| 摘要 | The distance traversed by a spin-stabilized projectile is determined by a pendulum attached inside the fuze of the projectile so that each complete swing of the pendulum is equal or proportional to one complete revolution of the spinning shell. The distance traversed by the projectile is determined from reading of the number of complete cycles (frequency) made by the pendulum which, in turn, is equal to the number of revolutions of the spinning shell. | ||||||
| 权利要求 | 1. A device for determining the distance traversed by a spinstabilized projectile having a spinning shell, which device comprises, in combination, a fuze element coaxially mounted in said projectile, pendulum means attached to said fuze element and adapted to oscillate therein in response to the centrifugal force generated by said spinning shell so that the frequency of cycles of said pendulum means is proportional to the revolutions of said spinning shell of said projectile, and means for determining the frequency of oscillation of said pendulum means. 2. A device as in claim 1 wherein said pendulum comprises a swing-arm having two ends, one end being pivotably attached to the center of said fuze element and the other end being attached to a disc- or ball-like object. 2. associating said pendulum means with a counting means for determining the frequency of oscillation of said pendulum means and adapted to activate said fuze element at a predetermined number of oscillations of said pendulum means; 3. connecting said counting means to a setting means; and 3. A device as in claim 1 wherein the means for determining the frequency of oscillation of said pendulum means comprises a photoelectric cell. 4. A device as in claim 1, wherein the means for determining the frequency of oscillation of said pendulum means comprises a ratchet or escape wheel. 4. adjusting the setting means to cause activation of said fuze element at a predetermined number of oscillations of said pendulum means corresponding to the preset distance of traverse of said projectile. 5. A device as in claim 1, wherein the pendulum is a double ended pendulum. 6. A method for presetting the distance of traverse of a spin-stabilized projectile having a spinning shell and a fuze element which method comprises: |
