PLOT-cryoadsorption concentrates headspace vapors by sweeping them through porous layer open tubular (PLOT) capillaries chilled to 0 °C promote adsorption onto an alumina layer. Compared passive concentration employing activated charcoal strips (ACSs) as adsorbents, has several potential advantages for extracting ignitable liquid (IL) residue from fire debris evidence. Capillary vapor traps can...

To improve the performance of a solid rocket motor (SRM), multiobjective optimal design method that can consider structural integrity, internal ballistic performance, and loading SRM was proposed based on parametric modeling surrogate technology. Firstly, technology introduced into field integrity analysis for high-loading SRM, which influences load geometric parameters maximum von Mises strain...
