Description
Technical Field
The invention relates to a model airplane, in particular to a plastic model airplane with arch-shaped wing rubber band propellers.
Background
The rubber-band propeller model airplane drives a propeller through a rubber band, and the propeller drives the airplane to lift off and take off. The earliest rubber-band propeller model aircraft had wings made of wood material, rubber bands outside the aircraft body, poor lift and smoothness, and poor appearance; later, the fuselage is changed into a tubular shape, the rubber band can be arranged in the fuselage, the wing empennage is arranged on the fuselage through the support and can be made into a streamline shape, although the fuselage is attractive, the wing empennage is heavy, the lifting force is influenced, the manufacturing is troublesome, and the fuselage is not convenient for children of low ages to manufacture manually.
Disclosure of Invention
The invention aims to overcome the defect that the existing rubber-band propeller model airplane is lack of lift force, is troublesome to manufacture and is not beautiful in appearance, and provides a plastic arch-type wing rubber-band propeller model airplane which can be used for molding the section of a wing empennage into a model airplane with streamline characteristics so as to improve the lift force and the smoothness.
The purpose of the invention is realized by the following mode: the plastic type arched wing rubber band propeller model airplane comprises a fuselage, wings, a horizontal tail wing, a rubber band and a propeller, wherein the fuselage is a cylindrical body, a front plug and a rear plug are arranged at two ends of the fuselage, an inclined long slit is formed at the front end of two sides of the fuselage, an inclined short slit is formed at the rear end of the fuselage, the wings and the horizontal tail wing are elastic flaky bodies and are inserted into the fuselage through the inclined long slit and the inclined short slit, plastic strips are arranged below the wings and the horizontal tail wing, and the sections of the wings and the horizontal tail wing form an arch shape by bending the plastic strips; the front plug is provided with a rotating shaft, the propeller is arranged at the front end of the rotating shaft, the inner end of the rotating shaft is fixedly connected with a front hook, the rear plug is fixedly connected with a rear hook, and the rubber band is arranged on the front hook and the rear hook; the lower part of the wing is provided with a front landing gear, the lower part of the tail end of the body is provided with a rear landing gear, and the top surface of the body is provided with a vertical tail wing.
The inclined long thin slits are two parallel up and down.
The invention has the following positive effects: because the wings and the horizontal tail wings are directly inserted into the long and short slits on the machine body, the manufacturing is easy, the children of low age can conveniently and automatically manufacture the wing, the manufacturing interest is improved, and the intelligence of the children is developed; the plastic strips below the wings and the horizontal tail wing can be bent into an arch shape, so that the wings and the horizontal tail wing have rigidity on one hand, and the wings and the horizontal tail wing have arch-shaped sections on the other hand, wherein the arch-shaped sections of the wings form a streamline shape above the wings, so that the wind speed above the wings is improved, and the concave shapes are formed below the wings, so that the wings can catch wind, the wind speed below the wings is reduced, and the lift force is greatly improved; the angle of inclination of the arched section of the horizontal tail can be adjusted through different bending forms of the plastic strip, so that the stability of the airplane is improved. The effect of the plastic strip is particularly emphasized, the plastic strip can be bent at will, so that the bent flying effect is different, the optimal flying effect is found through different bending forms, and various flying principles are included, so that the interest of children in model airplanes is stimulated, and the understanding of the children on the flying theory is greatly improved.
