This construction is called "The Saye's Rigg". Another version of wind vane self steering on sail boats is known as the vertical axis vane and usually, because of the inferior steering force output compared to servo pendulum devices it makes use of a trim tab hung off the rudder to control the course of the boat. The vane spins at right angles ...
The first was when part of the frame holding the wind vane self-steering failed, when still 2,300 miles (3,700 km) from Sydney. Not wanting to put in at Fremantle, Western Australia , Chichester spent three days balancing sails and experimenting with shock-cord lines on the tiller, once again getting the boat to hold a course to enable her to ...
The boat also housed a Hasler self-steering system with a wind vane and servo blade as well as a Hengist-Horsa wind speed and direction indicator. Below deck the built-out consisted of a built-in writing and eating table with a small red cushioned seat that would have hidden the ‘main computer’ but instead obscured a tangle of carefully ...
The Keying was a Chinese ship that employed a junk sailing rig. Scale model of a Tagalog outrigger ship with junk sails from Manila, 19th century. The junk rig, also known as the Chinese lugsail, Chinese balanced lug sail, or sampan rig, is a type of sail rig in which rigid members, called battens, span the full width of the sail and extend the sail forward of the mast.
In the event of skew winds the "wind pressure" on the swept area causes a yawing moment around the tower axis (z-axis) which orients the rotor. [1] The tail fin (or wind vane) is commonly used for small wind turbines since it offers a low cost and reliable solution. It is however unable to cope with the high moments required to yaw the nacelle ...
A man who was “worried” about his fiancée coming home unusually late after work — notably, at 4 a.m. — is wondering if he’s “out of line” for asking her to let him know in the ...
U.S. President Donald Trump's return to the White House has been met with both relief and disappointment across world markets as investors try to work out what the next four years will bring. "The ...
B-1B Lancer showing left hand ride-control vane at nose. The Rockwell B-1 Lancer has small canard vanes or fins on either side of the forward fuselage that form part of an active damping system that reduces aerodynamic buffeting during high-speed, low altitude flight. Such buffeting would otherwise cause crew fatigue and reduce airframe life ...
