A portable normal incidence interferometer is developed, which allows determining the acoustic characteristics of the full-scale liners of an aircraft engine. Studies of large sound-absorbing panels used for lining the aircraft engine ducts are carried out. It is demonstrated that the panels have uniform acoustic characteristics in azimuthal direction.
