Volute > Cross Section > Radius based cross section

The shape of a radius based cross section is described by straight lines and circular arcs.

The geometry is described by the following parameters:

base height	h	height of the radial base part
base radius	RB	rounding between base part and cone part (radius can be limited due to length of base part and cone part)
opening angle	δ	angle of the cone part
corner radius	RC	rounding between cone part and main circular arc on top (radius can be limited due to length of cone part and circular arc on top)
main radius	R	radius of main circular arc on top
