Flight principle demonstrating instrument

Abstract

The invention discloses a flight principle demonstrating instrument, which comprises a bottom plate, side plates, an air blower, a top plate and an adjustable wing plate, wherein there are two side plates, the two side plates are arranged in a mode of being perpendicular to the bottom plate, parallel to each other and made of a transparent material; the air blower is arranged on the bottom plate,the top plate is movably connected with the top of the top of the air blower, the air blower, the side plates, the top plate and the bottom plate form a cubic region with one side being open, and an air outlet of the air blower faces towards the open side of the cubic region; the adjustable wing plate includes two guide plates, the two guide plates are movably connected with the inner sides of thetwo side plates respectively, the guide plates can slide on the side plates along the vertical direction, a front positioning rod, a rotating rod and a rear positioning rod are connected between thetwo guide plates, and the rotating rod is movably connected with an adjusting cam. The flight principle demonstrating instrument is further provided with an elastic ring made of a rubber film to coverthe front positioning rod, the adjusting cam and the rear positioning rod. The flight principle demonstrating instrument can visually display the flight principle of an aircraft, is simple in structure and can display influencing factors affecting the rise of the aircraft.

Description

technical field [0001] The invention belongs to the field of teaching appliances, in particular to a flight principle demonstrator. Background technique [0002] When teaching flight principles, it is often difficult for students to understand due to the lack of intuitive experimental phenomena. When using aircraft models for demonstration, it is difficult for students to observe because the aircraft model is dynamic during flight. At the same time, because the structure of the aircraft model is fixed, Through a single demonstration of the aircraft model, it is not easy for students to understand the factors that affect the ascent of the aircraft. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to address the deficiencies in the current technology, to provide a flight principle demonstrator, which can intuitively display the flight principle of the aircraft, has a simple structure, and can display the factors that affect...
