| dc.description.abstract | An automated procedure for tiltrotor performance sensitivity calculation based on a V/STOL aircraft performance and sizing code, VASCOMP, is presented. The technique utilizes internal UNIX utilities and shell scripts, and will provide the option of changing the analysis code. Hence, VASCOMP is a testbed for future application of this approach on different analysis codes in an aeroservoelastic wing optimization process. Sensitivities are analyzed for different configurations deviating in single design variables from a EUROFAR-type baseline. A speed parameter and wing thickness to chord ratio are identified as major design drivers. It is concluded that, if only VASCOMP was to be used for optimization of the productivity index, PI, the resulting configuration would be prone to aeroelastic instability. Thus, inclusion of wing static load and aeroelastic stability constraints using more sophisticated tools is strongly recommended. | en_US |
