Analysis of the three lowest bending frequencies of a rotating propeller (1936)
NASA Technical Reports Server (NTRS) · leaf 17
Figure 1.- Oscillation frequencies of rotating propeller versus revolutions. Frequency \ and revolution w are referred to static frequency Ag. The scales for #/Ao have been chosen such that each plot approximately covers the normal range of propeller operation. The scale for A/Agis the same… … conformably to I.
