Reviving a two year old thread here, but I *think* I have identified the top stage of the two-stage model in the foreground (standing vertical) of this Enerjet pamplet photo (see attached).

This photo was used in several Enerjet product flyers, this one in particular scanned off the 2650 Sound Rocket flyer. Earlier in this thread, the question is raised about the identity of (what appears to be) the two stage vehicle in the foreground on the tabel top. In particular, the TOP stage.

After looking at this in some detail, I believe that top vehicle is a 'clipped' fin Screaming Eagle! That was my first model rocket, so I'm familiar with it (still have it), and I noticed that the decals (from what we can see) match with the narrow band just above the fin unit and the lower part of the upper roll pattern of the Screaming Eagle (can just see the lower part of the upper roll patter in this photo). White body tube is as the standard, unpainted Screaming Eagle bodytube. It appears that, for this two stage model, they have 'clipped' the lower portion of each plastic fin on the Screaming Eagle fin unit, which makes for a very different looking fin (at first glance anyway), but I've taken my original Screaming Eagle 'in hand' and with a scrap piece of paper or such 'masked out' and 'eyeballed' a clip like that and it does seem to match up.

As I understand it, the Screaming Eagle was apparently developed sometime in or around early to mid 1972, because it is 'introduced' in a dealer news newsletter (earliest I've seen anyway) dated around September of 1972. So, the date of this photo ('around' 1972) could match up with the introductory time period of the Screaming Eagle kit, as we came to know it. It was first showed up in the 1973 Centuri catalog, which would have been issued in latter 1972. Obviously, to make the catalog (or the dealer news in September of 1972), it would probably have been in developement for some months at that point, maybe even back to late '71 or very early '72.

Now, I don't know if that upper stage was a 'powered' stage or not (may have been a boosted dart type setup), but that Screaming Eagle was a pretty sturdy design, and that plastic fin unit would have held up pretty well at high speeds. It also would have been 'in keeping' with the plastic fin unit used on the Enerjet 1340 vehicle.

The transition between the booster and the upper stage appears to be a custom machined item, best I can tell.

Anyway, that's my thoughts as to the identity of this upper stage. Any other additional thoughts or guesses out there?

Earl,

Amazing what you turn up when you search EnerJet on YORF

You are correct, it is a Centuri Screaming Eagle with the fins clipped. I was able to obtain first hand information from Jerry Irvine concerning this rocket. I posted some of the information in this single post here when I was build/flight testing ARG prototype rockets for Taras:

http://forums.rocketshoppe.com/show...900&postcount=7

The thread starts here:

http://forums.rocketshoppe.com/show...ight=prototypes

The two black and white photos in that single post were taken from the 1982 issue of California Rocketry Magazine and featured a scale drawing with a parts list drawn by Jerry Irvine. I don't have permission from Jerry to post the article here so I only cut those two images from the article for comparison to the prototype rocket I was building for Taras.

The transition you mentioned is a Centuri PNC-231 used as a reducer. That model was designed by Larry Brown.

I'd be more than happy to email you the information I now have on this model but I'm reluctant to post the article online without permission. Jerry and I discussed this model during the short lived TIRF forum and that's how I obtained the article.

Steve,

I'm curious. Did you ask Jerry for permission and he denied you permission to post it? If so, let me ask him.

I've never asked his permission. Jerry may not mind I just wasn't sure since it was his publication and he sold that publication at one time through his USR site. It was his drawing.

I don't mind sending him an email asking him if anyone is interested.

Would you please? That would be great. I never entered into all the JI bashing that went on rmr for so long. I've conversed with JI via email in the past and never had a problem with him.

Steve-

Oh, wow!! Geez, I didn't dream ANYone would have such detailed info about a rocket in a 35+ year old publication!! That's fantastic! Kinda neat to have verification of the photo 'analysis', too (seat-of-the-pants as it was...).

Certainly, I'd love to see the additional Jerry Irvine info on this vehicle! Feel free to shoot it to me at your convenience (or post for all if you get permission from Jerry). Yes, I never had any problems with Jerry myself, but I remember at LDRS-10 (Black Rock in '91), he seemed 'public enemy #1' by a great many people for allegedly 'accepting' orders but not shipping anything (his US Rockets days). I never ordered anything from him back then, but apparently, from the sentiment at LDRS-10, a number of folks had those kind of issues. But, that's been a loooong time ago now, and interpersonally, he was always a sweet, sweet guy.

I emailed Jerry and he already responded with a quick reply and had no problem with me posting that image here!

I understand I have been summoned to an Enerjet thread.

If I do not reply timely, please email me, or do so anyway to assure I hear you. I probably have a lot to say on this topic.

I may have to refer to data and physical archives for some answers.

Who else do you know who has dozens of Enerjet G76 casings, an original 2250 an original 2650 and pieces of original 1340's?

Jerry

Jerry,

We welcome your HPR knowledge here. Since we're kind of a repository for keeping the history of model rocketry alive, anything you can post about the "old days" of rocketry when you started out would be greatly appreciated.
