Few technological advances have affected the lives and dreams of individuals and the operations of companies and governments as much as the continuing development of flight. From space exploration to package transport, from military transport to passenger helicopter use, from passenger jumbo jets to tilt-rotor commuter planes, the future of flying is still rapidly developing. The essays in this volume survey the state of progress along several fronts of this constantly evolving frontier. Five eminent authorities assess prospects for the future of rotary-wing aircraft, large passenger aircraft, commercial aviation, manned spaceflight, and defense aerospace in the post-Cold War era.

Assess prospects for innovation and competition in the military combat-aircraft industry. o

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

A fascinating and authoritative narrative history of the V-22 Osprey, revealing the inside story of the most controversial piece of military hardware ever developed for the United States Marine Corps. When the Marines decided to buy a helicopter-airplane hybrid “tiltrotor” called the V-22 Osprey, they saw it as their dream machine. The tiltrotor was the aviation equivalent of finding the Northwest Passage: an aircraft able to take off, land, and hover with the agility of a helicopter yet fly as fast and as far as an airplane. Many predicted it would reshape civilian aviation. The Marines saw it as key to their very survival. By 2000, the Osprey was nine years late and billions over budget, bedeviled by technological hurdles, business rivalries, and an epic political battle over whether to build it at all. Opponents called it one of the worst boondoggles in Pentagon history. The Marines were eager to put it into service anyway. Then two crashes killed twenty-three Marines. They still refused to abandon the Osprey, even after the Corps’ own proud reputation was tarnished by a national scandal over accusations that a commander had ordered subordinates to lie about the aircraft’s problems. Based on in-depth research and hundreds of interviews, The Dream Machine recounts the Marines’ quarter-century struggle to get the Osprey into combat. Whittle takes the reader from the halls of the Pentagon and Congress to the war zone of Iraq, from the engineer’s drafting table to the cockpits of the civilian and Marine pilots who risked their lives flying the Osprey—and sometimes lost them. He reveals the methods, motives, and obsessions of those who designed, sold, bought, flew, and fought for the tiltrotor. These stories, including never before published eyewitness accounts of the crashes that made the Osprey notorious, not only chronicle an extraordinary chapter in Marine Corps history, but also provide a fascinating look at a machine that could still revolutionize air travel.
