Abstract
A computer program for tbe analysis of correlated multiple-input/single-output systems bas been developed using the techniques of Bendat. This iterative procedure allows spectral separation to enable sequential as well as13; combined inspection of input/output relationships. The analogy of conditioning of spectral density functions to13; that of Gaussian elimination bas been used for efficient realization of the algorithm. Described are the method13; and its applications to flight test data of two research vehicles, a helicopter and a new in-flight simulator. The examples show the detection of extraneous noise at the output caused by a fewer number of inputs together with13; the investigation of the control buildup in the helicopter case, and in the other case the influence of the autotrim13; system of the in-flight simulator on its direct lift control flaps. The results and conclusions are drawn based on the investigation of spectra and coherence functions.
