SK500562019U1 - Horizontal stabilizer device with winglets - Google Patents

Abstract

The horizontal stabilizer of an aircraft with aerodynamic winglets located on an aircraft (1), with wings (2) equipped with aerodynamic winglets (3) and stabilizer (4), can be included in the aviation industry. At the end of the stabilizer (4) there are aerodynamic winglets (5) attached to its fixed part. Winglets (5) have a one-sided or two-sided orientation relative to the plane of the stabilizer (4). The technical solution can be used in civil and military aviation, in all aircraft, which have a classic and less common arrangement of airfoils.

Description

Technical field

The technical solution concerns the solution of an aircraft elevator with aerodynamic wings and belongs to the field of the aviation industry. The solution makes it possible to reduce the induced resistance of the wings during flight, which also causes reduced fuel consumption and thus a longer range.

Prior art

Aircraft manufactured and used today often have winglets at the end of the wings. These are small auxiliary surfaces of various shapes at the end of the aircraft's wing. They direct the air vortices that act on the ends of the wings. As a result, the induced drag resistance of the wings during flight is reduced, which causes reduced fuel consumption and thus a longer range. Aerodynamic wings can also affect the properties of the aircraft during takeoff, can improve its controllability and reduce machine noise. At present, the installation of aerodynamic wings on the wings is common in newer aircraft, but these do not occur on their elevators. Although aerodynamic ailerons minimize turbulence at the wingtips, this effect is not yet used in the case of elevators. The issue of the application of aerodynamic wings is mentioned, for example, in the following literature and patent documents:

The essence of the technical solution

These shortcomings are eliminated by the proposed technical solution, the essence of which lies in the application of the height of the aircraft with aerodynamic wings. The solution makes it possible to reduce the induced resistance of the elevator. As a result, the same advantageous properties are obtained as wings equipped with aerodynamic wings. The advantage is an increase in utility, operational and flight characteristics of the entire machine with a relatively small investment. In FIG. 1 shows an exemplary embodiment of the present device. It shows the overall arrangement of the functional parts of the proposed mechanism. The height of the aircraft with aerodynamic wings is part of the aircraft with aerodynamic wings on the wings. At the end of the elevator has aerodynamic wings, which are attached to a fixed part of the elevator (to the stabilizer). The aerodynamic wings of the elevator have a one-sided or two-sided orientation with respect to the plane of the elevator.

In FIG. 2 shows an example of an embodiment of an elevator with aerodynamic wings with a double-sided orientation with respect to the plane of the elevator.

Examples of embodiments

In FIG. 1 shows an exemplary embodiment of the present device. It shows the overall arrangement of the functional parts of the proposed mechanism. The elevator of an aircraft with aerodynamic wings, is a part of the aircraft 1, with wings 2 equipped with aerodynamic wings 3. At the end of the elevator 4 it has aerodynamic wings 5, which are attached to a fixed part of the elevator 4, i. j. to the stabilizer. The aerodynamic wings 5 have a one-sided or two-sided orientation with respect to the plane of the elevator 4. The advantage of the proposed solution is to further reduce the total induced drag of the aircraft by reducing the induced aerodynamic drag of the elevator 4 during flight, causing further reduction of fuel consumption and thus increased range. aerodynamic

With K 50056-2019 Ul ailerons 5 of the elevator 4 increase their influence on the properties of the aircraft 1 during take-off, they can improve its controllability, reduce its noise and shorten its take-off at takeoff. They suppress turbulence at the ends of the elevator 4 and thus reduce the probability of possible oscillations of individual surfaces of the elevator 4.

Industrial applicability

The device according to the proposed solution can be used in civil aviation and military, in all aircraft, which have a classic and less common way of arranging airfoils.
