Survey of recent developments in rotorcraft design optimization

The helecopter optimization problem and the flexibility of the main rotor blades couples with the aerodynamics control system were discussed. The helecopter optimization involve, presense of numerical noise and finite element analysis. It was observed that by increasing power of the computers, the problem of expensive aeroelastic and finite element analysis could be solved. It was suggested that for the better modeling, the use of computational fluid dynamics (CFD) for aerodynamic predictions and full finite elements methods formulation for the composite rotor blade structural analysis was made. The development of sensitivity analysis and improved predictability of rotorcraft analysis make it possible for creating optimization solution.
