Description

A wing trailing edge support slide rail fairing

technical field

The utility model belongs to the technical field of aeronautical aerodynamics, and in particular relates to a fairing cover for supporting slide rails at the trailing edge of a wing of a civil aircraft.

Background technique

In order to improve the take-off and landing performance of the aircraft, the front and rear edges of the wing are designed as movable airfoils to change the curvature and area of the wing section. This trailing edge movable airfoil is usually called a flap. In order to support the flap and achieve specific motion requirements, it is necessary to design the corresponding control mechanism and slide rail mechanism. Due to the limitation of the thickness of the wing, the operating mechanism and slide rail of the flap protrude from the lower surface of the wing. In order to reduce the aerodynamic loss caused by the exposed mechanism, a corresponding fairing must be designed.

Contents of the invention

The purpose of the utility model is to provide a wing trailing edge support slide rail fairing, which can reduce the resistance under high-speed cruising under the premise of ensuring the geometric position requirements and the like. The sliding rail fairing described in the utility model is formed by multi-section curved surfaces, and the transition of the curved surfaces is smooth, which will greatly improve its aerodynamic characteristics.

The utility model relates to a wing rear edge supporting slide rail fairing, the slide rail fairing wraps the wing trailing edge flap slide rail inside, the slide rail fairing includes the front section, the middle section and the tail end of the fairing, and the slide rail The overall length of the fairing is L, the length of the front section is L1, the length of the middle section is L2, the inclination angle of the tail end is α, and the front section, middle section and tail end are respectively formed;

The joint A between the front section and the middle section is a movable surface, which is connected by a rotating shaft and can rotate, and the joint surface B between the middle section and the tail end is a fixed connection.

The utility model has the advantages of:

(1) It can better control the contour surface of the slide fairing;

(2) The shape transition is smooth and has good aerodynamic characteristics.

Detailed ways

The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

The present invention relates to a fairing for supporting slide rails at the trailing edge of the wing. The slide rail fairing wraps the flap slide rails at the trailing edge of the wing inside. 4 and the tail end 6, the overall length of the slide fairing is L, the length of the front section is L1, the length of the middle section is L2, the inclination angle of the tail end 6 is α, the front section 2, the middle section 4 and the tail end 6 are formed respectively.

The joint A3 between the front section 2 and the middle section 4 is a movable surface, which is connected by a rotating shaft and can rotate. The joint surface B5 between the middle section 4 and the tail end 6 is fixedly connected, and the inclination angle of the tail end 6 is α.

When installing on the wing, use the frontmost point 1 to determine the installation position of the slide fairing. Since the slide rail fairing will deflect along with the slide rail when the trailing edge flap is opened, the joint A3 between the front section 2 and the middle section 4 is set to be movable, and a rotating shaft is added to enable it to deflect. The fairing middle section 4 and the tail end 6 are fixed together through the joint B5. After forming, the slide rail fairing is installed on the wing along the airflow direction, as shown in Figure 2.
