Rocket delay apparatuses, systems and methods
View Patent ↗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.
1. A rocket motor delay modification process comprising:
providing a modifiable delay having an ejection side and propellant side opposite the ejection side, the delay comprising delay material configured to be reduce by drilling;
modifying a delay time by reducing the delay material from the ejection side of the modifiable delay:
the modifying including drilling the delay material through an ejection opening in a bulkhead in which the delay is disposed, the ejection opening being opposite a propellant side of the bulkhead, the ejection opening being markedly smaller than the propellant side of the bulkhead for controlled ejection gas transmission therethrough;
the modifying including drilling by a tool having two sides each having a respective discrete well of two discrete well sizes to achieve two alternative delay times; the two discrete well sizes having internal structure configured to provide for engaging the ejection side of the rocket bulkhead at discrete depths.
2. A rocket motor delay modification process according to claim 1 the process modifying the delay time of one or more of more of single use, limited re-use and reloadable motors.
3. A rocket motor delay modification process according to claim 1 further comprising:
engaging a delay modification apparatus with an ejection end of a rocket bulkhead having the modifiable delay comprising the delay material therein;
removing the delay material from the delay to effectuate a discrete delay time.
4. A process according to claim 3 further including:
selecting a desired alternative delay time for the apparatus.
5. A process according to claim 3 further including:
flipping the delay apparatus body to achieve an alternative delay time.
6. A process according to claim 3 further including:
introducing a spacer between the delay apparatus body and the knob to achieve an alternative delay time.
7. A process of claim 3 for use with one or more of single use, limited re-use and reload able motors.
