Download or read book Flight Test Identification and Simulation of a UH-60A Helicopter and Slung Load written by and published by . This book was released on 2001 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Helicopter slung-load operations are common in both military and civil contexts. Helicopters and loads are often qualified for these operations by means of flight tests, which can be expensive and time consuming. There is significant potential to reduce such costs both through revisions in flight-test methods and by using validated simulation models. To these ends, flight tests were conducted at Moffett Field to demonstrate the identification of key dynamic parameters during flight tests (aircraft stability margins and handling-qualities parameters, and load pendulum stability), and to accumulate a data base for simulation development and validation. The test aircraft was a UH-60A Black Hawk, and the primary test load was an instrumented 8- by 6- by 6-ft cargo container. Tests were focused on the lateral and longitudinal axes, which are the axes most affected by the load pendulum modes in the frequency range of interest for handling qualities; tests were conducted at airspeeds from hover to 80 knots. Using telemetered data, the dynamic parameters were evaluated in near real time after each test airspeed and before clearing the aircraft to the next test point. These computations were completed in under 1 min. A simulation model was implemented by integrating an advanced model of the UH-60A aerodynamics, dynamic equations for the two-body slung-load system, and load static aerodynamics obtained from wind-tunnel measurements. Comparisons with flight data for the helicopter alone and with a slung load showed good overall agreement for all parameters and test points; however, unmodeled secondary dynamic losses around 2 Hz were found in the helicopter model and they resulted in conservative stability margin estimates.

Download or read book Three-dimensional, Transonic Rotor Flow Field Reconstructed from Holographic Interferogram Data written by J. K. Kittleson and published by . This book was released on 1985 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holographic interferometry and computer-assisted tomography (CAT) are used to determine the transonic flow field of a model rotor blade in hover. A pulsed ruby laser recorded 40 interferograms with a 61 cm-diam view field near the model rotor-blade tip operating at a tipo Mach number of 0.90. After digitizing the interferograms and extracting fringe-order functions, the data are transferred to a CAT code. The CAT code then calculates pressure coefficients in several planes above the blade surface. The values from the holography-CAT method compare favorably with previously obtained numerical computations and laser velocimeter measurements at most locations near the blade tip. The results demonstrate the techniques's potential for three-dimensional transonic rotor flow studies. Keywords: Holographic interferometry; Computer assisted tomography; Helicopter aerodynamics; Transonic aerodynamics.

Download or read book Patient Safety written by B.S. Dhillon and published by CRC Press. This book was released on 2011-11-08 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: With unintended harm during hospital care costing billions of dollars to the world economy, not to mention millions of deaths each year, it’s no wonder the issue is equally front and center in the minds of healthcare providers and the public. Although the issue has been tackled in journal articles and conference proceedings, there are very few books on the topic. And none consider how methods and techniques developed in the area of engineering can handle safety and human error-related problems. Until now. Written by an expert with vast know-how in engineering management, design, reliability, safety, and quality, Patient Safety: An Engineering Approach brings together the pertinent information scattered throughout books and journals, eliminating the need to consult many different and diverse sources to find what you need. B.S. Dhillon draws on his real-world experience to demonstrate how to handle patient safety-related problems using engineering techniques and backs this up with references for further reading at the end of each chapter. He sets the stage with introductory chapters on mathematical, patient safety, and human factors concepts essential to understanding materials presented in subsequent chapters. Dhillon’s clear, concise discussion of the topics presents the information in such a way that no previous knowledge is required to understand the contents, yet he does not present it at a merely rudimentary level. He brings a fresh approach and engineering perspective to the issues, giving you a new tool kit for performing patient safety-related analysis, designing better medical systems/devices, and handling patient safety-related problems from an engineering perspective.

Download or read book Helicopter Flight Dynamics written by Gareth D. Padfield and published by John Wiley & Sons. This book was released on 2018-09-07 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
