1. A propulsion system for an aircraft, the propulsion system comprising:
a plenum having an intake port and an output port;
a fan coupled to a motor configured to power the fan, the powered fan configured to compress ambient air entering the intake port;
at least one aerodynamic control surface;
at least two ejectors integrated into the at least one aerodynamic control surface and fluidically coupled to the plenum via at least two valves; and
a nozzle disposed within the output port, the nozzle comprising a set of vanes, wherein:
the system operates in a first configuration in which the nozzle vanes are closed and the compressed ambient air exits the plenum only through the at least two valves into the at least two ejectors, and
the system operates in a second configuration in which the at least two valves are closed, the nozzle vanes are open and, the compressed ambient air exits the plenum only through the output port.
