162 Wind-turbine blade, wind power generator equipped with the same, and design method for the same JP2010238038 2010-10-22 JP2012092657A 2012-05-17 FUKAMI KOJI
PROBLEM TO BE SOLVED: To provide a wind-turbine blade which achieves desired aerodynamic characteristics under condition that the upper-limit value of the chord length on the blade-root side is restricted.SOLUTION: The wind-turbine blade includes a blade body 3 in which the chord length is increased from the blade tip 1b side to the blade root 1a side. The blade body 3 has: a blade tip region 1c provided on the tip side of the blade body and in which the chord length is gradually increased toward the blade root 1a side while having a substantially constant first design lift coefficient; a maximum chord length position 1d located at a position that becomes the maximum chord length on the blade root 1a side and having a second design lift coefficient larger than the first design lift coefficient; and a transition region 1e located between the blade tip region 1c and the maximum chord length position 1d. The design lift coefficient of the transition region 1e is gradually increased from the first design lift coefficient to the second design lift coefficient in a direction from the blade tip 1b side toward the blade root 1a side.
163 Method for easily evaluating drag of model receiving aerodynamic lift in magnetic suspension and balance system JP2007092049 2007-03-30 JP2008249527A 2008-10-16 SAWADA HIDEO
PROBLEM TO BE SOLVED: To provide a technique capable of rationally evaluating aerodynamic forces by substantially improving the efficiency of wind tunnel test and simultaneously eliminating such waste that both a model suspension device and a mechanical balance device, which should not have been required for a wind tunnel provided with a magnetic suspension and balance system, should be separately provided. SOLUTION: In a method for easily evaluating drag of a model receiving aerodynamic lift in a magnetic suspension and balance system, a known external force in a horizontal direction is provided for the model in a state on which lift is not acting to determine the relation of a drag coil current balancing the horizontal external force. A rate of change (B) of the drag coil current to changes in the horizontal external force is quantitatively evaluated on the basis of the relation. The relation between the drag coil current (I drag) and attitude angles (θ) when the attitude angle of the model is changed without providing any external force except gravity is determined. Drag (D) when lift (L) is acting is evaluated on the basis of gravity (mg) acting on the model on the basis of a proposed equation. COPYRIGHT: (C)2009,JPO&INPIT
164 Dynamic lift adjustment structure of current collector JP2012138787 2012-06-20 JP2014003847A 2014-01-09 MITSUMOJI TAKESHI; SATO YUICHI; IKEDA MITSURU
PROBLEM TO BE SOLVED: To provide a dynamic lift adjustment structure of a current collector, which can easily adjust dynamic lift acting on the current collector by reducing aerodynamic force acting on the frame of the current collector with a simple structure.SOLUTION: A turbulent flow transition part 10 allows a laminar flow boundary layer formed on a frame surface 6e by a flow F on the frame surface 6e of a current collector 3 to make a transition to a turbulent flow boundary layer. When there is the turbulent flow transition part 10 on the frame surface 6e, the laminar flow boundary layer on the frame surface 6e makes a transition to the turbulent flow boundary layer, and the flow F is disturbed by the turbulent flow transition part 10, causing active momentum exchange. Thus, the flow F is hardly separated from the frame surface 6e, and the separation of the flow F from the frame surface 6e is retarded. As a result, a separation point of the flow F is moved backward to the downstream side so that Karman vortices generated behind a frame 6 are weakened, and aerodynamic force Lacting on the frame 6 is reduced. Thereby, dynamic lift Lacting on the current collector 3 is adjusted.

168 DEVICE AND METHOD FOR INCREASING THE AERODYNAMIC LIFT OF AN AIRCRAFT EP11767986.0 2011-10-05 EP2625096A1 2013-08-14 WEBER, Carsten; FISCHER, Markus; GROTE, Arne; RADESPIEL, Rolf; DREYER, Martin
A lift arrangement for an aircraft (2) comprises an aircraft fuselage section with an outside (3), an aerodynamic lift body (6, 8)attached to the aircraft fuselage section and extending from the aircraft fuselage section outwardly, and a pair of movably held add-on bodies (12)arranged upstream of a leading edge (14) of the aerodynamic lift body (6, 8). The add-on bodies(12) comprise an aerodynamically effective surface and are equipped with incoming airflow to generate vortices (18) that impinge on the aerodynamic lift body (6, 8), thus leading to an increase inlift on the aerodynamic lift body (6, 8). Consequently it becomes possible with simple means to effectively influence lift generation on a lift body (6, 8), in particular to compensate for loss of lift as a result of icing. Preferably, the add-on bodies are moveable, and, when operational conditions do not require the use of said add-on bodies, can be moved to a neutral position in which they do not project into the flow around the aircraft, and are thus not effective from the point of view of fluid dynamics.

172 High lift force-generating device, wing and slat JP2010030075 2010-02-15 JP2011162154A 2011-08-25 HAYASHI KENSUKE; ISHIHARA KENYA; YAHATA YUSAKU; HIRAI MAKOTO
PROBLEM TO BE SOLVED: To provide a high lift force-generating device and a wing, which can suppress generation of aerodynamic noise while suppressing increase in body weight. SOLUTION: A recess and projection part 20 is formed in a bottom plate 7 extending rearward in a lower surface of a slat 3, so that a position in which air flow flowing along the surface of the slat 3 is exfoliated from the bottom plate 7 to generate a vortex is made uneven in the air flow direction. Thereby, the vortex generated in a recess 20A and the vortex generated in a projection 20B are short in correlation with each other, and the vortices are hardly connected to each other, and becomes the independent vortexes, so that the generated vortex is weak in strength, which can reduce the pressure fluctuation on a body surface, and suppress generation of the aerodynamic sound.
