Water jet drive system with radial pumps, for fast boats

摘要

The drive unit incorporates two engines, two transmissions, and two radial pumps, and a flow directing unit. The pumps may replace a conventional propeller, and may be arranged in tandem, with each pump connected to an engine via a transmission. The velocity and pressure of the incident flow may be used to increase the output pressure, and the output flow may be directed in opposition to the direction of motion of the craft. Individual output pipes may also be used in order to facilitate forwards, backwards, and sideways motion.
