Book Description
This monograph is a testament to the efforts of many people overcoming multiple technical challenges encountered while developing the XV-15 tilt rotor research aircraft. The Ames involvement with the tilt rotor aircraft began in 1957 with investigations of the performance and dynamic behavior of the Bell XV-3 tilt rotor aircraft. At that time, Ames Research Center was known as the Ames Aeronautical Laboratory of the National Advisory Committee for Aeronautics (NACA). As we approach the new millennium, and after more than 40 years of effort and the successful completion of our initial goals, it is appropriate to reflect on the technical accomplishments and consider the future applications of this unique aircraft class, the tilt rotor. The talented engineers, technicians, managers, and leaders at Ames have worked hard with their counterparts in the U.S. rotorcraft industry to overcome technology barriers and to make the military and civil tilt rotor aircraft safer, environmentally acceptable, and more efficient. The tilt rotor aircraft combines the advantages of vertical takeoff and landing capabilities, inherent to the helicopter, with the forward speed and range of a fixed wing turboprop airplane. Our studies have shown that this new vehicle type can provide the aviation transportation industry with the flexibility for highspeed, long-range flight, coupled with runway-independent operations, thus having a significant potential to relieve airport congestion. We see the tilt rotor aircraft as an element of the solution to this growing air transport problem.

Book Description
This monograph is a testament to the efforts of many people overcoming multiple technical challenges encountered while developing the XV-15 tilt rotor research aircraft. It is a comprehensive and detailed documentation of more than 40 years of effort at the NASA Ames Research Center designing this unique class of aircraft. The tilt rotor aircraft combines the advantages of vertical takeoff and landing capabilities, inherent to the helicopter, with the forward speed and range of a fixed wing turboprop airplane. NASA sees the tilt rotor as a new type of vehicle that will provide flexibility for high-speed, long-range flight, coupled with runway-independent operations. It takes the reader through the entire history, culminating with the first production of the V-22 Osprey, built for the U.S. Marine Corps, and the BA609 by Bell-Augusta. This publication takes the reader through the early ideas of Leonardo da Vinci through the search for an aircraft with Vertical Takeoff and Landing (VTOL) capabilities. There is abundant historical data about numerous innovative flying machines devised during the 1920s and 1930s, and German projects by Focke-Achgelis and Focke-Wulf. The publication includes illustrations from the 1930 flying machine patent of G. Lehberger, as well as the convertible aircraft patent of Haviland H. Platt (1955). The publication also describes how the XV-3 tilt rotor emerged from the Army/Air Force convertiplane program of the 1950s, and the evolution of tilt rotor, tilt wing, lift-fan, and direct lift versions and the evolution of the XV-3 program, which began in 1951. Flight tests are described in great detail, explaining the problems of stability. The development of tilt rotor aircraft technology involved some of the same factors that led to other important aeronautical accomplishments of this century. The vision of a few individuals in search of a practical and efficient new aircraft design, commitment to their goals, and their willingness to continue to pursue their objective while encountering major technical problems and programmatic challenges were critical ingredients in this tale. However, the unique aspect of the tilt rotor story was the combined Government and industry focused effort that was sustained for over four decades to explore, comprehend, develop, and refine this technology. The remarkable product of the investment of public and private funds, and the efforts of the people dedicated to the concept, is an aircraft type that will have an impact on civil and military aviation that will rival the introduction of the practical helicopter more than 60 years ago.

Book Description
The Book The behaviour of helicopters and tiltrotor aircraft is so complex that understanding the physical mechanisms at work in trim, stability and response, and thus the prediction of Flying Qualities, requires a framework of analytical and numerical modelling and simulation. Good Flying Qualities are vital for ensuring that mission performance is achievable with safety and, in the first and second editions of Helicopter Flight Dynamics, a comprehensive treatment of design criteria was presented, relating to both normal and degraded Flying Qualities. Fully embracing the consequences of Degraded Flying Qualities during the design phase will contribute positively to safety. In this third edition, two new Chapters are included. Chapter 9 takes the reader on a journey from the origins of the story of Flying Qualities, tracing key contributions to the developing maturity and to the current position. Chapter 10 provides a comprehensive treatment of the Flight Dynamics of tiltrotor aircraft; informed by research activities and the limited data on operational aircraft. Many of the unique behavioural characteristics of tiltrotors are revealed for the first time in this book. The accurate prediction and assessment of Flying Qualities draws on the modelling and simulation discipline on the one hand and testing practice on the other. Checking predictions in flight requires clearly defined mission tasks, derived from realistic performance requirements. High fidelity simulations also form the basis for the design of stability and control augmentation systems, essential for conferring Level 1 Flying Qualities. The integrated description of flight dynamic modelling, simulation and flying qualities of rotorcraft forms the subject of this book, which will be of interest to engineers practising and honing their skills in research laboratories, academia and manufacturing industries, test pilots and flight test engineers, and as a reference for graduate and postgraduate students in aerospace engineering.
