This book was released on 2018-07-08 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the development of lateral-directional flying qualities guidelines with application to eigenspace (eigenstructure) assignment methods. These guidelines will assist designers in choosing eigenvectors to achieve desired closed-loop flying qualities or performing trade-offs between flying qualities and other important design requirements, such as achieving realizable gain magnitudes or desired system robustness. This has been accomplished by developing relationships between the system's eigenvectors and the roll rate and sideslip transfer functions. Using these relationships, along with constraints imposed by system dynamics, key eigenvector elements are identified and guidelines for choosing values of these elements to yield desirable flying qualities have been developed. Two guidelines are developed - one for low roll-to-sideslip ratio and one for moderate-to-high roll-to-sideslip ratio. These flying qualities guidelines are based upon the Military Standard lateral-directional coupling criteria for high performance aircraft - the roll rate oscillation criteria and the sideslip excursion criteria. Example guidelines are generated for a moderate-to-large, an intermediate, and low value of roll-to-sideslip ratio. Davidson, John B. and Andrisani, Dominick, II Langley Research Center...

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.

This book was released on 2002 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A piloted simulation study conducted in NASA Langley Visual Motion Simulator addressed the impact of dynamic aero- servoelastic effects on flying qualities of a High Speed Civil Transport. The intent was to determine effectiveness of measures to reduce the impact of aircraft flexibility on piloting tasks. Potential solutions examined were increasing frequency of elastic modes through structural stiffening, increasing damping of elastic modes through active control, elimination of control effector excitation of the lowest frequency elastic modes, and elimination of visual cues associated with elastic modes. Six test pilots evaluated and performed simulated maneuver tasks, encountering incidents wherein cockpit vibrations due to elastic modes fed back into the control stick through involuntary vibrations of the pilots upper body and arm.

Book Synopsis Aircraft Maneuvers for the Evaluation of Flying Qualities and Agility by : David J. Wilson
Download or read book Aircraft Maneuvers for the Evaluation of Flying Qualities and Agility written by David J. Wilson and published by . This book was released on 1993 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A set of aircraft maneuvers has been developed to augment evaluation maneuvers used currently by the flying qualities and flight test communities. These maneuvers extend evaluation to full aircraft dynamics throughout the aircraft flight envelope. As a result, a tie has been established between operational use and design parameters without losing control of the aircraft evaluation process. Twenty maneuvers are described as an initial set to examine primarily high-angle-of attack conditions. Perhaps as important as the maneuvers themselves is the method used to select them. These maneuvers will allow direct measurement of flying qualities throughout the flight envelope instead of merely comparing parameters to specification values.
