The Sikorsky H-34 or S-58 is
a piston-engined military helicopter originally designed by American
aircraft manufacturer Sikorsky as an anti-submarine warfare aircraft for
the U.S. Navy. It has seen extended use when adapted to turbine power by
the British licensee as the Westland Wessex and Sikorsky as the later
S-58T.
The Sikorsky S-58 was developed as a lengthened and more powerful
version of the Sikorsky Model S-55, or UH-19 Chickasaw, with a similar
nose, but with a tail-dragger rear fuselage and landing gear, rather
than the high-tail, 4-post pattern. It retained the nose-mounted piston
engine with the drive shaft passing through the cockpit placed high
above the cargo compartment. The aircraft first flew on 8 March 1954. |

Der Sikorsky H-34 oder S-58 ist
ein Militär-hubschrauber mit Kolbenmotor, der ursprünglich vom
amerikanischen Hersteller Sikorsky als U-Boot-Kampfflugzeug für die U.S.
Navy entwickelt wurde. Es hat ausgedehnte Verwendung erfahren, als es von
dem britischen Lizenznehmer als Westland Wessex und von Sikorsky später als
S-58T mit Turbinentriebwerken ausgerüstet wurde.
Die Sikorsky S-58 wurde als verlängerte und stärkere Version des Sikorsky
Model S-55, oder UH-19 Chickasaw entwickelt, mit einer ähnlichen Nase, aber
mit einem tiefen Heckrumpf mit einem Fahrwerk, anstelle des hohen Schwanzes.
Es behielt den Kolbenmotor im Bug bei, wobei die Antriebswelle durch
das hoch über dem Laderaum platzierte Cockpit fuhr. Der Hubschrauber flog
erstmals am 8. März 1954. |
