ABSTRACT: In the aerospace industry, there is a great need for new materials which exhibit improved mechanical properties. Materials possessing high strength at a reduced mass and size make lighter aircraft with lower fuel consumption. The development of new materials with tailored properties is a primary goal of today’s materials science and engineering. This paper gives us a brief idea of the various applications and benefits of nanotechnology in Aerospace Industries.

I. Introduction
The global passenger traffic is expected to increase steadily over the next 20 years by an average growth rate of about 5%. Main reasons are GDP growth, increased globalization, and population growth. To satisfy these expectations aircraft companies are looking for new technologies. They are looking for increased safety, reduced emissions, reduced noise, increased capacity, increased range, enhanced payload, higher speed, lower operating and maintenance costs, better overall management of the aircraft and its use.
II. Properties Of Nanomaterials
The main driving force towards lighter materials is the fact that transport costs decrease by a factor of $300 per pound of reduced weight in commercial aircraft transport. This value is 100 times as high as it is in the automotive sector. Reduced weight leads to lower costs and better ecological compatibility due to reduced fuel consumption
The most important properties addressed by aerospace materials are strength, stiffness, impact resistance, long lifetime, toughness, ductility and lightness. Revolutionary new Nano composites have the promise to be 100 times
