“…While most of the attention has gone to minimizing community noise, the choice of an aft-mounted propulsor eliminates the top two sources of cabin noise, namely the interaction between the turbulent vortex being shed from the tractor propeller and the windscreen and side windows [22]. Given the much higher speed, and therefore power setting, of the PAV, it is unlikely that automobile levels of noise can be attained because of wind noise and engine noise.…”

Not only is the common dream of frequent personal flight travel going unfulfilled, the current generation of General Aviation (GA) is facing tremendous challenges that threaten to relegate the Single Engine Piston (SEP) aircraft market to a footnote in the history of U.S. aviation. A case is made that this crisis stems from a generally low utility coupled to a high cost that makes the SEP aircraft of relatively low transportation value and beyond the means of many. The roots of this low value are examined in a broad sense, and a Next Generation NASA Advanced GA Concept is presented that attacks those elements addressable by synergistic aircraft design.
