In the advent of electrical vertical take-off and landing aircraft development, a fast approach to predict variation of propeller axial and off-axis aerodynamic loads at large incidence angle has been desired. This paper presented an analytical approach obtained by a simplified blade element method considering local blade section conditions. The theory has been further validated against available experiments for propeller at high incidence conditions, and was found applicable to a wide range of geometries and operating conditions.
