The dynamic and flutter properties of the new airfoil model NACA0015
Original language description
The new airfoil model NACA0015 (with a chord length of 59mm, thickness 8.85mm and width of 76.6mm) was traditionally proposed as the dynamic system with two near eigenfrequencies 13.3 Hz and 17.1 Hz corresponding rotation and transversal movability. Thisdesign allows the generation of self-excited motion of the airfoil in subsonic air flow with Mach numbers M = 0.2 ? 0.4. Inside of the airfoil are placed angle sensor and four semiconductor pressure sensors. For time registration of the transversal movement of the profile rotation centre, the contactless magnetic linear sensor is used. In the paper, the identified eigenvalues and eigenmodes for zero flow will be compared with flutter properties (frequency, modes, time evolutions) of the airfoil situated in the aerodynamic tunnel of the Institute of Thermomechanics AS. The evaluated sensor data serve for the correction of classical interferometric measurements supposing isentropic flow.
