Patent ID: 7147183

Claim:
A propulsion system comprising: an airflow inducement mechanism; a coanda comprising a leading edge and a trailing edge; a wing comprising a leading edge and a trailing edge; and a base having a curved surface; the coanda is located adjacent the airflow inducement mechanism; the wing is located adjacent the coanda such that there is a gap between the coanda and the wing; wherein the coanda and wing are mounted above the curved surface so that it defines a passageway between the curved surface and the wing and the coanda such that a first airflow generated by the airflow inducement mechanism flows through the passageway and induces a second airflow through the gap between the coanda and the wing, the second airflow creates a venturi in the passageway causing the velocity and density of the first airflow to increase, the second airflow creates a lift, the lift comprising lift generated by a Bernoulli principle acting on the curved surface and exits radially outward from the passageway.
