of 79 J. All requirements specified by the European Aviation Safety Agency (EASA) were observed.”

    Besides the DRS-5, the structurally identical parachute system DRS-10, which is designed for multicopters with a total weight between 5 and 20 kg, will also be presented at  Intergeo 2018. “The DRS-10 system functions exactly the same as the DRS-5 and falls back on the same components. These are constructed identically, just oriented for a higher payload. The functioning method of both parachute systems is identical,” Ploier said.

    With flight tests for the DRS-5 completed in late summer, the first systems will be delivered to end customers in winter 2018.
