Abstract
An elongated fluid dynamic water jet type of propulsion body receives an inflow of fluid through inlet openings for entry into a jet propulsor from which an outlet jet emerges for passage through an internal transition passage to an exit end between two pairs of horizontal flaps hinged to the body at the exit end for angular displacement about parallel spaced horizontal axes from horizontal neutral positions. Four pair of flaps are pivotally mounted within the transition passage for angular displacement about parallel spaced vertical axes from neutral positions. Actuators inside of the propulsion body connected to the flaps are selectively controlled to impart in-phase angular displacement to all of the flaps about their horizontal and vertical axes from the neutral positions for directional steering by angular deflection of the jet exit outflow from the exit end of the body. To reverse propulsion, only the actuators for the horizontal flaps are activated in an out-of-phase mode to effect angular displacement of each pair of the horizontal flaps in opposite directions into engagement with each other thereby blocking jet outflow from the exit end of the body causing a directional re…
