Yes.....and...
but a 75lb rocket with 3 of the PML small size holding the Av-bay in payload, surely gets a heck of a wallop from recovery.
Just last month I had a 3 in. rocket CATO under full head of steam. Main deployed at 3 seconds snapped the 9/16 tubular nylon off eyebolt & didn't faze the rivets. This was apogee side where force was brutal and nothing to hold stuff together except the rivets.
Even with the use OP has stated, the forces you guys are discussing are from recovery being attached to top side of motor retention.
The forces should be carried through eyebolt.....rods...motor and thrust ring/rear closure. Little or none directly on rivet's except from BP.
I have had 7 gram BP charges on the 7.5 inch, no vet band to stop forward movement of bay.
They even held when chute failure caused a direct hit on av-bay[no vent band] upon free-fall landing. Just 3.
Am I missing something or not following correctly?
My experience has been good, I cannot account for others & their use of them. I feel totally confident & did use them on a 54minimum, making my own retention similar to Aero-pacs....just a coupler section, BP with eye-bolt running through to motor. Rivets from airframe, through coupler, to hold in place.
Works identical at fraction of cost. This one was a 98.
