Download or read book A Theoretical Method of Determining the Control Gearing and Time Lag Necessary for a Specified Damping of an Aircraft Equipped with a Constant-time-lag Autopilot written by Ordway B. Gates and published by . This book was released on 1951 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is presented for determining the control gearing and time lag necessary for determining a specified damping of the motions of an aircraft equipped with an autopilot having a constant-time-lag characteristics. The method is applied to a typical present-day airplane equipped with an autopilot sensitive to yawing acceleration. The types of motion predicted for this airplane-autopilot system by this method are compared with motions calculated by a step-by-step procedure.
