Aircraft

All of our primary research aircraft presented here with the exception of the Lawrence Hagrave were constructed by Ray Cooper. Ray recommisioned Lawrence, the #3 Aerosonde.

Deficiencies in the aerodynamics, of which there are very few, are due to Greg Egan who chose the airfoil sections.

P15035

Specifications:

Span: 150 cm
Chord: 35cm
Length: 106 cm
Wing Section: EMX07
Controls: Elevons
Weight range: 2.9 to 4.6 Kg - depends on motor battery and payload configuration
Motor: Actro 40/6 - outrunner direct drive, 16 x 13 Aeronaut Cam Carbon Prop
Motor Battery: 28 x GP3300 NiMh or 9 series x 4 parallel eTec 1200 LiPoly cells
Control System: JR3810 Tx, JR649 Rx, 2 x Hitec wing servos
Launch system: Hand launch able
Flight Duration: 40 to 60 minutes (@ 60kph cruise) depends on batteries and payload
Speed: Stall 33Kph, Cruise 60Kph, Max 150Kph
Auto Pilot: Micro Pilot 28g
Flight termination: Parachute
Payload: Pentax Optio S 3.2 mp with Video down link

Construction:

Fuselage is a simple box structure. Balsa sides and ply formers reinforced with glass cloth inside and out where required.

Motor is soft mounted with rubber machine mounts. All control systems are mounted behind the wing trailing edge, this leaves room for the payload and motor battery to placed to obtain the correct CG.

Wings are white styrene foam covered with 2 layers of 2 & 3 ounce glass cloth. Wing tubes for joiner rod are carbon fibre, the wing joining rod is also carbon fibre. Elevon servos are mounted in the wing.

P16025

Specifications:

Span: 160 cm
Chord: 25cm
Length: 106 cm

Motor: Hacker B40 21L Geared drive (Maxon 5.2:1), 16 x 13 Aeronaut Cam Carbon Prop
Motor Battery: 6 series x 4 parallel eTec 1200 Lithium Polymer cells
Control System: JR3810 Tx, JR649 Rx, 2 x Hitec wing servos
Launch system: Hand launch able.
Flight Duration: 60 to 90 minutes (@ 60kph cruise) depends on battery & payload.
Speed: Stall 30Kph, Cruise 60Kph, Max 135Kph
Auto Pilot: Monash Infrared System (under development)
Flight termination: Parachute
Payload: Pentax Optio S 3.2 mp with Video down link

Construction:

Fuselage is a simple box structure. Balsa sides and ply formers reinforced with glass cloth inside and out where required.

Motor is soft mounted with rubber machine mounts. All control systems are mounted behind the wing trailing edge, this leaves room for the payload and motor battery to placed to obtain the CG.

Wings are white styrene foam cover with Obechi veneer. Wing tubes for joiner rod are carbon fibre, the wing joining rod is also carbon fibre. Elevon servos are mounted in the wing.

Plank Genesis

The plank aircraft have their genesis with an EMX07 wing cut by Ray circa 2000 at John Bird's instigation which lanquished for a few years. It was finally assembled into our first prototype plank (Cornflake video) in mid-2002 by Greg Egan and is still intact. A second prototype also by Greg (Weetie video) with an MH60 was constructed one year later and is also still intact. The designs are quite unusual for planks in that they have distinctive long tail boom yielding excellent low speed stability. The stall behaviour and general robustness of planks when crashed into cargo nets, or just generally into the scenery, is self evident.

Duigan

Specifications:

Airframe: Foam/balsa with glass and carbon fibre skin
Wingspan: 3m
Wing Area: 90dm2
Airfoil: MH62
Mass Empty: 5.5 kg
Payload: 1 kg
Engine: Direct drive Actro 40-6
Batteries: 30x3000mAH NiMH
Airspeed: 55 KpH (Cruise) 100+ KpH (Max)
Endurance: 45 min (Cruise) 15 min (Max)

Duigan Genesis

Duigan took its inspiration in part from Professor John Bird's interest in flying wings, into which we were co-opted, and a desire for a UAV that did not look like just another model aeroplane.


The Lawrence Hargrave

The Lawrence Hargrave is based on the #3 aircraft built by Aerosonde. The aircraft, which is on loan from Aerosonde, has been adapted to suit our research programme. In this form it has significantly lower endurance than the 'production' Aerosonde which in 1998, was the first unmanned, autonomous aircraft to fly the Atlantic Ocean

Specifications:

Airframe: Composite
Wingspan: 2.9 m
Wing Area: 54.88 dm sq
Airfoil: SD7032
Mass: 6.7 kg
Payload: 1 kg (for model regulations)
Engine: Enya 155 (26cc)
Fuel: 4 stroke (5 lt)
Airspeed: 65 Kph (Cruise) 120 Kph (Max)
