Abstract:

This report provides users instructions for two computer programs for aeroelastic stability analysis and for aeroelastic proprotor loads analysis. Each program is carefully described and explained, symbols and sign conventions are identified, and input and output data are presented. A sample program run for each analysis is then given. In addition, sample programs for some subroutines are provided. Notes and suggestions on program usage are presented. The methods contained in this report are intended to be used by designers to calculate with improved accuracy, the dynamic and aeroelastic response characteristics of rotor powered VSTOL aircraft. The essential new feature of these methods is that the coupled flap-pitch-lag blade deflections are taken into account. These calculations are essential if a high level of confidence is to be had in the results.
