Aircraft Performance: An Engineering Approach, Second Edition introduces flight performance analysis techniques of fixed-wing air vehicles, particularly heavier-than-aircraft. It covers maximum speed, absolute ceiling, rate of climb, range, endurance, turn performance, and takeoff run.
Enabling the reader to analyze the performance and flight capabilities of an aircraft by utilizing only the aircraft weight data, geometry, and engine characteristics, this book covers the flight performance analysis for both propeller-driven and jet aircraft. The second edition features new content on vertical takeoff and landing, UAV launch, UAV recovery, use of rocket engine as the main engine, range for electric aircraft, electric engine, endurance for electric aircraft, gliding flight, pull-up, and climb-turn. In addition, this book includes end-of-chapter problems, MATLAB(R) code and examples, and case studies to enhance and reinforce student understanding.
This book is intended for senior undergraduate aerospace students taking courses in Aircraft Performance, Flight Dynamics, and Flight Mechanics.
Instructors will be able to utilize an updated Solutions Manual and Figure Slides for their course.
