FAN COWL WITH SERRATED TRAILING EDGE PROVIDING ATTACHED FLOW IN REVERSE THRUST MODE

摘要

To provide a fan cowl with a serrated trailing edge providing an attached flow in a reverse thrust mode.SOLUTION: An ultrashort nacelle configuration employs a fan cowl having an exit plane and a serrated trailing edge. A variable pitch fan is housed within the fan cowl. The variable pitch fan has a reverse thrust position inducing a reverse flow through the exit plane into the fan cowl. The serrated trailing edge forms a plurality of vortex generators configured to induce vortices in the reverse flow.SELECTED DRAWING: Figure 2A
