Abstract
Keywords
We developed a speckle-interferometer plant to investigate
turbo-machinery wheels vibrations. We placed the plant
optical arrangement and the object under investigation on a
massive holographic plate. By using the plant we obtained
frequencies and modes of aircraft engine wheel vibrations.
To investigate the part vibrations, in working area condi-
tions we designed another speckle-interferometer requiring
no interferometer plate (table). With the help of this plant,
we performed investigation of frequencies and modes of fan
blades lot vibrations
