Design and analysis of nozzle for reverse thrust braking system

Abstract

In age of automotive, lakhs of vehicles running all around and day today the vehicles are being added up. In countries like India, due to these numerous vehicles, accidents occur frequently. On an average 400 fatalities a day happens in India due to accidents, that is, every 5 minutes a person is fatally injured due to accident. These accidents might be due to several reasons but the main reason is inability of the driver to control the vehicle in extreme conditions, but the effect of accident could have been reduced by applying brake effectively. So, there is a serious urge to develop an intelligent emergency braking system. The advancement in automation had led to the collaboration of both entities, Automation and Automotive to give an ultimate safety braking systems like ABS, EBA etc. The present study aims to design an advanced emergency braking system using the concept of reverse thrust. This paper intent to collaborate the reverse thrust braking with the existing automatic pneumatic braking system to increase the efficiency of braking in extreme conditions and to ensure the safety of driver and the vehicle. To develop a reverse thrust braking system, it is necessary to determine the components and its arrangement to produce the required thrust. In the following paper, nozzle is designed and analyzed based on the defined boundary condition to produce the required thrust. By application of thrust braking system, the stopping distance of the vehicle is significantly reduced based on the capacity of thrust that a nozzle can produce and also acts as an emergency automatic braking system to save lives. Reverse thrust braking system will be of greater use if the coefficient of friction is low. Designing and analysis software are used for the purpose of nozzle design and other requirements.
