发明名称 BLADE FOR A TURBOMACHINE
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).
