This book was released on 1967 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the feasibility of a self-learning adaptive system for the flight control of high performance aircraft has been performed. A flight control system was developed for the investigation of the stability augmentation of the longitudinal axis of the F101B aircraft using self-learning adaptive control. The learning adaptive controller developed employs a three-loop concept. The innermost loop comprises a linear feedback control system in which a set of control gains is adjusted by a second (adaptive) loop employing a parameter identifier and a trainable function generator (automation). The automation provides the correct values of feedback gain in response to patterns derived from the identified aircraft parameters. The third loop (the learning loop) measures control system performance, and continually retrains the automation to improve the performance. Experiments were performed with a digital simulation of the aircraft and the learning adaptive control system. Results of the experiments indicate that learning adaptive control is feasible. However, a number of significant technical problems must be overcome prior to the use of such a control system in tactical aircraft. Studies of sensitivity must be performed to assess the effect of small perturbations in the identification parameters on system performance. Extended studies of property extraction from the identified parameters is required, and means for further simplifying the control structure is of importance in a real system. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The history of flight control is inseparably linked to the history of aviation itself. Since the early days, the concept of automatic flight control systems has evolved from mechanical control systems to highly advanced automatic fly-by-wire flight control systems which can be found nowadays in military jets and civil airliners. Even today, many research efforts are made for the further development of these flight control systems in various aspects. Recent new developments in this field focus on a wealth of different aspects. This book focuses on a selection of key research areas, such as inertial navigation, control of unmanned aircraft and helicopters, trajectory control of an unmanned space re-entry vehicle, aeroservoelastic control, adaptive flight control, and fault tolerant flight control. This book consists of two major sections. The first section focuses on a literature review and some recent theoretical developments in flight control systems. The second section discusses some concepts of adaptive and fault-tolerant flight control systems. Each technique discussed in this book is illustrated by a relevant example.

Available in PDF, EPUB and Kindle. Book excerpt: Includes the proceedings from the 7th IAASS Conference, "Space Safety is No Accident," held in Friedrichshafen, Germany, in October 2014. The 7th IAASS Conference, “Space Safety is No Accident” is an invitation to reflect and exchange information on a number of topics in space safety and sustainability of national and international interest. The conference is also a forum to promote mutual understanding, trust and the widest possible international cooperation in such matters. The once exclusive “club” of nations with autonomous sub-orbital and orbital space access capabilities is becoming crowded with fresh and ambitious new entrants. New commercial spaceports are starting operations and others are being built. In the manned spaceflight arena a commercial market is becoming a tangible reality with suborbital spaceflights and government use of commercial services for cargo and crew transportation to orbit. Besides the national ambitions in space, the international cooperation both civil and commercial is also gaining momentum. In the meantime robotic space exploration will accelerate and with it the need to internationally better regulate the usage of nuclear power sources. Space-bound systems and aviation traffic will share more and more a crowded airspace, while aviation will increasingly rely on space-based safety-critical services. Finally, most nations own nowadays space assets, mainly satellites of various kinds and purposes, which are under the constant threat of collision with other spacecraft and with the ever increasing number of space debris. Awareness is increasing internationally (as solemnly declared since decades in space treaties) that space is a mankind asset and that we all have the duty of caring for it. Without proactive and courageous international initiatives to organize space, we risk to negate access and use of space to future generations.

Available in PDF, EPUB and Kindle. Book excerpt: The title of the book, Walk This Way, was taken from a joke that Ray and his good friend, Boris Boskovich, used to tell each other over and over again as they traveled together on Honeywell business. The punch line of the joke has the guy saying to the nurse, "If I could walk that way, I wouldn't need the talcum powder." The title also is a double entendre referring to the advice given in the various opinions the author presents, which he believes can lead to a healthier and more productive life.

This book was released on 1963 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: To establish the differences between self-adap tive and normal linear designs, both systems are applied to the problem of controlling the short period dynamics of the X-15. The self-adaptive system studied is an early design of the MH-96 Autopilot. The high-gain-linear system is de signed on the basis of selecting the forward branch compensation so that the system is in sensitive to vehicle-parameter variations over the bandwidth of the desired response and a pre filter or feedback-branch compensation is used to obtain the desired command response. The root-locus method is used in the initial design of the system; but, the system could not be simu lated on the analog computer. The frequency response method was used for the design of a second system. From this linear analysis of design procedures and response data, it is con cluded that the high-gain-linear system is pre ferred to a self-adaptive system; however, an analysis of the effects of system non-linearities and component noise must be made before a fixed gain system can be applied to the physical prob lem of widely varying vehicle parameters.

Download or read book F-8C Adaptive Flight Control Laws written by G. L. Hartmann and published by . This book was released on 1977 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three candidate digital adaptive control laws were designed for NASA's F-8C digital flyby wire aircraft. Each design used the same control laws but adjusted the gains with a different adaptative algorithm. The three adaptive concepts were: high-gain limit cycle, Liapunov-stable model tracking, and maximum likelihood estimation. Sensors were restricted to conventional inertial instruments (rate gyros and accelerometers) without use of air-data measurements. Performance, growth potential, and computer requirements were used as criteria for selecting the most promising of these candidates for further refinement. The maximum likelihood concept was selected primarily because it offers the greatest potential for identifying several aircraft parameters and hence for improved control performance in future aircraft application. In terms of identification and gain adjustment accuracy, the MLE design is slightly superior to the other two, but this has no significant effects on the control performance achievable with the F-8C aircraft. The maximum likelihood design is recommended for flight test, and several refinements to that design are proposed.
