    摘要: A rotary blade (28) includes a blade tip assembly (34) with a first bus bar segment (46) and a main blade assembly (32) with second bus bar segment (48). The first bus bar segment is connected to the blade tip assembly and the second bus bar segment is connected to the main blade assembly. The blade tip assembly is connected to the main blade assembly such that the first and second bus bar segments are longitudinally offset from one another. A low-profile interconnect (100; 200) spans the first and second bus bar segments for resistively generating less heat than the bus bar segments for a predetermined current flow.

    摘要: A rotor blade assembly for providing vertical lift to an aircraft, having a rotor head and a plurality of blades, with each blade attached to a mechanism such as a cam surface, whereby movement of the mechanism causes the radial distance between the distal tip of the attached blade and the center of the rotor head to alter, decreasing or increasing the length of the lifting surface. The blades are moved from a fully extended position providing maximum lift, to a retracted position in which the blades are removed from the airstream. The pitch of the blades may be controlled by a pitch controller to achieve full helicopter responsiveness. A plurality of bladeletts may be positioned near the outer periphery of the rotor head. When they are moved into the airstream, passing air impacts the bladeletts exerting a pressure, causing rotational movement of the rotor blade assembly.

    摘要: The invention relates to a blade (3) for a turbomachine, in particular for a rotor (2) of a helicopter, comprising a main section (5) that is designed to create a flow in the surrounding medium and that extends from a hub section (4) to a blade tip region (7). An end piece (6) for influencing eddy formation is provided in the blade tip region (7). To achieve a substantial noise reduction, the end piece (6) is designed as a rounded flow body comprising at least one groove (13a, 13b, 13c; 13d, 13e, 13f) originating in the transition region (12) between the body and the main section (5), substantially in the direction of the blade axis (8) and curving towards the trailing edge (11) of the blade (3).
