Harbin 47
Harbin Aircraft Manufacturing Corporation
Type: Flightboat
The Harbin 47 is an all-metal gull winged flying boat and is operated by a crew of four and is intended to carry a payload of 500 kg or four passengers.
The elegant Ha-47, sometimes referred to as the "most beautiful flying-boat ever built", is of all-metal construction. The hull has a central keel and a defined step; the wings are of gull wing configuration, the outer sections being equipped with fully retractable narrow stabilising wing-floats.
Its four engines, Huang Po diesels, are mounted in tractor/pusher pairs in tandem nacelles located at the joint between the dihedral and horizontal wing sections. The rear (pusher) engines could be swung upwards through 10° during take-off and landing, to prevent contact between the three-blade airscrew and water spray created by the forward propellers. The tail unit was of conventional design, comprising a horizontal tailplane and a single, vertical fin with rudder. The good aerodynamic shape is good for the speed and the range of the aircraft.
