 24mm Motor system
|
My 24mm motors are
basically the same as the 18mm version only bigger. I had the
supplies to build them with for over a year before I actually made the
first motor. I received a request in late 2006 from a customer for two
motors. He wanted one to hold a 40mm fuel load, and one to take an
80 mm fuel load. I was so pleased with them after I made them, that I
decided to make some for myself. They are
turned from 6061 aluminum This system was developed to be used with sugar propellants. The motor above holds a 140mm fuel load that weighs around 62.5 grams. It has a .203" nozzle and is perfect for a C-slot or 4 Bates grains. The nozzle size will vary depending upon grain geometry.
With a c-slot grain this
motor static tested as a strong F-50. An Excel file of the test is
available here.
