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: 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: A study was conducted to design an experimental flight test program for the Total In-Flight Simulator CTIFS) directed toward the interface between flying qualities requirements and flight control system design criteria. The eventual goal is to provide an interpretation or translation of flying qualities requirements for use by the flight control system designer. Specifically, an angle of attack and pitch rate command system matrix involving both short term and long term dynamics are specified for evaluation. A major objective of the research was to demonstrate that flying qualities criteria and flight control system configuration or architecture can be independent. Finally, additional configurations are proposed to evaluate the efficacy of dynamic decoupling.

Download or read book A Design Procedure and Handling quality Criteria for Lateral directional Flight Control Systems written by Gunter Stein and published by . This book was released on 1971 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The program develops a practical design procedure for aircraft augmentation systems based on quadratic optimal control technology and handling-quality-oriented cost functionals. The procedure is applied to the design of a lateral-directional control system for the F4C aircraft. The design criteria, design procedure, and final control system are validated with a program of formal pilot evaluation experiments. These use 5 x 2 x 3 mixed-design analysis of variance. A reformulated optimal model-following control problem is used as the cornerstone for the procedure. Design criteria are expressed as model differential equations satisfying available handling-quality data. The reformulation includes optimality over multiple flight conditions and constant gain and measurement realizability constraints. A computational algorithm is developed to solve the new optimization problem. The algorithm successfully handled 20th-order F4C lateral-axes dynamics and optimized five flight conditions simultaneously. The results of the validation experiments were fully positive with strong correlation between performance and pilot opinion data. (Author).

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.

This book was released on 2018-09-24 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A maximum-likelihood output-error parameter estimation technique is used to obtain stability and control derivatives for the NASA Dryden Flight Research Center SR-71A airplane and for configurations that include experiments externally mounted to the top of the fuselage. This research is being done as part of the envelope clearance for the new experiment configurations. Flight data are obtained at speeds ranging from Mach 0.4 to Mach 3.0, with an extensive amount of test points at approximately Mach 1.0. Pilot-input pitch and yaw-roll doublets are used to obtain the data. This report defines the parameter estimation technique used, presents stability and control derivative results, and compares the derivatives for the three configurations tested. The experimental configurations studied generally show acceptable stability, control, trim, and handling qualities throughout the Mach regimes tested. The reduction of directional stability for the experimental configurations is the most significant aerodynamic effect measured and identified as a design constraint for future experimental configurations. This report also shows the significant effects of aircraft flexibility on the stability and control derivatives.Moes, Timothy R. and Iliff, KennethArmstrong Flight Research CenterCONTROLLABILITY; SR-71 AIRCRAFT; MAXIMUM LIKELIHOOD ESTIMATES; DIRECTIONAL STABILITY; AIRCRAFT STABILITY; SUBSONIC SPEED; YAW; MACH NUMBER; ERROR ANALYSIS; AERODYNAMICS
