An aircraft designed with three wings located on either side of the fuselage. The forward wing has a downward angle with a curved top and bottom surface. The upper wing is located towards the rear of the aircraft and above the forward wing. The lower wing is located below the upper wing and slightly forward. It is also located to the rear and below of the forward wing. The outer ends of all three wings come into contact at one point. The forward wing uses the Coanda effect to increase the airflow across the top surface of the bottom wing. The aircraft can be designed so that it is large enough to carry people and/or cargo, or to be small enough to be flown as a toy aircraft. The like design can use any type of aircraft engine commonly used today. One embodiment of the aircraft has two turbines, shaft-coupled to a power source, located on either side of the forward end of the fuselage. Each engine has part of its thrust diverted through and directed by a plenum disposed internal of the coanda toward both sides of the fuselage so that an equal amount of thrust flows through the duct and over the wings on either side of the fuselage. This ensures equal lift on the coanda and both wings on either side of the fuselage in the event that one engine malfunctions.

What is claimed is: 1. An aircraft comprising: a fuselage with a forward end, an aft end and two lateral sides; a pair of coanda each with an inner and outer end; a pair of upper wings each with a leading edge, a top surface, a bottom surface, a Kruger flap, an inner end and an outer end, wherein the Kruger flap is located on the bottom surface aft of the leading edge; and a pair of lower wings each with an inner and outer end; one of the coanda is disposed on either side of the fuselage with the inner ends attached to the lateral sides of the fuselage; one of the upper wings is disposed on either side of the fuselage with the inner ends attached to the lateral sides of the fuselage, located aft and above in relation to the coanda; one of the lower wings is disposed on either side of the fuselage with the inner ends attached to the lateral sides of the fuselage, located aft and below in relation to the coanda, and below and forward in relationship to the upper wings; the outer ends of the coanda, upper wing and lower wing located on each lateral side meet and directly contact each other. 2. The aircraft as claimed in claim 1, wherein the coandas have a curved top surface and a curved bottom surface and a generally downward angle with relation from forward to aft of the fuselage. 3. The aircraft as claimed in claim 1, wherein the upper wings have a curved upper surface and a flat bottom surface. 4. The aircraft as claimed in claim 1, wherein the lower wings have a curved upper surface and a flat bottom surface. 5. The aircraft as claimed in claim 1, further comprising a propeller driven by an engine mounted on the forward end of the fuselage. 6. The aircraft as claimed in claim 1, further comprising a propeller driven by an engine mounted on the aft end of the fuselage. 7.
