This Rotorcraft Aerodynamics For Vtol Engineers eBook from 3D-LABS is written for engineers and students who want a clear, practical reference they can apply immediately.
Rotorcraft Aerodynamics for VTOL Engineers covers blade element momentum theory, vortex wake models, ground effect, autorotation, and compound VTOL configurations for helicopter and VTOL rotor design.
What standards does this book reference?
FAR Part 27 (normal category rotorcraft), FAR Part 29 (transport rotorcraft), EASA CS-27/CS-29, and ADS-33E-PRF for rotorcraft handling qualities.
What is the rotor hover thrust equation?
Momentum theory: T = 2*rho*A*v_h^2, where rho is air density, A = pi*R^2 rotor disk area. Figure of Merit FM = T^(3/2)/(sqrt(2*rho*A)*P_ideal), typically 0.75-0.80 for well-designed rotors. Blade element method refines for pitch, twist, planform, and tip loss.
What eVTOL and UAM content is included?
Distributed electric propulsion (DEP) aerodynamic interaction effects, multi-rotor power loading W/P trade-offs, tilt-rotor transition aerodynamics, and DGCA BVLOS RPAS rules for Indian UAM.
