Blade for a rotor
First Claim
1. A blade for a rotor, the blade having an aerofoil surface comprising pressure and suction sides extending between a leading edge and a trailing edge of the aerofoil surface, and having a squealer tip comprising a peripheral wall surrounding a cavity which is open at a radial end of the blade and at the trailing edge of the blade, wherein the peripheral wall comprises at least one first region which extends radially and has an outer surface which is a continuation of the aerofoil surface, and at least one second region which is inclined outwardly of the cavity with respect to the radial direction and has an outer surface which extends obliquely outwardly of the blade from the aerofoil surface along part of at least one of the pressure side and suction side.

Abstract
A blade for a rotor, such as a turbine rotor of a gas turbine engine, has a squealer tip comprising a peripheral wall which defines a cavity. A first region of the peripheral wall extends radially, with its outer surface forming a continuation of the adjacent aerofoil surface of the blade. A second region extends obliquely with respect to the radial direction and the adjacent part of the aerofoil surface. The second region defines a winglet, and serves to increase the width of the chamber towards the trailing edge of the blade.
