Wake Transition of the Hypersonic Vehicle and Its Influence on RCS

doi:10.3969/j.issn.1000-1093.2019.12.010

Abstract

Abstract: A long plasma wake is formed downstream when a hypersonic vehicle is flying in the atmosphere. It may cause a sudden increase in radar cross section (RCS), which affects the detection, tracking and identification of hypersonic vehicle. The flow field characteristics of hypersonic model in the free flight ballistic range is experimentally studied. The flow field structure and transition position of wake at different Mach numbers and chamber pressures were measured. The possible influence of transition position on the RCS characteristics of hypersonic vehicle is discussed. The results show that the model feature size, flight Mach number and chamber pressure are the main parameters affecting the transition position. The influence of the plasma wake on the hypersonic vehicle RCS is very complicated, which changes RCS and makes the radar imaging blurry, and even produce the fake targets. Key

Key words: radarcrosssection, hypersonicvehicle, ballisticrange, freeflight, waketransition
