Description From an authoritative expert whose work on modern helicopter rotor blade
analysis has spanned over three decades, comes the first consistent and rigorous …

This paper presents an asymptotical formulation for preliminary design of multi-cell
composite helicopter rotor blades with integral anisotropic active plies. It represents the first …

The advanced active twist rotor (AATR) blade incorporating single crystal macro fiber
composite (single crystal MFC) actuators is designed and the aeroelastic analysis is …

This paper discusses how torsional stiffness is related with twist actuation in an integrally
twist actuated rotor blade. It shows that increase in torsional stiffness does not necessarily …

COMPOSITE rotor blades are, in general, builtup structures made of different materials for
the skin and spar, normally of closed single-or multicelled cross-sections, and thin walled …

A gradient-based optimization scheme has been developed for obtaining the maximum
coupling in thin-walled composite beams subject to hygrothermal and frequency constraints …

An Active Twist Rotor (ATR) is developed for future implementation of the individual blade
control for vibration and noise reduction in helicopters. The rotor blade is integrally twisted …

One of the main challenges for the civil aviation industry is the reduction of its environmental
impact. Over the past years, improvements in performance efficiency have been achieved by …

This paper presents an asymptotical formulation for analyzing multi-cell composite
helicopter rotor blades with integral anisotropic active plies. It represents the first attempt in …

In this work, a mixed beam approach that combines both the stiffness and the flexibility
methods has been performed to analyze the coupled composite blades with closed, two-cell …
