Abstract
The primary objective of the study was accomplished by reducing vehicle bending moment due to the design wind disturbance by at least 20 percent with three different types of linear feedback control loops. The secondary objective was accomplished with one of the three bending moment reduction systems. Each of the feedback loops developed was used in parallel with the existing attitude control feedback loops. In addition to the three linear systems devised, a non-linear controlling device was found to reduce transient peaks in bending moment due to gusts. This gust relief system was found to reduce bending moment peaks by six percent of the total bending moment.
