Propeller Blockage factors
Propeller Blockage factors
(OP)
HI
I am looking for a method for calculating the thrust loss due to propeller body interactions (due to the increase in local velocity & pressure effects).
I currently am using the S.B.A.C. Standard Method of Propeller Performance Estimation, but would like to find a second method to estimate the loss. The methods in Torenbeek & Roskam originate from the SBAC method.

When I said Roskam, I should have said Lan & Roskan meaning "Airplane Aerodynamics and Performance" rather than “Airplane Design” which strangely is missing any mention of it.
