Hovering Flight Investigation Of Two Methods Of Controlling A Man Carrying Ducted Fan Vehicle Of The Flying Platform Type PDF Download

Tests were performed during which men of widely varying previous flight experience served as pilots of a 4-ft-diameter vehicle, controlling it either kinesthetically or by a system of air jets actuated by an airplane-type control stick. All the men could control the vehicle satisfactorily with either system although some practice time was occasionally required by some men for one system or the other. Flights were generally smoother with the stick control system, which was preferred over the kinesthetic method by most of the men. (Author).
