Abstract: The invention relates to a method and a system for providing current from a DC power supply to pulsed loads in an array. The array comprises at least two electronic units. Each electronic unit comprises a regulator connected to an energy storage, to a pulsed load and to a charge control unit. The charge control unit is arranged to control the supply of DC current to the pulsed load connected to the electronic unit. The method comprises: selecting a pulse load pattern for the pulsed loads, selecting a charge control sequence by a control system connected to the electronic units and the DC power supply, starting the selected charge control sequence, starting the pulse load pattern, providing DC current from the DC power supply to each electronic unit at different times according to the selected charge control sequence set by the charge control unit.

Abstract: 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).
