UQ Analysis and Robust Optimization of a Transonic Airfoil for Open Rotor Design

9th European Congress on Computational Methods in Applied Sciences and Engineering
Cet article présente une comparaison de techniques efficaces de quantification d'incertitude et d'optimisation robuste. Deux cas test basés sur un profil mince représentatif d'une pale de soufflante non carénée sont étudiés dans des conditions transsoniques.

Design of Airfoil for downwind wind turbine Rotor

, 2009
This thesis is on the design of an airfoil for a downwind wind turbine rotor with thin flexible wings, for offshore floating conditions. It has been suggested that such a system would to be lighter, simpler and allow for the use of more efficient airfoils. There has been a significant amount of work done at NTNU to develop a high-lift airfoil.

Study of the aerodynamic structure around a NACA6409 airfoil rotor

International Journal of Energetica
The multi-copters are one of the important aircrafts in the world because they are used in both military and civil application. The problem of these aircrafts is the low efficiency of its propellers. That’s why, it is necessary to study the aerodynamic structure around every rotor.
