Arrow and Vane Drag

A University of Colorado Study

To develop a scientific understanding of what characteristics produce a higher performing vane on fixed blade broadheads, we sponsored a University of Colorado Boulder study. This report shares a portion of the study's findings with regards to arrow drag, which they've found to be one of the principal aspects of arrow and vane performance. 

KEY FINDINGS

MINIMIZE DRAG TO IMPROVE ARROW FLIGHT

Drag from the broadhead, arrow shaft, and vanes slows down arrow speeds, which will increase arrow drop at longer ranges. This study quantifies which features contribute to higher drag.

2-3° FLETCHED VANES PERFORM BEST OVERALL

While a shallower angle will incur the smallest drag, a 2-3 degree angle will perform best overall.

"This study takes a closer look at various types of drag impacting arrows so bow hunters can build the best performing arrows, which minimize drag and wind drift."
