Book excerpt: With the advent of digital engine control systems, considering the use of engine thrust for emergency flight control has become feasible. Many incidents have occurred in which engine thrust supplemented or replaced normal aircraft flight controls. In most of these cases, a crash has resulted, and more than 1100 lives have been lost. The NASA Dryden Flight Research Center has developed a propulsion-controlled aircraft (PCA) system in which computer-controlled engine thrust provides emergency flight control capability. Using this PCA system, an F-15 and an MD-11 airplane have been landed without using any flight controls. In simulations, C-17, B-757, and B-747 PCA systems have also been evaluated successfully. These tests used full-authority digital electronic control systems on the engines. Developing simpler PCA systems that can operate without full-authority engine control, thus allowing PCA technology to be installed on less capable airplanes or at lower cost, is also a desire. Studies have examined simplified ?PCA Ultralite? concepts in which thrust control is provided using an autothrottle system supplemented by manual differential throttle control. Some of these concepts have worked well. The PCA Ultralite study results are presented for simulation tests of MD-11, B-757, C-17, and B-747 aircraft.Burcham, Frank W., Jr. and Kaneshige, John and Bull, John and Maine, Trindel A.Ames Research Center; Armstrong Flight Research CenterFLIGHT CONTROL; SIMULATORS; TRANSPORT AIRCRAFT; DIGITAL SYSTEMS; ENGINE CONTROL; THRUST CONTROL; BOEING 747 AIRCRAFT; BOEING 757 AIRCRAFT; MD 11 AIRCRAFT; C-17 AIRCRAFT; F-15 AIRCRAFT; COST REDUCTION

This book was released on 2018-07-17 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A propulsion-controlled aircraft (PCA) system for emergency flight control of aircraft with no flight controls was developed and flight tested on an F-15 aircraft at the NASA Dryden Flight Research Center. The airplane has been flown in a throttles-only manual mode and with an augmented system called PCA in which pilot thumbwheel commands and aircraft feedback parameters were used to drive the throttles. Results from a 36-flight evaluation showed that the PCA system can be used to safety land an airplane that has suffered a major flight control system failure. The PCA system was used to recover from a severe upset condition, descend, and land. Guest pilots have also evaluated the PCA system. This paper describes the principles of throttles-only flight control; a history of loss-of-control accidents; a description of the F-15 aircraft; the PCA system operation, simulation, and flight testing; and the pilot comments.

Book Synopsis Writing Human Factors Research Papers by : Don Harris
Download or read book Writing Human Factors Research Papers written by Don Harris and published by CRC Press. This book was released on 2016-12-05 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Writing high-quality papers suitable for publication within international scientific journals is now an essential skill for all early-career researchers; their career progression and the reputation of the department in which they work depends upon it. However, many manuscripts are rejected or sent back for major re-working not because the science they contain is in any way 'bad', but because the same problems keep occurring in the way that the material is presented. It is one thing to write a good scientific paper, however it is quite another thing to get it published. This requires some additional nous. In writing this book Don Harris draws upon nearly a quarter of a century of experience as an author and reviewer of research papers, and ultimately as a journal editor. By his own admission, it contains all the things he wished that his mentors had told him 25 years ago, but didn't. The material in the book is drawn from many years of finding all these things out for himself, usually by trial and error (but mostly error!). The text adopts a much lighter touch than is normally found in books of this type - after all, who really wants to read a book about writing research papers? The author describes his own unique approach to writing journal papers (which, in his own words, has proved to be extremely successful). All major points are illustrated with examples from his own, published works. The book is written in the form of a manual for constructing a journal manuscript: read a chapter, write a section. However, the material it contains goes beyond just this and also describes how to select a target journal, the manuscript submission process, what referees are looking for in a good journal paper, and how to deal with the referees' comments. Each chapter concludes with a checklist to ensure all the key elements have been addressed.
Book Synopsis Fault Detection and Fault-Tolerant Control Using Sliding Modes by : Halim Alwi
Download or read book Fault Detection and Fault-Tolerant Control Using Sliding Modes written by Halim Alwi and published by Springer Science & Business Media. This book was released on 2011-06-07 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fault Detection and Fault-tolerant Control Using Sliding Modes is the first text dedicated to showing the latest developments in the use of sliding-mode concepts for fault detection and isolation (FDI) and fault-tolerant control in dynamical engineering systems. It begins with an introduction to the basic concepts of sliding modes to provide a background to the field. This is followed by chapters that describe the use and design of sliding-mode observers for FDI using robust fault reconstruction. The development of a class of sliding-mode observers is described from first principles through to the latest schemes that circumvent minimum-phase and relative-degree conditions. Recent developments have shown that the field of fault tolerant control is a natural application of the well-known robustness properties of sliding-mode control. A family of sliding-mode control designs incorporating control allocation, which can deal with actuator failures directly by exploiting redundancy, is presented. Various realistic case studies, specifically highlighting aircraft systems and including results from the implementation of these designs on a motion flight simulator, are described. A reference and guide for researchers in fault detection and fault-tolerant control, this book will also be of interest to graduate students working with nonlinear systems and with sliding modes in particular. Advances in Industrial Control aims to report and encourage the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.

