Abstract : This volume contains transient time-history data extracted from the CH-46E SLEP II flight test program conducted at the Boeing Vertol flight test facility from 20 June to 31 October 1977. Four general types of data record are presented: Dynamic stability (longitudinal pulse response); Control responses (longitudinal, lateral and directional step response); SAS failure (longitudinal, lateral and directional hardover SAS input); and Engine failure (single engine step reduction to ground idle). In each record, the response of the helicopter in the axis of disturbance (control input, SAS failure, etc.) is thoroughly described by time-histories of six to eight relevant parameters in that axis, while interaxis coupling is assessed by a sampling of four parameters from each of the remaining axes.
