Flight Dynamics, Simulation, And Control : For ...

A rapid rise in air travel in the past decade is driving the development of newer, more energy-efficient, and malleable aircraft. Typically lighter and more flexible than the traditional rigid body, this new ideal calls for adaptations to some conventional concepts. Flight Dynamics, Simulation, and Control: For Rigid and Flexible Aircraft addresses the intricacies involved in the dynamic modelling, simulation, and control of a selection of aircraft. This book covers the conventional dynamics of rigid aircraft, explores key concepts associated with control configured elastic aircraft, and examines the use of linear and non-linear model-based techniques and their applications to flight control. In addition, it reveals how the principles of modeling and control can be applied to both traditional rigid and modern flexible aircraft.

Flight Dynamics, Simulation, and Control : For ...


This text consists of ten chapters outlining a range of topics relevant to the understanding of flight dynamics, regulation, and control. The book material describes the basics of flight simulation and control, the basics of nonlinear aircraft dynamics, and the principles of control configured aircraft design. It explains how elasticity of the wings/fuselage can be included in the dynamics and simulation, and highlights the principles of nonlinear stability analysis of both rigid and flexible aircraft. The reader can explore the mechanics of equilibrium flight and static equilibrium, trimmed steady level flight, the analysis of the static stability of an aircraft, static margins, stick-fixed and stick-free, modeling of control surface hinge-moments, and the estimation of the elevator for trim.

Written for graduate students and professionals, Aircraft Flight Dynamics and Control provides comprehensive coverage of airplane flight dynamics and control with references to modern treatment throughout. The author overlays the treatment with his experience as a navy fighter pilot and engineering test pilot. Topics include flight dynamics, control systems, linear systems, and control allocation.

The course is invaluable to anyone involved with the development of flight-dynamic models, or with their use, such as in control-law development or flight simulation. It is appropriate for the young engineer that wants a solid foundation in flight dynamics, aerodynamic modeling, and conventional, practical, flight-control-law synthesis, as well as the more established professional that wants both a review of the basic topics plus exposure to more advanced topics such as the flight dynamics of elastic vehicles. The rigorous yet practical treatment of the material will also be of interest to educators in aerospace or mechanical engineering.

Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw. These are collectively known as aircraft attitude, often principally relative to the atmospheric frame in normal flight, but also relative to terrain during takeoff or landing, or when operating at low elevation. The concept of attitude is not specific to fixed-wing aircraft, but also extends to rotary aircraft such as helicopters, and dirigibles, where the flight dynamics involved in establishing and controlling attitude are entirely different.

The motion of a body through a flow is considered, in flight dynamics, as continuum current. In the outer layer of the space that surrounds the body viscosity will be negligible. However viscosity effects will have to be considered when analysing the flow in the nearness of the boundary layer.

FLIGHT Dynamics Software is an engineering tool for flight simulation, and aircraft stability & control analyses. Our software can easily be adapted to your flight dynamics model.

Since it was first published, Flight Dynamics has offered a new approach to the science and mathematics of aircraft flight, unifying principles of aeronautics with contemporary systems analysis. Now updated and expanded, this authoritative book by award-winning aeronautics engineer Robert Stengel presents traditional material in the context of modern computational tools and multivariable methods. Special attention is devoted to models and techniques for analysis, simulation, evaluation of flying qualities, and robust control system design.Using common notation and not assuming a strong background in aeronautics, Flight Dynamics will engage a wide variety of readers, including aircraft designers, flight test engineers, researchers, instructors, and students. It introduces principles, derivations, and equations of flight dynamics as well as methods of flight control design with frequent reference to MATLAB functions and examples. Topics include aerodynamics, propulsion, structures, flying qualities, flight control, and the atmospheric and gravitational environment.The second edition of Flight Dynamics features up-to-date examples; a new chapter on control law design for digital fly-by-wire systems; new material on propulsion, aerodynamics of control surfaces, and aeroelastic control; many more illustrations; and text boxes that introduce general mathematical concepts.

A major barrier to certification and public acceptance of emerging distributed electric propulsion (DEP) aircraft is their noise. Like conventional helicopters, accurate noise prediction of DEP aircraft requires accurate modeling of realistic flight dynamics and controls. Furthermore, aspects unique to DEP aircraft must be modeled, such as variable rotor speed for thrust control, and unsteady aerodynamics arising from rotor thrust control and aerodynamic interactions between rotors and the airframe. To address these needs, this paper describes the development and software coupling of a noise prediction system for DEP aircraft. This system is demonstrated for maneuvering flight simulations consisting of a roll attitude doublet in low speed forward flight, for two rotor thrust control schemes: variable rotor speed and variable collective pitch. Loading noise levels for this configuration generally exceeded thickness noise levels. For a single rotor, loading noise modulated with thrust, regardless of the cause of the time variation of loading (variable rotor speed or collective pitch). However, the range of modulation was greater for the variable rotor speed case than for variable pitch. Less modulation is observed in the total noise for all rotors, because the rotor thrusts must vary to balance the aircraft. Interference patterns are observed for the constant speed case due to coherent phase relations between the rotors, whereas the noise of the variable speed rotors does not add coherently. 041b061a72
