Web1 apr. 1991 · An analytical investigation of the air‐ and ground‐resonance characteristics of simplified hingeless‐rotor helicopter configurations was undertaken. The objectives were to identify and interpret the unique characteristics of coupled rotor‐body modes that determine air‐resonance stability characteristics, as contrasted to ground‐resonance phenomena. Webinto a condition called ground resonance if one landed while moving in a direction other than straight down. It isn’t a condition that one could expect to happen often, but there in …
