NANOTECHNOLOGY IN AVIATION Israel Stephen U. Manigandan D. III Yr, Aeronautical Excel College Of Engg. & Tech 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.

• Visionary ideas include fault tolerant and self-healing materials. It has been shown that nanoparticles dispersed throughout a material can migrate to cracks, potentially giving rise to self-healing composites (if sufficient migration occurs to seal cracks). For example experiments have been undertaken with spherical particles of about five nanometers underneath silicon oxide. With the right coating, the nanoparticles automatically migrate toward cracks in the silicon oxide. • Aircraft safety and security is also being increased through the use of new materials in the interior. One example is the development of bullet proof materials for sensitive parts, e. g. the cockpit door. High strength and lightweight composite laminates (incorporating carbon nanotubes in a variety of resins) are being investigated for use in ballistic protection and novel damping materials. • An important aspect for the interior of an aircraft is the need for fire retardant materials. The aim is to meet the stringent specifications demanded of materials used in aircraft interiors more cheaply and effectively than with the costly specialized polymers currently used. It has been shown that the introduction of nanoparticle additives to 5 % can lead to a huge reduction in fire risk. On the other hand nanoparticles can also act as fire accelerant. • The Boeing 787 concept not
