Abstract

Delay tools, systems and methods for achieving a selection of alternative delay times, a tool of which including a body, a drill bit operable relative to the body and a knob operably connected to the drill bit, and operably disposed relative to the body for engagement of the body with a rocket motor bulkhead and the drill both relative to a delay to provide for achieving a selection of alternative delay times.

Claims (25)

1. A rocket motor system with a modifiable delay system including:

a rocket motor comprising a bulkhead and a delay disposed within the bulkhead to provide for achieving a selection of alternative delay times, and

a delay modification tool including

a body,

a drill bit operable relative to the body, and

a knob operably connected to the drill bit and operatively disposed relative to the body,

wherein the body, drill bit and knob of the delay modification tool are operatively configured for engagement of the body with the bulkhead of the rocket motor and engagement of the drill bit with the delay within the bulkhead;

wherein one or more of the following:

the body has two sides each having a respective discrete well of two discrete well sizes to achieve two alternative delay times;

the tool has two discrete well sizes having internal structure configured to provide for engaging a rocket bulkhead at discrete depths; or

the tool further includes a spacer to alter the delay achieved.

2. A rocket motor system with a modifiable delay system including:

a rocket motor comprising a bulkhead and a delay disposed within the bulkhead to provide for achieving a selection of alternative delay times, and

a delay modification tool including

a body,

a drill bit operable relative to the body, and

a knob operably connected to the drill bit and operatively disposed relative to the body,

wherein the body, drill bit and knob of the delay modification tool are operatively configured for engagement of the body with the bulkhead of the rocket motor and engagement of the drill bit with the delay within the bulkhead;

wherein the engagement of the drill bit relative to a delay disposed within the bulkhead provides for achieving a selection of alternative delay times and,

wherein one or more of:

the body has at least first and second sides each being alternatively engageable with the rocket motor bulkhead, each providing for alternative delay times;

the body has at least first and second sides each having a respective first and second well of two discrete first and second well sizes to achieve two alternative delay times;

the body is substantially cylindrical and the body has at least first and second sides each of the first and second sides having a respective first and second well of two discrete first and second well sizes each being alternatively engageable with the rocket motor bulkhead, each providing for alternative delay times;

further comprising a spacer to alter the delay to be achieved; or

further comprising a spacer to alter the delay to be achieved wherein the spacer is removably disposable between the body and the knob and is configured so that the knob will be unable to contact the body.
