Zusammenfassung:
Preliminary wind tunnel tests of the full-size Model 412/IBC rotor at the Ames Research Center, NASA, are described. Blade lag motion was excited by swash plate oscillation, and the lag response was measured using blade-mounted accelerometers and compared with measurements using a conventional angle transducer. The recorded open-loop accelerometer signals were used as input to the Jag-BC system in the laboratory. The resulting controller cyclic pitch outputs are compared with the original cyclic pitch excitation inputs, and the potential effectiveness of the controller in suppressing the original excitation is evaluated. Recent developments in !BC technology and related rotor state measurements are briefly described in an appendix.
