Stemmed blade for a flow-straightening stage of a turboshaft engine and method of fixing said blade

A stemmed blade for flow-straightener blading of a gas turbine engine includes at least one shank at the head of the blade forming a stem for use in fixing the blade. The shank has a notched portion situated adjacent the head of the blade and an end portion separated from the notched portion by a zone of lower tensile strength. Fixing of the blade to the engine casing is carried out by fitting the blade in position with the shank projecting radially outwards through a hole in the casing and then crimping a bush on to the notched portion of the shank using a suitable crimping tool which exerts a compressive force on the bush while exerting a traction force on the end of the shank until the zone of lower tensile strength breaks.
