Improved Blade Element Theory and Autorotating Rotor Aerodynamic Characteristics Analysis
نویسندگان
چکیده
During forward flight, the flow field of autorotating rotor was very complicated, which caused induced velocity disc plane difficult to be obtained. In order analyze aerodynamic characteristics rotor, improved blade element theory, using unlimited-bladed fixed wake method establish a mathematical model, could obtain by rotor. According Biot-Savert Theorem, expression axial got integerating. The circulation and were all expanded into Fourier series azimuth, then carried out iteration. Combined forces obtained, analyzed its characteristics.

Evaluation of Rotor Structural and Aerodynamic Loads Using Measured Blade Properties
The structural properties of Higher harmonic Aeroacoustic Rotor Test (HART I) blades have been measured using the original set of blades tested in the wind tunnel in 1994. A comprehensive rotor dynamics analysis is performed to address the effect of the measured blade properties on airloads, blade motions, and structural loads of the rotor. The measurements include bending and torsion stiffness...
متن کاملA moderate deflection composite helicopter rotor blade model with an improved cross-sectional analysis
The compatibility between a composite beam cross-sectional analysis based on the variational asymptotic approach, and a helicopter rotor blade model which is part of a comprehensive rotorcraft analysis code is examined. It was found that the finite element cross-sectional analysis code VABS can be combined with a moderate deflection rotor blade model in spite of the differences between the form...
متن کاملWind turbine blade shear web disbond detection using rotor blade operational sensing and data analysis.
A wind turbine blade's structural dynamic response is simulated and analysed with the goal of characterizing the presence and severity of a shear web disbond. Computer models of a 5 MW offshore utility-scale wind turbine were created to develop effective algorithms for detecting such damage. Through data analysis and with the use of blade measurements, a shear web disbond was quantified accordi...
متن کاملoptimization of composite rotor blade using merged genetic algorithm and finite element method
in this paper, an optimization method for both weight and displacement of composite blades is presented. in order to hold issues such as aerodynamics and acoustic unchanged, airfoil shape during optimization process remained constant. to achieve the ultimate goal, only blade lamination was changed. in order to achieve minimum weight for each part of the structure, the lowest layers are foreca...
متن کاملef the Aerodynamic Interference a Helicopter Rotor Blade and a and Wing in Hovering and Fer - ward Flight
The Report presents a theory of the aerodynamic interference between a helicopter rotor blade and a fuselage or wing. A two-dimensional analysis is made to which a correction factor is applied to convert the two-dimensional calculations to the appropriate three-dimensional case. The pressures and forces on circular and square-sectioned fuselages and on wings are calculated for hovering flight a...
