A guide to flight simulator design, covering the modelling, algorithms and software which underpin flight simulation. It also covers the mathematical modelling and software which underpin flight simulation, and techniques used in motion platform development, the design of instructor stations and validation and qualification of simulator systems."Principles of Flight Simulation" is a comprehensive guide to flight simulator design, covering the modelling, algorithms and software which underpin flight simulation. The book covers the mathematical modelling and software which underpin flight simulation. The detailed equations of motion used to model aircraft dynamics are developed and then applied to the simulation of flight control systems and navigation systems. Real-time computer graphics algorithms are developed to implement aircraft displays and visual systems, covering OpenGL and OpenSceneGraph. The book also covers techniques used in motion platform development, the design of instructor stations and validation and qualification of simulator systems. An exceptional feature of "Principles of Flight Simulation" is access to a complete suite of software to enable experienced engineers to develop their own flight simulator - something that should be well within the capability of many university engineering departments and research organisations.; It is based on C code modules from an actual flight simulator developed by the author, along with lecture material from lecture series given by the author at Cranfield University and the University of Sheffield. It brings together mathematical modeling, computer graphics, real-time software, flight control systems, avionics and simulator validation into one of the faster growing application areas in engineering. It features full colour plates of images and photographs. "Principles of Flight Simulation" will appeal to senior and postgraduate students of system dynamics, flight control systems, avionics and computer graphics, as well as engineers in related disciplines covering mechanical, electrical and computer systems engineering needing to develop simulation facilities.About the Author Preface 1 Introduction 1.1 Historical Perspective 1.2 The Case for Simulation 1.3 The Changing Role of Simulation 1.4 The Organization of a Flight Simulator 1.5 The Concept of Real-time Simulation 1.6 Pilot Cues 1.7 Training versus Simulation 1.8 Examples of Simulation References 2 Principles of Modelling 2.1 Modelling Concepts 2.2 Newtonian Mechanics 2.3 Axes Systems 2.4 Differential Equations 2.5 Numerical Integration 2.6 Real-time Computing 2.7 Data Acquisition 2.8 Flight Data 2.9 Interpolation 2.10 Distributed Systems 2.11 A Real-time Protocol 2.12 Problems in Modelling References 3 Aircraft Dynamics 3.1 Principles of Flight Modelling 3.2 The Atmosphere 3.3 Forces 3.4 Moments 3.5 Axes Systems 3.6 Quaternions 3.7 Equations of Motion 3.8 Propulsion 3.9 The Landing Gear 3.10 The Equations Collected 3.11 The Equations Revisited - Long Range Navigation References 4 Simulation of Flight Control Systems 4.1 The Laplace Transform 4.2 Simulation of Transfer Functions 4.3 PID Control Systems 4.4 Trimming 4.5 Aircraft Flight Control Systems 4.6 The Turn Coordinator and the Yaw Damper 4.7 The Auto-throttle 4.8 Vertical Speed Management 4.9 Altitude Hold 4.10 Heading Hold 4.11 Localizer Tracking 4.12 Auto-land Systems 4.13 Flight Management Systems References 5 Aircraft Displays 5.1 Principles of Display Systems 5.2 Line Drawing 5.3 Character Generation 5.4 D Graphics Operations 5.5 Textures 5.6 OpenGL 5.7 Simulation of Aircraft Instruments 5.8 Simulation of EFIS Displays 5.9 Head-up Displays References 6 Simulation of Aircraft Navigation Systems 6.1 Principles of Navigation 6.2 Navigation Computations 6.3 Map Projections 6.4 Primary Flight Information 6.5 Automatic Direction Finding (ADF) 6.6 VHF Omnidirectional Range (VOR) 6.7 Distance Measuring Equipment (DME) 6.8 Instrument Landing Systems (ILS) 6.9 The Flight Director 6.10 Inertial Navigation Systems 6.11 Global Positioning Systems References Further Reading 7 Model Validation 7.1 Simulator Qualification and Approval 7.2 Model Validation Methods 7.3 Latency 7.4 Performance Analysis 7.5 Longitudinal Dynamics 7.6 Lateral Dynamics 7.7 Model Validation in Perspective References 8 Visual Systems 8.1 Background 8.2 The Visual System Pipeline 8.3 D Graphics Operations 8.4 Real-time Image Generation 8.5 Visual Database Management 8.6 Projection Systems 8.7 Problems in Visual Systems References 9 The Instructor Station 9.1 Education, Training and Instruction 9.2 Part-task Training and Computer-based Training 9.3 The Role of the Instructor 9.4 Designing the User Interface 9.5 Real-time Interaction 9.6 Map Displays 9.7 Flight Data Recording 9.8 Scripting References 10 Motion Systems 10.1 Motion or No Motion? 10.2 Physiological Aspects of Motion 10.3 Actuator Configurations 10.4 Equations of Motion 10.5 Implementation of a Motion System 10.6 Hydraulic Actuation 10.7 Modelling Hydraulic Actuators 10.8 Limitations of Motion Systems 10.9 Future Motion Systems References Index
