Base mounted airburst fuze for projectile

A projectile, comprising

• payload portion for housing a payload;
• and
• an airburst fuze mounted on a rear of the projectile and explosively connected to the payload portion;
• the airburst fuze comprising:
• an arming and firing electrical circuit including a setback generator;
• a slider that is movable from a safe position to an armed position, the slider including a detonator attached thereto;
• a setback lock and a spin lock that lock the slider in the safe position and, in response to a setback acceleration and a spin rate, respectively, unlock the slider;
• an actuator that moves the slider to the armed position in response to a first input from the arming and firing electrical circuit;
• wherein a second input from the arming and firing circuit activates the detonator when the slider is in the armed position;
• wherein the arming and firing electrical circuit further includes an arming circuit for providing a time to arm a safety and arming device, and a firing circuit for providing a fuze functioning time;
• wherein the arming circuit provides a first time delay;
• wherein the firing circuit provides a second time delay that is longer than the first time delay;
• wherein the setback generator provides power to a first capacitor for powering the arming circuit, and further provides power to a second capacitor for powering the firing circuit;
• wherein the first time delay is accomplished as the first capacitor discharges through the actuator, causing the actuator to function for arming the airburst fuze;
• wherein the second time delay is accomplished as the second capacitor discharges through the detonator, causing the actuator to causing the payload to detonate during flight, when the slider is in the armed position.
