Mathematics has been kept to a minimum, but it is assumed that the reader has a knowledge of differential and integral calculus, and elementary mechanics.

The theoretical treatment progresses from elementary considerations to methods used for the design of NACA low-drag airfoils. In this paper, the results of primitive optimization for determining the fundamental characteristics of motion and the trajectory of the wind turbine blade are demonstrated in order to obtain smooth rotation of the generator-driving shaft.

It is also shown that the present turbine can be driven at low speed with a suitable energy conversion rate.

The appendix of over pages contains these tables: Including a Summary of Airfoil Data By: Smart Grid and Renewable EnergyVol. Product Description Product Details “Most useful in working with wing sections and methods for using section data to predict wing characteristics.

Theory of Wing Sections: Including a Summary of Airfoil Data

The chapters on theory of thin wings and airfoils are particularly valuable, as is the complete summary of the NACA’s experimental observations and system of constructing families of airfoils. Assuming one-blade motion with a variable trajectory for optimization, the smooth motion and required torque at doenhofff rotation speeds are studied.

User Review – Flag as inappropriate very good. Intended to be primarily a reference work for engineers and students, the book devotes over pages to theoretical and experimental considerations. The concept involves the unique flapping motion of a wind blade mounted on a Chebyshev-dyad linkage by which the wing transforms wind energy abobtt mechanical rotation. Intended to be primarily a reference work for engineers and students, the book devotes anc pages to theoretical and experimental considerations.
