Climate change summit held in Paris 2015 reaffirmed the responsibility of the nations to reduce burning of fossil fuels to arrest global warming. Aviation worldwide accounts for 3% greenhouse gas emission and being at higher altitude it is 3 times more damaging to the ozone layer. Light Weighting of Aircraft is very important to reduce the fuel consumption leading to reducing pollution. In addition, it improves fuel economy and performance. Aircraft designers use materials with higher specific strength, specific modulus and fatigue strength and such other properties to design aircraft structures with lower weight. Innovative design using innovations in engineered materials such as composites, metal honeycomb sandwich structures and manufacturing processes such as co-cure and co-bonding to reduce the number of subassemblies, reducing the number of fasteners lead to weight reduction. Innovations in miniaturization of aircraft equipments using MEMS technology, reducing weight of electric harness using innovations in materials to develop light weight cables and even reducing the weight of paints using new technologies help in reducing weight. The paper gives a step by step approach to light weighting of aircraft on the above basis. This is illustrated through case studies of India’s advanced light helicopter and light combat aircraft.
