A device to augment air mass flow so an exit airflow will have a higher exit velocity than an inlet airflow has an inner structure having a first open end and a second open end. The inner structure is hollow. The inner structure tapers down from both the first open end and the second open end to a neck area. At least one opening is formed in the neck area. An outer structure has a first open end and a second open end. The outer structure is hollow. A diameter of the first open end of the outer structure and the second open end of the outer structure are approximately equal and allow the inner structure to slide within the outer structure. At least one outer structure opening is formed in a central area of the outer structure.
