Abrégé

The drag sail has multiple ropes (2) for attaching to a ship (3). A profiled plastic structure in wave form or zigzag is formed by transverse ribs (4). The transverse ribs run together transverse to the wind direction at a distance and exhibit any form e.g. circular, semicircular or square, in shape. The transverse ribs receive the ropes at its end points, and additional ropes (2A) in a middle region. The drag sail is made of plastic or cloth.

Abrégé

This specification describes a system for deploying a series array of tethered aerofoils such that individual aerofoils can be deployed and retracted as required. This is intended to enable the handling of very large aerofoils and large arrays so that wind power can be deployed at a scale not previously possible. The system is particularly intended for propelling vessels at sea. The system uses an auxiliary aerofoil to raise primary tethers into the air, thus establishing a primary array structure to which duty aerofoils can be added, using controllable runners, to provide the main source of aerodynamic power. Duty aerofoils can be deployed in any desired configuration and recovered singularly without retracting the whole array.

Abrégé

This specification defines a system which receives and passively manages the incident force vectors arising from at least one tethered aerofoil and from one or more other sources so as to minimise the torque exerted on the structural body of a craft by these forces to substantially zero in the roll, pitch and, in some embodiments, yaw axes, while transmitting the forces to the structural body in three dimensions. This imposed-torque-minimising system allows a high-powered propulsion system based upon tethered aerofoils to propel a relatively small craft without forcibly tilting it to port, to starboard, forward or aft, which is an important prerequisite for safe, controllable operation of such craft in most cases.
