Abstract
In a weapon subject to linear acceleration and spin, including a detonator and an explosive charge, the safing and arming device comprising a housing, a setback spring configuration restraining a ribbon spiral unwinder, and a detonator-enabling circuit which provides a fail safe for the omission of the safing and arming device from the fuze assembly.
Claims28
A control system for a projectile, including in combination:
- antenna means;
- electronic assembly means coupled to the antenna means;
- a battery coupled to the electronic assembly means;
- safing and arming means coupled to the electronic assembly means;
- the safing and arming means having a housing;
- a barrier forming an obstruction between a detonator and a detonator booster, the barrier being completely removable from between the detonator and the detonator booster under the action of a spin on the barrier;
- locking means which lock the barrier in a position forming the obstruction until released, the locking means including a spring means operating to release the barrier;
- timing means which trigger the release of the barrier at a predetermined time after the initiation of an acceleration;
- and restraining means which disengage the locking means on the acceleration;
- the detonator coupled to the safing and arming means;
- and
- the detonator booster coupled to the detonator.
A weapon subject to an acceleration and a spin about a spin axis, the weapon including a detonator and an explosive charge and comprising:
- a housing;
- a barrier forming an obstruction in line along the spin axis between the detonator and the charge, the barrier being completely removable from between the detonator and the charge under the action of the spin on the barrier;
- locking means which locks the barrier in a position forming the obstruction until the barrier is released, the locking means including spring means operating to release the barrier;
- timing means which triggers the release of the locking means at a predetermined time after the initiation of the acceleration;
- and
- restraining means which disengages the locking means in response to the acceleration.
A safing and arming device subject to an acceleration and a spin about a spin axis, the safing and arming device including a detonator and an explosive charge and comprising:
- a housing;
- a barrier forming an obstruction in line along the spin axis between the detonator and the charge, the barrier being completely removable from between the detonator and the charge under the action of the spin on the barrier;
- locking means which locks the barrier in a position forming the obstruction until the barrier is released, the locking means including spring means operating to release the barrier;
- timing means which triggers the release of the barrier at a predetermined time after the initiation of the acceleration;
- and
- restraining means which disengages the locking means in response to the acceleration.
