Aircraft turbine blades and expected advancement in technology using carbon nanotubes

Gas turbines are of prime importance to aircrafts. The turbo machinery is a complex aspect of designing. Efficiency of turbo machinery is closely proportional to material selection and its performance. Each section of a turbo machinery deserves or has a different criteria of temperature dependency. As per this dependency turbine blades, nozzles and wheels are designed using different types of materials- alloys, which are highly resistant to temperature and light weight. This will lead to aircrafts which are very light and highly efficient. These materials are alloys which are very costly. And this high cost are making them difficult to be used abundantly. All these problems has made researchers to look around for material which is light, comparatively cheap and highly efficient as per turbine needs. This paper throws light on the existing materials used in turbine blades and a new compound which is a carbon allotrope which is capable of meeting all above needs perfectly.
