Safe and arm device and explosive device incorporating same

An explosive device, comprising:

• a delay housing movable from a safe position to an arm position;
• a target sensor protruding from the explosive device and connected to move the delay housing from the safe position toward the arm position under an applied force;
• and
• a restraining element positioning the delay housing at the safe position, the restraining element breakable under the applied force;
• wherein a direction of motion of the target sensor under the applied force includes a first displacement component along an axial direction of the explosive device;
• and
• wherein the direction of motion includes a second displacement component along a radial direction of the explosive device.

An explosive device, comprising:

• a delay housing movable from a safe position to an arm position;
• a target sensor protruding from the explosive device and connected to move the delay housing from the safe position toward the arm position under an applied force;
• a restraining element positioning the delay housing at the safe position, the restraining element breakable under the applied force;
• and
• a safing channel in an outer surface of the explosive device, the safing channel adapted to receive a target sensor of an adjacent explosive device when the delay housing of the adjacent explosive device is in the first position.

An explosive train for an explosive device, including a casing comprising:

• a primer activated by contact with a firing pin;
• a delay housing movable from a safe position to an arm position, wherein the delay housing includes a deflagration-to-detonation material that is initiated by the activated primer;
• a target sensor protruding radially through the casing of the explosive device and connected to move the delay housing from the safe position toward the arm position under a force applied to the target sensor;
• and
• a secondary explosive, wherein the secondary explosive is detonated by the initiated delay housing.

An explosive device, comprising:

• a casing;
• a delay housing movable from a safe position to an arm position;
• a target sensor protruding through the casing of the explosive device and connected to move the delay housing from the safe position toward the arm position under an applied force;
• a restraining element positioning the delay housing at the safe position, the restraining element breakable under the applied force;
• a nose protruding trigger mechanism including a primary explosive or a booster explosive;
• and a secondary explosive,
• wherein the trigger mechanism is separate from the target sensor and configured to ignite the primary explosive or the booster explosive, and
• wherein the force of the ignition of the primary explosive or the booster explosive is configured to detonate the secondary explosive when the delay housing is in the armed position and configured to not detonate the secondary explosive when the delay housing is in the safe position.
