Default Gauchito scale data (link)

Hello All,

I just tried the website URL for Pablo de Leon & Associates that's included in the Estes Gauchito kit instructions, and it's up (see: http://www.pablodeleon.com/ )! It's in Spanish, but there is a "Click here [an American flag] for English" version of the site. A couple of the pages are available only in Spanish, but that's easily remedied by copying-and-pasting their text into FreeTranslation.com www.freetranslation.com , which can translate just about any language into any other language. The Gauchito site contains technical data, illustrations, and photographs of a large-scale (it looks like half-scale or so) Gauchito mockup. Also:

The Gauchito project may even be continuing, because its listed uses include suborbital experiments (using it as a manned or unmanned sounding rocket with recoverable payloads) as well as space tourism, and the website is copyrighted up to 2012. Also, the firm isn't a "one-project one," because Pablo de Leon & Associates have designed small satellites and Shuttle payloads that have flown, and they maintain an office at Cape Canaveral.

I hope this information will be helpful.

Or for users of Google Chrome, it'll offer to translate the pages for you.

Unfortunately the page's text (English version) appears to be unchanged from December 2005:

http://wayback.archive.org/web/2005...m/index_en.html

so I doubt the 2012 date on the web site is very meaningful as far as currency of its information.

Interesting stuff, thanks!

That's good to know--Thank You. (I'm still using an old Windows XP machine; when I get my new Acer computer hooked up and running, I'll be able to use Google Chrome.) Pablo de Leon is still active, so it's possible that Gauchito--or a newer development of it--may fly in the future. Argentina is developing a liquid propellant satellite launch vehicle called Tronador II ("Thunderer II"), so their rocket technology is advancing, if rather slowly (they've built and flown a few indigenously-designed solid propellant sounding rockets with good success). Gauchito's LOX/polymer hybrid rocket propulsion system and rocket/capsule (rather than winged) vehicle configuration would likely be the safest.

Interesting to hear that it may still be an applicable design. I have an old Estes X-Prize kit of the rocket that I was going to kit bash into a Congreve (I mean, just look at that nosecone!), but maybe I'll hold off on that idea for a little while longer.

The Congreve rockets I've seen have either a much longer nose cone than the Gauchito's (looks like about 2.3:1), or a flat or bulb shaped nose:
(large version)
If I were going to build a conical-nose Congreve I'd probably roll my own nose cone out of cardstock and stiffen with CA, or maybe a BNC60C (e.g. from Balsa Machining) would be close enough.

Hey, I never knew Congreve invented parachute recovery. Cool.

Added: Found a 1:1 papercraft Congreve model .

In my book "All About Rockets and Jets" (a Random House book written by Fletcher Pratt--Willy Ley completed it after Mr. Pratt died in 1956--I think my edition [I'll have to dig it out] was published in 1957), drawings of Congreve rockets show them with blunt, conical noses similar to the Gauchito's. But since the drawings were made by the illustrator of the "All About..." series of books, s/he may have taken some artistic license in creating them. The drawings of the spin-stabilized Hale rocket in the book also differ somewhat from contemporary drawings of it.
