Curtis turbine
Turbine Tur"bine, n. A form of steam engine analogous in construction and action to the water turbine. There are practically only two distinct kinds, and they are typified in the de Laval and the Parsons and Curtis turbines. The de Laval turbine is an impulse turbine, in which steam impinges upon revolving blades from a flared nozzle. The flare of the nozzle causes expansion of the steam, and hence changes its pressure energy into kinetic energy. An enormous velocity (30,000 revolutions per minute in the 5 H. P. size) is requisite for high efficiency, and the machine has therefore to be geared down to be of practical use. Some recent development of this type include turbines formed of several de Laval elements compounded as in the ordinary expansion engine. The Parsons turbine is an impulse-and-reaction turbine, usually of the axial type. The steam is constrained to pass successively through alternate rows of fixed and moving blades, being expanded down to a condenser pressure of about 1 lb. per square inch absolute. The Curtis turbine is somewhat simpler than the Parsons, and consists of elements each of which has at least two rows of moving blades and one row of stationary. The bucket velocity is lowered by fractional velocity reduction. Both the Parsons and Curtis turbines are suitable for driving dynamos and steamships directly. In efficiency, lightness, and bulk for a given power, they compare favorably with reciprocating engines.

Turbine
Turbine Tur"bine, n. [L. turbo, -inis, that which spins or whirls round, whirl.] A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc.; -- also called turbine wheel. Note: In some turbines, the water is supplied to the wheel from below, instead of above. Turbines in which the water flows in a direction parallel to the axis are called parallel-flow turbines.
turbine wheel
Water wheel Wa"ter wheel` 1. Any wheel for propelling machinery or for other purposes, that is made to rotate by the direct action of water; -- called an overshot wheel when the water is applied at the top, an undershot wheel when at the bottom, a breast wheel when at an intermediate point; other forms are called reaction wheel, vortex wheel, turbine wheel, etc. 2. The paddle wheel of a steam vessel. 3. A wheel for raising water; a noria, or the like.

Turbinella
Turbinella Tur`bi*nel"la, n. [NL., dim. fr. L. turbo, -inis, a top.] (Zo["o]l.) A genus of large marine gastropods having a thick heavy shell with conspicuous folds on the columella.
Turbinella pyrum
Sankha Sank"ha, n. [Skr. [,c]ankha a shell.] A chank shell (Turbinella pyrum); also, a shell bracelet or necklace made in India from the chank shell.
Turbinella pyrum
Chank Chank", n. [Skr. [,c]a[.n]kha. See Conch.] (Zo["o]l.) The East Indian name for the large spiral shell of several species of sea conch much used in making bangles, esp. Turbinella pyrum. Called also chank chell.
Turbinella rapha
Papboat Pap"boat`, n. 1. A kind of sauce boat or dish. 2. (Zo["o]l.) A large spiral East Indian marine shell (Turbinella rapha); -- so called because used by native priests to hold the oil for anointing.
