The hydraulic, electrical, avionics and ECS systems are to regular monitoring and maintain is very much required, where the doors and covers also included in an war aircrafts. The covers of such aircrafts are fastener by TRIDAIR attachments, depends upon the load acting on such covers can be used to determine the number of fasteners required under different parameters(weather). The work deals with design and analysis of aircraft fuselage by using carbon fiber composite (CFC) under bending loads and given boundary conditions, CATIA V5is used as modeling tool to model cover and MSC PATRAN and NASTRAN is used for analysis. To validate the results obtained from the NASTRAN, the theoretical calculations are done, CFC covers are better withstanding capacity compared with metallic and the weight on cover is reduced nearly 50% as compared to metallic cover.

Nowadays, the main focus on renewable energy and different fuels has increased because of increasing oil costs, environment pollution, and additionally concern on protective the nature. Biodiesel is non-toxic, biodegradable, high Lubrication ability, extremely renewable, and its use thus produces real reduction in petroleum consumption and carbon dioxide (CO2) emissions. Though biodiesel has several benefits, however it still has some properties got to improve, like lower calorific value, lower effective engine power, higher emission of N oxides (NOX) and maximum sensitivity to low temperature. An effort has been taken to review performance and emission characteristics of a CI engine fueled with biodiesel and diesel fuel using EGR. All the experiments were conducted on a single-cylinder, four-stroke, water cooled, indirect injection CI engine at the engine full load operation and constant engine speed of 1500 rpm. The engine performance and efficiency obtained in biodiesel case were less that can be attributed to lower calorific value of biodiesel. CO and UHC emissions for biodiesel were not up to that of diesel fuel. However, it absolutely was observed that Nox emissions for biodiesel were on top of that of diesel fuel. Exhaust gas recirculation (EGR) may be a terribly effective technique to reduce Nox emissions from a CI engine. In this study the venturi type EGR system was used. Exhaust gas recirculation (EGR) is effective technique to minimize Nox emission from diesel engines as a result of it permits lower flame temperature and oxygen concentration within the combustion chamber. Some studies succeeded to minimize the Nox emission from biodiesel by EGR however they discovered increasing soot emission. Soot emission, NOX, CO2, carbon monoxide (CO) were recorded and various engine performance parameters were also evaluated.

One of the most persistent problems of today is water scarcity. It has been estimated that one in three persons will face water scarcity by the year 2025 in India according to International Water Management Institute (IWMI 2013 report) or around 2.7 billion people worldwide by the same time (UN Report 2016). Water resources are abundant, but they are unevenly distributed: 97% of water available on earth is related to the seas and oceans, 2.97% as polar ice caps while the remaining 0.03% is surface waters. In this report we are going to deliberate about one of the water driven activity of day to day life of human being i.e. washing of clothes which requires lot of water and all this water is wasted and gets mixed with other waste water and discarded. The need for increased water requirement for the growing population in the country is generally assumed, without considering whether available water resources could meet these needs in a sustainable manner. The question about from where the extra water is to come, has led to this study. An evaluation of low cost treatment using activated carbon and Nylon rope has been assessed and the result revealed that nylon filter beds which were used instead of dual media filter and activated carbon showed better performance on effluent of washing machine.

The biodiesel is a renewable alternative to the fossil diesel as the properties of the bio-diesel is like to the fossil diesel. However, the bio-diesel have lower volatility and has lower oxidation stability. Hence, in this work we have chosen the Black seedoil, clove oil + Pg and turmeric oil as a natural additive for the honge biodiesel. Anti-oxidative properties and stability of ethanolic extracts of Black seed oil, clove oil + Pg and turmeric oil is studied. Along with that constituent’s black seed,turmeric oil and clove oil+ accounting a 90% of essential oil content which preferred as additive to the biodiesel. Also, we calculated the effect of these additives on the fuel properties of the bio-diesel and its impact on compression ignition thermal efficiency and exhaust emissions. The additive concentration ratio of binary anti-oxidants is the key factor to get best synergy for greatest stabilization. In an engine, temperature has reaction completeness is the most critical fuel quality parameter as well as engines’ durability and reliability. By adding natural additives to the biodiesel, as the amount of concentration increases it led to reduction in hazardous emissions through engine exhaust like NOx, CO2, HC s, CO decreases. But the O2 content increases in a engine exhaust. All these emissions are as compared with conventional diesel which gives the best results for lowering the environmental pollution.As the proper qualities of biodiesel blends met by adding these naturally available additives, these biodiesel blends can be used in most modern engines.

Chain sprocket is one of the important component of chain drive for transmitting power from one shaft to another shaft. The front sprocket drives the rear sprocket via chain connection. In this study of the stress of chain drive, existing sprocket of mild steel is compared with the sprocket of cast iron material. It has been achieved by using Ansys 18.1, by applying torque in to the model of sprocket. Then model is made by the commands in Solid Works 2016 and geometrical selections in part design module. Pre-processing like meshing is carried in Ansys 18.1. With insertion of that model into the Ansys 18.1 for Post-processing with different properties of mild steel we found different values of Von-Misses stress, total deformation and equivalent elastic strain. With same model of sprocket, analysis has been carried out in Ansys 18.1 with different properties of cast iron.
