Computational-Fluid-Dynamics- and Computational-Structural-Dynamics-Based Time-Accurate Aeroelasticity of Helicopter Rotor Blades
نویسنده
چکیده
A modular capability to compute dynamic aeroelastic characteristics of rotor blades using the Euler/Navier– Stokes flow equations and finite element structural equations is presented. The approach is based on a time-accurate analysis procedure that is suitable for nonlinear fluid–structure interaction problems. Fluids and structural solvers are time-accurately coupled in the C++ environment. Unsteady aerodynamic and aeroelastic results are validated with experimental data for nonrotating and rotating isolated blades.

متن کاملA Dynamics Model of Rotor Blades for Real-time Helicopter Simulation
We present a dynamics model of rotor blades for real-time helicopter simulation. Collisions between the air flow and the moving blades make helicopters fly. In aerodynamics, or even in computer simulations, they precisely analyzed the collisions between the fluid(air) and the solid object(blades), and calculated the differential equations from the collisions. Thus, it was hard for them to gener...
