Ejector and airfoil configurations

TLDR
In this paper, a propulsion system coupled to a vehicle is described, which includes an ejector having an outlet structure out of which propulsive fluid flows at a predetermined adjustable velocity.
Abstract
A propulsion system coupled to a vehicle. The system includes an ejector having an outlet structure out of which propulsive fluid flows at a predetermined adjustable velocity. A control surface having a leading edge is located directly downstream of the outlet structure such that propulsive fluid from the ejector flows over the control surface.
