Aircraft with an unducted fan propulsor

Abstract

The present disclosure is generally related to aircraft having one or more unducted fan propulsors at locations within specific regions relative to an airfoil, such as a wing or horizontal stabilizer. More specifically, the specific regions are located where there is a relatively higher pressure air flow beneath the wings or above a horizontal stabilizer. That higher pressure air flow can be utilized to provide increased thrust from the unducted fan propulsor. An unducted fan propulsor may further include an outlet nozzle that expels an exhaust stream at a non-zero angle with the centerline of the unducted fan propulsor such that the centerline is oriented downwardly relative to the exhaust stream. The outlet nozzle may further include a core cowl shaped to cause a bypass or third stream flow to entrain a core exhaust stream.
