METHOD OF ESTIMATION OF ADEQUACY OF SPECTRAL CHARACTERISTICS OF ACOUSTIC NOISE IN AIRCRAFT SIMULATOR TO FLYING VEHICLE CHARACTERISTICS

摘要

FIELD: manufacture of aircraft simulators at simulation of acoustic loads by noise simulation system at quantitative estimate of adequacy by probability of quality of convergence of acoustic actions to similar characteristics of flying vehicle. SUBSTANCE: method includes estimate of probable compliance of measurement of spectral characteristics of acoustic noise simulated in aircraft simulator at several starts performed in frequency bands of preset range. Statics file is formed for each set, averaged parameters are revealed in frequency band and then magnitudes of mismatch and convergence in probability of spectral characteristics of aircraft simulator are set by adequacy index on basis of results of measurements performed preliminarily on flying vehicle. EFFECT: enhanced reliability. 1 dwg
