Teaching-purpose Balsa wood airplane

Abstract

The invention discloses a teaching-purpose Balsa wood airplane. The airplane herein includes wings, a fuselage, an empennage and a power structure. The wings are fixed to the fuselage through a wing fixing structure. The wings are in vertical connection to the wing fixing structures. The dihedral angle of each wing is regulated through a vertical triangle angle in the wing fixing structure. The angle of attack of each wing is regulated through the tilting of a transverse triangle in the wing fixing structure. The wings can move back and forth in the fuselage. The empennage is connected to a tail part of the fuselage. The power structure includes a propeller, a front hook, a tail hook and a rubber band. The propeller is disposed at the front end of the fuselage. The tail hook is fixed to the tail part of the fuselage. The rubber band wraps the tail hook and one end of the front hook. The other end of the front hook penetrates the fuselage and is then connected to the propeller. According to the invention, the airplane herein has the following advantages: the airplane can visualize the regulation of dihedral angle, angle of attack, center of gravity and energy, achieves the effects of teaching through exploration and practice, has the advantages of exquisite structure design, easy assembling, disassembling and regulation, and can explain important airplane-related knowledge points in a direct manner by using a simple structure.

Description

technical field [0001] The invention relates to a balsa wood aircraft for teaching, which belongs to the technical field of aircraft model teaching aids. Background technique [0002] There are few kinds of teaching aids for traditional model airplane teaching, and people of different ages are often playing with the same model airplanes, which is not targeted. The knowledge learning of airplane models can be learned from simple to deep, from easy to difficult. Before the product market is subdivided, Many things are unprofessional and lack professional and targeted product design. In addition, the finished model airplanes sold on the market only reflect the assembly process and lack the creativity of teaching. Students just play with toys. The reason for this problem It is useless to design aircraft model teaching aids from the perspective of professional education and teaching. Contents of the invention [0003] The technical problem to be solved by the present invention...
