Plastic arched wing rubber band propeller model airplane

Abstract

The invention provides a plastic type model airplane with arched aerofoils, a rubber band and a propeller. A fuselage is a cylindrical body. The two ends of the fuselage are provided with a front endcap and a rear end cap. The front ends of the two sides of the fuselage are provided with oblique long thin gaps, and the rear ends are provided with oblique short thin gaps. The aerofoils and a horizontal empennage are elastic sheet bodies and are inserted in the fuselage through the oblique long thin gaps and the oblique short thin gaps. Plastic strips are arranged on the lower sides of the aerofoils and the horizontal empennage. By bending the plastic strips, the sections of the aerofoils and the horizontal empennage form an arch shape. A rotating shaft is arranged on the front end cap. Thepropeller 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 end cap is fixedly connected with a rear hook. The rubber band is arranged on the front hook and the rear hook. Front undercarriages are arranged on the lower faces of the aerofoils, a rear undercarriage is arranged on the lower face of the tail end ofthe fuselage, and a perpendicular empennage is arranged on the top face of the fuselage. The airplane is easy to manufacture and can be conveniently manufactured by young children on their own, manufacturing interestingness is improved, and children intelligence is developed; the plastic strips can be bent into an arch shape, and the lifting force and stability of the airplane are improved.

Description

technical field [0001] The invention relates to a model airplane, in particular to a model airplane with a plastic arched wing rubber band propeller. Background technique [0002] The rubber band propeller model airplane drives the propeller through the rubber band, and then the propeller drives the plane to take off. The earliest rubber-band propeller model aircraft, its fuselage and wings are made of wooden materials, and the rubber band is set outside the fuselage, its lift and stability are not good, and it is not beautiful; later the fuselage was changed into a tubular shape, and the rubber band It can be installed inside the fuselage, and the wings and tail are set on the fuselage through brackets, and can be made into a streamlined shape. Although it is beautiful, the weight of the wings and tail affects the lift, and the production is troublesome, which is not convenient for young children to make by themselves . Contents of the invention [0003] The purpose of ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defect that the existing elastic propeller model aircraft lacks lift and is troublesome in appearance, and invents a plastic arched wing that can shape the section of the wing and empennage into a streamlined feature to improve lift and stability rubber band propeller model airplane
