| 20090088972 | VEHICLE-BASED AUTOMATIC TRAFFIC CONFLICT AND COLLISION AVOIDANCE - Systems and methods for providing vehicle-centric collision avoidance are disclosed. In one embodiment, a method includes determining a first flight trajectory for a first aircraft. The method also includes determining a second flight trajectory for a second aircraft. A distance between the first aircraft and the second aircraft at a first closest point of approach (CPA) is predicted. The predicted closest point of approach is then compared to a separation perimeter layer. The separation perimeter layer is configured to provide a minimum separation distance from the first aircraft to the second aircraft. When the predicted closest point of approach breaches the separation perimeter, the first flight trajectory is altered to provide collision avoidance. | 04-02-2009 |

| 20100040458 | AXIAL FAN CASING DESIGN WITH CIRCUMFERENTIALLY SPACED WEDGES - An axial fan assembly including a casing wall with a forward facing step formed therein. Formed on the surface of the step is a plurality of circumferentially spaced wedges which are formed and positioned so as to reduce the swirl flow within the clearance gap between the fan rotor and casing. The wedges are formed so the swirling backflow first encounters a circumferentially tapered face and then an abrupt axially oriented face, thereby substantially removing the swirl component. The wedges have a favorable effect on the flow stability of the fan, thereby extending its operating range. Variations include a fan rotor with a rotating shroud with an outwardly extending portion overlapping the step, and a bellmouth piece at the casing inlet. | 02-18-2010 |
| 20100068028 | REDUCED TIP CLEARANCE LOSSES IN AXIAL FLOW FANS - An axial fan assembly including a casing wall with a forward facing step formed therein and a fan rotor with blade tips, each having an aft facing step which radially overlaps the casing step so as to reduce the clearance backflow loss in the assembly. A vane is attached to the suction side of each of the blade tips with the vane having an aft facing step which radially overlaps the casing forward facing step to promote further reduction of clearance backflow. Variations on the invention include the option of an additional inlet bellmouth piece that further restricts the clearance flow and wedges integral to the casing step to improved flow stability. | 03-18-2010 |
| 20100119366 | OUTLET GUIDE VANES FOR AXIAL FLOW FANS - An improved outlet guide vane system is disclosed for axial flow fans. Construction details are described which reduce losses in the end wall regions of the vanes, particularly for axial flow fans operating at low flow coefficient with strong localized swirl associated with upstream rotor tip clearance flows. In the preferred embodiment, the vane spanwise airfoil stacking line is approximately straight, while leaning circumferentially toward the incoming swirl flow over the majority of the radial span. The stacking line then curves abruptly in the opposite direction over the radially outboard spanwise portion, so as to lean away from the incoming swirl at the vane tip station. The radially outboard portion of the vanes simultaneously include a gradual increase in vane stagger angle, vane camber angle and vane chord. The vane may also include an axial sweep component. | 05-13-2010 |

The flow is then driven upward through a nozzle and discharged into the trailer. The nozzle shape graduates from a circular cross-section to a wide-aspect ratio rectangular cross-section, while turning through 90°. The preferred choice of axial flow fan for the invention is the vane-axial type incorporating outlet guide vanes. Provision is made for a single fan-nozzle configuration which may be either centered or transversely off-set with respect to the evaporator coil. An additional option provides for an arrangement with a pair of side-by-side fan-nozzles. | 01-20-2011 |
