Design and development

The Aeros was designed to comply with the US Experimental - Amateur-built aircraft rules. It features a single main rotor, a two-bladed tail rotor, a single-seat enclosed cockpit with a bubble canopy and skid-type landing gear with integral ground-handling wheels. The standard engine used is a four-cylinder, air-cooled, four-stroke, 97 hp (72 kW) Volkswagen air-cooled engine. [1] [2]

The aircraft fuselage is made from a mix of aluminum and steel tubing. Its 22.0 ft (6.7 m) diameter two-bladed rotor has a chord of 8 in (20.3 cm) and employs a NACA 0012 airfoil. The drive train consists of a primary belt drive connected to a geared transmission built with Volkswagen gears and a belt-driven tail rotor drive. The tail rotor has a diameter of 40 in (101.6 cm) and a chord of 3.5 in (8.9 cm). [1] [2] [3]

The aircraft has an empty weight of 540 lb (245 kg) and a gross weight of 900 lb (408 kg), giving a useful load of 360 lb (163 kg). With full fuel of 12 U.S. gallons (45 L; 10.0 imp gal) the payload for crew and baggage is 288 lb (131 kg). The cabin width is 20 in (51 cm). [1]

The supplied plans include a fully illustrated guidebook and a parts list. The manufacturer estimates the construction time from the supplied plans as 300 hours. [1] [2]
