Pitch-driven ship and pitch drive propulsor Pitch-driven ship is a ship exploiting pitch energy to drive it at sufficient water heaving. Pitch-driven propulsor comprises elasto-vibrating wing that makes a propulsion generator. Said wing oscillates when ship hull pitches and is fitted on stream-lined posts-holders arranged below ship hull at preset depth. Water heaving at said depth can be considered zero, not decreasing the difference in vertical velocities of the wing and water (wing propulsion varies with square difference). To reach maximum wing propulsion, proposed propulsor is arranged nearby ship edge. Effect of separate wing increases if propulsor is mounted on every edge of the ship. Note that, in this case, propulsion and alternating acceleration are smoothed. Pitch-driven propulsor design is distinguished for by the number of posts-holders, i.e. one or two, and propulsor can be made lifting, rotary or fixed. Also there can be retractable wing extensions and wings can be made folding. Note that wing halves can vibrate independently. Proposed ship is with furnished with two pitch-driven propulsors. Flat horizontal flaps can be arranged on ship edges, nearby deadline, and screw propellers can be used in low heaving conditions. |

Set of inventions relates to sea transport facilities. The proposed sectional elastically bendable ship represents three sections elastically pivoted together so that the central cargo section "hangs" on extreme very light inertialess sections to press them in water by the springs so, that they float horizontally. With sea disturbed, the balance it is broken to the extreme sections to roll. Relative movements of heavy central section and extreme inertialess sections rolled by the waves are transformed by mechanisms of oscillating fin thrust system into moves of thrust wings of the extreme sections that makes the ship to move. The method of cargo delivery by sea is based on formation of floating train-like structure according to the design of sectional elastically bendable ship wherein the cargo can be represented by both floating objects, including towed vessels, and not floating objects, including the tanks filled by liquid products. |
