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.

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.

Download or read book The Foundations of Helicopter Flight written by Simon Newman and published by John Wiley & Sons. This book was released on 1994 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The helicopter is a sophisticated aircraft and is therefore demanding on its designers. This unique introductory text charts a journey through the theory, design, construction and operation of helicopters. The difficulties that can arise when the aircraft is considered as a whole are highlighted using many practical examples and case studies. The author examines these problems for situations in which the helicopter is operating on the ground or in flight. The book provides in-depth support for any first course in helicopter engineering. It introduces the principles of rotary wing flight and develops the fundamental equations describing the performance and dynamic behaviour. Essential theories are developed and applied to show how the capabilities and behaviour of a helicopter are influenced by the manner in which rotor characteristics interact with those of the airframe. The author’s broad experience as a design engineer and lecturer combine to produce a book for students, graduates and professionals that conveys not only the essential information but also a real enthusiasm for the subject.

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.

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.

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.
