Rotor blades for turbine engines

A blade tip (38) of a turbine rotor blade (18) for a gas turbine engine, the turbine rotor blade (18) including an airfoil (24) and a root portion (36) for mounting the airfoil (24) along a radial axis to a rotor disk (16) inboard of a turbine shroud (20), a pressure sidewall (28) and a suction side...

Beschreibung
Zusammenfassung:	A blade tip (38) of a turbine rotor blade (18) for a gas turbine engine, the turbine rotor blade (18) including an airfoil (24) and a root portion (36) for mounting the airfoil (24) along a radial axis to a rotor disk (16) inboard of a turbine shroud (20), a pressure sidewall (28) and a suction sidewall (30) that join together at a leading edge (32) and a trailing edge (34), the pressure sidewall (28) and suction sidewall (30) extending from the root portion (36) to the blade tip (38), and a squealer tip cavity (62) formed at the blade tip (38), the blade tip (38) including a trailing edge trench (72) originating at an aft end of the squealer tip cavity (62), wherein the trailing edge trench (72) generally extends toward the trailing edge (34) of the blade tip (38).
