Book is FOR AMUSEMENT ONLY! (Post is also for amusement, I hope.)
Price represents my opinion of actual practical value...
When I was learning about APCP in the late 80s and 90s the internet wasn't too well-developed so I bought every practical-info book I could find on the subject. After a time it was clear that the amount of information available greatly exceeded the amount of knowledge. Much like today's internet...
That being said I present to you "Composite Addendum", 52 pages, copyright 1996, apparently a supplement to "Rocket Recipes Book 1", whatever that might have been.
It's clear from professional publications and manufacturer's descriptions that one of the three propellant procedures simply cannot work. I tried it anyway but I was rather younger, quite inexperienced, and prone to wishful thinking. Good thing that the actual hazard was quite low.
The book has hundreds of "recipes" for motors; one page is shown below. Note the dimensions for one of the more sketchy/dodgy recipes, N1342. Don't worry mods, it's just dimensions, though they might just be random numbers. Propellant 39.2" long, 3.3" diameter. "Segments" (grains) 0.82" long, 0.33" core (so a 48-grain motor). Nozzle throat 0.53". Per my former occupation I shall leave evaluation of this and the other recipes as an exercise for the student.
My semi-professional evaluation, now that I'm about 30 years older and perhaps a little wiser:
Hope you enjoyed this!
