Problems solved by technology

[0003] However, the existing aircraft teaching models have fixed structures and single functions. It is difficult to demonstrate different aircraft aerodynamic layouts and wing layouts with one model, which is very inconvenient to use and seriously affects the use of aircraft teaching models in teaching.

Embodiment 1

[0062] Embodiment one: with reference to attached figure 1 , diagram 2-1 , Figure 2-2 , Figure 2-3 , Figure 3-1 and Figure 3-2 , a multifunctional aircraft teaching model, comprising a fuselage 1, a wing 2 and an empennage assembly 3, the wings 2 are symmetrically arranged on the left and right sides of the fuselage 1, the empennage assembly 3 is arranged at the tail end of the fuselage 1, and the empennage assembly 3 comprises a horizontal empennage 4 and a vertical empennage 5, and the wing 2 is connected to the fuselage 1 through a wing variable-sweep structure, and the wing layout form is adjusted by using the wing variable-sweep structure to realize the forward-swept, flat Sweep in the form of wing configurations for straight and swept wings;

[0063] Described wing 2 comprises left wing and right wing, and wing layout form comprises forward-swept wing, straight wing and back-swept wing, when the plane angle between left wing and right wing moves forward 30 ° W...

Embodiment 2

[0068] Embodiment 2: Different from Embodiment 1, when the arcs of the left wing and the right wing are perpendicular to the fuselage 1, the left wing and the right wing are straight, called straight wings, and the wings adopt The aerodynamic layout form of straight wing is called straight wing layout.

Embodiment 3

[0069] Embodiment 3: Different from Embodiment 1 and Embodiment 2, when the plane angle between the left wing and the right wing is adjusted backward by 30°, the left wing and the right wing are swept back, which is called backsweep The aerodynamic layout of the wing adopting the swept wing is called the swept wing layout.

Abstract

The invention discloses a multifunctional airplane teaching model and a manufacturing method thereof. The multifunctional airplane teaching model comprises a fuselage, wings and empennages, the wingsare connected with the fuselage through wing sweepback structures, a horizontal empennage is connected with an upper part of a tail end of the fuselage through a horizontal empennage adjusting structure, and a vertical empennage is connected with the tail end of the fuselage through a vertical empennage slide rail slide block structure; the wing sweep changing structure is used for realizing sweepchanging of the wings of the airplane, the horizontal empennage adjusting structure is used for realizing full-motion change of the horizontal empennage, the vertical empennage slide rail slide blockstructure is used for realizing single-double transformation and V-shaped change of the vertical empennage, a slide block connecting rod structure is used for realizing folding and unfolding of the canard wing, and multiple operations such as sweep changing of the wings of the airplane, folding and unfolding of the canard wing, full-motion change of the horizontal empennage, single-double transformation and V-shaped change of the vertical empennage can be realized on a multifunctional airplane teaching model; and the model has the features of being convenient to use, diversified in structureand function, and simple to operate.

Description

technical field [0001] The invention relates to a teaching model, in particular to a multifunctional aircraft teaching model and a manufacturing method thereof. Background technique [0002] Aircraft aerodynamic layout and wing arrangement form are important basic contents of aviation machinery professional courses. It is difficult to visually display the characteristics of various aerodynamic layouts and wing arrangement forms of aircraft by using multimedia materials such as pictures. Therefore, in order to facilitate students' understanding, the instructor Some aircraft models will be used to assist teaching during the teaching, so that students can learn by observing the actual model, which is more intuitive to use and improves the teaching quality; [0003] However, the existing aircraft teaching models have fixed structures and single functions. It is difficult to demonstrate different aircraft aerodynamic layouts and wing arrangements with one model, which is very inc...
