Available in PDF, EPUB and Kindle. Book excerpt: A physical description of the destabilizing mechanism responsible for certain pilot-induced lateral-directional instabilities is presented. In addition, the theoretical and experimental effort proporting to support the physical ARGUMENTS IS INCLUDED. The basis for this study was a pilot-induced instability known to exist for the X-15 research aircraft-pilot combination for certain conditions of flight. Accordingly, a major portion of the effort was concentrated upon the analysis of a specific known instability. Nevertheless, it is the opinion of the authors that the resultant conclusions are quite general. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: From the early machines to today's sophisticated aircraft, stability and control have always been crucial considerations. In this second edition, Abzug and Larrabee again forge through the history of aviation technologies to present an informal history of the personalities and the events, the art and the science of airplane stability and control. The book includes never-before-available impressions of those active in the field, from pre-Wright brothers airplane and glider builders through to contemporary aircraft designers. Arranged thematically, the book deals with early developments, research centers, the effects of power on stability and control, the discovery of inertial coupling, the challenge of stealth aerodynamics, a look toward the future, and much more. It is profusely illustrated with photographs and figures, and includes brief biographies of noted stability and control figures along with a core bibliography. Professionals, students, and aviation enthusiasts alike will appreciate this readable history of airplane stability and control.

Available in PDF, EPUB and Kindle. Book excerpt: A method is developed for the assessment of lateral-directional pilot induced oscillation (PIO) tendencies. The method is applicable regardless of the flight control system mechanization. The relations between linear and non-linear system effects on the probability or nature of PIO are discussed. In its simplest form, the method proposed for PIO assessment is very similar to methods currently in use. The principal difference is that quantitative methods are provided for the identification of specific frequencies at which appropriate stability criteria must be satisfied if PIO is not to be a possibility. Based upon analyses in this report, the single axis, bank angle PIO is believed to be the most commonly encountered lateral-directional PIO. The possibility for pitch only PIO in the longitudinal mode is discussed. The methods of this report are believed to apply to the study of longitudinal PIO. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Stability and Control of Airplanes and Helicopters deals with aircraft flying qualities that determine the stability and control of airplanes and helicopters. It includes problems based on real aircraft, selected to represent the gamut from simple to complicated, and from conventional utility designs to futuristic research types. Many of these problems involve comparison of theory and experiment to demonstrate their mutual relationship. Comprised of 25 chapters, this book begins with a discussion on the aerodynamics of the component parts related to the lift and moment characteristics of an airplane, including wings and associated accessories; bodies such as fuselages, nacelles, and tip tanks; and control surfaces. The reader is then introduced to some mathematical techniques for linear differential equations; steady flight at different speeds; and stick force and control-free stability. Subsequent chapters focus on flaps and high-lift devices; power and compressibility effects; and the manner in which the aircraft responds to the application of control. Aeroelasticity and longitudinal equations of motion are also examined. This monograph is intended for undergraduate and graduate students taking modern engineering courses.

Download or read book Analysis of a Coupled Roll spiral mode Pilot induced Oscillation Experienced with the M2 F2 Lifting Body written by Robert W. Kempel and published by . This book was released on 1971 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 16 glide flights of the M2 -F2 lifting body vehicle, severe lateral pilot-induced oscillations occurred on three occasions in the low - angle of -attack, final-approach, preflare situation. These oscillations were analyzed qualitatively to determine the type and similarity and by a systems analysis to determine the root cause. The analysis was complemented by a piloted simulator study, which verified the results. The systems analysis revealed the presence of a coupled roll-spiral mode which caused the pilots to generate a closed-loop lateral instability in the low-angle -of -attack, preflare flight region. A systems analysis, a piloted simulator study, and flight data showed that the addition of a fixed center fin lessened the pilot-induced-oscillation tendencies in the critical flight region.

Download or read book Flight Evaluation of the Transonic Stability and Control Characteristics of an Airplane Incorporating a Supercritical Wing written by Neil W. Matheny and published by . This book was released on 1978 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A TF-8A airplane was equipped with a transport type supercritical wing and fuselage fairings to evaluate predicted performance improvements for cruise at transonic speeds. A comparison of aerodynamic derivatives extracted from flight and wind tunnel data showed that static longitudinal stability, effective dihedral, and aileron effectiveness, were higher than predicted. The static directional stability derivative was slower than predicted. The airplane's handling qualities were acceptable with the stability augmentation system on. The unaugmented airplane exhibited some adverse lateral directional characteristics that involved low Dutch roll damping and low roll control power at high angles of attack and roll control power that was greater than satisfactory for transport aircraft at cruise conditions. Longitudinally, the aircraft exhibited a mild pitchup tendency. Leading edge vortex generators delayed the onset of flow separation, moving the pitchup point to a higher lift coefficient and reducing its severity.

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).
