Met Scott a couple of times. Stopped off in Peoria to try to show us how to characterize motors. Was a week or so before Steve Eve's Saturn 5 launch and was passing through. (Well heck, we paid him!) At the time he was just starting to work for Jeff Taylor (who originally owned Loki) and we really had a "blast". We really should'a stuck with a well characterized propellant to do test stand "instructional" runs but noooooo.................... Scott came up with this mix called "Baby S**t" that required us to scrounge around enough magnesium to make the mix. Well, I dumped a bunch of "my Mg" into the pot and still regret it. (I did recover with new supplies) and thankfully, Scott hasn't offered this as a Loki propellent choice as far as I know. Looks like light brown poop and all of the motors I've bought from him are far from that color.
Our group had a very good vacuum arrangement and we sucked the daylights out of it. Measured the weight of "each an' every" grain for the two grain 38mm test motors.
Scott showed us how to calibrate the load cell and "I POINTED OUT" in a moronic fashion that if one drops out the un-needed channels in the Dataq (free at the time software)
that the sampling rate went up! I recall he seemed impressed.
Well, we blew up his only loadcell that he brought to our "PAID TEACHING AND INDOCTRINATION SESSION" but none-the-less, he left us with the pr'fessors take on characterizing. Unfortunately, several mishaps occurred and our local club hasn't been able to proceed with characterization of propellants.
Well the bottom line is I've emailed Scott about the 29's in the past and heck he dug out some forward 29mm closures Jeff Taylor left for him and were unlisted on the site. I bought a few of them to have enough for the two cases I have. Pictures below:
I have another of the blue anodized "29's" in the other room. The three on the right are nothing to do with Loki but are Aluminum 24mm motors that conceivably can achieve an H impulse and I fired one with Research propellant that was an "H" impluse. The graphite nozzle was "toasted" to single use ( I saved it) and the aft snap ring was bowed out to the "nth" degree. A second more and the motor would've blown.
The grain configuration was really young man "stupid" and suffice it to say I had the top grain with a .125" core, did ultra-thin Kynar wire for an igniter.
This 24mm motor ran right up to the edge and didn't blow but a few fractions of a second more and the nozzle would have blown. The aft snap ring
was bowed out and the nozzle was incredibly "crumbly". The blue Loki cases on the left probably could do an I-300 safely with a well designed grain
configuration that is best left to an obsessive compulsive type who has an unlimited source of cases and nozzles.
I can appreciate not doing 29mm grains in a one man operation with the tediousness it takes to contsruct them. Best left to the "Ex" folks out there who
are adventurous. Kurt
