The gas turbine operates like a jet engine but drives a generator instead of fan blades.

Problems with engine turbine blades wearing out sooner than expected have hampered a restructuring programme prompted by the engineering company's declining older engine programmes and plunging demand for oil equipment.

The technology overlaps are valuable: For example, carbon - fiber - reinforced composites developed for jet - engine fan blades are used in GE's wind - turbine fan blades, and ceramics developed for electricity - generating turbines are used in jet engines.

The aerodynamics of the turbine blades affects the efficiency of the engine, while the heat transfer from the extremely hot gas to the turbine blades is harmful to the life - span of the turbine.

When evaluating a part, such as a turbine blade inside a hot jet engine, it is important to know how each segment of the blade heats up as hot gases flow around it.

Camci, who has worked on the method since 1989 with Steve Hippensteele of NASA's Lewis Research Center in Cleveland, Ohio, says that liquid crystals have several advantages: «The crystals are available as sheets of Mylar (polyethylene terephthalate) plastic or in liquid form, so that covering an entire piece of equipment, such a s a turbine blade or a jet engine duct, is fairly simple, particularly compared to applying thermocouples.

«I have never seen ash actually melting on a turbine blade or other hot engine part before,» he says.
