This paper presents experimental and theoretical studies on the dynamic effect on the propeller loading due to ventilation by using a simulation model that generates a time domain solution for propeller forces in varying operational conditions. For ventilation modeling. the simulation model applies a formula based on the idea that the change in lift coefficient due to ventilation comp... https://www.roneverhart.com/Lucky-Shamrock-4-leaf-Clover-Buckle-With-FREE-Leather-Belt/
