The thesis proposes a free-fall, hydrodynamically tuned, lifting sensor containing two accelerometers to record a velocity profile in the deep ocean. A free fall device frees the mother ship for other oceanographic work while the sensor is collecting information. Hydrodynamic tuning eliminates the need for a vehicle guidance system with adjustable wings. The major work of this thesis centered about obtaining the hydrodynamic stability derivatives through the use of a planar-motion-mechanism. The derivatives are used to determine the external wing configuration and position for a suitable instrument carrying vehicle. The linear response of the proposed sensor vehicle to a disturbance velocity was obtained by means of an analog computer solution of the linearized equations of motion. Author
