Embodiments of the present invention and its advantages are best understood by referring to FIGS. 1 through 4 of the drawings, like numerals being used for like and corresponding parts of the various drawings.

In some cases, sonar buoys may be deployed by being dropped from a helicopter or Anti-Submarine Warfare (ASW) aircraft. In other cases, a helicopter may lower an active dipping sonar into water while hovering at a set location. In some cases, sonar buoys may be dropped for one time use, following which they sink.

The teachings of the disclosure recognize that it would be desirable to provide an unmanned aerial vehicle based sonar buoy (active or passive) that may be deployed from a surface vehicle to a specified remote location on an "as needed" basis. FIGS. 1 through 4 below illustrate an unmanned aerial vehicle based sonar buoy and system according to the teachings of the disclosure.

FIGS. 1 and 2 illustrate a surface vehicle 100 according to certain embodiments. Surface vehicle 100 includes one or more launch tubes 110. Launch tubes 110 may be utilized to deploy unmanned aerial vehicle based sonar buoy 120 described below.

In some embodiments, surface vehicle 100 may be any vehicle capable of traveling on water. In one embodiment, surface vehicle 100 may be a manned ship, warship, boat, and the like. In some embodiments, surface vehicle 100 may be an unmanned surface vehicle (USV). Surface vehicle 100 may be any size capable of carrying at least one launch tube 110. Surface vehicle 100 may be propelled by any propulsion means, including, but not limited to, electric motor(s), gasoline/diesel motor(s), and/or wind.

FIG. 3 illustrates an unmanned aerial vehicle based sonar buoy 120, according to certain embodiments. Unmanned aerial vehicle based sonar buoy 120 includes wings 130, sonar 140, a fuselage 145, an engine 150, and a guidance computer 160. Wings 130 and engine 150 may be coupled to sonar 140 and/or fuselage 145. Unmanned aerial vehicle based sonar buoy 120 may be deployed by surface vehicle 100 via launch tubes 110.

Wings 130 may be any appropriate wings to allow unmanned aerial vehicle based sonar buoy 120 to fly once launched from launch tubes 110. In some embodiments, wings 130 fold into a shape to allow unmanned aerial vehicle based sonar buoy 120 to fit into launch tubes 110. Wings 130 may then automatically deploy to the appropriate position for flight immediately after unmanned aerial vehicle based sonar buoy 120 is launched from launch tubes 110. In certain embodiments, wings 130 remain attached to unmanned aerial vehicle based sonar buoy 120 once it lands in water. In other embodiments, wings 130 may automatically detach from unmanned aerial vehicle based sonar buoy 120 once it lands in water.

Sonar 140 may be any appropriate active or passive sonar. Sonar 140 is any appropriate shape that will allow unmanned aerial vehicle based sonar buoy 120 to fit in launch tubes 110. In some embodiments, sonar 140 is tube-shaped and forms some or all of fuselage 145 of unmanned aerial vehicle based sonar buoy 120. In some embodiments, sonar 140 may be disposed within fuselage 145.

Engine 150 is any appropriate engine to propel unmanned aerial vehicle based sonar buoy 120 through flight. In some embodiments, engine 150 is an electric engine. In other embodiments, engine 150 is a gasoline engine. Engine 150 is coupled to a propeller that is any appropriate shape to allow unmanned aerial vehicle based sonar buoy 120 to fit inside launch tubes 110. In certain embodiments, engine 150 remains attached to unmanned aerial vehicle based sonar buoy 120 once it lands in water. In other embodiments, engine 150 may automatically detach from unmanned aerial vehicle based sonar buoy 120 once it lands in water.

In operation, unmanned aerial vehicle based sonar buoy 120 is stored in a launch tube 110 on surface vehicle 100 prior to being deployed. When it is desired to deploy unmanned aerial vehicle based sonar buoy 120, unmanned aerial vehicle based sonar buoy 120 is launched from launch tube 110 using any appropriate means. In one embodiment, for example, a small rocket motor 170 may be utilized to expel unmanned aerial vehicle based sonar buoy 120 from launch tube 110. In some embodiments, rocket motor 170 may be detachably coupled to unmanned aerial vehicle based sonar buoy 120 and may detach from unmanned aerial vehicle based sonar buoy 120 immediately after being launched from launch tube 110.

Immediately after being launched from launch tube 110, wings 130 of unmanned aerial vehicle based sonar buoy 120 may unfold and engine 150 starts. Unmanned aerial vehicle based sonar buoy 120 is then airborne. Guidance computer 160, which may include a Global Positioning System (GPS) or any other navigational system, guides unmanned aerial vehicle based sonar buoy 120 to a predetermined destination by controlling wings 130, engine 150, and other control surfaces of unmanned aerial vehicle based sonar buoy 120. Guidance computer 160 may also include a transceiver for receiving commands from an operator and for sending information back to the operator.

Once unmanned aerial vehicle based sonar buoy 120 arrives at the predetermined location, it may proceed to land in the water. Once in the water, sonar 140 of unmanned aerial vehicle based sonar buoy 120 functions as a typical active or passive sonar in order to locate objects under the water such as submarines. In some embodiments, wings 130 and engine 150 may automatically detach from sonar 140 once unmanned aerial vehicle based sonar buoy 120 lands in the water so as to not hinder sonar 140.

In some embodiments, unmanned aerial vehicle based sonar buoy 120 may include a mechanism by which to drop sonar 140 into the water at the predetermined location. For example, as illustrated in FIG. 4, wings 130, engine 150, and guidance computer 160 may be attached to fuselage 145 that is separate from sonar 140. Sonar 140 may be detachably coupled to fuselage 145 so that it may detach and fall into the water on command. In some embodiments, unmanned aerial vehicle based sonar buoy 120 may crash into the water and sink once dropping sonar 140. In other embodiments, unmanned aerial vehicle based sonar buoy 120 may return to surface vehicle 110 once dropping sonar 140 into the water.

In some embodiments, unmanned aerial vehicle based sonar buoy 120 may be launched from a launch tube 110 that is coupled to a stationary object on land, or any vehicle other than surface vehicle 100. For example, in some embodiments launch tube 110 may be coupled to an aircraft. In other embodiments, launch tube 110 may be coupled to a fixed object on land. In other embodiments, launch tube 110 may be coupled to a vehicle that travels on land such as trucks, cars, tanks, military vehicles, and the like. The disclosure anticipates unmanned aerial vehicle based sonar buoy 120 being launched from any suitable launch tube 110 regardless of its location.
