Abstract
Embodiments of the present invention include a method for preparing and applying a slurry mixture to a bridge wire initiator which involves a slurry mixture that is relatively safer for a user to handle and in which the method is relatively less complex and shorter in duration for a user to prepare and apply the slurry mixture to the bridge wire initiator.
Claims20
A method of forming an initiator, the method comprising:
- placing an energetic powder in a container;
- adding a solvent to the container and mixing the solvent and energetic powder to form a slurry mixture;
- filtering the slurry mixture;
- placing the filtered slurry mixture in a transfer tube;
- applying slurry mixture to a bridge wire;
- and
- drying the slurry mixture applied to the bridge wire.
4 more elements
A system for applying a slurry mixture to a bridge wire of an initiator, the system comprising:
- a container sized to receive an energetic powder and solvent;
- a mixer operably coupled to the container to mix the energetic powder and solvent to form a slurry mixture;
- a screen disposed to receive the slurry mixture from the mixer;
- a transfer tube operably disposed to receive the slurry mixture from the screen;
- and
- a needle operably coupled to the transfer tube, the needle having an end a predetermined distance from the bridge wire.
3 more elements
A method of forming an initiator, the method comprising:
- placing an energetic powder in a container;
- adding a solvent to the container;
- performing a first mixing of the solvent and energetic powder to form a slurry mixture;
- performing a second mixing of the slurry mixture with a gyrating-type mixer;
- filtering the slurry mixture from the second mixing;
- determining the viscosity of the filtered slurry mixture;
- adjusting the viscosity of the filtered slurry mixture when the viscosity is less than 300 cP or more than 800 cP;
- placing a portion of the filtered slurry mixture in a dispensing syringe;
- applying the portion of the slurry mixture to a bridge wire;
- and
- drying the slurry mixture applied to the bridge wire.
