    摘要: The present invention relates to a method for improving the precision of wind tunnel measurements, particularly to correct the influence of a suspension device, wherein a model, particularly an aircraft model, being introduced into a wind tunnel on the suspension device, which has multiple suspension wires, and at least one sleeve being attached to each suspension wire, having the following steps: performing at least two measurements with identical model configuration with at least one effective diameter and/or with the suspension wire diameter in each case to ascertain at least two raw measured values and ascertaining a corrected final measured value for the model from at least two measured values. According to a first embodiment variation of the method according to the present invention, for example, in the course of detecting raw measured values of the air resistance coefficient of the model, the effective diameter of the suspension wires is reduced in at least three steps by removing sleeves which have been pushed on. A final measured value of the air resistance coefficient, which has been corrected for the influence of the suspension device and the interference between model and suspension device, may be ascertained from the raw measured values through interpolation. According to a further variation, the correction is performed through difference calculation of only two raw measured values, one of the raw measured values being ascertained with the suspension wire diameter without sleeves pushed on. The method is suitable for correcting all aerodynamic characteristic variables measurable in the wind tunnel. Furthermore, the present invention relates to a device for performing the method.

    摘要: An auxiliary flap is movably arranged on a planar trailing edge of an aerodynamic element such as a wing, rudder, stabilizer, or flap. The auxiliary flap is rotatable and/or slidable relative to the aerodynamic element, to move selectively into three positions. In a first position, a free edge of the auxiliary flap protrudes into an airflow boundary layer on one side of the aerodynamic element, to decrease lift. In a second position, a free edge of the aerodynamic element protrudes into an airflow boundary layer on the other side of the aerodynamic element, to increase lift. In a third neutral position, the auxiliary element does not protrude into either boundary layer, so as not to influence lift. The auxiliary flap is simple and rapidly acting. The flap protrudes substantially perpendicularly into the boundary layer flow. The auxiliary flap has a planar plate shape.

    摘要: A method for improving the precision of wind tunnel measurements provides a correction to reduce the influence of a suspension device. A model, such as an aircraft model, is held by the suspension device in a wind tunnel and has multiple suspension wires. By attaching one or more sleeves to each suspension wire, a plurality of measurements with identical model configuration are capable of providing data for extrapolating corrected measurement values for a plurality of aerodynamic characteristic variables measurable in a wind tunnel. Examples of sleeves include a slit along the sleeve length and an inner diameter of the sleeves selected such that the sleeve is capable of being pressed onto and removed from a suspension wire or a sleeve of lesser outer diameter.

    摘要: An engine pod for an aircraft has one side which features several fin-shaped vortex generators such that the overall vorticity field generated by the vortex generators extends over an increasing airfoil area in the wingspan direction as the angle of attack increases. The first vortex generator lies within a positioning corridor that is situated between two boundary lines. The origin and end points, respectively, of the first boundary line are the points on the circumference of the engine pod with the circumferential engine pod angle phi=35 degrees and 25 degrees and the longitudinal engine pod coordinate X=L/4 and L·⅔. The origin and end points, respectively, of the second boundary line are the points on the circumference of the engine pod with the circumferential engine pod angle phi=90 degrees and 55 degrees and the longitudinal engine pod coordinate X=L/4 and L·⅔.
