Jet AeroacousticsGanesh Raman An up-to-date survey of airplane noise, this single-volume reference thoroughly addresses the key problems facing aeronautical engineers. By tackling the most important aspects of jet aeroacoustics, including theories of jet noise, the design of jet noise facilities, and how jet noise is measured, this thoroughly researched analysis outlines a plan for first limiting the current distress being vocalized in issues of passenger cabin comfort and protests by those living near airports and later for finding an overall solution to jet noise. |
