TL;DR: In this paper, the effect of flow states on the scattering characteristic of plasmas and the interaction of electromagnetic waves with plamas have been analyzed. But the results are significant to the identification, the plasma stealth and the communication of reentry targets.
Abstract: Numerical simulations of chemical reaction flow passing around the reentry target have been carried out with the eleven-element model.The distribution of flow parameters has been obtained for different reentry altitudes and Mach numbers.Based on the results of chemical reaction flow field,with the application of the input impedance method and multilayered medium model,the RCS of the reentry target has been computed using the physical optics method.The effect of flow states on the scattering characteristic has been analyzed.The propagation characteristic of electromagnetic waves in plasmas and the interaction of electromagnetic waves with plasmas have been studied.The results are significant to the identification,the plasmas stealth and the communication of reentry targets.

TL;DR: Algorithms to construct and access terrain oct-trees are presented which form a set of access primitives for tree operations required in TRN applications which provide a basis for a significant reduction in the on-line storage requirement for DT-EDs.
Abstract: This paper describes the use of oct-trees to represent digitised terrain elevation data (DTED) in terrain reference navigation (TRN) systems. Oct-trees provide a regular method to represent digitised terrain data where the level of detail of the terrain is encoded in the tree structure. The use of oct-trees also provides a basis for a significant reduction in the on-line storage requirement for DT-EDs. A method of encoding using Morton ordering is introduced which allows DTEDs to be accessed as oct-trees and quad-trees where the tree structures are represented as pointerless structures. Algorithms to construct and access terrain oct-trees are presented which form a set of access primitives for tree operations required in TRN applications. The paper concludes with examples to illustrate the efficiency of the methods described in the paper for two DTEDs, in terms of performance of the tree access operations and reductions in storage.

TL;DR: In this article, the authors investigated the relationship between flow loss and vortex structures in a high-speed compressor cascade passage and found that the main vortex structures, topological patterns and vortex models in the cascade passage are investigated in detail.
Abstract: In order to find out the internal flow characteristics of compressor cascade in high subsonic flow,research on the occurrence and development of high-speed compressor cascade vortex structures and flow loss are established.Firstly,the simulation model is erected and verified with experimental results;secondly,the main vortex structures,topological patterns and vortex models in the cascade passage are researched in detail;in the end,the relationship between flow loss and vortex structures is analyzed.Seven main vortex structures including horseshoe vortex,endwall span vortex,passage vortex,corner vortex,wall vortex,concentrated shedding vortex and trailing edge shedding vortex are observed in high-speed compressor cascade passage,and passage vortex which originates from the inlet endwall boundary layer is the main reason for the complicated vortex structures.As the angle of attack increases from 0°to 4°,although passage vortex vortex core separates earlier from the corner boundary layer,influences of passage vortex on the passage flow are weakened and concentrated shedding vortex at the trailing edge disappears.According to the cascade topological structure,with the disappearance of concentrated shedding vortex,spiral point corresponding to concentrated shedding vortex on suction surface disappears and the attachment line and separation line at trailing edge corresponding to midspan trailing edge shedding vortex are vanished,indicating that trailing edge shedding vortex only exists near endwall.According to the variance law of totalpressure loss coefficient in streamwise and spanwise direction,cascade passage flow loss is mainly attributed to strong sheering action caused by the complicated corner vortex structures,and the totalpressure loss near endwall is closely related to the occurrence and development of the main corner vortex structures;with the increase of angle of attack from 0°to 4°,however,influences of corner vortex structures are weakened,and the gap between totalpressure loss near endwall and midspan are narrowed as a result of the decrease of flow loss near endwall.
