YC-14 Interior Noise Measurements Program

reportActive / Technical Report | Accession Number: ADA098799 | Open PDF

Abstract:

A test and preliminary analysis program was conducted to develop a data base and initial understanding of the interior noise of a Upper Surface Blowing STOL airplane using the YC-14 as a test vehicle. A data base has been secured consisting of concurrent cabin noise exterior fuselage fluctuating pressures fuselage wall vibrations and associated aerodynamic, propulsive, and mechanical performance values covering the normal operating envelope of the airplane. Results from preliminary analysis of data show orderly and intuitively reasonable trends. The resultant data base is judged capable of supporting further detailed analysis.
