Abstract

PROJéTIL DE EXPANSãO MONOBLOCO ISENTO DE CHUMBO E RESPECTIVO PROCESSO DE FABRICAçãO. A presente invenção está relacionada a um projétil feito de uma única peça sólida de metal deformável, que não contém chumbo ou materias tóxicos, é facilmete deformável porém não sofre fragmentação em um ambiente mole com uma alta taxa de transferência de energia, e apresenta um alto nível de solidez em alvos rígidos, retendo a maior parte ou o total de sua massa inicial ao penetrar estes alvos. Os referidos objetivos são alcançados construindo-se um projétil monobloco sólido com uma cavidade no eixo longitudinal que se abre na direção da extremidade dianteira do projétil. O método de construção abrange uma seqüência de operações simples: corte de uma matriz cilíndrica de material mole, moldagem de uma cavidade centrada no eixo longitudinal, e moldagem de uma forma ogival ou cónica, com pre-cortes externos para favorecer uma deformação homogênea. A presente invenção se aplica a munição para qualquer arma de mão, rifle ou espingarda; quando utilizada em armas com cano de alma lisa, a estabiliadade essencial do projétil é obtida através do posicionamento do centro de gravidade adiante do centro aerodiâmico.LEAD-FREE MONOBLOCK EXPANSION PROJECT AND ITS MANUFACTURING PROCESS. The present invention relates to a projectile made from a single solid piece of deformable metal, which contains no lead or toxic materials, is easily deformable but does not fragment in a soft environment with a high energy transfer rate, and has a high solidity level on rigid targets, retaining most or all of their initial mass when penetrating these targets. Said objectives are achieved by constructing a solid one-piece projectile with a longitudinal axis cavity that opens toward the front end of the projectile. The construction method comprises a simple sequence of operations: cutting a cylindrical matrix of soft material, molding a cavity centered on the longitudinal axis, and molding in an ogival or conical shape, with external pre-cuts to promote homogeneous deformation. The present invention applies to ammunition for any handgun, rifle or shotgun; When used on smooth-barreled weapons, the essential stability of the projectile is achieved by positioning the center of gravity ahead of the aerodynamic center.
