Abstract
A spin-stabilized projectile has a projectile body and a guide band being circumferentially mounted on an outer face of the projectile body. The guide band includes a plurality of axially adjoining partial guide bands. One of the partial guide bands is a first partial guide band made of copper, a copper alloy or another soft metal. One of the partial guide bands is a second partial guide band made of soft iron and axially adjoining the first partial guide band. A total axial length of all second partial guide bands is between 5% and 50% of the total axial length of the guide band.
Claims14
A spin-stabilized projectile having a longitudinal projectile axis, a projectile body and a guide band being circumferentially mounted on an outer face of said projectile body;
- said guide band comprising a plurality of axially adjoining partial guide bands;
- one of said partial guide bands being a first partial guide band made of a material selected from the group consisting of copper, a copper alloy and a soft metal;
- and one of said partial guide bands being a second partial guide band made of soft iron and axially adjoining said first partial guide band;
- a total axial length of all second partial guide bands being between 5% and 50% of a total axial length of said guide band.
A method of mounting a guide band on a projectile body of a spin-stabilized projectile;
- said guide band comprising a plurality of partial guide bands;
- one of said partial guide bands being a first partial guide band made of a material selected from the group consisting of copper, a copper alloy and a soft metal;
- and one of said partial guide bands being a second partial guide band made of soft iron and axially adjoining said first partial guide band;
- a total axial length of all second partial guide bands being between 5% and 50% of the total axial length of said guide band;
- the method comprising the consecutive steps of connecting together the first and second partial guide bands in axial alignment to one another to form a one-piece unit constituting said guide band;
- and securing said guide band to said projectile body.
A method of mounting a guide band on a projectile body of a spin-stabilized projectile;
- said guide band comprising a plurality of partial guide bands;
- one of said partial guide bands being a first partial guide band made of a material selected from the group consisting of copper, a copper alloy and a soft metal;
