Device and method for producing a blade for a turbine and blade produced according to this method

   
   

A device and a method are for producing a blade including two outer walls and at least one cavity between the outer walls, for a turbine. An outer mould and several cores are used in forming the outer walls and the at least one cavity of the blade. At least one of the cavities is divided into two channels by a middle segment. One channel is located between the first outer wall and the middle segment, while the other channel is located between the middle segment and the second outer wall. Two cores which are separate from each other are used accordingly. This provides a simple and economical means of reducing the thickness of the outer wall.

Um dispositivo e um método são produzindo uma lâmina including duas paredes exteriores e ao menos uma cavidade entre as paredes exteriores, para uma turbina. Um molde exterior e diversos núcleos são usados em dar forma às paredes exteriores e à ao menos uma cavidade da lâmina. Ao menos uma das cavidades é dividido em duas canaletas por um segmento médio. Uma canaleta está posicionada entre a primeira parede exterior e o segmento médio, quando a outra canaleta for posicionada entre o segmento médio e a segunda parede exterior. Dois núcleos que são separados de se são usados conformemente. Isto fornece uns meios simples e econômicos de reduzir a espessura da parede exterior.
