DLR'S MULTIPLE SWASHPLATE CONTROL SYSTEM: OPERATION AND PRELIMINARY TESTING

摘要

This paper describes the first tests of DLR's patented, IBC-capable multiple swashplate control system. It briefly covers the preliminary activities and system modifications necessary to ensure successful testing, such as the ground vibration tests. The conducted hover tests and their respective results are discussed in detail, focusing particularly on Higher Harmonic Control and Individual Blade Control test scenarios. Numerous control modes were tested with and without blades, including 2-6/rev HHC, in-flight blade tracking, and different modes of tip path plane-splitting.