This book was released on 2018-10-25 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Failures of aircraft primary flight-control systems to aircraft during flight have led to catastrophic accidents with subsequent loss of lives (e.g., DC-1O crash, B-747 crash, C-5 crash, B-52 crash, and others). Dryden Flight Research Center (DFRC) investigated the use of engine thrust for emergency flight control of several airplanes, including the B-720, Lear 24, F-15, C-402, and B-747. A series of three piloted simulation tests have been conducted at Ames Research Center to investigate propulsion control for safely landing a medium size jet transport which has experienced a total primary flight-control failure. The first series of tests was completed in July 1992 and defined the best interface for the pilot commands to drive the engines. The second series of tests was completed in August 1994 and investigated propulsion controlled aircraft (PCA) display requirements and various command modes. The third series of tests was completed in May 1995 and investigated PCA full-flight envelope capabilities. This report describes the concept of a PCA, discusses pilot controls, displays, and procedures; and presents the results of piloted simulation evaluations of the concept by a cross-section of air transport pilots.

Available in PDF, EPUB and Kindle. Book excerpt: With modern digital control systems, using engine thrust for emergency flight control to supplement or replace failed aircraft normal flight controls has become a practical consideration. The NASA Dryden Flight Research Center has developed a propulsion-controlled aircraft (PCA) system in which computer-controlled engine thrust provides emergency flight control. An F-15 and an MD-11 airplane have been landed without using any flight control surfaces. Preliminary studies have also been conducted that show that engines on only one wing can provide some flight control capability if the lateral center of gravity can be shifted toward the side of the airplane that has the operating engine(s). Simulator tests of several airplanes with no flight control surfaces operating and all engines out on the left wing have all shown positive control capability within the available range of lateral center-of-gravity offset. Propulsion-controlled aircraft systems that can operate without modifications to engine control systems, thus allowing PCA technology to be installed on less capable airplanes or at low cost, are also desirable. Further studies have examined simplified "PCA Lite" and "PCA Ultralite" concepts in which thrust control is provided by existing systems such as autothrottles or a combination of existing systems and manual pilot control.

This book was released on 2018-11-07 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: An emergency flight control system that uses only engine thrust, called the propulsion-controlled aircraft (PCA) system, was developed and flight tested on an MD-11 airplane. The PCA system is a thrust-only control system, which augments pilot flightpath and track commands with aircraft feedback parameters to control engine thrust. The PCA system was implemented on the MD-11 airplane using only software modifications to existing computers. Results of a 25-hr flight test show that the PCA system can be used to fly to an airport and safely land a transport airplane with an inoperative flight control system. In up-and-away operation, the PCA system served as an acceptable autopilot capable of extended flight over a range of speeds, altitudes, and configurations. PCA approaches, go-arounds, and three landings without the use of any normal flight controls were demonstrated, including ILS-coupled hands-off landings. PCA operation was used to recover from an upset condition. The PCA system was also tested at altitude with all three hydraulic systems turned off. This paper reviews the principles of throttles-only flight control, a history of accidents or incidents in which some or all flight controls were lost, the MD-11 airplane and its systems, PCA system development, operation, flight testing, and pilot comments.
