The ARV Griffin is a Canadian homebuilt aircraft that was designed by Dave Marsden of the University of Alberta and produced by Canada Air RV and later by AC Millennium Corp, both of Edmonton. When it was available the aircraft was supplied as a kit for amateur construction.[1][2][3][4][5]
The aircraft is made from sheet aluminum. Its 35.50 ft (10.8 m) span high aspect ratio wing employs a Marsden-designed IARV 419 airfoil, mounts flaps and has a wing area of 136.00 sq ft (12.635 m2). Winglets were a factory option to improve low speed handling, lateral control and STOL performance. The cabin width is 47 in (120 cm) and the wings detach for ground transportation or storage. The acceptable power range for the Griffin Mark III is 65 to 150 hp (48 to 112 kW) and the standard engines used are the 100 hp (75 kW) Continental O-200A, 80 hp (60 kW) Rotax 912, 74 hp (55 kW) Rotax 618two-stroke or the 100 hp (75 kW) CAM 100 powerplants. Mounts were also available for the 130 hp (97 kW) Subaru EA81, 108 hp (81 kW) Lycoming O-235 and Suzuki engines.[1][3][6][7]
The Griffin Mark III has a typical empty weight of 840 lb (380 kg) and a gross weight of 1,500 lb (680 kg), giving a useful load of 660 lb (300 kg). With a full fuel load of 37 U.S. gallons (140 L; 31 imp gal) the payload for pilot, passenger and baggage is 438 lb (199 kg). The seats are fully adjustable and removable.[1]
The fitting of floats and skis was listed as being under development in 1998. The Mark III kit included all-aluminum parts cut and bent, with fuselage, wing and tail assemblies pre-jigged. The aircraft could be bought as four separate sub-kits. The manufacturer estimates the construction time from the supplied kit as 800 hours for the Mark III and 600 hours for the Mark IV.[1][3][4][5]
Operational historyEdit
By 1998 the company reported that 18 kits had been sold and three aircraft were flying.[1]
Version produced by AC Millennium, with gross weight of 1,730 lb (780 kg), a wing area of 115.5 sq ft (10.73 m2) and powered by a 160 hp (119 kW) Lycoming O-320.[5]
