Embodiment Construction

[0025] The technical scheme of the present invention will be further described below in conjunction with the drawings.

[0026] Such as Figure 1-9 As shown, the fuselage 2 is equipped with a wing 1 (wing mounted horizontally) and a tail 3, and a through hole (not shown in the figure) for adjusting the center of gravity of the ejection glider model is formed in the front of the fuselage and for ejection The hook (not shown in the figure).

[0027] In traditional aircraft, the contra-angle adopts a two-section one-fold wing, such as figure 1 As shown, this kind of wing is easy to skewed and difficult to assemble. In the present invention, the wing adopts a three-stage installation, and the wing is composed of the middle section of the wing 1-2 and two wing tips 1-1, such as figure 2 As shown, the middle section of the wing is installed on the fuselage through a tenon and tenon mechanism, which makes the connection between the wing and the fuselage very simple and accurate. The man...

Abstract

The invention discloses a wing applied to a pop-up type glider model. The wing is composed of a wing middle section and two wing tips, wherein the two wing tips are fixedly installed at the two ends of the wing middle section respectively, the dihedral angle of the wing tips is 15-25 degrees, the rear edge of the wing tip located at the left end of the wing middle section has misalignment by 0.8-1 mm in the vertical direction, and the rear edge of the wing tip at the right end of the wing middle section has misalignment by 0.8-1 mm in the vertical direction; a stepped table is formed on the upper surface of the wing in the length direction of the wing and located at the position of 45-55% of the length of a wing chord, and the step height of the stepped table accounts for 4-6% of the length of the wing chord. Due to the misaligned installation of the wing tips, the pop-up type glider model ascends perpendicularly with stable ascending trails, and the climbing height can exceed 30 meters. The stepped table makes the wing stepped, the life-drag ratio of the wing is increased, and the stalling attack angle of the wing is increased.

Description

Technical field [0001] The invention belongs to the technical field of scientific and technological activity aircraft, and specifically relates to a wing applied to a catapult glider model. Background technique [0002] The catapult glider model has a long history as a toy or a teaching aid for beginners in aviation. Traditional catapult gliders cannot automatically enter when encountering updrafts, and cannot automatically leave when encountering downdrafts, which is not conducive to the extension of the aircraft's empty time. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a wing applied to a catapult glider model, which can increase the empty time of the catapult glider model. [0004] The purpose of the present invention is achieved through the following technical solutions. [0005] A wing applied to a model of a catapult glider, which is composed of a middle section of the wing and two wing tips...
