ef 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...
متن کاملEvaluation 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 کاملHelicopter Rotor Airloads Prediction Using CFD and Flight Test Measurement in Hover Flight
An implicit unsteady upwind solver including a mesh motion approach was applied to simulate a helicopter including body, main rotor and tail rotor in hover flight. The discretization was based on a second order finite volume approach with fluxes given by the Roeand#39;s scheme. Discretization of Geometric Conservation Laws (GCL) was devised in such a way that the three-dimensional flows on arbi...
متن کاملCode-to-Code Comparison of CFD/CSD Simulation for a Helicopter Rotor in Forward Flight
Two unsteady Reynolds-averaged Navier-Stokes solvers are used to compute the rotor airloads on the UH-60A rotorcraft at several flight conditions across the flight envelope. One code, OVERFLOW, solves the flow equations using either structured grids, or a combination of structured and Cartesian grids. The other solver, FUN3D, uses unstructured grids. Both flow solvers are coupled to the same ro...
متن کاملSurrogate Based Optimization of Helicopter Rotor Blades for Vibration Reduction in Forward Flight
The effectiveness of surrogate modeling of helicopter vibrations, and the use of the surrogates for optimization of helicopter vibration are studied. The accuracies of kriging, radial basis function interpolation, and polynomial regression surrogates are compared. In addition, the surrogates for the vibratory hub shears and moments are used to generate an objective function which is employed in...
