COMPLEX NOTATION IN FLUTTER ANALYSIS. DISCUSSION AND CLOSURE

A discussion of a technical note with the aforementioned title by U. Starossek, published in this journal (Volume 124, Number 8, August 1998), is presented. In the discussers' opinion, when comparing real-number and complex-number expressions of aerodynamic forces for flutter analysis, the choice of using a real or complex number format should depend on whether the flutter derivatives or complex coefficients are more conveniently measured or predicted, since the discussers see no significant differences between them in terms of compactness and computation efficiency. Discussion is followed by closure from the author.
