Description

This paper was planned in order to make clear the wake interaction in a tarbomachine. The analysis of the unsteady force on a cambered blade with angle of attack moving through sinusoidal gusts has been extended to a form suitable for arbitrary gust patterns. An attempt has been made to predict the unsteady force on a cascade blade due to an upstream moving cylinder. In this case, the unsteady force can be considered as owing to the wake effect, the cylinder-thickness effect and the neighboring blade effect. The computed results were given graphically for each effect respectively.
