Аннотация:Results obtained for experimental studies on a supersonic flow over an axisymmetric cylindroconicalbody with an annular cavity of a rectangular axial cross section at an angle of attack andat Mach number M = 2.5 are presented. Data visualization of the flow structure, pressure measurements,and weight testing have been obtained for relative cavity lengths ranging from 6 to 18. The structureevolution and parameters of the flow over a cavity has been studied under a continuous changein the angle of attack in the range from ‒ 4 to 16 degrees. Different flow modes corresponding toclosed, open, and combined patterns of flow over a cavity have been identified. The existence rangesof aerodynamic hysteresis in the transition between flow modes from one pattern of flow over a cavityto another have been estimated in the space of dimensionless problem-determining parameters.\\________Supersonic Flow over Annular Cavities at an Angle of AttackJanuary 2023Fluid Dynamics 57(S1):S65-S74DOI: 10.1134/S0015462822601292 \\____________ Received \\14 March 2018Revised \\14 March 2018Accepted\\14 March 2018Published\\09 January 2023Issue Date \\December 2022
