Glider 3 - Assignment Example The glider fuselage has a rounded nose and sleek thus allowing easy flow of air can flow efficiently around it. The feature is also enhanced by the presence of the tapered body of the fuselage (Yechout & Morris, 2003). The wing design for the glider represents intrinsic part of the glider. It has various arrangements of braces, ribs, edges and many other parts designed to strengthen the wing part of the glider. The glider wing has planform exhibiting high aspect ratio, variable and tapered aerofoil shape. The wing allows for straight model of sweeping by entailing wing motion through the right angles to anticipated line of flight. The selection of the type of the glider wing focuses on allowing of low-speed design. The wings provide essential lift force, and therefore is most imperative lift-producing element of the glider (Yechout & Morris, 2003). The four spars mainly provide the lateral strength for the wing. Ribs are attached to the spars to complete the structural parts. There is a rising angle is called the dihedral which aids in keeping the airplane from rolling suddenly while on flight. AOI or the angle at which the wing is linked to the fuselage is mainly 5o. The wings have variable b and c features on it. The empennage has rudder, vertical stabilizer, engine pylon, elevator and horizontal adjustable stabilizer as the main typical parts. There is well designed to provide stability and enhanced control for the glider. The main two parts entailing the empennage includes vertical stabilizer otherwise called fin on which the rudder is normally attached. There is another segment called horizontal stabilizer on which the elevators are conventionally attached. The typical stabilizers facilitate proper pointing of the glider to the wind as normally, when the tail section of the glider swing to any side, the wind thrust against the tail sides and surfaces. This action maintains the proper place of the

Life Cycle Assessment - Essay Example In these way sustainable enterprises, therefore is one that contributes to sustainable development by delivering simultaneously economic, social and environmental benefits so called triple bottom-line (Elkington, 1994). The global challenges associated with sustainability, viewed through the appropriate set of business lenses, can help to identify strategies and practices that contribute to a more sustainable world and simultaneously, drive share holders value (Hart and Milstein, 2003). The sustainable value framework developed by Hart & Milstein (2003) creates four- quadrant contains sustainability vision clean technology, pollution prevention and product stewardship. Now to sustain the business on the long term basis, products must be more energy efficient, reduce end of life waste, decrease pollution etc. To develop this kind of product, we have to promote environmentally conscious design which promotes energy efficient and environmentally sensitive energy generation. Environmentally conscious design works within the economic and technological constraints to develop and use new technologies that are sustainable in the long run. Environmental conscious designs of the products are the necessity of the time and to develop these products, we face could face numerous problems as well as challenges. Now to develop a product this is environmentally conscious and have the design to support it is the subject of various areas. The process of designing such products is very cumbersome. There is continuous process to improve the design of the products. In the process of development of products, industries are including the waste handling in the scope of process and marking efforts to reframe or design processes which can use the existing waste facilities and to avoid the need to invest in new treatment facilities. In the process of design reevaluation, some efforts have been taken to integrate materials integration techniques as a cost effective ways of reducing pollutant emissions. In the process of developing environmentally conscious subjects, one must assess environmental impacts through life cycle assessment. In the lifecycle assessment (LCA), we must evaluate environmental impacts on the every stage of development of the products i.e., from starting to end. More and more academics have applied life cycle assessment to all the development of industry in Europe. LCA has represented by life cycle problem. Recently LCA represents a new way of thinking about the industries results into most cost effective development. The use of natural products, new way applied to produce time, use of raw materials and natural resources which ultimately minimize waste and adverse impact on people as well as natural environment. In the life cycle process, products entire life cycle from design to final uses and disposal as well as reuse of raw materials has been included. LCA shows a new way to think about manufacturing of the produc6ts which includes the most efficient and productive use of raw materials and natural resources. It is a process which depends on minimizing wastes, avoiding adverse impact on workers and on the natural environment. In the LCA application, we analyze the complete life of the product i.e. from design, raw material and natural resou
