Abstract: From post twentieth century use of aluminium alloys increases drastically in automobile and aerospace industries. The aluminium alloy takes the advantage of "strength to weight ratio‟ and corrosion properties over other structural element such as steel and its alloys. The altered mechanical properties are achieved in aluminium alloy by using different strengthening techniques such as age hardening etc. The favourable mechanical properties are explained by revealing the microstructure of corresponding alloy and intermediate phase compounds during formation of corresponding alloy............

Abstract: The present fossil fuel crisis and increasing vehicle population made us to think of alternate fuels. The abundance of the fossil fuels is expected to be exhaust in another 30-40 years. The cost of the fossil fuels is day by day increasing and also the emission from these fuels increases the air pollution. With keeping in view of all the above said points, it is made us to think of alternate fuels for all CI Engines. Among alternate fuels, the Apricot oil blended with Ethanol will promise for substituting the diesel. With pure vegetable oils there is combustion problems and which leads to more emissions in the exhaust. The present investigation evaluates Apricot oil blended with Ethanol in Diesel Engine.............

Abstract: Plain concrete possess very low tensile strength, limited ductility and little resistance to cracking. Internal micro cracks are inherently present in concrete and its poor tensile strength is due to propagation of such micro cracks. Fibers when added in certain percentage in the concrete improve the strain properties well as crack resistance, ductility, as flexure strength and toughness. Mainly the studies and research in fiber reinforced concrete has been devoted to steel fibers. In recent times, glass fibers have also become available, which are free from corrosion problem associated with steel fibers............

Abstract: From the problematic combustion phases for diesel engines, cold start is most one. A large volume of pollutants produced during this period. These high levels of emitted emissions resulted from misfiring and incomplete combustion due to the low engine temperatures. Many variables intervene in, some of it follows fuel properties; others follow lubricant properties and some of it due to engine operation conditions. Injection timing plays a dominant rule in engine start ability in cold and hot weathers.............

Abstract: Vertical tail is a component of the airframe, which is attached to the fuselage at the rear end. It is one of the major components of the airframe. Vertical tail is similar to the wing structure in shape. Rudder attached to the Vertical tail is the control surface, which is used for controlling yawing motion of the aircraft. Deflection of rudder introduces side load on the Vertical tail. Without rudder deflection, there is no aerodynamic load on the Vertical tail. The load due to deflection is the major design load for the Vertical tail. For transport aircraft side gust load is also important from a design point of view............

Abstract: The objective of the present research work is to determine the optimum engine condition that reduces the exhaust emissions of the diesel engine when fueled with jatropha biodiesel and its diesel blends. Fuel injection pressure, engine load and percentage of biodiesel content in the blend were chosen as three influencing control factors on the response parameters: particulate matter (PM), and smoke opacity emissions. Taguchi method was employed to investigate the each control parameter influence and to identify the right optimum combination of parameters on each response parameter............

Abstract: This paper looks into the engineering act of designing and developing new materials for sustainable applications through natural fibre reinforcements and green composites. Composites or composite materials are extending the horizons of designers in all branches of engineering, and yet the degree to which this is happening can easily pass unperceived, consequence being that these materials still need to be engineered to perfection. Natural fibres have recently become attractive to researchers, engineers and scientists as an alternative reinforcement for fibre reinforced polymer (FRP) composites............
