Results of an analytical investigation are presented which show the effects on low speed maneuverability of several geometric and dynamic parameters of a hybrid lighter-than-air (LTA) vehicle. Most significant of these parameters are: ratio of static lift to gross weight; relative spacing of vertical thrusters; relative amount and direction of available horizontal thrust. The analysis, which is based on nine 'points designs' representation of real vehicles, takes into account the increased moment of inertia associated with increased spacing of the dynamic thrusters.
