Active drag and thrust modulation system and methods
View Patent ↗A vehicle traveling through an environmental media such as air experiences drag. The drag is actively modulated by energy beams which may either increase or decrease the drag. The energy beams may provide either a chemical, acoustic or electromagnetic energy at a transition region between turbulent and laminar flows or at the leading edge of a laminar flow or in the direction of a crosswind in order to facilitate the respective increase or decrease in drag. If the vehicle is a sailing ship, areas of the sails are selectively roughened or widened to enhance the thrust derived from the wind. Furthermore, the keel or hull of the sailing ship may be modified to improve the hydrodynamic characteristics of the sailing ship. If the vehicle is an automobile, the tires or road surface may be selectively heated to improve the traction of the automobile. Furthermore, the energy beams may be used to facilitate atomization of the air/fuel mixture prior to combustion in an internal combustion engine thereby improving the thrust of provided to the vehicle. Energy beams may be used to generate virtual extensions of a vehicle to enhance traveling efficiency.
1. A method of enhancing atomization of a fuel in an air environment comprising the steps of:
injecting the fuel in the form of a fuel spray into the air environment to form a fuel/air mixture;
directing an energy beam into the fuel/air mixture, the energy beam facilitating atomization of the fuel in the fuel/air mixture, wherein the energy beam is a ultrasonic energy beam;
determining an amount of the fuel sprayed by said step of injecting; and
adjusting a frequency of the ultrasonic energy beam in response thereto.
