摘要:
The present invention describes methods for programming trigger time of a projectile (60) based on remaining flight time to a target (P) after the projectile (60) is airborne. The actual muzzle (Vo) and flight speeds (V1, V2, etc.) are independently determined and compared to those used by the ballistic computer (30), and a better estimate of trigger time is accordingly used to activate detonation of the projectile (60). In one embodiment, a Kalman algorithm is used to provide a better estimate of the projectile's flight speeds obtained by independent methods to provide the better estimate of the trigger time.
摘要:
A system, apparatus, and method for detonating a projectile which includes receiving data by a microprocessor located in the projectile from an external ballistic computer. Calibrating a low frequency oscillator located in the projectile using an internal precision reference oscillator also located in the projectile that can withstand launch accelerations of tens of thousands of g's. Powering off the reference oscillator when calibration is complete to save energy and transmitting a detonation signal from the microprocessor to a detonation circuit located in the projectile.

摘要:
A projectile, (Cruise Munition Detonator Projectile or CMDP), can be fired from a tank, modified grenade launcher or gun using a laser range finder, radar or manual input (dialer or keypad) range selector. The CMDP will prevent, neutralize and eliminate enemy close infighting. The CMDP can defend aircraft against SAM, shoulder launched missiles, and air-to-air missiles. The CMDP will travel a predetermined programmed distance and detonate in front of or behind, over or beside, or in the mist of a target. The CMDP allows small forces to strategically neutralize larger forces with devastating effect. The CMDP is a force multiplier and an anti-personnel weapon.

A projectile comprises a payload portion and an airburst fuze mounted on a rear of the projectile and explosively connected to the payload portion. The airburst fuze comprises 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; and 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.
摘要:
A synchronous or synergeticly timed fuse is installed into ordnance (bombs, artillery shells, depth charges etc.), the ordnance is delivered to a target area and a simultaneous (synchronous), or a synergetic (not neccessarily synchronous yet the energies add together to be greater than their individual parts), explosion event occurs. This explosion event can be enhanced by the shape the ordnance is configured in (a shaped charge on the order of meters or kilometers).

A detonation timing apparatus and method of determining a detonation time is disclosed. The detonation timing apparatus comprises an initiation sensor, at least one impact sensor, and at least one controller. The at least one controller may be configured for sensing an initiation event associated with the initiation sensor and sensing an impact event associated with the at least one impact sensor. The at least one controller is further configured for determining an impact velocity estimate proportional to a temporal difference between the initiation event and the impact event, using the impact velocity estimate to determine the detonation delay, and generating the detonation event at the detonation delay after the impact event. The timing apparatus and method of determining a detonation time may be incorporated in a fuze, which may be incorporated in an explosive projectile.
