Paraboloid net

A paraboloid refers to a group of solids formed by rotating a flat geometric figure around an axis, in the case of a paraboloid, the rotation of the curve formed by the parabola function.

How can you make a paraboloid of paper?

We suggest building a paraboloid model, with the following characteristics: height 130 mm, base diameter 85 mm. Download a paraboloid net.

Paraboloid assembly scheme:
1. Glue the upper part of the pattern.
2. Connect the formed domed part.
3. To avoid difficulties and shift when gluing the base, we recommend that you first glue the auxiliary elements. This will allow you to hold them smoothly when gluing and create the geometric design correct shape.
4. Glue the base.
An example from architecture.
building paraboloid

We could not find the buildings that exactly repeated the parabola formula, but there is a skyscraper in London (United Kingdom) with a very unusual shape. The Mary Eks skyscraper referred to by locals as the Cucumber (or the Gherkin), has no corners, which prevents the wind flow from flowing down and provides natural ventilation. The height of the 41-story building is 180 meters. The building's diameter at the base is 49 meters, which then expands smoothly, reaching a maximum diameter of 57 meters at the level of the 17th floor. The design then narrows, reaching a minimum diameter of 25 meters.
