A compressor aerofoil rotor blade for a turbine engine includes: a root portion spaced apart from a tip portion by a main body portion. The main body portion is defined by a suction surface wall having a suction surface and a pressure surface wall having a pressure surface. The suction surface wall and the pressure surface wall meet at a leading edge and a trailing edge. The tip portion comprises a shoulder provided on the pressure surface wall. A tip wall extends from the aerofoil leading edge to the aerofoil trailing edge. A transition region of the pressure surface wall tapers from the shoulder in a direction towards the tip wall. The tip wall includes a squealer defined by a first tip wall region which extends from the trailing edge to a winglet.

Compressor aerofoil

A compressor aerofoil for a turbine engine includes a tip portion with a tip wall which extends from the aerofoil leading edge to the aerofoil trailing edge. The tip wall defines a squealer which extends between the leading edge the trailing edge. A shoulder is provided on one of the suction surface wall or pressure surface wall which extends between the leading edge and the trailing. A transition region tapers from the shoulder in a direction towards the tip wall. The other of the suction surface wall or pressure surface wall extends towards the tip wall.
