description To obtain an augmented lift coefficient for a given airfoil set at a maximum angle of attack (alpha), in a steady state airflow system, a shrouded motorized propeller is installed normal to its upper side, creating additional airflow. An outlet for the additional airflow is provided including a horizontal motorized propeller placed at the trailing edge of the airfoil. The motorized propeller converts the additional air flow into a down-wash generating additional lift. Neither the first nor the second installation alone will produce the augmented lift efficiently. Therefore, the combination of the first and the second installation is needed. The propeller-wing arrangement is implement in the airfoils.
