Abstract: The invention provides a fluid propulsion augmentation arrangement and method, capable of also generating control moments (23), providing increased thrust (45) at reduced speed, reduced drag at increased speed, under conditions in which traditional approach cannot provide sufficient performance. It consists of a wing (10) located in a propulsion system (11) fluid intake region (13), having a slanted trailing edge (16) coinciding with a fraction of the propulsion intake (17), pivotally connected (14), allowing position adjustments. At reduced speed, the wing (10) and the propulsion system intake (17) are placed adjacently, the intake low pressure determines wing (10) fluid-dynamic force (44) generation. Increasing speed, wing (10) position varies, following fluid stream (15) convergence change, maintaining an angle of attack for increased L/D, ensuring increased performance, and also varying control moments (23).
