|Tykeanaut||I would like to know if anyone knows what this quick release pin's exact use was? I am pretty sure it was a ground support equipment (GSE) item.|
|mikej||It was used to reduce the shock when the Saturn V's holddown arms released the vehicle at launch.|
Usually they're referred to as "soft", "slow" or "controlled" release pins or rods (rather than "quick").
There's more discussion in this regard in this thread.
|SpaceAholic||Mike, this is a manually engaged/manually retracted quick release pin... would be surprised if its intended application is as described in the referenced thread.|
|GACspaceguy||Not sure about the Saturn V application but this is a common "pip" pin used in aviation. Typically there is a "Remove Before Flight " streamer attached to it and is used in lock out areas like the landing gear and/or covers and support equipment.|
|David Carey||Fred's PIP explanation makes the most sense to me so far and to your original comment I associate quick-release fasteners of most any kind to ground versus flight. |
I can make out some of the writing on the card -
"An original Quick Release Pin designed for the mighty Saturn V Moon Rocket by the Boeing Company at the Michoud facility in New Orleans Louisiana where the Saturn V F1 engines were (????) under contract with NASA"
But the contract numbers and other caption may help the group (or a better picture).
|Tykeanaut||Thanks all for your input.|
It's spare parts #NAS1335S2S24D, Contract # NAS8-5608.
It was apparently used in the testing of the Saturn V F-1 first stage engines under contact with NASA.
|GACspaceguy||Okay, the basic part number is NAS1335 and the "NAS" is National Aerospace Standard, therefore it is a common quick release pin but for my 30+ years around the aircraft flight line we have always called them pip pins (due to the pip or retractable ball pin at the end of the shank. |
While it may have been used on the Saturn V it was not specifically designed for that vehicle as it is a standard aerospace part.
