  • Propulsion unit for maritime vessel including a nozzle exhibiting a curved following edge at the outlet of the nozzle
    Patent number: 9821896
    Abstract: Propulsion unit (11) for propulsion and maneuvering of a maritime vessel, which includes a nozzle (12) exhibiting a curved following edge (12) at outlet of the nozzle (12), which results in that length of the nozzle (12) is longer in upper part of the nozzle (12) and shortest at the outermost points of a horizontal central axis through the nozzle (12), when the nozzle (12) is seen from behind.
    Type: Grant
    Filed: April 26, 2013
    Date of Patent: November 21, 2017
    Assignee: Rolls-Royce Marine AS

  • Propulsion unit for maritime vessel
    Patent number: 9676460
    Abstract: Propulsion unit (11) for propulsion and maneuvering of a maritime vessel, which includes a nozzle (12) wherein a propeller section (13, 13a) is arranged, which propeller section (13, 13a) is electrically or hydraulically driven, which propulsion unit (11) includes a fastening device (16) arranged for arrangement to hull of the vessel or to a steering device arranged for steering and/or moving the propulsion unit (11). The fastening device (16) is formed by two stems (17a-b) extending in parallel or laterally reversed about an vertical central axis from an upper surface of the nozzle (12) of the propulsion unit, which stems (17a-b) end in a fixing flange (18) for thereby providing an opening (19) which provides the propulsion unit (11) with improved hydrodynamic performance.
