Abstract
Se describe un alabe de rotor para un motor de turbina de gases que incluye una region de punta que facilita la reduccion de las temperaturas de operacion del alabe de rotor; la region de punta incluye una primera pared de punta y una segunda pared de punta que se extiende radialmente hacia fuera desde una placa de punta de un plano aerodinamico; las paredes de punta se extienden de un borde de ataque adyacente del plano aerodinamico para conectarse en un borde de escape del plano aerodinamico, una muesca queda definida entre la primera y la segunda paredes de punta en el borde de ataque del plano aerodinamico; por lo menos una porcion de la segunda pared de punta esta ahuecada para definir un anaquel de punta.
