Turbines

Now in Turbines

Uriah Boyden

Uriah Boyden turned around how we harness the power of water by reversing the waterwheel concept of rotation through water filling—now turbines rotated as the falling water was conducted into them, striking the metal veins that spiraled around a central shaft.

Turbines and Ash Clouds: Asking for Trouble?

Passengers may think worldwide flight cancellations and reroutings were unnecessary after Iceland’s Eyjafjallajökull’s recent eruption, but clouds of volcanic ash and dust pose real and substantial dangers for aircraft jet engines. Flying through ash clouds can cause millions of dollars worth of damage to the engines—or even shut them down entirely.

Turbine Fuel Efficiency: Fitting a Pitch

A new variable pitched turbofan design that could consume as much as 14% less fuel relative to today’s fans is generating excitement in the airline industry, where a few percentage points of increase in fuel efficiency can be the difference between profit and bankruptcy for an airline. Rotating Composite Technologies has come out with a unique patented design and is now working with jet engine companies to develop and test it.

Turbines are rotating machinery for extracting mechanical or electrical energy from steam, from burning natural gas and oil, and from moving water including tides and hydroelectric dams. Biggest turbine uses are in generating electricity, powering aircraft, driving the propellers of nearly all large seagoing vessels. Turbine rotor and stator blades (airfoils), disks, and seals place severe demands on the science of high-temperature materials, on component manufacturing and on quality assurance.
