Abstract:
A blade for a turbomachine, in particular for a rotor of a helicopter. A main section is designed to create a flow in the surrounding medium and extends from a hub section to a blade tip region. An end piece for influencing eddy formation in the blade tip region. To achieve a substantial noise reduction, the end piece is designed as a rounded flow body comprising at least one groove originating in the transition region between the body and the main section, substantially in the direction of the blade axis and curving towards the trailing edge of the blade.
