Flight Performance Of Aircraft

This book discusses aircraft flight performance, focusing on commercial aircraft but also considering examples of high-performance military aircraft. The framework is a multidisciplinary engineering analysis, fully supported by flight simulation, with software validation at several levels. The book covers topics such as geometrical configurations, configuration aerodynamics and determination of aerodynamic derivatives, weight engineering, propulsion systems (gas turbine engines and propellers), aircraft trim, flight envelopes, mission analysis, trajectory optimisation, aircraft noise, noise trajectories and analysis of environmental performance. A unique feature of this book is the discussion and analysis of the environmental performance of the aircraft, focusing on topics such as aircraft noise and carbon dioxide emissions.

This text describes the basic forces which dictate and decide the performance of an aircraft. It is aimed at pilots and flight-test engineers seeking answers to questions of flight mechanics. Referring to real-life situations, performance analysis is presented for most phases of flying, including takeoff, climb, cruise, turn, descent and landing. To improve confidence in dealing with these situations, a list of problems is provided at the end of each chapter to encourage trouble-shooting and theory comprehension. Charts, figures and references reinforce and complement the text throughout.

Calculation and optimisation of flight performance is required to design or select new aircraft, efficiently operate existing aircraft, and upgrade aircraft. It provides critical data for aircraft certification, accident investigation, fleet management, flight regulations and safety. This book presents an unrivalled range of advanced flight performance models for both transport and military aircraft, including the unconventional ends of the envelopes. Topics covered include the numerical solution of supersonic acceleration, transient roll, optimal climb of propeller aircraft, propeller performance, long-range flight with en-route stop, fuel planning, zero-gravity flight in the atmosphere, VSTOL operations, ski jump from aircraft carrier, optimal flight paths at subsonic and supersonic speed, range-payload analysis of fixed- and rotary wing aircraft, performance of tandem helicopters, lower-bound noise estimation, sonic boom, and more. This book will be a valuable text for undergraduate and post-graduate level students of aerospace engineering. It will also be an essential reference and resource for practicing aircraft engineers, aircraft operations managers and organizations handling air traffic control, flight and flying regulations, standards, safety, environment, and the complex financial aspects of flying aircraft. Unique coverage of fixed and rotary wing aircraft in a unified manner, including optimisation, emissions control and regulation. Ideal for students, aeronautical engineering capstone projects, and for widespread professional reference in the aerospace industry. Comprehensive coverage of computer-based solution of aerospace engineering problems; the critical analysis of performance data; and case studies from real world engineering experience. Supported by end of chapter exercises

This undergraduate textbook offers a unique introduction to steady flight and performance for fixed-wing aircraft from a twenty-first-century flight systems perspective. Emphasizing the interplay between mathematics and engineering, it fully explains the fundamentals of aircraft flight and develops the basic algebraic equations needed to obtain the conditions for gliding flight, level flight, climbing and descending flight, and turning flight. It covers every aspect of flight performance, including maximum and minimum air speed, maximum climb rate, minimum turn radius, flight ceiling, maximum range, and maximum endurance. Steady Aircraft Flight and Performance features in-depth case studies of an executive jet and a general aviation propeller-driven aircraft, and uses MATLAB to compute and illustrate numerous flight performance measures and flight envelopes for each. Requiring only sophomore-level calculus and physics, it also includes a section on translational flight dynamics that makes a clear connection between steady flight and flight dynamics, thereby providing a bridge to further study. Offers the best introduction to steady aircraft flight and performance Provides a comprehensive treatment of the full range of steady flight conditions Covers steady flight performance and flight envelopes, including maximum and minimum air speed, maximum climb rate, minimum turn radius, and flight ceiling Uses mathematics and engineering to explain aircraft flight Features case studies of actual aircraft, illustrated using MATLAB Seamlessly bridges steady flight and translational flight dynamics

Pilots, aviation students, kitplane builders, aircraft fleet operators and aeronautical engineers can all determine how their propeller-driven airplanes will perform, under any conditions, by using the step-by-step bootstrap approach introduced in this book. A few routine flying manoeuvres (climbs, glides, a level speed run) will give the necessary nine numbers. High-school level calculations then give performance numbers with much greater detail and accuracy than many other methods - for the reader's individual aircraft.

Describes the principles and equations required for evaluating the performance of an aircraft.

Based on a 15-year successful approach to teaching aircraft flight mechanics at the US Air Force Academy, this text explains the concepts and derivations of equations for aircraft flight mechanics. It covers aircraft performance, static stability, aircraft dynamics stability and feedback control.
