Leishman provides the mathematical framework to calculate these limits and design rotors that push past them. 5. Unsteady Aerodynamics
By analyzing the lift and drag at various points along the span of a rotating blade, engineers can account for blade twist, taper, and airfoil shape. engineers can account for blade twist
The book explains how to calculate the power required to hover and introduces the Figure of Merit , a standard efficiency metric for rotors. a standard efficiency metric for rotors.
