An aero-structural algorithm to reduce the energy consumption of a propeller-driven aircraft is developed through a propeller design method coupled with a Particle Swarm Optimization (PSO). A wide range of propeller parameters is considered in the optimization. including the geometry of the airfoil at each propeller section. The propeller performance prediction tool employs a converge... http://www.bekindtopets.com/best-buy-Selle-CHROMAG-OVERTURE-Rails-CrMo-Violet-amazing-save/
