- Abstract:
- For research of aeroelastic behaviour of bodies at non-linear aerodynamic interaction it is necessary to measure not only the first, but also high harmonics of aerodynamic loading on vibrating bodies. In the presented work, various ways of the non-stationary aerodynamic forces determination are analysed. Substantiation of the mentioned forces measurement through a electrical current in the vibrator mobile coil is handed. That is valid under condition of the proportional - differential feedback utilising in the oscillation control system of the tested bodies.
