Aircraft Head Shape

This exhibit is an experimental booth demonstrating the relationship between fluid resistance and object shape. Four contrasting objects are set up in the booth, namely a cone, a cylinder, and two streamline bodies with the same shape but opposite placement directions. Place the comparison objects in a stationary sink and use the same hook code to maintain the same tension on the comparison objects. Release the hook code, and the object will start moving from the starting point. By comparing the speed of the object's movement, the difference in resistance experienced by objects of different shapes in the fluid can be compared.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

When an object moves in air or water, it is obstructed by a force from the fluid, which is called fluid resistance. The magnitude of fluid resistance is influenced by various factors, among which the shape of the object plays an important role. The streamlined shape allows air or water flow to bypass objects more smoothly, reducing turbulence and thus lowering resistance. Therefore, the nose of an aircraft is often designed to be streamlined, which can reduce air resistance and make the aircraft fly faster and more energy-efficient.
