Jason's Motor Porn Thread

If i remember correctly as APS was getting rolling Dunkel got a real job with Spaceport Florida and couldn't do the management/financial side of the operation.
Mike was always good to me. I was at the first Rockets for Schools in Sheboygan, He got me and girlfriend, now wife, to the front row of the show. They needed a truck to move the S Loki booster from the magazine, my GF had a Chevy El Camino so she got to go get it with a National Guard soldier to get through the road blocks. Pretty cool.

Yeah, I thought it was unusual that they seemed to come on strong based on ads in HPR, then nothing at all. To the extent anyone wishes to share, what happened to them?

He still owes me 54/3300 hardware I paid for and never received.

If anyone is interested I'll email them an old APS price list, basically a hardware/reload offering list.

That’s the one.

Thanks to Lowell for the price sheet!

First I've seen a Kosdon price list like this. Thanks for sharing Tony (and Lowell)!

My Original Kosdon 640 motor case. Purchased from Eric Gates. Complete with Playa dust. This has been moved over to the museum collection.

I ran across an old Enerjet motor while sorting out some old rocketry supplies at my university. Can anyone ID it? It has no designation on it, only the number 8.
Here's a link to photos of it. Also in there are some old packages of Centuri igniters.

That is an original Enerjet 8 from Irv Wait's Rocket Development Corp. Centuri later bought the rights to the Enerjet line and brought Irv to work on developing the Enerjet line for them. Is there anything showing in the ejection end opening? The first Enerjet 8s, an E class motor, had a delay setup on top where a fuse was wound around a tube and one end was bent in front of the exhaust.

Enerjet 8 in 1968 RDC catalog.

From a look down the nozzle at the grain geometry, it's a BATES type or core burner grain, and I can see at the top where the delay element is a small bent nail of sorts.
At the top end where the delay element and ejection charge would usually be, there's a shallow cavity. It appears that the top of the delay element is completely exposed, without any sort of ejection charge. I'm not sure if the top wood cap with a hole in it came with the motor, it looks like glued on Masonite. I can try to get a picture of the bottom and top of the delay element tomorrow.

Any chance of a larger scan full size?

ISP H128

Wow. How old is that?

from aerotech site

In 1985, Gary co-founded Industrial Solid Propulsion (ISP), Inc. with Daniel Meyer to design and manufacture composite propellant rocket motors for aerospace, military and industrial applications. 1985 also marked the year that AeroTech and ISP first moved their facilities to Las Vegas and in 1987 they moved again to an industrial complex at 1955 South Palm St.

By 1988 AeroTech had established itself as the largest supplier of technically advanced rocket motors for the hobby rocket market. In 1989, AeroTech acquired the assets of Enertek, Inc., a Phoenix, AZ-based model rocket company that sought to enter the "E" through "G" power portion of the model rocket market. Also in 1989, AeroTech was acquired by ISP in a transaction that brought Paul Hans, an Enertek co-founder and model rocket pioneer, into the company.

I sold all of these after we won the BATFE lawsuit . . .

since hybrids came up
54mm hybrid I made



and what I hated about it

Does anyone have any pics or remember Energon? Back in the '90s, I knew some of the folks involved in MRED (Microbrick, Rocketflite, Energon, Dangerous Dave). I believe they had an L motor certified at the time, but then MRED imploded.

L1000 I believe. Single use 3".motor. I think Down Right Ignorant had 5 of them.

Thread revival! Hello, old friends.

Anybody know what this is? 29mm, about 11” long with a mega graphite nozzle. Gary R thinks it’s a John Davis motor. Core is likely coated with anthracene. And it could be low pressure long burn motor, despite the giant nozzle.

Wrong thread....

Sweet, keep them coming!

Here is a link to some of the weather rockets called Rocketsondes

https://www.eoas.ubc.ca/courses/atsc201/A201Resources/SoundingUBC/BalloonLaunch.html
A friend of mine use to own and run the Radiosonde Museum Of North America and had one of the Rocketsondes in
his collection it was called a PWN-7A Rocketsonde

Also I remember when we use to launch at Fort AP Hill VA I was told the Vulcan Smokey Sam Motors were used in a rocket made of foam
and were used to simulate a surface launched missile at low flying aircraft

About three hundred posts ago I posted up a picture of a 30 plus year old AeroTech J285. Last summer I flew it in my trusty (crusty?) Magnum. It worked perfectly...

I'll be flying a LOC Magnum next weekend at XPRS on two old motors. A Ron Urinsco L500 spitfire and then a Vulcan J340 smoky sam. Will post pics and video.
