Drag experienced by a vehicle traveling through an environmental media, such as air or water, may be modified by one or more energy beams which may increase or decrease drag. Environmental media may be adjusted by microwave, chemical, ultrasonic, acoustic (including subsonic, sonic, or ultrasonic),
Drag experienced by a vehicle traveling through an environmental media, such as air or water, may be modified by one or more energy beams which may increase or decrease drag. Environmental media may be adjusted by microwave, chemical, ultrasonic, acoustic (including subsonic, sonic, or ultrasonic), or electromagnetic energy. One or more energy beams may be directed toward a transition region between turbulent and laminar flow, at the leading edge of a laminar flow, or in the direction of a crosswind.

1. A drag modification system for a vehicle in an environmental media, the system comprising: a first transducer configured to respond to first signal portion and configured to emit a first energy beam at a first angle with respect to a boundary layer adjacent to a first surface portion of a vehicle
1. A drag modification system for a vehicle in an environmental media, the system comprising: a first transducer configured to respond to first signal portion and configured to emit a first energy beam at a first angle with respect to a boundary layer adjacent to a first surface portion of a vehicle, into a transitional section between a laminar flow and a turbulent flow of the boundary layer; anda second transducer configured to respond to a second signal portion and configured to emit a second energy beam at a second angle with respect to a boundary layer adjacent to a second surface potion of the vehicle, into a transitional section between a laminar flow and a turbulent flow of the boundary layer,wherein the first or second transducer is configured to change a drag on portion of the vehicle. 2. The system of claim 1 wherein the environmental media substantially comprises air, water, or a combination thereof. 3. The system of claim 1 wherein the first or second transducer is positionable on the front or rear of the vehicle. 4. The system of claim 1 wherein the first angle of the first transducer or the second angle of the second transducer is adjustable. 5. The system of claim 1 wherein at least the first or second surface portion has a profile that is adjustable. 6. The system of claim 1 wherein the first or second signal portion is selectively activatable. 7. The system of claim 1 wherein the first or second energy beam is alterable in response to a vehicle velocity. 8. The system of claim 1 wherein the first or second signal portion defines the first or second angle. 9. The system of claim 1 wherein the first or second angle is adjustable to increase or decrease drag. 10. The system of claim 1 wherein the first and second angles are substantially equal. 11. A drag modification system for a vehicle in an environmental media, the system comprising: a first transducer configured to emit a first energy at a first angle with respect to a boundary layer adjacent a surface of the vehicle, and between a laminar flow and a turbulent flow associated with the surface of the vehicle; anda second transducer configured to emit a second energy at a second angle, the second angle being different than the first angle,wherein the first or second transducer is configured to modify a drag exerted on the vehicle. 12. The system of claim 11 wherein the first or second transducer is attached to a front or rear potion of the vehicle. 13. The system of claim 11 wherein energy is emitted responsive to a signal controlled by an operator of the vehicle. 14. The system of claim 11 wherein the energy is altered based upon a vehicle velocity or direction. 15. The system of claim 11 wherein the emitted energy promotes turbulent or laminar flow flow. 16. The system of claim 11 wherein the first energy is substantially equal to the second energy. 17. A drag modification system for a vehicle in an environmental media, the system comprising: a first transducer configured to emit a first beam at a first angle with respect to a boundary layer adjacent a surface of the vehicle, into a transitional section of the boundary layer formed by the environmental media upon a surface of the vehicle; anda second transducer configured to emit a second beam at a second angle, the second angle being offset from first angle,wherein a drag on a portion of the vehicle is changed by the first or second beam by adjusting the environmental media. 18. The system of claim 17 wherein the first angle of the first beam or the second angle of the second beam is changed by an operator of the vehicle or a computer associated with the vehicle. 19. The system of claim 17 wherein the first or second beam is changed based upon a movement of environmental media with respect to the vehicle. 20. The system of claim 17 wherein the first or second transducer is configured to adjust the first or second beam responsive to vehicle velocity, vehicle pitch, vehicle yaw, turbulence, air density, temperature, humidity, wind speed, wind direction, or altitude.
