Abstract

A propulsion system coupled to a vehicle. The system includes a convex surface, a diffusing structure coupled to the convex surface, and at least one conduit coupled to the convex surface. The conduit is configured to introduce to the convex surface a primary fluid produced by the vehicle. The system further includes an intake structure coupled to the convex surface and configured to introduce to the diffusing structure a secondary fluid accessible to the vehicle. The diffusing structure comprises a terminal end configured to provide egress from the system for the introduced primary fluid and secondary fluid.

First claim

What is claimed is:

1. A propulsion system coupled to a vehicle, the system comprising:
a convex surface having a perimeter and a plurality of recesses;
a diffusing structure coupled to the convex surface;
at least one conduit coupled to the convex surface and configured to introduce to the convex surface via multiple nozzles distributed along the entirety of the perimeter a primary fluid produced by the vehicle; and
an intake structure coupled to the convex surface and configured to introduce to the diffusing structure a secondary fluid accessible to the vehicle, wherein the nozzles are downstream of the intake structure, and wherein the diffusing structure comprises a terminal end configured to provide egress from the system for the introduced primary fluid and secondary fluid.

2. The system of claim 1 , wherein the at least one conduit comprises an array of nozzles arranged in at least one of a curved orientation, a spiraled orientation, and a zigzagged orientation.

3. The system of claim 1 , wherein the intake structure is asymmetrical.

4. A propulsion system coupled to a vehicle, the system comprising:
a diffusing structure;
at least one conduit coupled to the diffusing structure and configured to introduce to the diffusing structure a primary fluid produced by the vehicle; and
an asymmetrical intake structure coupled to the diffusing structure and configured to introduce to the diffusing structure a secondary fluid accessible to the vehicle, wherein the diffusing structure comprises a terminal end configured to provide egress from the system for the introduced primary fluid and secondary fluid, and wherein the intake structure comprises first and second lateral opposing edges, and the first lateral opposing edge has a greater radius of curvature than the second lateral opposing edge.

5. The system of claim 4 , wherein the at least one conduit comprises an array of conduits arranged in at least one of a curved orientation, a spiraled orientation, and a zigzagged orientation.

6. The system of claim 4 , further comprising a convex surface, wherein the at least one conduit is configured to introduce to the convex surface the primary fluid produced by the vehicle.

7. A propulsion system coupled to a vehicle, the system comprising:
a diffusing structure;
at least one conduit coupled to the diffusing structure and configured to introduce to the diffusing structure a primary fluid produced by the vehicle; and
an asymmetrical intake structure coupled to the diffusing structure and configured to introduce to the diffusing structure a secondary fluid accessible to the vehicle, wherein the diffusing structure comprises a terminal end configured to provide egress from the system for the introduced primary fluid and secondary fluid, and wherein the intake structure comprises first and second opposing edges, and the second opposing edge includes a curved portion projecting toward the first opposing edge.

8. The system of claim 7 , wherein the at least one conduit comprises an array of conduits arranged in at least one of a curved orientation, a spiraled orientation, and a zigzagged orientation.

9. The system of claim 7 , further comprising a convex surface, wherein the at least one conduit is configured to introduce to the convex surface the primary fluid produced by the vehicle.
