Presentation Transcript

  1. COST ES0802 MC/WG MeetingCambridge, September 20th – 21st, 2010Determination of the conflict potential in case of use of UAS in non-segregated airspaceDipl.-Phys. Mirsad Delić (DLR, Institute of Flight Guidance)

  2. Content • Simulation environment • Investigated parameters • Results • Conclusion

  3. Simulation environmentDLR Traffic Simulator • Real-time and fast-time simulation • Physically correct simulation of aircraft through the use of BADA performance data • Used scenario is based on radar data of a high traffic operations day in Germany in September 2008 • More than 10.000 aircraft movements

  4. Simulation environmentDLR Traffic Simulator

  5. Investigated parameters (1) • UA Types • HALE: High Altitude Long Endurance • MALE: Medium Altitude Long Endurance • Altitude • HALE: 41.000ft (12500m) • MALE: 25.000ft (7500m) • Climb strategies • HELIX: Climb in a helix-like structure above the airfield / airport • DIRECT: Climb along the cruising route

  6. Investigated parameters (2) • Separation • Horizontal: 5NM, vertical: 1000ft (today’s standard) • Horizontal: 10NM, vertical: 1500ft • Horizontal: 10NM, vertical: 2000ft • Variation of takeoff time between 5:00 am and 10:00 pm in steps of twenty minutes • Different mission scenarios have been investigated: • National: Schleswig/Jagel ► Ingolstadt/Manching • International: Schleswig/Jagel ► Paris - Orly • National (civil): Egelsbach ► Schleswig/Jagel

  7. Results (1)Relation between HALE and MALE UA

  8. Results (2)Relation between HELIX and DIRECT climb strategy Used scenario: MALE UA, Schleswig / Jagel > Ingolstadt / Manching, Separation: 10NM, 2000ft

  9. Results (3)Relation between HELIX and DIRECT climb strategy Used scenario: MALE UA, Egelsbach > Schleswig / Jagel, Separation: 10NM, 2000ft (Egelsbach is located in the vincinity of Frankfurt/Main Airport)

  10. Results (4)Relevance of takeoff time

  11. Results (5)Relevance of takeoff time

  12. Conclusion • Number of conflicts is highly depending on • Selected altitude • Climb strategy • Departure airport and surrounding airports • Crossing of highly frequented ATS routes • Recommendation is depending on the mission scenario • Simulation shall be used to create an assistive mission planning tool for integration into DLR’s Generic Ground Control Station efforts

  13. GCS mission planning tool • Extension to existing DLR simulation environment • Requires input of important parameters • Waypoints • Traffic data • Payload • Take-Off time • Cruise altitude • Simulation checks for potential conflicts based on given parameters • Recommendations of solutions if high conflict potential is found
