Fundamentals of Theoretical and Experimental Aerodynamics

By Prof. Arnab Roy | IIT Kharagpur

Learners enrolled: 1838

This course is introductory in nature and expected to impart firsthand knowledge of Aerodynamics. It combines fundamentals of theoretical and experimental aspects of Aerodynamics without making it too intense and detailed. After successful completion of this course the student should be well prepared for more advanced courses in the discipline.
With ever increasing use of Aerodynamics in a wide gamut of applications like drones, UAVs, micro air vehicles, automobile aerodynamics, sports aerodynamics, industrial aerodynamics, defence and space, it is essential to understand the basics or quickly refresh the fundamental concepts of Aerodynamics while working on any of the above applications. This course exactly fulfils that need.
I would like to once more emphasize that the primary intention of this course is to create a familiarity about Aerodynamics. It is not intended to prepare someone for research but induce the excitement and enthusiasm to pursue it further.

PRE-REQUISITES: Nill

INTENDED-AUDIENCE: Aerospace Engineering/ Mechanical Engineering

INDUSTRY-SUPPORT: This course should suit as an introductory Aerodynamics course for new recruits in organizations like National Aerospace Laboratory (NAL), Defence Research and Development Laboratory (DRDL), Aeronautical Development Agency (ADA), Aeronautical Development Establishment (ADE), Hindustan Aeronautics Limited (HAL) and private/ multinational aerospace firms like Boeing, Airbus etc. It should be useful for IAF

engineers and pilots as well.

IIT Kharagpur

1. I am currently working as Professor at the Department of Aerospace Engineering, IIT Kharagpur. The above weblink provides my research details. 2. I have taught various courses covering Aerodynamics, introductory and advanced courses in CFD, Wind Tunnel Design and Testing as well as a few courses in Aerospace Propulsion at IIT Kharagpur to UG/ PG and PhD students.On almost all occasions I have received an overall student feedback rating between 4 and 5 (on a scale of 5). In all, I have about 16 years teaching experience at UG and PG levels combined. 3. My research interests include computational and experimental fluid dynamics. I am also involved in aerospace propulsion research. I have undertaken and executed projects for different organizations like AOARD (Japan), Boeing (USA), AR&DB, DLJ-DRDO, RDSO, ISRO, DST etc 4. I have delivered several CFD related invited lectures at GE Aviation JFWTC, Bangalore (2019); CFD Workshop, BITS Pilani Hyderabad campus (2016); 13th Aeronautical Society of India Annual CFD Symposium at IISc Bangalore (2011),Indo US INDUS-MAV Workshop at Bangalore,organized by NAL and ADE Bangalore (2009) etc.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.

The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).

Date and Time of Exams: 23 April 2022 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.

Registration url: Announcements will be made when the registration form is open for registrations.

The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.

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 8 assignments out of the total 12 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.
