T1 - Instability and bifurcation of transonic flow overairfoils

AU - Kuz'min, Alexander G.

N2 - An investigation of inviscid transonic flow over a flattened airfoil whose curvature is small in the midchord region is performed. Numerical simulation reveals a bifurcation of steady solutions to the Euler equations in a range of freestream Mach numbers M∞ and angles of attack α. The dependence of the lift coefficient CL on M∞ and α is studied in the intervals -1.2 < α, deg < 1.2, 0.79 < M∞ < 0.85. A theoretical interpretation of the bifurcation and instability phenomena is presented.
