Introduction to Launch Vehicle Analysis and Design

Introduction to Launch Vehicle Analysis and Design. Instructor: Prof. Ashok Joshi, Department of Aerospace Engineering, IIT Bombay. Space has always been of keen interest to mankind as it is believed to contain information relevant to formation, existence and continued sustenance of our planet. Space mission is defined as an act of transporting a space object to its designated spot and then carrying out the scientific/technological activities. Transportation of these objects is done through launch vehicles which are important elements of any space mission. Launch vehicles provide the space object with sufficient energy to enable it to set us a desired space mission. The course aims to introduce fundamental principles governing ascent mission trajectory design including the configuration design of launch vehicles. It also aims to present various techniques that help in synthesizing the trajectory and the launch vehicle for specified objectives. (from nptel.ac.in)
