Introduction to Launch Vehicle Analysis and Design

By Prof. Ashok Joshi | IIT Bombay

Learners enrolled: 2193

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

Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Bombay.It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.
