ABSTRACT

The experimental data of the investigation of stability of a 3D supersonic boundary layer on a swept wing are presented. The experiments are performed on a swept-wing model with a lenticular airfoil, with a swept angle of the leading edge of 45 deg, and at Mach number M = 2. Development of natural disturbances on the model of a thin swept wing is studied in detail on the basis of measurements. The characteristic regions of disturbance development are obtained. The Reynolds number of the region of instability of secondary flow disturbances is experimentally determined. It is shown that the secondary instability of a cross flow plays the main role in a laminar flow transition in the supersonic boundary layer on the swept-wing model.
