This book was released on 1978 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical study was conducted to evaluate the relative improvements in aircraft ride qualities that resulted from utilizing several control law configurations that were optimized for pilot handling qualities only. The airplane configuration used was an executive jet transport in the approach configuration. The control law configurations included the basic system, a rate feedback system, three command augmentation systems (rate command, attitude command, and rate command/attitude hold), and a control wheel steering system. Both the longitudinal and lateral directional axes were evaluated. A representative example of each control law configuration was optimized for pilot handling qualities on a fixed base simulator. The root mean square airplane responses to turbulence were calculated, and predictions of ride quality ratings were computed by using three models available in the literature.

Available in PDF, EPUB and Kindle. Book excerpt: This report is a codification in two parts of conventional aircraft handling qualities criteria. The results of this effort are to serve as an intermediate design guide in the areas of lateral-directional oscillatory and roll control. The roll handling qualities portion of this report uses as a point of departure the concept that control of bank angle is the primary piloting task in maintaining or changing heading. In the lateral oscillatory portion of this effort, in defining requirements for satisfactory Dutch roll characteristics, a fundamental consideration is the fact that the motions characterizing this mode are ordinarily not the pilot's chief objective. That is, he is not deliberately inducing Dutch roll motions in the sense that he induces rolling and longitudinal short-period motions. A worthwhile approach to establishment of Dutch roll damping requirements is to first establish the basic level, and then to study the varied influences of the disturbance parameters. This approach provides the basis for the material contained in this report.

Download or read book A Flight Investigation of Lateral-directional Handling Qualities for V/STOL Aircraft in Low Speed Maneuvering Flight written by Karl-Heinz Doetsch and published by . This book was released on 1970 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation to determine the ranges of various lateral directional characteristics required to provide adequate flying qualities for turning maneuvers at low speed was undertaken using an airborne V/STOL aircraft simulator. Five parameters were varied in a systematic manner: the damping ratio, the frequency, and the ratio and the frequency of the numerator of the roll-angle to aileron-control-input transfer function. The pilots performed a low speed, visual maneuvering task and documented their assessment of the characteristics through extensive comments and a numerical rating. The report presents all the data categorized with respect to the test parameters. (Author).

This book was released on 1965 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a flight research program to evaluate the effects of certain lateral-directional handling qualities are reported and discussed. The evaluation program was designed to assess the acceptability of variations in Dutch roll dynamics and aileron-yaw coupling for the low speed landing approach task. The effects of a reduction in static directional stability on the high Mach number cruise task were also evaluated. A variable stability T-33 was used for conducting these evaluations. Thirty-three different sets of low speed, and fifteen different sets of high speed lateral-directional handling qualities were evaluated by an experimental test pilot. The evaluation pilot comments and a numerical rating were given for each configuration as to its suitability for the mission or task involved. Identification of the stability parameters from in-flight records was made using airplane rudder doublet responses and the Equations-of-motion Technique. An analysis was made of the pilot ratings and pilot comments, and these in turn were correlated with the lateral-directional stability parameters measured. (Author).

This book was released on 1988 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines the relationship between an aircraft's lateral-directional handling qualities and its corresponding eigenstructure. Intuition and simple methematical models were used to develop desirable eigenvectors. For conventional aircraft, the dutch roll eigenvector was shown to a function of the roll to sideslip (phi/beta) ratio. Flight control laws to produce the desired eigenstructures were derived using eigenstructure assignment with output feedback. The control laws were based on a twelfth order linear model of the lateral-directional dynamics of the YA-7D DIGITAC, and varied the dutch roll phi/beta ratio. The handling qualities of the YA-7D were examined. The flight testing consisted of both open loop tasks, and closed loop tasks in which Cooper-Harper ratings were assigned.

Available in PDF, EPUB and Kindle. Book excerpt: The report uses as a point of departure the concept that control of bank angle is the primary piloting task in maintaining or changing heading. Regulation of the bank angle to maintain heading is a close-loop tracking task in which the pilot applies aileron control as a function of observed bank angle error. For large heading changes, the steady-state bank angle consistent with available or desired load factor is attained in an open-loop fashion; it is then regulated in a closed-loop fashion throughout the remainder of the turn. For the transient entry and exit from the turn, the pilot is not concerned with bank angle per se, but rather with attaining a mentally commanded bank angle with tolerable accuracy in a reasonable time, and with an easily learned and comfortable program of aileron movements.

This book was released on 2018-07-24 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of analysis of cockpit lateral control feel-system studies. Variations in feel-system natural frequency, damping, and command sensing reference (force and position) were investigated, in combination with variations in the aircraft response characteristics. The primary data for the report were obtained from a flight investigation conducted with a variable-stability airplane, with additional information taken from other flight experiments and ground-based simulations for both airplanes and helicopters . The study consisted of analysis of handling qualities ratings and extraction of open-loop, pilot-vehicle describing functions from sum-of-sines tracking data, including, for a limited subset of these data, the development of pilot models. The study confirms the findings of other investigators that the effects on pilot opinion of cockpit feel-system dynamics are not equivalent to a comparable level of added time delay, and until a more comprehensive set of criteria are developed, it is recommended that feel-system dynamics be considered a delay-inducing element in the aircraft response. The best correlation with time-delay requirements was found when the feel-system dynamics were included in the delay measurements, regardless of the command reference. This is a radical departure from past approaches. Mitchell, David G. and Aponso, Bimal L. and Klyde, David H.
