Proposal for a propeller side-force facto
Year: 1943
Abstract: Knowledge of the side force on a propeller in yaw The fin effect - is useful in the design of tail surfaces, in the testing of powered. aircraft models, and I in formal. stability and control analyses. A side-force factor computed from the plan form and pitch distribution in shown to be a good index of the relative effectiveness, per blade, of a yawed propeller in developing side force. By the general use of side–force factors, existing charts of propeller side force may be simply extrapolated to" give Me side force on any specified propeller in any specified operating condition. The suggestion is made that propeller manufacturers and designers present the stale-force factor with the activity factor as a fundamental parameter for all blade designs and that reports of tests of powered models in wind tunnels include the side-force factor for the propeller used.
