On the static stability of forward swept propfansAn hybrid Euler solver coupled with a NASTRAN structural analysis is used to investigate the static stability characteristics of two forward swept propfan blades. The designs, having same geometry but different structural properties - one being statically stable and the other unstable, are analyzed. The stable design takes more iterations to converge than previously designed aft swept blades. The unstable design diverges to an unrealistic shape within five iterations.
