A REVIEW OF HELICOPTER AEROELASTIC STABIL ITY RESEARCH

The complex multi-disciplinary nature of helicopter stability predicti on makes it appropriate from time to time to take stock of how analysi s methods are developing. Current procedures for predicting helicopter stability are reviewed. Much of the discussion is framed within the w ider context of helicopter aeroelastic response analysis in general, a nd emphasis is placed as much as possible on practical aspects of the problem. Areas are identified in which future theoretical developments and experimental Validation are likely to be most beneficial.
