This book was released on 1984 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis assists those evaluating helicopter design to make preliminary judgements about the feasibility of new designs. By using the computer program developed in this thesis, a designer can produce estimates for power requirements, endurance velocity, rate of climb, range velocity, hover ceiling, and service ceiling versus main rotor radius. These estimates can also be examined for the effects of changes in main rotor radius, chord, and rotational velocity. Keywords include: Helicopter design, Helicopter performance, Helicopter flight performance, and Helicopter performance factors.

Download or read book Automated Low-Altitude Air Delivery written by Johann C. Dauer and published by Springer Nature. This book was released on 2021-11-02 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates Unmanned Aircraft Systems (UAS) with a payload capacity of one metric ton for transportation. The authors provide a large variety of perspectives–from economics to technical realization. With the focus on such heavy-lift cargo UAS, the authors consider recently established methods for approval and certification, which they expect to be disruptive for unmanned aviation. In particular, the Specific Operations Risk Assessment (SORA) and its impact on the presented technological solutions and operational concepts are studied. Starting with the assumption of an operation over sparsely populated areas and below common air traffic, diverse measures to further reduce operational risks are proposed. Operational concepts derived from logistics use-cases set the context for an in-depth analysis including aircraft and system design, safe autonomy as well as airspace integration and datalinks. Results from simulations and technology demonstrations are presented as a proof of concept for solutions proposed in this book.

Book Synopsis Principles of Helicopter Flight Dynamics by : Yihua Cao
Download or read book Principles of Helicopter Flight Dynamics written by Yihua Cao and published by . This book was released on 2009 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight dynamics create important research problems in the process of helicopter design. They involve advanced design ideas and engineering technology theories. This book concerns flight theory and research methods for helicopter flight science and technology. The contents include the fundamentals of rotor aerodynamics, helicopter trim, helicopter stability and control, and helicopter performance analyses. The book also lokks at the kinematics, dynamics, control, and aerodynamics of the helicopter during maneuvering flight. With an emphasis on the physical concepts, the characteristics of rotor flapping, theoretical analyses and numerical simulation methods for helicopter flight mechanics are detail described in detail. The book is primarily intended for senior undergraduates and postgraduates who major in aerospace engineering. It is also a good reference book for helicopter engineers interested design and operational engineering. It lays a foundation for the study of helicopter aeromechanics.
Book Synopsis A Preliminary Design Study of a Quiet Light Observation Helicopter by : Eugene L. Brown
Download or read book A Preliminary Design Study of a Quiet Light Observation Helicopter written by Eugene L. Brown and published by . This book was released on 1969 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents the results of a preliminary design study and an analytical investigation of noise-reduction measures for the OH-58A Light Observation Helicopter (LOH). The purpose was to establish what degree of quieting is possible and what penalties in performance and mission capabilities are associated with the application of noise-reduction measures. Design data are presented for four configurations. Two are test/demonstrator versions suitable for a flight-test program to verify the predicted noise reductions. The other two configurations incorporate design changes to give an operational quiet LOH the same payload and performance as the OH-58A. Design data, performance, and noise levels for all the study configurations are summarized. A program of design modification and tests to confirm the predicted noise reductions is presented.

Book Synopsis Foundations of Helicopter Flight by : S. Newman
Download or read book Foundations of Helicopter Flight written by S. Newman and published by Butterworth-Heinemann. This book was released on 1994-04-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique design problems which helicopters produce are many and complex. Through practical examples and illustrated case studies, supported by all the relevant theory, this primer text provides an accessible introduction which guides the reader through the theory, design, construction and operation of helicopters. Fundamental performance and control equations are developed, from which the book explores the rotor aerodynamic and dynamic characteristics of helicopters. Example calculations and performance predictions, reflecting current practice, show how to assess the feasibility of a design.
Book Synopsis Hand-Held Computer Programs for Preliminary Helicopter Design by :
Download or read book Hand-Held Computer Programs for Preliminary Helicopter Design written by and published by . This book was released on 1982 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project gives the user of the HP-41 handheld programmable calculator a series of programs that give acceptable results during the preliminary phases of the helicopter design process. The project consists of three parts. The first part consists of several short programs and their subroutine form. These programs and subroutines compute density altitude, density, disc area, solidity, tip velocity, induced velocity, coefficient of thrust, tip loss factor, equivalent chord, and ground effect. The second part consists of major subroutines. These subroutines compute profile power, induced power, climb power, parasite power, and total power; equivalent area and induced power for a tandem rotor; and data input and change. The third part consists of the main programs. These programs compute the various power requirements for hovering flight, forward (straight and level), flight, vertical flight, and forward climbing flight; also tail rotor power, autorotative flight, and tandem rotor flight.
