Identifiable vibration characteristics of contemporary military helicopters are described. These provide a basis for analyzing and interpreting the literature on vibration research. Emphasis is given to experimental results which relate to frequencies and acceleration amplitudes falling within the helicopter main rotor effects region. The spectrum of military helicopters is tabulated briefly and six representative Navy/Marine Corps helicopters, missions and associated flightcrew tasks are described in more detail. Perceptual-motor behaviors comprising crew tasks in the six missions are identified. These are used to relate vibration analysis results to the helicopter situation. (Author)
