Abstract

A fluid medium vehicle is provided which has a main body and at least one engine attached to the main body. The engine is configured to provide thrust parallel to a thrust axis passing through the main body. A plurality of foils is moveably attached to and extends outwardly from the main body. The plurality of foils is arranged in pairs. Each pair of foils extends from the main body along opposite ends of one of a plurality of foil axes. Each foil axis is perpendicular to the thrust axis, and each foil is constructed as an independently positionable control surface and as an independently controllable propulsion device.

First claim

What is claimed is:

1. A vehicle for use in a fluid medium, said vehicle comprising:
an elongated main body with a detachable nose section capable of being configured with sensors, said nose section in alignment with a longitudinal axis of said elongated main body;
a payload section encompassed by said elongated main body, said payload section capable of housing at least one deployable payload with said payload section having an underwater camera and sonar at a port on a first end of said payload section as well as at least two adjacent deployment tubes, each of said deployment tubes having an open end covered by a releasable cap wherein said releasable cap can eject upon deployment of the deployable payload;
two spaced apart engines affixed to a rear portion of said main body opposite said nose section with each said engine including a thruster configured to provide thrust parallel to the longitudinal axis of said main body as well as being capable of steering a direction of said main body at alternative angles relative to a longitudinal axis of said main body;
at least four coplanar and bi-modal flapping foil propulsors moveably attached to and extending outwardly from said main body, said at least four coplanar flapping foil propulsors arranged in pairs, each pair extending from said main body along opposite ends of one of a plurality of foil axes with each foil axis perpendicular to the longitudinal axis of said main body wherein each of said bi-modal flapping foil propulsors can independently oscillate in a flapping motion to generate propulsion forces and as independent control surfaces;
a pair of side scan sonars longitudinally and releasably affixed to a longitudinal exterior of said main body; and
a retractable buoy tethered to said main body and configured to provide at least one of command and control communications between said vehicle and remote operators of said vehicle, image data collection remote from said vehicle and sensor data remote from said vehicle.
