Abstract

FUSÍVEL. A invenção refere-se a um fusível (4) para um projétil giratório, incluindo um suporte de percussor (14) móvel em torno de um eixo de balancim (15) perpendicular ao eixo de simetria (A) do fusível, um suporte de espoleta (60) giratório em torno de um eixo de rotação paralelo ao eixo de simetria e um dispositivo de autodestruição (7). Este último inclui um mecanismo de SD (20) usando a aceleração linear do projétil na partida do disparo para armazenar energia cinética axial, e um mecanismo de segurança (30) usando os efeitos centrífugos do projétil durante o voo para armazenar energia cinética radial. Os dois mecanismos (20, 30) cooperam entre si, e com o suporte de percussor e o suporte de espoleta para gerar as diferentes posições de armazenamento antes do disparo, intermediária na saída do tiro, engatilhada durante o voo e de autodestruição ao final do voo, garantindo a máxima segurança do projétil na posição de armazenamento e a máxima capacidade de resposta do projétil independentemente do cenário encontrado durante o disparo balístico.
