NPTEL

Introduction to Launch Vehicle Analysis and Design

NPTEL and Indian Institute of Technology Bombay via Swayam

Overview

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 up 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.
INTENDED AUDIENCE :
Undergraduate / postgraduate students, participants from industries involved with tasks related to space agencies, personnel from defence establishments engaged with missile system configuration design, teachers of engineering colleges having aerospace as the discipline.PREREQUISITES : No specific pre-requisites are necessary. However, basic understanding of rigid body mechanics, fluid mechanics, and thermodynamics is desirable.INDUSTRIES SUPPORT :None
