Flutter transonic operation line
Web• ZTRAN can capture transonic shock effects and transonic flutter dip, whereas DLM/ZONA51 cannot because of the linear potential flow theory. • Without capturing the flutter transonic dip, the optimized structure is prone to having flutter problems. 100.0 150.0 200.0 250.0 300.0 350.0 400.0 450.0 500.0 550.0 Web2.4. Transonic flutter analysis in the frequency domain. Traditional flutter methods in the frequency domain, such as the p-k method, v-g method and g method, are the methods most commonly used by engineers. However, a significant amount of work is required to convert the equations from the time domain to the frequency domain in the fluid ...
