This report presents the implementation of a numerical method of low computational effort based on Blade Element Momentum Theory combined with a Vortex Lattice Method using a simple slipstream model to determine basic effects and trends of such aerodynamic interaction effects for conducting design studies regarding principle parameters of propeller-wing tractor configurations.Abstract:
The scalability and lightweight design of electric motors within (hybrid-) electric propulsion systems facilitates the distribution of propulsion. The aerodynamic interaction of a swirling propeller slipstream and a lifting surface can be beneficial regarding a vehicle’s propulsive efficiency. This report presents the implementation of a numerical method of low computational effort based on Blade Element Momentum Theory combined with a Vortex Lattice Method using a simple slipstream model. Goal of the method is to determine basic effects and trends of such aerodynamic interaction effects for conducting design studies regarding principle parameters of propeller-wing tractor configurations. The implementation is depicted and a verification is given with experimental results from literature.read more

Design of optimum propellers
TL;DR: In this paper, an iterative scheme is introduced for accurate calculation of the vortex displacement velocity and the flow angle distribution, and the exactness of this agreement makes possible an empirical verification of the Betz condition that a constant displacement velocity across the wake provides a design of maximum propeller efficiency.
Aerodynamics of v/stol flight
TL;DR: In this article, a set of notes collected over the years in connection with a helicopter aerodynamics course, integrates the field of V/STOL aerodynamics into a discourse on helicopters.
