An Investigation of Cross-Coupling the Elevators and Throttle Systems for the KC-135Aircraft in the Landing Configuration.

摘要

The purpose of this study was to investigate the possibility of using cross-coupling methods as additional controls during automatic landing approaches. This investigation was for aircraft that have the engine thrust line below the center of gravity of the aircraft. The KC-135aircraft dynamics were used in this study. Three methods of cross-coupling of a thrust signal into the elevator system;the cross-coupling of the glide slope beam error signal into the engine system;and a combination of these two methods. This study showed that the pitch handling characteristics of the aircraft in the landing configuration were improved with all three of the methods investigated. (Author)
