Rotorcraft System Identification (Identification des Systemes de Voilures Tournantes)
Abstract
For fixed wing aircraft, system identification methods to determine stability and control derivatives from flight test data are used with confidence. The application of the same techniques to rotorcraft is not so far advanced mainly because of the helicopter aeromechanical complexity. Only a few specialists, mostly in research organizations, have concentrated on this field and the application in industry is still sporadic. The Lecture Series is intended to establish an improved dialogue between government organizations, research institutions, and industry in order to apply these tools more routinely in rotorcraft design, development, and evaluation. The Lecture Series is supported by an unique flight test data set which was generated and analysed within a recent Working Group in the Flight Mechanics Panel of AGARD(WG18). It is based on the findings of the Working Group including a documentation of the data bases, the applied identification methodologies, the major application areas. Flight test obtained from three different helicopters (AH-64, BO 105, and PUMA) were evaluated. For each of the three helicopters, comparisons of the obtained results are discussed, covering data quality evaluations, identification, and the verification of the obtained models.
