Pi. Kovalev et al., Investigation of the aerodynamic properties and flow field around hypervelocity objects in a ballistic test range, TECH PHYS, 44(12), 1999, pp. 1402-1406
The equipment of a ballistic test range for research on hypersonic motion a
nd flow around typical models of explosion-propelled projectiles. A method
for obtaining instantaneous interferograms of the flow around an object and
a procedure for calculating the radial density distributions from measurem
ents made on them are briefly set forth. The values of the aerodynamic drag
at zero angle of attack are obtained for three models in trajectory experi
ments, and a comparative assessment of their stability is made. The princip
les for performing numerical aerodynamic calculations of hypervelocity flow
around objects typically having a compound shape are formulated. (C) 1999
