Embodiment Construction

[0029] combine figure 1 , figure 2 with image 3 , the present invention proposes a horizontal stabilizer, comprising a horizontal stabilizer 1 and an elevator 2, characterized in that:

[0030] The geometric lines of the cross-section of the horizontal stabilizer 1 include chord lines OP and contour lines;

[0031] The outlines include:

[0032] - a straight section FeNe arranged obliquely with respect to the chord line OP;

[0033] - an elliptical arc NeMe, said elliptical arc NeMe connecting said straight line segment FeNe;

[0034] - an elliptical arc MeO connected to an elliptical arc NeMe;

[0035] - an elliptical arc OMi connected to said elliptical arc MeO;

[0036] - an elliptical arc MiNi connected to said elliptical arc OMi;

[0037] - straight line segments NiFi arranged obliquely with respect to the chord line OP;

[0038] - a trailing edge line FiFe, said trailing edge being perpendicular to the chord line OP and arranged symmetrically with respect to th...

Abstract

The invention discloses a horizontal tail vane which comprises a horizontal stabilizer and elevating rudders. Geometric lines of the cross section of the horizontal stabilizer include a chord line OPand contour lines. The contour lines include a straight line section FeNe, an elliptic arc line NeMe, an elliptic arc line MeO, an elliptic arc line OMi, an elliptic arc line MiNi, a straight line section NiFi and a rear edge line FiFe which are sequentially connected with one another. The horizontal tail vane has the advantages that the attitude adjustment efficiency of the horizontal tail vane further can be improved, trim drag can be reduced, and the trim ability of the horizontal tail vane can be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of aircraft equipment, in particular to the technical field of horizontal stabilizers. 【Background technique】 [0002] The horizontal tail (abbreviated as the horizontal tail) is a component that can maintain the stability of the aircraft in flight and control the flight attitude of the aircraft, and is generally located at the rear of the fuselage. Most of the horizontal tail airfoils of existing general aviation aircraft are symmetrical airfoils, and there are few asymmetrical airfoils. There is no horizontal tail design using the V13F airfoil. [0003] V13F airfoil (as attached figure 2 And attached image 3 As shown, where P point is the midpoint of Fe and Fi) is composed of multi-segment splines (straight line, elliptical arc), which has a large lift slope rate, and can provide a larger lift increment. 【Content of invention】 [0004] The purpose of the present invention is to further improve the...
