MetAir Let’s SHARE the Egrett SHARE – Small High Altitude Research Aircraft for Europe Jorg M Hacker Director/Chief Scientist ARA – Airborne Research Australia FLINDERS UNIVERSITY ADELAIDE (cid:122) AUSTRALIA Why does ARA want to embark on the SHARE adventure ? • Increase the use of the aircraft for science • Not clear at this stage, if ARA alone would be able to continue operating the Egrett with the resources available in Australia • No Australian use of the Egrett • Perceived need for (relatively) low cost medium-high altitude platform in Europe The Egrett series of high-altitude aircraft Egrett – E-Systems / Grob / Garrett Several single-seaters, one two-seater/trainer (G520T) Designed as “the poor man’s U2” – to fly missions along the “Iron Curtain”; Program halted when “Iron Curtain” fell One of single seaters operational at Raytheon, Van Nuys (military applications) Prototype Single seater has been used for science long ago (STRATO 1) - Not operational any more Two-seater operational at ARA – Airborne Research Australia, Adelaide “spying on the environment” Egrett two-seater (S/N 10200, VH-ARA) • First flight 21 April 1993 • Acquired by ARA in 1998 from VEBEG, through an auction (DM 3M); • Modified in collaboration with Grob and DLR (at approx. 1MEuro): • Hardpoints under wings • Under wing pylons, pods and masts • Electrical system for science • Extensive wiring (e.g. for PMS probes) • All certified to FAR 23 ‘Normal’ Category • Composite airframe. • Fuselage and tailplane mainly glass fibre reinforced epoxy • Wings carbon fibre reinforced epoxy. • MTOW 4,700kg • Single engine turbo prop, Garrett TPE331-14F. • Cabin pressurised 6 psi – ie. Cabin at ~22,000ft when aircraft at max altitude • IFR-certified (but not RVSM compliant) • ‘Known Icing’ certified (without stores only). • Liquid oxygen system for crew supply • Owned and operated by Airborne Research Australia since April 1998 • TTIS at registration in Australia was 216 hours, 185 cycles • Most recent flight was on 7 April 2007 – currently 1066 hours, 565 cycles. Science project using the ARA G520T Egrett: 1998 – 2006: Turbulence Measurements in and around the Jetstream, as well as mountain waves over Australia, Japan and SW-England; funded by a series of grants from the US Air Force and other US agencies; 150 mission hours + ferry to/from Japan (~50hrs) 2001: The AberEGRETT campaign studying mountain waves, turbulence and tropospheric/stratospheric exchange over SW-England; funded by NERC/UK; 70 mission hours + ferry to/from Europe (~80hrs) 2002 – 2005: The EMERALD campaigns - study many aspects of cirrus clouds and thunderstorm outflow over Southern and Northern Australia using cloud physics instrumentation and lidar; funded by NERC and Canadian sources; 150 mission hours 2003: The NEXST campaign - verification of wind and turbulence measurements for SST tests over Southern Australia; funded by Japanese sources; 35 mission hours 2005-2006: The ACTIVE and TWP-ICE campaigns in Darwin/Australia, studying thunderstorms, monsoon and air chemistry over Northern Australia (in concert with the Proteus, the Geophysica, our DIMO and others); funded by NERC/UK and other contributions; 120 mission hours 2007: The GoSAT campaign - verification of Japanese satellite sensor measuring CO2 and CH4, Southern Australia; funded by Japanese sources; 30 mission hours *** ALL FLYING WITH EGRETT WAS FUNDED FROM NON-AUSTRALIAN SOURCES *** ARA Egrett Operational Environment What is ARA – Airborne Research Australia? • 100% self-funding research institute hosted by Flinders University, Adelaide, Australia no base-funding or subsidies from University or government at all, except one-off grant from the Australian Government to set up facility (A$8.5M), but no on-going operations support • Designated “Australia’s National Research Aircraft Facility” • Currently owns and operates 4 research aircraft (also sometimes operates other research aircraft) • Based at large, modern Operations Base at Parafield Airport near Adelaide, Australia • Staff: • Director/Chief Scientist; • 1 p/t scientist; 1 p/t engineer/technician; 2 p/t operations/admin staff • contract pilots and others • ARA operates the Egrett under an International Air Operator’s Certificate (AOC) (and other aircraft) issued by CASA (Civil Aviation Safety Authority, Australia) – this allows un-restricted operations (“Aerial Work”) world-wide • Science installations are usually certified to CASA regulations (final certification normally out-sourced to Engineering Company under CAR35) ARA Airborne Research Platforms Part 1 – special design aircraft owned by ARA Diamond Aircraft HK36TTC ECO-Dimona VH-EOS Diamond Aircraft HK36TTC ECO-Dimona VH-OBS Grob G520T Egrett VH-ARA Grob G109B VH-HNK ARA Airborne Research Platforms Part 2 – other aircraft modified and used by ARA for airborne projects Aerocommander 690 with L-Band antennas Cessna 404 with atmospheric sensors on nosecone Beechcraft 200T Super King Air with atmospheric sensors on wingtips Flying hours of ARA research aircraft: Egrett All ARA a/c 1998: 95 500 1999: 131 784 2000: 188 600 2001: 99 491 2002: 138 705 2003: 21 352 2004: 5 167 2005: 72 648 2006: 96 575 2007: 14 402 1998-2007: 859 5224 ARA Operations Base (cid:11) A 3,600m2 site at Parafield Airport about 15km north of Adelaide CBD (cid:11) offices and workspace for staff and visitors (cid:11) mechanical and electronic workshops (cid:11) calibration facilities (cid:11) computing facilities (cid:11) safe storage for instrumentation (cid:11) meeting rooms (cid:11) ground support vehicle (cid:11) briefing, mission planning and preparation facilities.
