Hopefully I can get a quick answer here, I need to know for tomorrow (July 4th).
- Can Aerotech delay grains be shortened by drilling a shallow hole, as I've seen done with other manufacturers' delays?
- If the answer to #1 is yes, how many millimeters, 64ths of an inch, or whatever of hole depth are required for each second to be taken off the delay?
- Would the drilled side of the delay grain face the propellant or the ejection charge?
