Design and development


The Livella Uno was designed to comply with the US FAR 103 Ultralight Vehicles and the European 120 kg class ultralight aircraft rules. It features a dual coaxial main rotors, with an inverted V-tail, a single open-air pilot's seat without a windshield, tricycle landing gear and a 40 hp (30 kW) Wankel Aixro XH40 engine.[1]

The aircraft fuselage is made from tubing. Its two-bladed rotors have a diameter of 3.8 m (12.5 ft). The aircraft has a typical empty weight of 85 kg (187 lb) and a gross weight of 195 kg (430 lb), giving a useful load of 110 kg (243 lb).[1]

The aircraft mounts a Galaxy Rescue System ballistic parachute in the rotor mast. It also has a small electric motor to power the rotor system from a battery in the event of an engine failure, allowing five minutes of power to land, since the low inertia rotor blades may not support autorotation.[2]
