Sinner Mango Velomobile wheel arch aerodynamic improvements

thingiverse

Sinner's Mango velomobile is aerodynamic and fast, but like most things it can be improved upon. I've experimented with strips in front of the wheel arches in the past, using glued on cotton to observe the airflow, and these help to disrupt laminar flow and ensure that the airflow does not stick to the body and divert into the wheel arch, creating drag, but that it goes past the wheel arch in a straight line. These printed parts should always ensure that this occurs because the soft rounded corner of the mold from which the body is taken has been replaced by a sharp corner with a point to which the airflow cannot "stick". See the photos. These parts should be fitted to the Mango body with bathroom sealant. Read more about my Sinner Mango velomobile. Watch video of the two parts being made. We sell parts for all types of bicycles including velomobiles.
