Coupled Flap-Lag-Torsional Vibration Analysis of Pre-twisted Non-uniform Helicopter Blades
An approximate numerical mthod is presented for analysis and determination of modal characteristics in straight, pretwisted non-unifom helicopter blades. The analysis considers the coupled flapwise bending (out of plane), chordwise bending (in plane), and torsion vibration of both rotating and non-rotating blades. The proposed method is based on the integral expansion of Green functions (struct...

متن کاملMeasuring Angle of Attack of Helicopter Blades
Scientific and Technical Information Office 1980 SUMMARY Systematic investigations were performed on a variety of probes to determine their potential for possible application as sensors attached to helicopter blades to measure both the instantaneous angle of attack as well as the dynamic head during actual flight operations. After some preliminary considerations a sensor of essentially spherica...

متن کاملNonlinear Modeling and Control Design of Active Helicopter Blades
The paper presents the theoretical basis for the simulation of active helicopter blades. The analysis of active helicopter blades is based on models for the structure, aerodynamics, actuation and sensing. For simulation and analysis purposes, the blade structural model is discretized in space using a Galerkin approach. The effect of the integral actuation enters the beam model via an active bea...
