The XV-3 tilt rotor emerged from the Army/Air Force convertiplane program of the 50s as a strong contender. However, it faced significant stability problems that discouraged many supporters and threatened to swamp the program. The program was continued by those in industry and Government who believed in the concept and its potential, and were willing to risk their investment. They were rewarded by the discovery of new techniques and the incorporation of new materials technology that made it possible to propose the XV-15 tilt rotor research aircraft project. It was my privilege to successfully advocate Army participation in the program with both funding and personnel. The unique aspects and synergistic values of the Army AARL/AMRDL-NASA interagency participation made this possible. It demonstrated the value of sharing resources in direct partnership toward common goals. Although not yet integrated into Army field strategies, the tilt rotor aircraft holds significant potential for consideration in future missions. The Marine V-22 Osprey demonstrates the rewards of the investment of defense dollars in the tilt rotor research aircraft project. There likely will be more.

Available in PDF, EPUB and Kindle. Book excerpt: The six year development program of the U.S. Army VZ-2 research aircraft, Vertol Division gained extensive experience in the VTOL field. The following conclusions are based upon this exper ience: The technical feasibility of the tilt wing concept has been proven, and a sound basis has been established for the development, design, and construction of a tilt wing aircraft for specific missions. Although new problems were exposed, methods of solving them were indicated. The concentration of hovering controls exclu sively within the propeller-wing assembly, by using full span ailerons for yaw control, differ ential collective pitch for roll control, and monocyclic pitch for pitch control, will elim inate the need for yaw and pitch fans in future models. A more complete comparison and correla tion of test results (NASA flight test, Contrac tor flight test, NASA wind tunnel and Priceton University Long Track data) will provide com prehensive technical data for future designs.

This book was released on 2013-11-01 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Evaluation of Noise Problems Anticipated with Future VTOL Aircraft written by John N. Cole and published by . This book was released on 1967 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential noise problems anticipated with future VTOL aircraft are analyzed and discussed in general terms, and a brief review of the basic principles of noise generation of various types of propulsion systems proposed for VTOL is included. Primary consideration is given to the noise environments produced in areas adjacent to VTOL sites, since they could cause the most serious noise problem limiting the usefulness of VTOL aircraft. Contours of perceived noise levels are compared for different takeoff and landing profiles of 3-4 passenger, 60 passenger, and 25 ton-lift-crane VTOL aircraft. Criteria and methods for assessing the response of communities to noise from V-port operations are discussed along with the problem of detection of military VTOL aircraft by means of noise. Recommendations are given on the requirements for future research on these noise problems with emphasis on the need for considering noise as an integral part of the design, selection, and test of VTOL aircraft.

Download or read book RESEARCH AIRCRAFT XV 5A written by and published by . This book was released on 1966 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report traces the development of the XV-5A research aircraft. The aircraft, though purely experimental, demonstrates the practicability of VTOL lift-fan propelled flight, combined with conversion from the VTOL mode to the CTOL mode and flight in the purely conventional mode. The XV-5A is an all- metal, twin engine, gas-propelled, subsonic, tri-fan, tricycle landing gear, VTOL/CTOL aircraft. It is 44.52 ft. long. Its wingspan is 29.83 ft., and its height to the top of the vertical stabilizer is 14.75 ft. It is powered by two J85-5B turbojet engines. Its two X353-5 wing fans(lift) are 62.5 in. in diameter. Its X373-A nose fan (pitch control, and lift) is 36 in. in diameter and is located in the nose ahead of the cockpit. All fans are operated by diverting engine exhaust gases through crossover ducts to the tip turbines on the rims of the fans. Thrust louvers below the fans control the thrust generated by the revolving fans and exhaust gases. Modifications suggested as a result of tests are being made and possible military applications of lift-fan principles of propulsion to heavy aircraft are being made.
