Allison, Application of Two Procedures for Dual-Point Design of Transonic Airfoils, NASA TP, Septemberpp. to have advanced design such as shock-free transonic blades and blades with optimized dihedral. Many design methods were proposed in both research stage and industrial appli-cations [19].

The blade design methods can be categorized into two basic meth-ods. One is direct design and another is inverse design method.

For direct design. () Transonic buffet instability: From two-dimensional airfoils to three-dimensional swept wings. Physical Review Fluids () Elastodiffusion and cluster mobilities using kinetic Monte Carlo simulations: Fast first-passage algorithms for reversible diffusion processes.

We propose two methods to construct artificial farfield boundary conditions for the numerical treatment of twodimensional compressible, viscous flows around airfoils.

Domain decomposition methods (with and without overlapping of the subdomains) couple different models of conservation laws. Recent applications of CFD to solve the Navier Stokes equations for wind-turbine airfoils are reflected in the works of Chang et al.

They used their in-house code to solve the 2D flow field around the S and S airfoils with attached flow and the S airfoil with separated flow. Notable examples of the power of this method include the achievement of the Wright brothers in leaving the ground (after first building a wind tunnel), and more recently Whitcomb's discovery of the area rule for transonic flow, followed by his development of aftloaded supercritical airfoils and winglets (Whitcomb, ).

A canard is an aeronautical arrangement wherein a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft or a weapon. The term "canard" may be used to describe the aircraft itself, the wing configuration, or the foreplane.

Canard wings are also extensively used in guided missiles and smart bombs. The term "canard" arose from the appearance of the Santos-Dumont.

NASA airfoils; NASA has developed airfoil shapes for special applications. For example GA(W) series airfoils were designed for general aviation aircraft.

The LS series of airfoils among these are for low speed (LS) airplanes. A typical airfoil of this category is designated as LS(1) Dual use applications include: machine vision, autonomous vehicles, security, process control, environmental monitoring, scientific instruments, and astronomy.

These are called two-dimensional as they model an infinite wing and effects such as crossflow or tip vortices are thereby neglected.
