Abstract

The amphibious aircraft has two top mounted wings and an engine having a rear mounted propeller. The aircraft also has a tail having two wings mounted in a V-shaped fashion. Each of the wings has a pivotal tip mounted thereon. The aircraft also has a sponson on each side of the fuselage by way of horizontally mounted struts. The struts and thereby the sponsons are mounted to the aircraft in such a manner so that they are adjustable in their horizontal attitude. The pivotal wing tips at the top mounted wings control the yaw of the aircraft while the adjustable wing tips in the V section of the aircraft can control both the horizontal direction of the aircraft as well as the right or left direction. It all depends if both the wing tips are pivoted in the same direction or opposite to each other, respectively

Claims

1. An amphibious aircraft having an engine and top wings and a V-tail section, said V-tail consisting of two wings placed in a V configuration, each of the two top wings and the wings in the V-tail section having pivotal wing tips, said airplane further having sponsons having means thereon for adjusting said sponsons in their horizontal attitude.

2. The amphibious aircraft of claim 1, wherein said engine has a rear mounted propeller.

3. The amphibious aircraft of claim 1 including a ventral fence mounted to each end of said wings on which the operating elements of said pivotal wing tips are mounted.

4. The amphibious aircraft of claim 3, wherein said pivotal wing tips are pivoted by a torque tube fastened to the wing tips and running along the length of each of said wings.

5. The amphibious aircraft of claim 3, wherein said torque tube is supported by way of a bearing located in each of said ventral fences.

6. The amphibious aircraft of claim 3 including a multiple of bearings located on each of said ventral fences to reduce any friction between the ventral fences and a wall of said pivotal wing tips.

7. The amphibious aircraft of claim 5 including at least two circular slots located equidistant around said torque tube of said ventral fence, said at least two circular slots receive brackets there through, said brackets are mounted on an inside wall of each of said pivotal wing tips, each of said brackets forming a trunnion on the other side of said ventral fence to support two rollers thereon to guide each of said wing tips relative to their respective ends of said wings.

8. The amphibious aircraft of claim 1, wherein said sponsons each are connected to said aircraft by struts having two ends, one of said ends is mounted to said aircraft and another end is mounted to a sponson, each of said ends having threaded screws thereon.

9. The amphibious aircraft of claim 8, wherein a wall of each of said sponsons and a wall of said aircraft have circular openings therein, said circular openings each receive a slotted washer therein to be rotatable therein, a counter plate is mounted on another side of said wall of said sponson, said threaded screws are passing through said slotted washers and said counter plate, said threaded screws each have a nut thereon to be tightened against said counter plate where upon a rotation of each of said slotted washers will change the attitude of each said threaded bolts and thereby the horizontal attitude of each of said sponsons.

10. The amphibious aircraft of claim 1 including landing or take-off wheels incuded in said aircraft.

11. The amphibious aircraft of claim 1 including means for braking and steering the aircraft while on the ground.

12. The amphibius aircraft of claim 11, wherein said means for brakin the aircraft is a stand-up plane in front of said V-tail section, a wash of the propeller will impact against said plane and when turning said plane, the wash of said propeller aginst said turned plane will divert said V-tail section into a different direction.
