Abstract: During the manufacturing process for turbine blades and vanes, among other hollow articles, the hollow cavities can become contaminated. Removal of the contaminants is a tedious, time consuming process which commonly results in component rework or rejection. Introducing a foam filler into the hollow cavities, prior to manufacturing, prevents contamination; enhancing manufacturing efficiency and component integrity.

Abstract: UN METODO PARA EXCLUIR CONTAMINANTES DE ARTICULOS HUECOS DURANTE LA FABRICACION. DURANTE EL PROCESO DE FABRICACION DE PALETAS Y ASPAS DE TURBINA, ENTRE OTROS ARTICULOS HUECOS, PUEDEN CONTAMINARSE LAS CAVIDADES HUECAS. LA ELIMINACION DE LOS CONTAMINANTES ES UN PROCESO MOLESTO Y QUE CONSUME TIEMPO QUE RESULTA COMUNMENTE EN LA REELABORACION DEL COMPONENTE O EL RECHAZO. LA INTRODUCCION DE RELLENO DE ESPUMA EN LAS CAVIDADES HUECAS, ANTES DE LA FABRICACION, IMPIDE LA CONTAMINACION; FAVORECIENDO LA EFICACIA DE LA FABRICACION Y LA INTEGRIDAD DEL COMPONENTE.

Abstract: During the manufacturing process for turbine blades and vanes, among other hollow articles, the hollow cavities can become contaminated. Removal of the contaminants is a tedious, time consuming process which commonly results in component rework or rejection. Introducing a polymeric foam filler into the hollow cavities, prior to manufacturing, prevents contamination; enhancing manufacturing, efficiency and component integrity. Filling is by gravity via a boot (60) or negative pressure infiltration. Subsequent removal is by solvent or heat. The blade or vane can be encapsulated using a mould or moulding paper.
