    • The present invention regards a watercraft vehicle (1) having a propeller shaft (9) coupled to a motor (3) and a propeller (7) forming a propeller disc (11) having a hub (17). A first blade (8) of the propeller (7) is hingedly coupled to a first oblique lag-pitch hinge (22') of the hub (17) and a second blade (10) of the propeller (7) is hingedly coupled to a second oblique lag-pitch hinge (22'') of the hub (17). The first oblique lag-pitch hinge (22') being oriented in a direction oblique to the axis of rotation (RX) and parallel with the second oblique lag-pitch hinge (22''). A control circuitry (5) provides a first thrust (T') in a first arc segment (13') of the propeller disc (11) and provides a second thrust (T'') in a second arc segment (13'') of the propeller disc (11) by controlling a rate of change of shaft (9) rotational velocity, wherein a first propeller blade pitch change is achieved about the first oblique lag-pitch hinge (22') and a second propeller blade pitch change is achieved about the second oblique lag-pitch hinge (22''). The present invention also regards a method of manoeuvring the watercraft vehicle (1).

    • A circulator device comprising a large diameter fan having reinforced fan blades with a tapered airfoil shape is disclosed. The fan blades may be formed using an extrusion method of fabrication, wherein each fan blade (316) may comprise a reinforced trailing edge (514) with a downwardly extending flange. The benefit of forming each fan blade with a reinforced trailing edge (514) of the present invention results in improved structural characteristics such that the trailing edge of each fan blade (316) may be fabricated longer so as to improve aerodynamic performance. Also, the reinforced trailing edge resists tearing that my occur during extrusion by adding the bent flanged region to at least one distal end of the trailing edge. For example, the bent portion (538) of the trailing edge tends to rigidly orient the extruded material in a stabilized position more readily during formation.
    • 公开了一种包括具有锥形翼型的加强风扇叶片的大直径风扇的循环器。 风扇叶片可以使用挤压制造方法形成,其中每个风扇叶片(316)可以包括具有向下延伸凸缘的加强后缘(514)。 用本发明的加强后缘(514)形成每个风扇叶片的益处导致改进的结构特征,使得可以制造更长的每个风扇叶片(316)的后缘以便改善空气动力性能。 此外,加强的后缘抵抗在挤压期间发生的撕裂,其将弯曲的凸缘区域添加到后缘的至少一个远端。 例如,后缘的弯曲部分(538)倾向于在形成期间更容易地将挤出的材料刚性地定向在稳定的位置。
