Two elliptic cone configurations are being tested. The first has 2:1 cross section with a half-angle along the major axis of 13.8 degrees. It is the first 0.1524 m section of the 1.016 m cone which ...

The major axis of the elliptic cone is the same length as the radius of the circle. The cones have a common vertex at the center. This was the simplest of five models Wheeler designed of “cones with a ...
