Embodiment Construction

[0014] Specific embodiments of the present invention: as figure 1 Shown, a kind of double-sweep type full-motion deflection plane tail, comprises flat tail inner side 2, flat tail outer side 3 and rear segment sweep angle 4, is characterized in that it also includes the front segment swept wing 1 that is positioned at the front part of the flat tail and is formed by the front segment rear The front sweep angle 5 formed by the swept wing 1.

[0015] The shape of the leading edge of the swept wing 1 in the front section is sharp, and an ordered vortex with sufficient energy is generated at a large angle of attack to suppress the flow separation of the main airfoil of the outer section of the flat tail; the sweep angle 5 of the front section of the flat tail and the sweep angle of the rear section 4 are not equal, and the sweep angle 5 of the leading edge of the horizontal tail is generally 50° to 70°.

Abstract

The invention relates to the technical field of horizontal tail design of an aircraft, in particular to a horizontal tail of a double-swept back full dynamic deflection aircraft. The horizontal tail comprises a horizontal tail internal side (2), a horizontal tail external side (3) and a rear segment rear sweep angle (4); the horizontal tail is characterized by further comprising a front segment rear sweep wing (1) located at the front part of the horizontal tail and a front segment rear sweep angle (5) formed by the front segment rear sweep wing (1). The horizontal tail provided by the invention can effectively inhibit airflow separation on the main wing surface of the horizontal tail, so that the stalling area of the main wing surface of the horizontal tail is reduced, the pitch control performance of the horizontal tail under large deflection is improved, and the reduction of the design area of the horizontal tail is favored.

Description

technical field [0001] The invention relates to the design field of a horizontal tail of an aircraft, in particular to a double-sweep type full-motion deflection horizontal tail of an aircraft. Background technique [0002] The horizontal tail (hereinafter referred to as the horizontal tail) is an important aerodynamic component in the aircraft components, which is used to trim the aircraft and maintain the stability and maneuverability of the aircraft in the pitch direction. Generally, it can be divided into two layout forms: horizontal stabilizer plus elevator and full-motion horizontal tail. The conventional full-motion stabilizer has two airfoils, which are generally located behind the wing and symmetrically distributed on both sides of the plane of symmetry of the aircraft. The entire stabilizer can rotate around the axis of the stabilizer for pitch control of the aircraft. Its plane shape is generally trapezoidal, the leading edge is a single swept angle, and the ...
