IntroductionNow-a-days separately over the world use of technology has been increased more than demands. In all aspects technology is surrounded us. Such use of technology comes from the concept of automation. To automate the communication system in the air cleaver connects the era to a new technological world. Helicopter has made the communication easier than before. It is employ even the security purpose juvenilely.Helicopter mainly is used in the defense sector of a country. But today at every university is taking advanced step to do research on helicopter. Helicopter toy is used to do aerodynamic research in university laboratories. Drone is the latest recent research of helicopter.Everything should be automated that is the motive of people of every sphere. Complexity of move direction increases with the demands of them. To select the get parts for a fruit implementation one is to take so many risks and hazards. It is not easy to choose quality fruits to be implemented. Quality product selection butt enhances full process of the product implementation. New research demands new types of parts to buy for latest technology. Latest technology expands the mood to do research more in the advanced level.2. Selection Process of Suitable MaterialsBefore runway a project or product we need to select appropriate materials that are available and appropriate for our plan and design implementation. Some points need to be remembered before buying parts such as costs, availability, acceptability, material properties, environment friendly or not, stressing capability etc. Depending on these properties product is designed and y ields performance. The beat the quality of material the best the performance of the product. Performance evaluation completely depends on these properties.For designing a helicopter the following parts are needed for basic functioning. Such as body, blade, blade shaft, fans, case, rotor, heli base, heli scream etc. These parts are made of aluminum, plastic, carbon fiber, fiber glass etc. All the parts are available at stores. All the parts are bought separately from the near able and tested stores and then assembled. After complete assembling a helicopter gets ready. After doing that rotating parts are set. The political machine code need to be embedded and make the helicopter ready to fly. Maximum helicopter runs with remote control control. If it happens then a remote control need to be bought with higher performance and radio frequence quality. If the remote control efficiency degrades then helicopter will not be operated from remote distance. away control contains some area embedded on the board. The left portion controls the collective control and discipline side button controls the cyclic controls. It also contains throttle stick, direction stick, left and right trims buttons etc.3. Potential Failure of ProductSome critical moments rises after buying the materials. The parts do not show their performances perfectly according to their specifications. Like, for helicopter, a rotor does not rotate according to the code embedded. This tops be wee-wee of the temperature or some other natural effects. If any product says it is 100% efficient it shows 80-90% efficiency in certainity. Some deviation happens each measure. Calculations should be done considering these unavoidable issues.Potential failure contains the metal fatigue and filch and their effects. When fatigue occur the metal get weakened and metal stress capability is lessened. Frequent loading and unloading cause fatigue to the metal properties. Fatigue depends on some other natural criter ia such as temperature, humidity and metal stress. The stress tolerance capability of metal indicates the longevity. High stress tolerance let the metals to be lasted for more time. Steadiness of materials provides services to the developed products.Another effect of failure or damage is creep of metal. Creep stands for deformation. Deformation of particles inside the metal depicts in the microscopic view.4. Sustainable Engineering Aspects of Selected MaterialsAt the time of choosing materials for design engineering nurture should be added to this design. Engineering term increases the value of products. Engineering terms maintain a product with technical aspects. Every materials/parts should be technically evaluated. skilful evaluation makes the product acceptance to all. If a product meets the technical specification perfectly then the product is good for use. Technical specification depicts the product life bout at once. Having higher product evolution life cycle lasting fo r long times.Sustainability aspects of engineering contain four types of aspects. These are very suitable for a design a product and its implementation. These areDevelopment process aspect defines sustainability of a process of product development at initial level. It considers the usage not only of natural but also financial resources. guardianship process aspect defines the sustainability of product during its maintenance time. It occurs until the new system replacement.System production aspect is the sustainability of product as a real product.System usage aspect is the sustainability in the application level of a product as a real life product.5. Practical materials evaluationHelicopter BaseFor violate performance of helicopter base material should be strong and stress free. Corrosion is a real enemy of any metal substance. Base should be designed like a helicopter peck land easily and comfortably. For this design magnesium and aluminum has been selected. The total substance o f the heli base is a potpourri of Magnesium and aluminium. Where the percentage of Aluminum is 2.38% and Magnesium is 97.62% in the aspect of weight. The table showing the percentage of Aluminum and Magnesium is given belowHeli Base Material ListHeli PipeHeli pipe is very of the essence(predicate) portion of helicopter development. It stands with the heli rotor. It helps rotor to move smoothly and swiftly.Helicopter CaseHelicopter case is for carrying the helicopter equipment together. All the equipment can be settled here. The case may be made of aluminum, fiber, plastic or steel.Table for case of helicopterHelicopter RotorHeli rotor is the part that rotates and helps the helicopter to move upward. It rotates horizontally. It depends on the aerodynamic effects. The rotor consists of spider, blade, slider, pitch control rod, mast, damper, scissors assy, extension rod etc. The rotor moves not only horizontally but also vertically. It functions with the decentralized force to move. Using this feature it move left, right, up and down direction.From the above table it is clear a comparison has been done with Nr = 3 and Nr = 4. Column 2 stands for Nr3 and column 3 stands for Nr 4. Column 3 S0 value is less than column 4 where, W value upto Fmax is greater than column 4.6. ConclusionAs helicopter is used frequently in the university researches its parts should be used more carefully. Doped materials can be harmful for product performance and evaluation. Aero dynamic deliberateness should be done very carefully with technical evaluation because if there is an unwanted occurrence from nature the product will face failure permanently. This should be in mind.7. ReferencesBudiyono, T. Sudyanto, H. Lesmana (2008), First Principle Approach to framework of Small Scale HelicopterJ.
