Correction to: Ferric Oxide Colloid: A Novel Nano‑catalyst for Solid Propellants

90Y ferric hydroxide colloid.

At the Radiochemical Centre we have recently developed a new 90Y colloid which has greater stability than the currently available 90Y silicate colloid and appears from the results of animal tests to be suitable for the treatment of rheumatoid knee joint effusions. In this report the need for a new 90Y colloid is assessed and the preparation and properties of the new colloid are described. Curre...

Constitutive Equations for Solid Propellants

Mechanical behavior of the Space Shuttle redesigned solid rocket motor (RSRM) propellant is studied from a phenomenological point of view. Motivated by the study of the experimental data three initially isotropic constitutive models have been developed. All models represent the e ect of strain rate, superimposed hydrostatic pressure, and cyclic loading on the stress and dilatation response of t...

Combustion Mechanisms of Solid Propellants

Low Acid Producing Solid Propellants

The potential environmental effects of the exhaust products of conventional rocket propellants have been assessed by various groups. Areas of concern have included stratospheric ozone, acid rain, toxicity, air quality and global warming. Some of the studies which have been performed on this subject have concluded that while the impacts of rocket use are extremely small, there are propellant dev...

Constitutive Modelling of High - Elongation Solid Propellants

A phenomenological approach is used to represent the nonlinear viscoelastic behavior of solid propellants. A three dimensional nite strain viscoelastic model, modi ed by a strain softening function that accounts for damage e ects, is considered in the research. Some of the signi cant aspects of high-elongation propellants are incorporated into the constitutive model. The resulting stress-strain...
