Horizontal/Vertical Test Stand
Shown with a 3" x 32" Solid Motor Installed
The motor slides back and forth under thrust on 4 custom Delrin sliders.
Since the load cell only deflects a couple of thousandth inches, the
sliders need only move an 1/8" or so.
The angled braces are each rated for 1,200 pounds force each.
That coupled with the corner bracing the stand could probably take
2,500 pounds force, we recommend no more than 1500 LB-F.
Here the stand is shown with a smaller 38mm motor, it looks pretty
small in the test stand. The 3" tubing clamps can be stowed
on the unistrut out of the blast radius when not in use. 4"
and 54mm clamps can be stored in a similar fashion. In order to make
the 38mm motor mate with the load cell the plate the cell is mounted
on has to be loosened and positioned. Simply drop the plate
about 1" then retighten the 2 bolts holding it in place.
Most of the bolts on the stand are the same so only a crescent wrench
is needed to make adjustments and to change motor configurations.
The tubing clamp nuts are installed finger tight only. Originally
the stand was designed for vertical firing of small liquid rocket
motors. The 12 x 12 inch foot print and lineal footage of strut
available for mounting hardware makes it ideal for this application.
A couple of guy wires to steady the stand and two stakes should secure
it in place nicely.
Laying the stand down you have a terrific horizontal test stand that
is robust, easily adjustable, and will take any diameter motor with
the addition of the appropriate diameter tubing clamp.
Total weight of the stand is about 40 pounds, figure 45 pounds shipped.
