Howard Kuhn Scale Data Available
In response to a request on TRF, Dave Fitch sent me the scale data he had from Howard Kuhn on the Nike Tomahawk and I Beam launcher. I've made those files available on my web gallery here, http://www.cv41.org/personal/galler...wk-and-Launcher
Thanks to Dave for sharing

You know the Nike booster has to be pretty dang stout considering it only moves a few inches before it's free and clear of the I Beam launcher. Inertia will keep it pointed the general direction for a second or two, but the booster has to get it up to speed PDQ for the fins to stabilize it. There is no guide rail like there is with most systems.

It's plenty stout.
The U.S. Army built their rocket boosters using the knowledge from the main vehicles they knew....TANKS ! Lots of metal and lots of power.

Buzz, Actually, Howard's data only pertained to the I-Beam Launcher. The Nike-Tomahawk data is from the 1983 Model Rocketeer Super Scale article, based on "edited" Don Larson data, done by the author of the article. In doing so, he introduced an ERROR into the data, by calling the "Cream-colored" stripe on the Nose Cone "Natural Steel". "Natural Steel" is impossible, since the White, upper portion of the nose cone is Ceramic, while the lower Brown section is Phenolic. I believe that the "Cream-colored stripe" in the original 1974 Model Rocketeer data is actually a strip of masking tape, likely used when the two sections of the nose cone were bonded together.

Thanks for the correction Dave. I forgot that was Don's article.

The 1974 article was Don Larson's article. The 1983 one was written by Craig Beyers. In the 1983 article, Beyers claimed to have collaborated with BOTH Don Larson and Howard Kuhn. I can't vouch for whether he talked to Kuhn or not . . . BUT, when I visited Don Larson in September, 2004 to pick up all of his original data on Nike-Tomahawk 18.26 IA, I showed him the 1983 article. He had never spoken with Beyers or collaborated with anyone on 18.26 IA and the article was a complete surprise to him . . . Interpret that as you will ! Don immediately noticed the aforementioned error and he was upset that his participation had been misrepresented by Beyers, along with his drawings & photo's being used, and altered, without his permission.

Jerry, Actually, that is already "in the works" . I'm collaborating with another NAR modeler to do exactly that and more. After several years of research, accurate, verified data has been recovered to finally do 18.26 IA justice, much more detailed than either article ! Dave F. |
