Turbines
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.

Shakedown Cruise
Shakedown cruise is a nautical term in which the performance of a ship is tested. Generally, shakedown cruises are performed before a ship enters service or after major changes such as a crew change, repair, refit or overhaul. The shakedown cruise simulates working conditions for the vessel, for various reasons. For most new ships, the major reasons are to familiarise a crew with a new vessel and to ensure all of the ship's systems are functional. Overview If the ship is the first of its class, it will likely also be performing its sea trials, a test of its performance. In this context, 'shakedown cruise' and 'sea trials' may be used interchangeably, though each has a slightly different meaning. In such a case, it is likely that the ship's systems will be pushed to redline, or maximum capacity, to demonstrate the class's speed and other important traits. Until bested by another ship of the same class, this shakedown performance will be the standard of the class's capabiliti ...
