The present work describes various automotive noise&vibration sources and their contribution. Noise and vibration reduction technique is studied through energy flow path. Various international and Indian standards for vehicles consider two types of noise measurement i.e. pass by noise and stationary noise. This paper discusses the appropriateness of SN test for in use vehicle. A methodology for interior noise source identification and its analysis is descried. Two vehicles of same class but of different makes were compared and evaluated for interior noise and vibration levels. The effectiveness of the firewall, silencers and engine mounts are checked and compared. The correlation between pressure and vibration levels of different sources with acoustical and structure transfer path are studied. Basic causes, design guidelines and validation techniques using lab simulation and data acquisition are discussed. Application of damping technology using viscous materials to control noise and vibration in vehicles is described.Keywords

The paper basically explains a use of solar energy in Aviation&Aero planes. Due to declining of petroleum products&various fuels need of an alternate non-conventional source of a fuel is required. Alternative energy sources focusing on replacement fuels that will reduce carbon dioxide emissions. Solar energy is one the best source which cannot deplete. Aviation history is taken into account for design of Solar impulse. Solar impulse is the case study that how solar energy can be used as a fuel in aero planes. The basic terms used in the Analysis of the Solar impulse are briefly explained. Technical data related to Solar impulse is picturised. Afterwards, the use of solar energy in Aviation base is analyzed. Current limitations are also considered so as to overcome them in future design. Solar powered aircraft capable of continuous flight was a dream some years ago, but this great challenge has become feasible today. Quite a few manned and unmanned solar powered aircraft have been developed and flown in the last 30 years. The research activities carried out till now have been mainly focused on flying wings or conventional aircraft configurations, with a great emphasis on the technological aspects. Solar powered aircraft uses solar panel to collect the solar radiation for immediate use but it also store the remaining part for the night flight. The paper deals with the current state of art of empower the aviation industry with solar power and the shortcoming and the future aspect. Conclusion of the Seminar report is finally stated.Keywords
