    Abstract

    On-orbit Vibro-acoustics has found exciting applications in modern manned space systems because of audible noise/human vibration requirements.

    In the frame of this paper, the results of ATV Design & Verification approach vs the NC50 and the ISS Micro-g requirement are presented.

    The aim of this paper is to highlight:

    • the integrated Test/Analysis approach selected for the Design & Verification of the Pressurized modules
    • the specific developed methods on how to characterize the disturbers I/F forcing function and their emitted acoustics for the full control of the budget contributions to the System induced Vibro-acoustic environment
    • the recovery actions selection methodology and their design for compliance achievement and pleasant acoustic environment performance
    • On-field diagnostic test method to find out unexpected disturbers impact for their further recovery means implementation as per ATV project.
    • Diagnostic post-processing approach on measured data for the selection, Design and implementation of technical solution involving crew activities in the frame of the on orbit tasks of the passive recovery means
    • Validation testing to see the effect of the implemented acoustic means
    • Standardization of “Industrial procedure” for the next manned Spacecraft project generation derived from the AAS-I acquired experience for the On-orbit Vibroacoustics control in the selected Design & Verification approaches
    • the sharing of the verification approach at Unit, S/S and System level to optimize test philosophy and to save cost.
