| 20090188294 | Method and Device for Testing the Quality of a Metallic Coating - A method and a device for determining a quality of a metallic surface of a metallic substrate, for example a steel or steel alloy substrate, are provided. The device includes a mould, a sheet holder and a die, with which the metallic substrate is formed to produce a drawn test surface. The method and device are used to test the quality of the metallic surface of a metallic coating with a view to a later utilization, especially with a view to a later forming, wherein the metallic substrate is formed at least in-an area of a test surface, wherein a main and an additional shape change of the metallic substrate in the area of the test surface assume predetermined values that are related to the later utilization of the metallic substrate, and wherein the quality of the metallic surface is tested on the test surface after forming. | 07-30-2009 |

| 20090194640 | Apparatus system and method for drag reduction - An apparatus, method and system for combining aerodynamic design with engine power to increase synergy between the two and increase climb performance, engine-out performance, and fuel efficiency for a variety of aircraft or the like. | 08-06-2009 |
| 20090289150 | BOUNDARY LAYER CONTROL SYSTEM AND METHODS THEREOF - An airfoil boundary layer control system may be provided. The airfoil boundary layer control system may include at least one airfoil that may include a first surface and a second surface coupled together at a leading edge and a trailing edge; at least one hollow chamber defined within the at least one airfoil; and an aperture defined in the airfoil and positioned substantially near the trailing edge, the aperture coupled in flow communication with the at least one hollow chamber; a pressure source coupled in flow communication with the at least one hollow chamber. | 11-26-2009 |

| 20090076787 | System And Method For Drag Reduction - A system and method for drag reduction allows thrust output, fuel efficiency or both to be maximized. Specifically, a rear portion of a body or motor vehicle may be modified to increase thrust output, fuel efficiency or both by creating a stagnation area, a suction inlet and a convex cusp area formed on the rear portion of the motor vehicle. Increasing the concavity or camber or sharpness of the radius of the stagnation area results in greater local pressure coefficient, which results in greater thrust output. The size and shape of the suction inlet and the convex cusp area will also have an effect on thrust output and fuel efficiency. A width and volume of an airplane fuselage may be increased | 03-19-2009 |
