Book excerpt: An H-21D helicopter with the Vertol stability augmentation system (SAS) and differential-deltathree was evaluated. The differential-deltathree was found to provide acceptable longitudinal dynamic stability and allow hands-off flight (longitudinally) for periods of up to 1 minute. The longitudinal channel of the SAS also provided positive longitudinal stability and allowed hands-off flight for periods of at least 1 minute. With the SAS operating, the response to a longitudinal disturbance was (jerky) and was considered objectionable in rough air. It must be noted that the differential-delta-three was operating at all times and therefore a double correction for longitudinal disturbances was present with the SAS operating. The lateral stability provided by the SAS was considered excellent. However, the reduction in lateral control response and the nature of the response (a 1 inch step input results in a fixed bank angle and does not maintain a roll rate) with SAS operating were objectionable. The SAS did not improve directional flying qualities, and some loss of directional control response was noted in hover. (Author).

Download or read book The Navy Times Book of Submarines written by Brayton Harris and published by Berkley Hardcover. This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shattering long-held myths and misunderstandings, author Brayton Harris traces the development of the submarine through an era in which writers of fiction saw the merits better than most professionals -- until the Germans almost won World War I. He covers the professional and political arrogance that delayed antisubmarine development for so long that German submarines almost won World War II as well, and examines post-war progress toward the truly awesome submarine of today. Along the way, Harris explores the shifting moral issues of "unrestricted" naval warfare, outlines the hundred-year search for an effective underwater power plant that culminated in the nuclear reactor, and raises important questions about the future. A fascinating exploration of the steps and stumbles during development, a rousing tribute to those who fought and died, and a powerful study of the submarine's impact on America, The Navy Times Book of Submarines is an unparalleled source for understanding the great "hunters of the deep".
