Description

Technical Field

[0001] The present invention relates to an experimental device, and more particularly to an experimental test device for an air propeller ship model. Background Art

[0002] An air propeller, also known as a "propeller" or "screw propeller", refers to a device that generates thrust by the rotation of blades in the air. It consists of several blades and a central hub. When the propeller is driven by the output shaft of the engine to rotate, the inclined surface of the blade pushes the air backward, and thus the blade obtains a reaction force, that is, the thrust. For a ship using an air propeller as a propeller, in addition to being able to navigate on the water surface, it can also adapt to special environments such as swamps, mudflats, ice surfaces, and snow surfaces.

[0003] Air propeller ships can be applied to multiple fields such as disaster relief, rescue, field operations, and exploration, and can operate in environments where conventional vehicles and ships cannot travel, such as water surfaces, snow fields, ice surfaces, deserts, and swamps.
