The trajectory characteristics of the selected Galileo orbital tour for the May 1986 launch opportunity are presented, and the interplay between tour design and science requirements is discussed. The orbital tour design concepts are summarized, and the research objectives in the areas of magnetospheric science, satellite imaging, observations of the Jupiter atmosphere, and radio science are discussed. Each of the encounter with the moons of Jupiter that would have occurred if the launch opportunity had been utilized are described, giving the dates of the planned encounters. Trajectory pole views and earth views of occultations during encounters are diagrammed.
A review of major ride-quality criteria used in the design of commercial helicopters, some of the limitations of these criteria, research programs conducted to better define these criteria, and some recommended research programs is presented. Primary emphasis is given to the question of noise and vibration criteria for passenger acceptance and comfort.
