<hr />
<div>In Barrowman’s ever popular report on rockets and center of pressure (TIR-33), page 11 on fin interference the formula including deltaXf indicates only the fin’s root and tip influence the center of pressure. Fin span is not included. In Open Rocket changing span changes the center of pressure, which makes sense. What am I missing?</div>2601:1C1:8581:B800:B82D:FAA:BE27:3C38
