1. A propulsion system for an aircraft, 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;
one or more ejectors fluidically coupled to the plenum via one or more valves, the one or more ejectors being integrated respectively with one or more airfoils having trailing edges, the one or more ejectors each comprising first and second sidewalls tapering toward the trailing edges, wherein the ejectors are rotatable through at least a 90° angle with respect to the plenum, wherein the one or more erectors comprise:
a convex surface,
a diffusing structure coupled to the convex surface,
at least one conduit coupled to the convex surface and configured to introduce to the convex surface the compressed ambient air, and
an intake structure coupled to the convex surface and configured to introduce to the diffusing structure a secondary fluid accessible to the vehicle, wherein the diffusing structure comprises a terminal end configured to provide egress from the system for the introduced compressed air and secondary fluid; 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 one or more valves into the one or more ejectors, and
the system operates in a second configuration in which the one or more valves are closed, the nozzle vanes are open and, the compressed ambient air exits the plenum only through the output port.
