“…Their experience ranged from business jets and large transports to military bombers including the B-1B. Prior to data collection, the research team modified the Hyperlinked-Overview of Piloted Evaluations (HOPE) 7 database for storing and searching data for piloted studies so that the data and comments collected during the study would be well-documented and easily accessed and sorted. The handling qualities were rated by each pilot based on the Cooper-Harper Rating Scale, as well as a DASE influence on Ride Quality Rating (RQR) scale and a DASE influence on pilot's control input -Control Influence Rating (CIR) scale.…”

The NASA Langley Research Center Cockpit Motion Facility (CMF) was used to conduct a piloted simulation assessment of the impact of flexible structures on flying qualities. The CMF was used because of its relatively high bandwidth, six degree-of-freedom motion capability. Previous studies assessed and attempted to mitigate the effects of multiple dynamic aeroservoelastic modes (DASE). Those results indicated problems existed, but the specific cause and effect was difficult to ascertain. The goal of this study was to identify specific DASE frequencies, damping ratios, and gains that cause degradation in handling qualities. A generic aircraft simulation was developed and designed to have Cooper-Harper Level 1 handling qualities when flown without DASE models. A test matrix of thirty-six DASE modes was implemented. The modes had frequencies ranging from 1 to 3.5 Hz and were applied to each axis independently. Each mode consisted of a single axis, frequency, damping, and gain, and was evaluated individually by six subject pilots with test pilot backgrounds. Analysis completed to date suggests that a number of the DASE models evaluated degrade the handling qualities of this class of aircraft to an uncontrollable condition. Further conclusions will be provided when analysis is complete.
