Best Place To BuildProf. Satya Chakravarthy| "Takes off like a drone, flies like a plane"| Ep. 7 | IIT Madras
CHAPTERS
Why IIT Madras is the “Best Place to Build” + Prof. Satya’s many hats
The host sets the premise of the show—meeting builders at IIT Madras—and introduces Prof. Satya Chakravarthy’s roles across academia, research infrastructure, and multiple deep-tech startups. The episode’s core theme is building world-class engineering from India, spanning aviation, space, and mobility.
IITM student life (1987–1991): insti lingo, culture, and how campus has changed
Prof. Satya reflects on his BTech years in Aerospace at IITM, describing a more laid-back, personal campus culture with strong “insti lingo” and informal student–faculty interactions. They also touch on student leadership roles then vs today’s resume-oriented POR culture.
Georgia Tech for MS/PhD: pipeline, mentors, and seeing the world beyond IIT
He recounts moving to Georgia Tech for graduate studies and how IITM–Georgia Tech links formed through faculty and recommendation pipelines. The conversation frames this as part of a broader global exposure that later feeds into building ambitious programs in India.
Aerospace vs CS: “Follow your heart” in the passion vs paycheck dilemma
Addressing the common career dilemma among JEE aspirants, Prof. Satya argues for choosing based on genuine interest, especially given expanding opportunities across domains. He reframes uncertainty as universal—no one fully knows the future—so passion and adaptability matter most.
The ePlane Company: what eVTOLs are and the design philosophy (drone takeoff, plane flight)
Prof. Satya explains eVTOLs as aircraft that take off/land vertically but cruise like planes, positioning them as practical shared-mobility rather than Jetsons-style personal gadgets. ePlane’s differentiator is compact, short-wing designs to operate in tight urban spaces.
Performance, economics, and the battery barrier: range, energy density, and power draw
They dig into the physics and tradeoffs limiting electric aviation: batteries’ energy density and the intense power demand during vertical takeoff/landing. Prof. Satya compares batteries to fuel, discusses engineering levers (aerodynamics, lightweighting, motors), and why hybrid systems increase complexity and cost.
Making the “crazy idea” believable: how ePlane sells to investors and recruits talent
Prof. Satya describes how deep-tech persuasion works in India: investors often need global precedents before backing a new category. On hiring, he outlines how India’s aerospace talent pool has matured through MNC R&D and manufacturing, creating engineers eager to build complete aircraft, not just parts.
From bootstrap to Series B: ePlane’s milestones, timeline, and 2026 commercial goal
He details ePlane’s progression from winged drones to subscale prototypes and now to building a passenger prototype, enabled by fundraising. The path to market is tightly coupled with testing and certification, with commercial flights targeted for late 2026.
Aviation regulations: why certification dominates timelines (and why it’s worth it)
The episode emphasizes that civil aviation is regulation-heavy for good reason—every component change can require compliance work. Prof. Satya contrasts aviation’s safety record with road transport, arguing strict standards are a feature, not a bug, especially for new aircraft categories.
Agnikul Cosmos: 3D-printed rocket engines, test infrastructure, and the long deep-tech grind
Prof. Satya explains Agnikul’s core innovation—highly integrated 3D-printed engines with simplified interfaces—and the extensive ground test infrastructure built at IITM’s Thaiyur/Discovery Campus. They discuss the long horizon (2017–2024) and how deep tech demands both impatience to start and patience to finish.
GalaxEye Space: SAR + EO fusion to image Earth 24×7 (no more excuses)
GalaxEye’s proposition is fusing radar imaging (SAR) with optical/multispectral imaging and ML to produce useful Earth observation even through clouds and at night. The result is a step-change in usable data availability and efficiency, oriented toward global markets and commercial use cases.
TuTr Hyperloop: feasibility, affordability, and the Chennai–Bangalore in ~15–25 minutes vision
The Hyperloop segment reframes the technology as ‘maglev + vacuum’ that becomes viable when designed for Indian affordability and select high-demand corridors. Prof. Satya argues that while capex is high, operating costs can be slashed enough to compete with flights on key routes at disruptive ticket prices.
World-class testbeds at IITM Thaiyur/Discovery Campus: Hyperloop tube, rocket stands, wave basin, fuels
Prof. Satya describes Thaiyur as a build-focused ‘wonderland’ that concentrates large-scale experimental infrastructure in one place. The campus hosts full-stack testing for rockets and Hyperloop, ePlane build activity, ocean engineering facilities, and waste-to-fuels projects—creating a magnet for global teams and collaborators.
NCCRD (combustion center): why it was built, what it studies, and how it sustains itself
He explains how early laser diagnostics work attracted strategic-sector and industry interest, leading to the creation of NCCRD as a multi-domain combustion umbrella. Success is defined not just by facilities, but by sustained industry collaboration, funding continuity, research output, and training large cohorts of PhDs.
Drop tower at IIT Madras: microgravity research, global community, and what it enables
Prof. Satya walks through IITM’s ~38 m drop tower design, delivering ~2.3 seconds of microgravity, and the kinds of research it supports. He connects the drop-tower philosophy with Hyperloop: creating space-like or extreme environments on Earth to accelerate experimentation and attract global researchers.
The joy of engineering + closing advice: plan 5–10 years, stay adaptable, switch when needed
In the wrap-up, Prof. Satya explains that building real products (like an aircraft) is his current source of joy because it demands broad, end-to-end engineering beyond narrow research slices. His advice is to keep a default plan over a 5–10 year horizon, evaluate new opportunities against it, and switch or dovetail when it truly improves the trajectory.
