The Archimedean Spiral Turbine is a project developed to demonstrate the conversion of wind kinetic energy into mechanical energy through a helical geometry inspired by the Archimedes screw. Its compact and elegant design makes it ideal for educational use, experimental setups, or decorative installations.
Technical Features
- Turbine type: vertical-axis helical spiral
- Main components:
- Central shaft (1)
- Support base (2)
- Mounting foot (3)
- Turbine body (4)
- Mirrored shaft (5)
- Steel ball bearings 5972K91 (6–7)
- Recommended materials: PLA or PETG for printed parts, steel for bearings
- Approximate dimensions: total height ≈ 190 mm, max diameter ≈ 130 mm
- Mounting: fixed on a flat surface using M4 screws; free rotation on dual bearings
How It Works
The helical spiral captures airflow from any direction, generating continuous rotation of the central shaft. The curved blade profile maximizes thrust even with moderate wind, making the turbine suitable for aerodynamic efficiency tests and physics demonstrations.
Generator Compatibility
The turbine can be connected to a small DC motor used as a generator, allowing the production of low‑voltage direct current. This makes it ideal for micro‑generation experiments, powering LEDs, or demonstrating energy conversion principles.
Applications
- Educational experiments on wind energy and fluid mechanics
- Decorative or artistic installations on balconies and terraces
- Prototyping for small‑scale energy generation
Printing Instructions
- Orientation: print the turbine vertically to preserve blade curvature
- Supports: recommended only for the base and mounting foot
- Layer height: 0.2 mm
- Infill: 20–30%
- Material: PLA or PETG
Assembly
- Insert the steel ball bearings (6–7) into the side supports.
- Install the central shaft (1) and mirrored shaft (5) in their housings.
- Fix the base (2) and foot (3) using M4 screws.
- Place the turbine (4) onto the shaft and check for smooth rotation.
- Optionally connect a small DC motor to generate electricity.
