This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Download or read book Unmanned Aircraft Design written by Mohammad Sadraey and published by Morgan & Claypool Publishers. This book was released on 2017-09-19 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides fundamental principles, design procedures, and design tools for unmanned aerial vehicles (UAVs) with three sections focusing on vehicle design, autopilot design, and ground system design. The design of manned aircraft and the design of UAVs have some similarities and some differences. They include the design process, constraints (e.g., g-load, pressurization), and UAV main components (autopilot, ground station, communication, sensors, and payload). A UAV designer must be aware of the latest UAV developments; current technologies; know lessons learned from past failures; and they should appreciate the breadth of UAV design options. The contribution of unmanned aircraft continues to expand every day and over 20 countries are developing and employing UAVs for both military and scientific purposes. A UAV system is much more than a reusable air vehicle or vehicles. UAVs are air vehicles, they fly like airplanes and operate in an airplane environment. They are designed like air vehicles; they have to meet flight critical air vehicle requirements. A designer needs to know how to integrate complex, multi-disciplinary systems, and to understand the environment, the requirements and the design challenges and this book is an excellent overview of the fundamentals from an engineering perspective. This book is meant to meet the needs of newcomers into the world of UAVs. The materials are intended to provide enough information in each area and illustrate how they all play together to support the design of a complete UAV. Therefore, this book can be used both as a reference for engineers entering the field or as a supplementary text for a UAV design course to provide system-level context for each specialized topic.

This book was released on 1989 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new concept is developed for an unmanned aerial vehicle (UAV) configured with a tip-jet driven, two-bladed, stoppable rotor and circulation control airfoils. The conceptual design of the Tipjet Vertical Takeoff and Landing (VTOL) UAV is presented, and vehicle performance is evaluated for three mid-range UAV Navy missions: Tactical Reconnaissance, Over-the-Horizon Targeting, and Combat Support Reconnaissance. Vehicle performance predictions are presented for hover and low-speed, rotary-wing flight, for conversion between rotary-wing and fixed-wing flight, and for fixed-wing flight. Requirements for shipboard support of the vehicle are outlined. Mission specific equipment is described including size, weight, and power requirements. Standard design methods are applied to conduct a detailed mission performance analysis for the conceptual design. The analysis results indicate that the 1200-1b Tipjet VTOL UAV is a viable candidate vehicle for the specified missions. Moreover, the concept is directly applicable to much larger UAVs that will greatly enhance naval warfare capabilities. Part 1 of Volume I presents the conceptual design for the Tipjet VTOL UAV along with vehicle performance analysis for the designed missions. Part 2 of Volume I presents the detailed engine and vehicle performance data. This proprietary information is available upon request to qualified agencies.

This book was released on 2006 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Unmanned aerial vehicles possessing vertical takeoff and landing capabilities are receiving growing interest within the aerospace industry, as these aircraft can be operated in areas and on missions that preclude the use of conventional aircraft. This thesis presents the development and analysis of the triple tilt-duct aircraft configuration, an aircraft design suited for future generations of VTOL UAVs. The development of a conceptual design for a small-scale, "proof of concept" tilt-duct UAV is presented, culminating in a description of the final conceptual design. The methodology for a detailed analysis of the performance and the stability and control characteristics of the tilt-duct UAV design is outlined, along with the results from these analyses. The tilt-duct UAV has good stability and handling characteristics when in horizontal flight mode, but is highly unstable when hovering or in vertical flight mode. A study of the motion of the tilt-duct aircraft during transition maneuvers between horizontal and vertical flight modes is also presented; schemes for performing optimal transition maneuvers and maintaining adequate pitch control during the transitions are given as well. A flight simulation model was utilized to test the performance and stability and control of the tilt-duct UAV. Though it was not possible to accurately simulate transition maneuvers with the software package used, it was possible to obtain reasonable measurements of the aircraft's performance and response to control inputs. An outlook for the triple tilt-duct configuration is given, along with suggestions for future research. It is felt that the triple tilt-duct configuration is a viable design for future VTOL aircraft"--Abstract, leaf iii.
