摘要

The dynamic instability of a slender front-fixed-aft-free elastic strip in a uniform airflow is studied analytically. The analysis is performed by using the unsteady slender body aerodynamci theory and the beam oscillation modes as a result of aerodynmaic force when the flow speed overcomes the critical speed. One approximate method is derived, and the flutter speed, mode, and frequency are examined numerically.
