Book excerpt: There is a requirement for rigorous analytical tools that can be used to analyse the flying and handling qualities deficiencies of novel personal-air-vehicles (PAV), prior to experimental flight testing. In more recent years, ground-based simulation has become a critical component of aircraft-level design and a core requirement of the procuring activity. For small footprint, personal, air-vehicle systems the analysis of pilot workload has often relied, exclusively, on pilot-in-the-loop flight test and full immersion simulation experiments. In order to facilitate the preliminary stages of aircraft design there is need for an off-line, quantitative, rating method that can be brought to bear in the absence of an adequate pilot representation. The prediction of aircraft handling qualities is complicated, however, by the need to accurately assess pilot effort. This thesis provides a comprehensive analysis of the control design and handling qualities of a manually controlled, novel, PAV. The handling qualities of the vehicle are assessed, first by reference to the Rotorcraft Aeronautical Design Standard (ADS33-E-PRF), then by pilot/vehicle analysis using models of pursuit, compensatory, and regressive human pilot behaviour. In the latter case, handling qualities levels, pilot-induced oscillation rating levels, and tracking performance are predicted. Consideration is given to both linear and nonlinear pilot/vehicle behaviour. Approximate bounds on the off-nominal linear vehicle model stability derivatives are explored and the expected operational and service flights envelope, temporal and corridor constraints examined. Finally, validation of the proposed pilot modelling techniques and rating criterion are presented, and the use of traditional rotary and fixed-wing HQ rating boundaries are examined with application to a prototype, rotary-wing PAV system. The research work presented in this dissertation provides a means of (1) identifying the feasible design space of a unique aircraft based upon predicted and expected levels of handling qualities and performance, and (2) determining compliance with both civil and (where required) military requirements for manned operation of PAV systems. 2 The research presented may provide a useful template for assessing the handling qualities of more novel, personal air-vehicle concepts prior to pilot-in-the-loop simulation or flight testing.

This book was released on 1968 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although rating scales of varied forms have been widely used to estimate and evaluate handling qualities over the past decade, a number of deficiencies in both method and data base have been apparent. The investigation was aimed at overcoming many of these deficiencies by attempting to resolve the difficulties experienced with rating scales themselves, and by extending and adding to already existing relationships between ratings and pilot/vehicle system parameters. Rating scales have come under increasing criticism for problems such as wording ambiguity, the dual mission character of some scales, the nonuniformity in the distribution of descriptors across the scale, and the misuse of scales which has occurred when ratings have been averaged. Psychometric methods provide an approach to these problems, and were used to scale several phrases descriptive of vehicle handling qualities. Thus, quantitative characteristics were derived for contemporary scales through the use of the Method of Successive Intervals. An experiment was conducted which added to available data relating Cooper ratings and pilot/vehicle parameters, and which also tested some potential alternate scale candidates. The correlation results indicate that ratings are probably based on performance and the degree of difficulty experienced in maintaining the performance. The difficulty is most easily represented by the pilot equalization required and the vehicle stick characteristics. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Flight Dynamics takes a new approach to the science and mathematics of aircraft flight, unifying principles of aeronautics with contemporary systems analysis. While presenting traditional material that is critical to understanding aircraft motions, it does so in the context of modern computational tools and multivariable methods. Robert Stengel devotes particular attention to models and techniques that are appropriate for analysis, simulation, evaluation of flying qualities, and control system design. He establishes bridges to classical analysis and results, and explores new territory that was treated only inferentially in earlier books. This book combines a highly accessible style of presentation with contents that will appeal to graduate students and to professionals already familiar with basic flight dynamics. Dynamic analysis has changed dramatically in recent decades, with the introduction of powerful personal computers and scientific programming languages. Analysis programs have become so pervasive that it can be assumed that all students and practicing engineers working on aircraft flight dynamics have access to them. Therefore, this book presents the principles, derivations, and equations of flight dynamics with frequent reference to MATLAB functions and examples. By using common notation and not assuming a strong background in aeronautics, Flight Dynamics will engage a wide variety of readers. Introductions to aerodynamics, propulsion, structures, flying qualities, flight control, and the atmospheric and gravitational environment accompany the development of the aircraft's dynamic equations.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive approach to the air vehicle design process using the principles of systems engineering Due to the high cost and the risks associated with development, complex aircraft systems have become a prime candidate for the adoption of systems engineering methodologies. This book presents the entire process of aircraft design based on a systems engineering approach from conceptual design phase, through to preliminary design phase and to detail design phase. Presenting in one volume the methodologies behind aircraft design, this book covers the components and the issues affected by design procedures. The basic topics that are essential to the process, such as aerodynamics, flight stability and control, aero-structure, and aircraft performance are reviewed in various chapters where required. Based on these fundamentals and design requirements, the author explains the design process in a holistic manner to emphasise the integration of the individual components into the overall design. Throughout the book the various design options are considered and weighed against each other, to give readers a practical understanding of the process overall. Readers with knowledge of the fundamental concepts of aerodynamics, propulsion, aero-structure, and flight dynamics will find this book ideal to progress towards the next stage in their understanding of the topic. Furthermore, the broad variety of design techniques covered ensures that readers have the freedom and flexibility to satisfy the design requirements when approaching real-world projects. Key features: • Provides full coverage of the design aspects of an air vehicle including: aeronautical concepts, design techniques and design flowcharts • Features end of chapter problems to reinforce the learning process as well as fully solved design examples at component level • Includes fundamental explanations for aeronautical engineering students and practicing engineers • Features a solutions manual to sample questions on the book’s companion website Companion website - www.wiley.com/go/sadraey

Available in PDF, EPUB and Kindle. Book excerpt: The report discusses the assessment of handling quality characteristics Since handling qualities deal with the teamed product, both elements -- pilot and airplane -- must be represented in order to assess handling qualities. One cannot simply examine the time history of the response of an airplane to a particular control input and assess, in an intuitive engineering sense, whether such a response will be good or bad when employed by a pilot in a mission. Rather, it is necessary to examine the suitability of the pilot-airplane combination for accomplishing the mission. Some of the important factors which affect the quality or applicability of pilot assessment of the handling qualities of airborne vehicles are discussed. (Author).
