Propeller

A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Propeller dynamics, like those of aircraft wings, can be modelled by either or both Bernoulli's principle and Newton's third law. A marine propeller of this type is sometimes colloquially known as a screw propeller or screw, however there is a different class of propellers known as cycloidal propellers - they are characterized by the higher propulsive efficiency averaging 0.72 compared to the screw propellers average of 0.6 and the ability to throw thrust in any direction at any time. Their disadvantages are higher mechanical complexity and higher cost.

History

Early developments

The principle employed in using a screw propeller is used in sculling. It is part of the skill of propelling a Venetian gondola but was used in a less refined way in other parts of Europe and probably elsewhere. For example, propelling a canoe with a single paddle using a "pitch stroke" or side slipping a canoe with a "scull" involves a similar technique. In China, sculling, called "lu", was also used by the 3rd century AD.

Propeller (Peter Stuart album)

Propeller is a 2002 studio album from the American singer-songwriter Peter Stuart. The album marked Stuart's solo debut. Stuart had previously formed the rock band Dog's Eye View in 1994. Before their hiatus, Stuart had been Dog's Eye View's lead vocalist and songwriter.

The album's lead single was "With My Heart in Your Hands".

Background

Dog's Eye View founder and vocalist Peter Stuart had left the band to pursue solo projects following their 1997 release, Daisy. Stuart, who had been a solo performer prior to forming Dog's Eye View, has stated that the idea of his making a solo album originally came from the group's record label, Columbia Records:

His first solo album was originally slated to be called Songs About You. Stuart began recording the album for Columbia, which had released the first two Dog's Eye View albums, Happy Nowhere and Daisy. Early production and recording were completed in Los Angeles. However, Stuart soon became disenchanted with Columbia executives, citing a lack of support for the album and other creative differences. He voluntarily severed ties with Columbia, and left the label with the rights to his forthcoming solo album.

Rame

"Rame" is a rare word in English which means branch. Rame is also the name of two villages in Cornwall:

Rame may also refer to:

Rame, Maker-with-Rame

Coordinates: 50°19′29″N 4°12′48″W / 50.3246°N 4.2133°W / 50.3246; -4.2133

Rame (Cornish: Hordh) is a hamlet between Rame Head and the village of Cawsand in South East Cornwall. It is situated on the Rame Peninsula. Rame means the high protruding cliff, or possibly, the ram's head.

Originally Cawsand was in the parish of Rame, but now has its own church in the village. The neighbouring church at Maker is in the same parish as Rame. Together they are called 'Maker-with-Rame' parish. Rame was recorded in the Domesday Book (1086) when it was held by Ermenhald from Tavistock Abbey. There were 27 households, land for 6 ploughs, 10 acres of pasture and 30 acres of underwood. An electoral ward bearing the name of Rame exists. The population at the 2011 census was 4,763.

There is another Rame near Falmouth in west Cornwall. It is believed that the west Cornwall Rame was named after the one on the Rame Peninsula.

During his time in command of the Channel Fleet between 1805 and 1807 John Jervis, 1st Earl of St Vincent rented a house in Rame.
