Embodiment Construction

[0016] In this embodiment, the aircraft model 6 is placed in the air through the suspension device, and the flow field around the aircraft is simulated through a small wind tunnel. Under the action of this flow field, the aircraft can generate lift; by controlling each rudder surface of the aircraft, the aircraft model can realize various flight attitudes.

[0017] This embodiment includes a demonstration aircraft model 6, a casing 1, and a hanging device. The specific implementation process is:

[0018] Demonstration aircraft model 6 adopts a remote-controlled wooden model. The fuselage of the aircraft is a cavity structure, and the control system and receiving system are all installed in the fuselage. There is a circular hole on the back of the center of gravity of the aircraft, and a joint bearing is housed in the circular hole. Airplane model is suspended in demonstration box 7 by hanging device.

[0019] The box body is made of hard iron sheet and is divided into two l...

Abstract

The present invention is one comprehensive demonstrator for flying principle of airplane. The demonstrator has casing to form one small wind tunnel capable of simulating the flow field around airplane; airplane model with knuckle bearing in the gravitational center on the back and hung with hanging unit inside the demonstrating casing; and hanging unit in balancing lever structure with hanging rod and balancing rod separately on two ends of the balancing rod, supporting rod in the middle part of the balancing rod, movable connections to the balancing rod to ensure the free rotation of the balancing rod and the hanging rod inside vertical plane to realize various flying postures. The present invention can simulate various flying postures of airplane, including yaw, roll and pitching and demonstrate flying principle intuitively.

Description

(1) Technical field: [0001] The invention relates to an instrument for demonstrating the principle of aircraft flight, which is a comprehensive demonstration instrument for the principle of aircraft flight used in the teaching of aviation science popularization. (two) background technology: [0002] The technology related to this invention is smoke wind tunnel. [0003] The smoke tunnel is often used as an aerodynamic teaching tool. It can simulate the airflow characteristics of the aircraft when it moves in the air to the public. The smoke released can clearly demonstrate the direction and change of the airflow through the model. The models in the wind tunnel are generally static, and cannot simulate the various flight attitudes of the aircraft model under the action of the airflow, such as yaw, roll and pitch. The limitation of Yanfeng Tunnel is that its functions are relatively single, and it can only realize the airflow characteristics formed by a single movement of a c...
