Effect of an Isolated Shell on Interior Noise levels in a Turboprop Aircraft 891083
A noise control strategy for a small twin engine turboprop aircraft is evaluated. The noise control strategy consisted of a composite shell suspended inside the aircraft on isolation mounts. The evaluation consisted of a ground test program on component panels to select the shell material and a flight test program on the aircraft with and without the interior shell installed. Results from both phases are presented.
