The Vertical Hummingbird is an American helicopter, produced by Vertical Aviation Technologies of Sanford, Florida that was introduced in 1991. The aircraft is supplied as a kit for amateur construction.[1][2]
Design and development
The Hummingbird is a development of the certified Sikorsky S-52 that first flew in 1947, adapted to kit form. The aircraft features a single main rotor, a four-seat enclosed cabin, quadracycle landing gear and a choice of two powerplants.[1] The prototype was converted by Vertical Aviation Technologies from a Sikorsky S-52-3.[3]
The Hummingbird fuselage is made from riveted aluminum sheet. The nose section is adapted from the Bell 206. Its 33 ft (10.1 m) diameter fully articulated three-bladed main rotor employs a NACA 0015 airfoil. The two-bladed tail rotor has a diameter of 5.75 ft (1.8 m). The aircraft has an empty weight of 1,850 lb (839 kg) and a gross weight of 2,800 lb (1,270 kg), giving a useful load of 950 lb (431 kg). With full fuel of 57 U.S. gallons (220 L; 47 imp gal) the payload is 608 lb (276 kg).[1][4][5]
