T-PARC 2008operations meeting April 2008DLR research flight facilities
Plans for the DLR Falcon operation during T-PARC deployment time in Japan: 25 August - 4 October 2008 flight hours in Japan: 90 Planned transfer route: Germany-Moscow-Surgut-Bratsk-Khabarovsk-Japan – joint research program under discussion main scientific goals: improved typhoon track prediction investigation of extra-tropical transition of trop. cyclones potential of lidar for operational future observing system contact persons: Martin.Weissmann@DLR.DE (PI) Andreas.Doernbrack@DLR.DE (CO-PI) Andrea.Hausold@DLR.DE (aircraft operations) 1500 NM 1000 NM 500 NM max. range of DLR Falcon: 1500 NM max altitude: 12.8 km (42.000 ft)
universal window interface at the right side of fuselage (220 mm diam.) large opening at the left side of fuselage (250 mm x 570 mm) 4 openings on top of fuselage (80 mm diam.) new generation engines with additional electrical generators (2x300A @ 28V) 1 large opening on top of fuselage (515 mm diam.) 4 hard points under the wings to carry up to 4 particle probes 1 hard point under the fuselage (external equip-ment, particle probes) multiple temperature sensors and inlets for standard sensor package nose boom with flow angle sensor (CFK, 1.8 m length) hardpoint for radiometer installation 2 coverable large openings In the bottom of fuselage (515 mm diameter) meteorological sensor package (temperature, pressure, humidity, wind) DLR Falcon 20-E5, D-CMET – special equipment

Aircraft operation - general Aircraft-equipment and crew-rating: fully IFR for International Operation, RNAV, RVSM, Long Range Pilots holding ATP-License Refuelling (Jet A1): single point or gravity fuel-carnets from ESSO/BP/SHELL/Multi-Service Type of operation: non-commercial, private, arial work fully unrestricted civil registration and operation no Diplo-Clearance-Application (valid only for state or military aircraft) Classified security level Survival Equipment: Life Raft, Life Vests, ELT Transmitter + Radio DLR Team 2 Pilots 1 Aircraft engineer 1 Aircraft team manager 2 persons for data acquisition Lidar scientists and technicians Meteorologists DLR project leader --------------------------------------------- 6-23 persons on site office space: for 10-15 persons (with internet access, telephone etc.) Separate room for data download and preprocessing facilities; in total 2-3 rooms lodging and offices at the airport are preferred
~ 16.4 m Overall wingspan ~ 19.5 m (incl. noseboom) Aircraft ground requirements • hangar - mainly to avoid large temperature changes of the lidars: • 21.5 x 24.5 x 6.5 m (width, depth, height, incl. buffer); 5.4 m tail height
external power receptible 32 Amps 3phase 400 V receptible 32 Amps 3phase 400 V plug Aircraft ground requirements • ground power: • 28VDC 500A continuous power, 1000A for engine start • standard 28Volt DC external power recepticle • for use of DLR‘s ground power: 400V@50Hz 3Phase 32Amps
Desired operation • Targeted observations based on sensitive area predictions and meteorological weather phenomena • Launch of dropsondes • Flight routes off-airways • Flight level 270 - 370 • Night time / weekend operation • Access to aircraft for crew / scientists also during night time / weekends • overnight stop at Okinawa (Kadena AB (RODN) or Naha airport (ROAH)) • Refueling stop at Iwo Jima (RJAW) ?? • Refueling stops at civil / (military?) airports in Taiwan, Japan, South Korea, Russia (only during transfer flight)
Limitations • Aircraft: • Max. crosswind component during take-off and landing: 20 (25) kts • max. flight altitude: FL 420 – can only be reached at end of the flight for 45 – 60 minutes – initial climb to FL 350/360, stay there for about 1.5 hrs, then continue climb to FL 380, stay there for a while, then final climb • has to be parked inside hangar before taifun may hit – especially important for deployment in Kadena (also not close alternate airport!) • max. range: strongly depends on wind and availability of suitable alternate airport, 1200 – 1500 NM • Crew duty times (defined by law): • day-off after 6 days at the latest • normal duty time: 10 hrs, then 10 hrs rest time; can be extended to max. 14 hrs (max. 8 hrs in total in 7 days); rest time grows accordingly
