Handbook, Structural Design Nomograph for Thermal Cycling of Tactical Rocket Propellants.

Abstract

The Structural Design Nomograph (SDN) is an analytical device for predicting the conditions for failure of tactical rocket propellant grains. The nomograph discussed in this handbook considers these failures to be the result of repeated thermal cycling (under conditions where stress-ratcheting is prevented). The most practical use of the SDN is as a preliminary design tool that permits rapid and inexpensive calculations by both chemists and engineers from which they can assess the effects of design changes and variations in propellant mechanical properties. These analyses are relatively inexpensive since they can be performed about 20 to 50 times faster than the input time to the computer for the corresponding viscoelastic analyses. Also, no mathematical talents are required to conduct the nomographic analyses. They can be performed by non-engineering, non-mathematical personnel. The nomographic analysis involves approximations to the highly sophisticated, linear, thermo-viscoelastic stress and damage analyses.
