DMS End Burner ignitor installation

[Buckeye]

I cracked open an Aerotech H13ST DMS motor. The igniter inserts only about 1.25" into the nozzle before stopping against the solid propellant. I assume this is how end burners work (like an Estes BP motor), but I am just double checking. There is no core of any kind in the propellant for the ignitor to go through?

Yup. That’s exactly how it should work

Here's a cutaway drawing of the H13, which shows how deep the core is.

Thanks all. The dimensions just about add up to my 1.25" measurement.

I assume this is how end burners work (like an Estes BP motor),

If I remember correctly they call this type of motor a cored end burner.
