Embodiment Construction

[0031] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] Such as Figure 1-10 Shown, comprise: fuselage 2 and the wing 1 (wing level installation) that is installed on the fuselage and empennage 3, form the through hole that is used to adjust the center of gravity of catapult glider model in the front part of fuselage (the figure not shown) and a hook for ejection (not shown).

[0033] The dihedral of the traditional aircraft adopts a two-stage one-fold wing, such as figure 1 As shown, the assembly accuracy of this kind of wing is not easy to improve, it is easy to install crookedly, and the assembly is difficult. In the present invention, the wing is installed in three sections, and the wing is made up of the middle section 1-2 of the wing and 2 wingtips 1-1, as figure 2 As shown, the middle section of the wing is installed on the fuselage through a mortise and tenon mechanism, which mak...

Abstract

The invention discloses an ejection type glider model, which comprises a glider body, and a wing and an empennage which are installed on the glider body. The wing comprises a middle section and two wing ends that are installed on two ends of the middle section, respectively. A reverse angle on the wing ends is 15-25 degrees, wherein a stepped edge is formed on the upper surface of the wing in the length direction of the wing and located at a point of 45-55% of the length of a wing chord, and the height of the stepped edge is 4-6% of the length of the wing chord. The empennage comprises a first empennage and a second vertical empennage. The first empennage is installed on the glider body at an angel of 2-3 degrees that is formed by rotating the first empennage with the glider body as a central axis and with a horizontal level as a starting point. The lower end of the second empennage is fixed on the upper surface of the first empennage. Both sides of the second empennage are fixed on the glider body. The stepped edge makes the wing become a stepped wing, increasing lift-drag ratios and stalling angles of the wing.

Description

technical field [0001] The invention belongs to the technical field of aircraft for scientific and technological activities, and in particular relates to a catapult glider model. Background technique [0002] Catapult models have a long history as toys or as teaching aids for beginners in aviation. The hovering method of the traditional catapult gliding aircraft model generally adjusts the rudder or the ailerons to make the aircraft turn and circle. This method makes the flight control of the aircraft complicated and it is difficult to analyze the state during ejection. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a catapult glider model, which is controlled to turn and hover through the tail. [0004] The purpose of the present invention is achieved through the following technical solutions. [0005] A catapult gliding aircraft model, comprising: a fuselage and a wing and an empennage m...
