Design and development
[edit]The VA115 was designed to comply with the US FAR 103 Ultralight Vehicles regulations, as well as the German 120 kg class and European Class 6 microlight helicopter rules. As its designation indicates, the aircraft has a standard empty weight of 115 kg (254 lb).[1]
The VA115 features dual, coaxial main rotors with NACA 23012 airfoils, a single-seat open cockpit without a windshield, tricycle landing gear and a two-cylinder, air-cooled, two stroke, fuel-injected 50 hp (37 kW) Hirth F23 engine.[1]
The aircraft fuselage is made from metal tubing, with a small cockpit fairing. Its dual two-bladed rotors each have diameters of 4.5 m (14.8 ft). The aircraft has a typical empty weight of 115 kg (254 lb) and a gross weight of 275 kg (606 lb), giving a useful load of 160 kg (353 lb). With full fuel of 19 litres (4.2 imp gal; 5.0 US gal) the payload for the pilot and baggage is 146 kg (322 lb).[1]
Reviewer Werner Pfaendler, described the VA115 as "beautifully engineered".[1]
