Available in PDF, EPUB and Kindle. Book excerpt: The hover analysis considers pilot attitude and position control tasks in the presence of horizontal gusts. The effects of each of the stability derivatives on the difficulty of the control tasks and on the closed-loop gust responses are determined. It is clearly shown that the handling qualities studies of control sensitivity and angular damping must consider the influences of M sub u (or L sub v) and should include gust inputs. These conclusions are substantiated by previous variable-stability-helicopter experiments. The effects of vehicle size and geometry are investigated by several approaches. The key result of increasing size is found to be a reduction in M sub u and L sub v which can, in turn, lower the requirements for control power and damping. The handling qualities during transition of two vehicles, a tilt duct and a tilt wing, which were previously tested on a simulator are analyzed. It is shown that both trim control and perturbations about the trim conditions must be considered. In fact, part of the increased difficulty in landing transitions, in comparison with takeoff transitions, is due to more difficult trim control; the much more stringent position control requirements in landing are also a contributing factor.

Book excerpt: Guidance and Control - II focuses on the techniques and processes involved relative to the control of rockets, missiles, and other space vehicles. Divided into seven parts with 36 chapters, the book focuses first on active and passive control for space vehicles; advances in attitude control; the stabilization of earth satellites; and the theoretical and practical considerations of solar pressure attitude control for interplanetary space vehicles. The compilation also notes the use of gyrostabilizers on satellites, including the use of two-pulse attitude control and bank angle control for an asymmetric spinning satellite. Experiments on gyro rotor imbalance on a stable platform and various navigation and guidance systems are also presented. The book also looks at the use of sensors, the stellar techniques for interplanetary flights, and control of space vehicles. The text also gives emphasis on various mathematical equations used to measure fuel optimization in orbital rendezvous. Guidance techniques in lunar landing are also discussed. The compilation is important for readers interested in studying the methods, principles, and processes involved in the control of space vehicles.

Book excerpt: Because of the 'applied' nature of ergonomics there are many outstanding pieces of work that have never been published in the archival literature. These volumes collect some of those papers that have attained classical status.

Download or read book Stability and Control of Airplanes and Helicopters written by Edward Seckel and published by Academic Press. This book was released on 2014-05-10 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stability and Control of Airplanes and Helicopters deals with aircraft flying qualities that determine the stability and control of airplanes and helicopters. It includes problems based on real aircraft, selected to represent the gamut from simple to complicated, and from conventional utility designs to futuristic research types. Many of these problems involve comparison of theory and experiment to demonstrate their mutual relationship. Comprised of 25 chapters, this book begins with a discussion on the aerodynamics of the component parts related to the lift and moment characteristics of an airplane, including wings and associated accessories; bodies such as fuselages, nacelles, and tip tanks; and control surfaces. The reader is then introduced to some mathematical techniques for linear differential equations; steady flight at different speeds; and stick force and control-free stability. Subsequent chapters focus on flaps and high-lift devices; power and compressibility effects; and the manner in which the aircraft responds to the application of control. Aeroelasticity and longitudinal equations of motion are also examined. This monograph is intended for undergraduate and graduate students taking modern engineering courses.
