This book was released on 2018 with total page 308 pages. Available in PDF, EPUB and Kindle. 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.
Download or read book Stability and Control of Conventional and Unconventional Aerospace Vehicle Configurations written by Bernd Chudoba and published by Springer. This book was released on 2019-07-23 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces a stability and control methodology named AeroMech, capable of sizing the primary control effectors of fixed wing subsonic to hypersonic designs of conventional and unconventional configuration layout. Control power demands are harmonized with static-, dynamic-, and maneuver stability requirements, while taking the six-degree-of-freedom trim state into account. The stability and control analysis solves the static- and dynamic equations of motion combined with non-linear vortex lattice aerodynamics for analysis. The true complexity of addressing subsonic to hypersonic vehicle stability and control during the conceptual design phase is hidden in the objective to develop a generic (vehicle configuration independent) methodology concept. The inclusion of geometrically asymmetric aircraft layouts, in addition to the reasonably well-known symmetric aircraft types, contributes significantly to the overall technical complexity and level of abstraction. The first three chapters describe the preparatory work invested along with the research strategy devised, thereby placing strong emphasis on systematic and thorough knowledge utilization. The engineering-scientific method itself is derived throughout the second half of the book. This book offers a unique aerospace vehicle configuration independent (generic) methodology and mathematical algorithm. The approach satisfies the initial technical quest: How to develop a ‘configuration stability & control’ methodology module for an advanced multi-disciplinary aerospace vehicle design synthesis environment that permits consistent aerospace vehicle design evaluations?

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a readable introduction to handling qualities, the combination of pilot acceptability and piloted performance with stability and control. It adopts the analytical and qualitative standpoints needed for handling qualities analysis and design of fixed-wing aircraft. Although there are several texts on stability and control, until now none has provided insight into the piloting concerns that have affected the success of recent fly-by-wire aircraft developments.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Adverse aircraft-pilot coupling (APC) events include a broad set of undesirable and sometimes hazardous phenomena that originate in anomalous interactions between pilots and aircraft. As civil and military aircraft technologies advance, interactions between pilots and aircraft are becoming more complex. Recent accidents and other incidents have been attributed to adverse APC in military aircraft. In addition, APC has been implicated in some civilian incidents. This book evaluates the current state of knowledge about adverse APC and processes that may be used to eliminate it from military and commercial aircraft. It was written for technical, government, and administrative decisionmakers and their technical and administrative support staffs; key technical managers in the aircraft manufacturing and operational industries; stability and control engineers; aircraft flight control system designers; research specialists in flight control, flying qualities, human factors; and technically knowledgeable lay readers.
