TURBULENCE SCALE PARAMETER AND SPECTRUM IDENTIFICATION

Abstract

Four sets of atmospheric turbulence flight records have been analyzed using NAPAM natural parameter based assessment and analysis methods. Pre-processing operations included calculation of a suitable runnung mean function. Values of the standard deviation, of the integral scale L and of Taylor's scale were calculated from the definition formulae and checked by the spectral density functions. Shape parameters for the generalized Karman spectrum, too, were calculated and checked. Experimental calculations indicate the existence of a discrete frequency amplitude spectrum function and research is proceeding to verify (or to disprove) this assumption.
