Detecting the infrared characteristics of contrails is a reasonable approach to tracing rocket, and particle properties are basis analysis. The conventional numerical obtaining Euler/Lagrange method or simple Euler/Euler method, difficultly more accurate results because it ignores size distribution in parcels cells. A modified applied simulate contrail formation near field solid rocket motor at...

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...
