                                     18mm Motor system with delay grain (made by user)

My 18mm motors. They are turned from 6061 aluminum
stock with an integral thrust ring. They incorporate a delay header and graphite nozzle secured with snap-rings.

This system was developed to be used with sugar propellants. The motor above has a .125" nozzle and is perfect for c-slot and moon burner grains. The nozzle can be enlarged if desired for use with other grain geometries.

With a moonburner grain this motor static tested as a full D-18. An Excel file of the test is available here.
