This invention relates to the use of a venting assembly for sails, comprising one or more aperture substantially perpendicular with the sail surface separating a fore and aft element of the sail. The aperture channels high energy air flow from the windward side of the sail through to the leeward side of the sail parallel to the sail surface, energizing the surface boundary layer and maintaining laminar air flow along the aft element of the sail.

This invention relates to the use of a removably attachable sailing rig with an integrated water foil for the conversion of a conventional boat, row boat, kayak, canoe, and power boat into a sailboat or an existing sailboat rig into a canting sail rig. The sail rig system utilizes the strong attachment points inherently available on most conventional boats and soft inflatable boats for attachment. The sail rig is comprised of a mast with an integrated water foil and is supported by a rigid strut on each side forming a tripod with the mast, a sail is attached to the mast which is unconventionally tacked or jibed around the front of the mast in order to clear the struts. The base of each rigid strut has a strut attachment means for direct attachment to an oar lock or shear of a boat. The base of the mast has a bow attachment means for direct attachment to the bow or bow towing ring. The mast and water foil can be tilted or canted to either side of the boat by lengthening or shortening each rigid strut. The sail rig system also has a separate rudder for steering.
摘要:
A detachable planing enhancement system with two substantial planing surface areas attached symmetrically on the transom of an inflatable sportboat to provide a substantial lifting force thereon. The system includes a method of quick attachment and detachment to the transom of the inflatable sportboat and means to ventilate such planing surfaces with air to reduce drag at high planing speeds. The planing surfaces and attachment components are comprised of plastic compatible with the injection molding process of fabrication.

A ballast container attached to the outside of a sailboat for holding controlled quantity of water as ballast to provide a controllable stabilizing force thereon. The container includes a method of attachment to the windward rail of the sailboat and a means of filling and draining controlled quantities of water. The container is formed of foldable water tight material that fills to shape when receiving and holding water and collapses for stowage on and off the beam rail when not in use.

This invention relates to a universally attachable hinged wing that pivots and provides lift for multirotor drones while moving in a forward direction of flight, thus reducing power consumption and increasing payload capacity or flight duration time and distance, and provides a visual line of sight (VLOS) aid while hovering.

This invention relates to the use of an automatic safety parachute deployment system for drones (UAVs), which utilizes an airflow trigger that deploys one or more parachutes under certain aerodynamic conditions from the upward airflow during a flight malfunction. The system is mechanically activated without the use of electronics, batteries or an ejection spring which reduces the complexity and weight.
