Flow discouraging systems and gas turbine engines

[0017]The following detailed description is merely exemplary in nature and is not intended to limit the inventive subject matter or the application and uses of the inventive subject matter. In particular, although the inventive subject matter is described in the context of turbofan gas turbine engines, the inventive subject matter may be implemented in turbojet, turboprop, turboshaft, auxiliary power generation and pneumatic pressure generation gas turbine engines or any other engine in which a flow discouraging system may be useful. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

[0018]FIG. 1 is a simplified schematic of a gas turbine engine 100, according to an embodiment. In accordance with an embodiment, the gas turbine engine 100 may include a system that maintains a flow of hot combusted air along a designated flowpath by reducing or preventing the leakage of the hot combusted air into spaces
