US12474147 - Grounding sabot and methods of use

A sabot that includes a body configured to be partly received within a propellant chamber of a perf gun, and the body includes an interface configured to engage a projectile, a divider that defines part of the interface, an ignition pass through that extends through the divider, an ignition stack electrically connected to the ignition pass through, a ground terminal electrically connected to the ignition pass through, a deflector defined by the divider and having a cup-shaped configuration, and the deflector is configured to expand diametrically upon ignition of a propellant in the propellant chamber when the sabot is positioned within the propellant chamber, a gas valve configured and arranged to be actuated by expansion of the deflector, and a compensator positioned between the interface and the gas valve.

The patent describes a sabot designed for use in a perf gun, featuring a body that partially fits within the propellant chamber and includes various components such as an ignition pass through, a deflector, and a gas valve. Upon ignition of the propellant, the deflector expands to actuate the gas valve, enhancing the performance of the projectile.

Claim 1

1 . A sabot, comprising: a body configured to be partly received within a propellant chamber of a perf gun, and the body comprises an interface configured to engage a projectile; a divider that defines part of the interface; an ignition pass through that extends through the divider; an ignition stack electrically connected to the ignition pass through; a ground terminal electrically connected to the ignition pass through; a deflector defined by the divider and having a cup-shaped configuration, and the deflector is configured to expand diametrically upon ignition of a propellant in the propellant chamber when the sabot is positioned within the propellant chamber; a gas valve configured and arranged to be actuated by expansion of the deflector; and a compensator positioned between the interface and the gas valve. a body configured to be partly received within a propellant chamber of a perf gun, and the body comprises an interface configured to engage a projectile; a divider that defines part of the interface; an ignition pass through that extends through the divider; an ignition stack electrically connected to the ignition pass through; a ground terminal electrically connected to the ignition pass through; a deflector defined by the divider and having a cup-shaped configuration, and the deflector is configured to expand diametrically upon ignition of a propellant in the propellant chamber when the sabot is positioned within the propellant chamber; a gas valve configured and arranged to be actuated by expansion of the deflector; and a compensator positioned between the interface and the gas valve.
