Flying taxis! Getting to Chennai from Bangalore in less than 30 minutes? Building 3D-printed rockets that can launch into space? If you’re wondering if you have suddenly been catapulted into the future, join the club! You are going to be hearing all this and more on today’s Best Place to Build Podcast.
Amrut interviews Prof. Satya Chakravarthy about his journey from student to professor and entrepreneur in the aerospace industry. Prof. Chakravarthy shares his experiences as an IIT Madras student in the late 1980s, his academic path to Georgia Tech for his PhD, and his return to India.
The discussion focuses heavily on Prof. Chakravarthy's entrepreneurial ventures, particularly the E-plane company, which is developing India's first electric vertical takeoff and landing (eVTOL) aircraft. He explains the technical challenges, market potential, and vision for urban air mobility. The conversation also covers the evolution of India's aerospace ecosystem from government dominance to a thriving startup environment, highlighting how the internet and changing attitudes have empowered Indian engineers to build cutting-edge aerospace technology locally rather than seeking opportunities abroad.
Join Amrut as he talks to the professor about his time in the Aerospace department at IIT Madras. The journey from professor to faculty advisor to co-founder in not one but four different companies - The ePlane Company (flying taxis), TuTr Hyperloop, GalaxEye (satellite imaging), Agnikul (3D printed rockets) and starting the NCCRD at IIT Madras. This is an interesting episode for anyone who wonders what our future in Aviation and Aerospace would look like.
“Professor Satya Chakravarthy is just short of a mad scientist (or engineer, if you may). In addition to teaching at IIT Madras and running the National Centre for Combustion Research & Development (NCCRD), he's a compulsive builder. When I asked him if the technology he’s working on can be compared to The Jetsons, his response was that this technology would be better because it would work by itself without any strain on the humans travelling. That sums up his approach to Aerospace and future technology in a nutshell."

Professor Satya Chakravarthy was a student at IIT Madras in the Aerospace Engineering department before going to Georgia Tech University for his Doctorate in Aerospace Engineering. He then came back to teach at IIT Madras. As Faculty adviser to the Hyperloop team, he wondered if it had any applications in the real world. Today, he is the founder of The ePlane Company and co-founder of multiple companies like TuTr Hyperloop, GalaxEye, and Agnikul. He is also the Founder and Head of the NCCRD at IIT Madras which has now built the fifth largest hyperloop vacuum tunnel in the world.
