Solid Rocket Motor Internal Insulation
by Hercules Incorporated, Aerojet, Jet Propulsion Laboratory, and NASA Lewis Research Center
Most solid rocket motors use a layer of heat-barrier material between the internal surface of the case and the propellant. This internal insulation prevents the case from reaching temperatures that endanger its structural integrity. In addition, the insulation performs important secondary functions:
- Inhibits burning on certain propellant grain surfaces
- Buffers the transmission of case strain into the propellant
- Prevents impingement of combustion products on the case
- Seals the case, joints, and fittings to prevent loss of pressure and damage from hot combustion products
- Guides combustion products into the nozzle in laminar flow to the greatest extent possible
Almost all of this data and information was classified as secret until the time of this report. This fine handbook will provide solid information for everyone who designs, builds, tests, or uses serious solid propellant rocket motors. It's an official NASA design guide, full of scientific data, rocketry information, and military missile lore. And it's the ideal text for "amateur" experimental rocket scientists. Heads up, all you serious "amateur" rocket scientists and engineers!
Prepared at the NASA Lewis Research Center by scientists and engineers from Aerojet-General Corporation, Hercules, JPL, and NASA, this valuable book gives the practical information you need. It's a book by the experts, for the experts! The contents are the result of more than 40 years of investigations by the world's largest propulsion contractors. Literally millions of dollars were spent obtaining this critical yet hard-to-find data.

Perhaps most complete and comprehensive book ever written about the theoretical and practical engineering design of solid rocket motor insulation and insulators. Based upon the extensive design experience accumulated in the development of internal insulation for many kinds of rocket motors. Flow charts show schematics of interrelated procedures in design of an insulator. Discusses many kinds of binders and fillers, for use with dozens of propellant types. Shows the design of test motors for screening and evaluating candidate insulation materials. Includes all the mathematics, formulae, and equations necessary for the design process.
Includes detailed data and information about the insulation used in these rockets and missiles:
- Athena X-259
- Redhead, Roadrunner, Redeye
- Nike Zeus 1S
- Saturn ullage motors
- And many others
