    Land wind turbines “on-shore” are installed in land-based applications, while “off-shore” wind turbines are installed over water. There are some advantages and drawbacks; such as the environmental impact of offshore wind is considerably reduced compared with those onshore; although noise and visual impact are questionable to be problems there are some concerns. For example, there could be an environmental impact such as localized disturbance of the seabed from the noise caused by the turbine underwater. Another fact are that off-shore turbines tend to have larger ratings, because the cost of installation is greater, according…

    ABSTRACT An aircraft is designed based on various wind tunnel testing, computational analysis, previous design experience etc. In most of the aircraft programs the design objective could not be met with the first prototype design itself. Before the induction into the service the aircraft could have undergone many design improvements in order to meet the desired performance. These performance improvements can be achieved by improving the original design in the area of aerodynamics, structure (weight reduction), propulsion and systems (like flight control system, avionics, fuel system etc.). This could be by modifying the original design or introducing new concepts in the design. Due to the obsolence of many technology and growing demand many aircraft program undergone an upgradation program and meets the higher performance demands. Many successful modifications were retrofitted in all their earlier aircrafts and followed in other aircraft programs also. Keywords: Aircraft, aerodynamics, performance improvement program, PIP, propulsion systems…
