Estes Teros kit's inspiration?
 
Hello All,

As the Centuri Nomad was inspired by the Terrier (or was it the Tartar?) U.S. Navy SAM, was the Estes Teros kit (see: http://www.spacemodeling.org/jimz/est1285.htm ) inspired by a full-scale ramjet test vehicle or prototype missile?

In the past I have seen photographs of NACA and contractor (Boeing, I think) ramjet test vehicles that resembled the Teros. Some of the NACA ones launched at Wallops Island used solid-fuel ramjet engines, and the Boeing one (I believe it was called "GAP," but I don't know what the letters stood for) had a paint scheme reminiscent of the one on the Teros.

I think more like the old Navy TALOS missile

I built a prototype a long time ago but it needed so much nose weight to make it stable I never did fly it.

No, I'm referring to wingless ramjet test vehicles that looked like ordinary rockets, with fins at the rear but with no wings like the Talos & Vandal had, but with an axisymmetrical (Talos-like) ramjet air intake at the nose. These ramjet test vehicles looked somewhat like the Estes Teros.

Ah, now we're "getting warmer"--thank you for posting this photo, Chris! That NACA one looks similar to (and may have been an early version of) a similar 4-finned, wingless NACA ramjet test vehicle that was carried aloft by an F-82 Twin Mustang and air-launched over the Wallops Island test range (the one I remember lacked a tapered boat-tail at the rear).

The NACA solid-fuel ramjet test vehicle I saw photos of (which looked more like the Teros) had three delta fins and was launched at Wallops Island atop a surplus rocket motor (a Recruit, I believe). The photos and descriptive text on these and many other ramjet (and rocket) vehicles are in James Shortal's book "A New Dimension" (it has a sub-title that has "Wallops Island" in it, but I can't remember how it goes). Mark Bundick would know, as he has a copy of the book.

I have that book.
There is a pic on page 263 which appears to match your search.
May 22, 1952.
Also another pic on page 264 which look like a similar vehicle.
Mar 23, 1955.
Both were Deacon-boosted.

Those look even more like the Teros kit--just whack off the fin corners at an inward-slanting angle! There is a picture of a three-finned version (it might be a variant of the same ramjet vehicle) on a booster rocket elsewhere in the book, but I like the 4-finned ones better. Yep, the Deacon was Wallops' favorite motor for these test vehicles because they were plentiful and cheap (and they could--and did--cluster them when more thrust was needed).
