The Micrograin Rocket
by William Colburn
"Step-by-step Classic Micrograin Rockets"
Bill Colburn explains the origins of the Micrograin (Zinc and Sulfur) rocket technology, its early uses and the theory of operation. Then the book goes into great detail on how these classic rockets were actually made, how they performed and how altitude measurements were accomplished in the early days along with many recovery techniques for these high acceleration beasts. Many concrete examples and drawings of this historical period are also included. Up to date information is included from extensive testing of the MicroGrain Effect by careful researchers.
