Abstract

A multi-support tail joint of working blade of turbine with secured contact at all supports has teeth of slot of tail element and teeth of knob of disc rim connected at support surfaces and forming platforms of contact at marks of radii of fillet. Center of radius of tail element slot fillet and center of disc rim knob tooth fillet that determine site of contact are placed at one normal with respect to support surfaces and thus form arcs of fillets of teeth, bringing the contact site to line in the peripheral direction of turbine.
