Embodiment Construction
[0019] figure 1 Schematically showing a perspective view of an airfoil test piece of the present invention, figure 2 schematically shows figure 1 A partial enlargement of the plane.
[0020] combine figure 1 with figure 2 , the airfoil test piece includes a position adjustment assembly 100 , a piccolo test piece 200 and an airfoil casing 300 . Wherein, the position adjustment assembly 100 is used to adjust the position of the piccolo test piece 200 . Wherein, the so-called piccolo test piece 200 is a test element processed to simulate the real piccolo in the anti-icing chamber of the wing in the ice wind tunnel test of the anti-icing system. Here, what is put into the ice wind tunnel for testing is a specially designed and manufactured airfoil test piece, and the airfoil shell 300 is a test piece that simulates the airfoil of a real wing slat. The reason why the corresponding piccolo test piece is set for the real piccolo and the airfoil shell is set corresponding to t...

The invention discloses a wing type test piece which comprises a wing type shell, a flute tube test piece and a location regulating assembly, wherein the wing type shell comprises a first end wall part, a second end wall part opposite to the first end wall part, and a side wall part, and the first end wall part, the second end wall part and the side wall part form a holding cavity; the flute tube test piece is held in the holding cavity and used for preventing ice of the wing type shell, the location regulating assembly comprises a first cover board and a second cover board which are used for fixing the flute tube test piece between the first cover board and the second cover board; the first cover board is movably arranged on the first end wall part, the second cover board is movably arranged on the second end wall part so that the flute tube test piece has at least two space locations relative to the wing type shell. According to the invention, the position of the flute tube test piece in an anti-icing cavity of the wing type shell can be regulated so that the flute tube test piece can be conveniently calculated and verified to be in an optical position or close to the optical position in the anti-icing cavity.
Description
technical field [0001] The invention relates to the technical field of ice wind tunnel tests of an aircraft hot gas anti-icing system, in particular to an airfoil test piece. Background technique [0002] In order to provide data support for the calculation model and check the effectiveness of the anti-icing system, etc., the piccolo test piece is usually designed and fixed into the airfoil test piece for ice wind tunnel test. However, in the ice wind tunnel tests of the existing aircraft hot gas anti-icing system, the position of the piccolo test piece is fixed at a certain position in the anti-icing chamber of the airfoil test piece, that is, the piccolo test piece is inactive. [0003] As we all know, in the development stage of the anti-icing system, the position of the flute tube test piece in the anti-icing chamber, the size, angle, number of rows, hole spacing, row spacing and other parameters of the flute tube test piece need to be comprehensively evaluated to obtai...
