Abstract

Núcleo mecánico desmontable y procedimiento de instalación. La presente invención se refiere.a un núcleo mecánico desmontable (1) que comprende una contra-forma (2) fijada sobre un mandril central (3, 8), debiendo poder ser manipulados a distancia y con total seguridad los elementos de la contra-forma. Estos elementos (10, 11, ...) de contra-forma están ligados y fijados sobre el mandril central (3, 8) mediante unos dispositivos (6) de anclaje de varillas. La presente invención se refiere también a unos procedimientos de ensamblaje y de desensamblaje de dicho núcleo. Este núcleo mecánico desmontable se utiliza fundamentalmente para el modelado de la cavidad interna de carga de propergol sólido.
