So I had heard that Aerotech engines were a bit complex in all their permutations. For example, this old thread highlights all the different sizes and spacers and such.
So I have the RMS-29/360, and an H180W-14A for my engine (what does the "A" stand for, btw?), and the "Reload Adapter System" (RAS).
The motor comes with the aluminum motor case, a standard motor forward closure, a forward seal disc, and a motor aft closure,
The RAS comes with two spacers, a floating forward closure, and a retaining ring.
For a normal 360 size motor one uses the forward seal disk (optional, depends on motor?) and the forward closure.
For a shorter motor (in my case, a "240"), one uses the floating forward closure instead of the standard one. So I'd put the delay charge (with appropriate o-ring) in the floating closure, and the ejection charge with cap on the forward end of that floating closure, then put it in the casing, then add the appropriate number (one or two) spacers, and then the floating forward closure. Is this correct?
The picture shows the aft closure, the casing, and the (optional) forward disk seal (the common parts) in the vertical middle of the picture, with the two foreward options above and below. Below is shown the standard aft closure for full 360 size motors. Above is the floating forward closure, two extensions, and the retaining ring. For my L1 motor (shown) the upper arrangment is what I want.
Aerotech's instructions were apparently written by engineers. As an engineer myself, let me clarify that is not a compliment. Why not show an exploded diagram in the instructions? Grrrr.
But to help ensure I don't CATO on my L1 flight, do I have the correct parts laid out?
Thanks!
