Cockpit vibratory level indication device for helicopter, has analyzing unit decomposing acceleration signal into axial analyzing signals, and control circuit effectuating sum of powers of weighed analyzing signals to determine level

摘要

The device has an analyzing unit (FT1) for decomposing an acceleration signal (gamma ) into several axial analyzing signals having respective predefined frequency bands. A memory (RM1) stores axial weighing coefficients, where each of which corresponds to the predefined frequency band. A control circuit (CC) effectuates the sum of powers of the axial analyzing signals weighed by the axial weighing coefficients to determine a vibratory level (VIB1).
